4. L:\1_instalac\1_instalirano\linux\2_oralinux\oracle_linux_7_6\001_oralin_7_6_V980739-01.iso 4,5 GB
### Instalac (CLICK RIGHT CTRL TO FREE MOUSE !!)
#### Swap 2 x memory = eg 12 GB
min. 8 GB for swap - required by Oracle 11g DB
Select Virtual Machine oralin81 that you just created. Click on the green Start icon on the top of vbox screen.
Select 'install Oracle linux' and click Enter key. Select language to use during the installation process.
Only ora Linux: Select **Server with GUI**. Minimal installation option is the installation without GUI.
Select :Add ons for selected environment and choose :

### update oralin 7.6 to 7.8 os from sys -> sw
su - or sudo bash
yum update
**if ERROR see 002_instalac02_2ERROR_add_guest_add.jpg**
cd /var/log
ls
gedit vboxadd-setup.log.highest_ver_eg_4
**look for "please install"... shift+ctrl+c them**
yum install zlib-devel
yum install elfutils-libelf-devel
Right click on desktop then Display setings 1920 1200 (16:10) then **right ctrl+f works**
Add the kernel parameter divider=10 to select a guest kernel timer frequency of 100Hz to avouid High CPU load.
cat /boot/grub/menu.lst
### Uninstall Apache
1. sudo yum erase httpd httpd-tools apr apr-util
rpm -qa | grep httpd - to check if httpd* packages are uninstalled
2. gedit /etc/sysconfig/iptables
Find and remove line as follows:
```
## open port 80 /443 ##
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
```
3. Restart iptables: service iptables restart
4. You need to repeat the same steps for ip6tables ? IPv6 packet filter by editing
/etc/sysconfig/ip6tables
#### How do I check if a service is running or not
systemctl status httpd.service or systemctl status httpd
sudo systemctl enable httpd.service
command will create approriate symbolic links to the /usr/lib/systemd/system/httpd.service
if you want to recreate symbolic link for enabling service :
systemctl reenable httpd.service
To disable a service to be not started automatically at boot time:
sudo systemctl disable httpd.service
This command will remove appropriate symbolic links to /usr/lib/systemd/system/httpd.service
sudo systemctl start httpd.service
sudo systemctl status httpd.service
sudo systemctl restart httpd.service
To only reload the configuration of one service without interrupting their execution:
sudo systemctl reload httpd.service
<br /><br />
I tested also Centos 7.3 and Mint 18.2 Cinnamon - do not work for me (after OS update - problems with booting same as with oralinux 7.3). To install DB 11g XE I ended with oralinux 7.3 - works better than 7.2.
## 2\.2 VBoxGuestAdditions.iso
This image file is located in the installation directory of VirtualBox:
C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso
After installing Linux on VirtualBox we need install VBoxGuestAdditions because of **not working** features :
**Resolution is bad, Auto-Resize (rightctrl+f), Drag-Drop, Clipboard sharing**
To install the Guest Additions for a particular VM, you mount this ISO file in your VM as a virtual CD-ROM and install from there.
su -
yum update
1. remove Linux .iso from IDE controller, put VBoxGuestAdditions.iso in IDE controller or :
Start Linux > Devices ->Guest add.
or :
1. `C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso`
2. start Orcle VM VirtualBox Manager -> click oralin76 Virtual Machine (powered off) -> click icon Settings
-> click Button 'Storage' and add a new 'Controller: IDE' for virtual DVD device, put iso above in it
3. start Oracle Linux 7.6 and **right click VBoxGuestAdditions icon -> open in terminal **
**if ERROR clipboard sharing not working use insteadd ver 6.1.4 older :**
L:\1_instalac\1_instalirano\5_virtualbox\VBoxGuestAdditions_6.1.2.iso
**if ERROR install VBoxGuestAdditions.iso (see 002_instalac02_2ERROR_add_guest_add.jpg)**
1. cd /var/log
2. ls
3. gedit vboxadd-setup.log.highest_ver_eg_4 (I tried 4 times)
**look for "please install"... shift+ctrl+c them**
4. yum install zlib-devel
5. yum install elfutils-libelf-devel
6. repeat install VBoxGuestAdditions.iso
Right click on desktop -> Display setings -> 1920 x 1200 (16:10) then **rightctrl+f works**
>see chapter 4, Guest Additions, page 83/391
>software packages which can be installed inside of supported guest
>systems to improve their performance and to provide additional integration
>and communication with the host system.
> - automatic adjustment of VIDEO RESOLUTIONS,

### 3\.1 How to add user into sudoers in Red Hat Linux server
to use "sudo"
su -
cd /etc
ls -alF
chmod +w sudoers
gedit sudoers
\# scroll down in file and find line (root ALL=(ALL) ALL)
\# right there add this for the user (example userid: roman)
root ALL=(ALL) ALL
ssoralin73 ALL=(ALL) ALL
Exit & Save
chmod -w sudoers (make the sudoers READ-ONLY again)
Use cases:
```
Lauch bash with elevated privilges, using your own password:
sudo bash
Lauch shell as user root, with root's password:
su - root
Lauch shell as user root, with your own password:
sudo su - root
```
How to elevate privileges to root in bash and return back?
```
sudo with heredoc syntax:
possiblevariable=something
sudo /bin/bash <<EOF
cd /somedir
pwd
commandasroot1 "$possiblevariable"
commandasroot2
EOF
nonrootcommand (and not in /somedir)
[ora@localhost ~]$ sudo bash <<EOF
cd /tmp
pwd
EOF
------------- outputs :
[sudo] password for ora:
/tmp
how variables substitution work in heredoc:
[ora@localhost ~]$ sudo bash <<EOF
cd /tmp
echo $PWD; echo \$PWD
EOF
[sudo] password for ora:
/home/ora
/tmp
how you can get output into variable
[ora@localhost ~]$ variable=$(sudo bash <<EOF
cd /tmp
echo $PWD; echo \$PWD
EOF
)
[ora@localhost ~]$ echo $variable
/home/ora /tmp
[ora@localhost ~]$
tee command read from standard input (such as keyboard) and write to standard output (such as screen) and files :
echo 'text' | sudo tee -a /path/to/file -a OR --append
echo '192.168.1.254 router' | sudo tee -a /etc/hosts
```
1. su and sudo are two very different ways to **escalate privileges**, but in the end both allow you to run commands as your target user - in your case root.
2. If you are trying to run a command as another user, **sudo will ask for your password**, su will ask for the other user's password.
3. sudo is designed to let unprivileged users run specific commands as a different user, and so has a configuration sudoers file **/etc/sudoers** which lets system administrators decide *which users can run which commands as which other users*. IE it has fine grained permissions. These permissions can be granted and later revoked.
4. su also lets you run a command as another user, you need to know his (eg root usr) password, but **su isn't designed with the same fine grained permissions**. If you have the other user's password you can do anything as that user. The only way to revoke that access is to change the other user's password.
5. The main difference between sudo bash and sudo -s is that -s is shorter and lets you pass commands to execute in your user's default shell.
Far more commonly, you give -s alone, so it just runs your user's shell interactively. In that mode, it differs from sudo bash in that it might run a different shell than bash, since it looks first in the SHELL environment variable, and then if that is unset, at **your user's login shell setting, typically in /etc/passwd**.

https://wiki.centos.org/HowTos/SELinux
'chcon' command may be used to change SELinux security context of a file or files/directories in a similar way to how 'chown' or 'chmod' may be used to change the ownership or standard file permissions of a file.
Using Apache as an example, suppose you want to change the DocumentRoot to **serve web pages** from a location other than the default /opt/lampp/htdocs (/var/www/html/) directory. Assume we create a directory (or maybe a mount point) at /html/ and create an index.html file there:
```
mkdir /html
touch /html/index.html
ls -Z /html/index.html
outputs : -rw-r--r-- root root user_u:object_r:default_t /html/index.html
ls -Z | grep html
drwxr-xr-x root root user_u:object_r:default_t html
```
We see that both the directory /html/ and file /html/index.html have the **security context type: default_t**. If we start our web browser and try to view the page, SELinux will properly deny access and log the error because the directory and file(s) have the wrong security context. We need to set the **correct security context type for Apache of: httpd_sys_content_t**.
chcon -v --type=httpd_sys_content_t /html
context of /html changed to user_u:object_r:httpd_sys_content_t
chcon -v --type=httpd_sys_content_t /html/index.html
context of /html/index.html changed to user_u:object_r:httpd_sys_content_t
ls -Z /html/index.html
-rw-r--r-- root root user_u:object_r:httpd_sys_content_t /html/index.html
ls -Z | grep html
drwxr-xr-x root root user_u:object_r:httpd_sys_content_t html
Equally we could have set both in one go using the -R recursive switch:
chcon -Rv --type=httpd_sys_content_t /html
Modifying security contexts in this manner will persist between system reboots but only until the modified portion of the filesystem is relabeled. This is a not uncommon operation and the proper solution, after testing, is to write a local custom rule (a so-called Policy Module) and merge it into the base local rules. This will be an additional rule on top of the 200+ rules mentioned above. To make the security context changes permanent, even through a complete filesystem relabel, we can use the SELinux Management Tool or the 'semanage' command from the command line:
semanage fcontext -a -t httpd_sys_content_t "/html(/.*)?"
to add a file context of type httpd_sys_content_t for everything under /html.
```

#### save confign file and create a Samba shared folder. Then, restart Samba services
1. mkdir -p /etc/samba/anonymous mkdir -p /samba/anonymous
cd /samba
chmod -R 0755 anonymous/
drwxr-xr-x. 2 root root 6 4. Jun 16:31 anonymous/ --already was
chown -R nobody:nobody anonymous/
ls -alF
drwxr-xr-x. 2 nobody nobody 6 4. Jun 16:31 anonymous/
chcon -t samba_share_t anonymous/
```
systemctl enable smb.service
systemctl enable nmb.service
systemctl restart smb.service
systemctl restart nmb.service
```
Turn on the Samba server and make sure it starts automatically on reboot.
service smb start
systemctl enable smb.service
or chkconfig smb on
service smb restart
Redirecting to /bin/systemctl restart smb.service
You can check samba services by running ps -eaf | grep smbd; ps -eaf | grep nmbd
Now go to the windows Run prompt and type
\\yourhostname\anonim.
\\ssvbox\anonim
\\10.0.2.15\anonim and 10.0.2.2
Thats it!! You will be able to access anonymous shared drive by now.
Windows cant communicate with the device or resource (10.0.2.15).
The computer or service you are trying to reach might be temporarily unavailable.
If this doesnt connect to the shared folder make sure your firewall services
are stopped and try again. You can run below commands to stop the services.
service firewalld stop -----Redirecting to /bin/systemctl stop firewalld.service
service iptables stop ---- Unit iptables.service not loaded.
Now test shared folder by creating a sample text file on linux machine
and opening it on windows machine.

Advanced sharing settings. Make sure that in the Private network profile section the following options checked:
Turn on network discovery + Turn on automatic setup of network connected devices;
Turn on file and printer sharing;
no more Allow Windows to manage homegroup connections (recommended).
Then enable the following options in the All networks section:
Turn on sharing so anyone with network access can read and write files in the Public folders;
Turn off password Protected Sharing (if you trust all the devices in your network);
Thus, you can open anonymous network access to your computer. So, when you enable this option, you must correctly set the permissions on the shared network folders and printers.
If there are legacy network devices in your network (old Windows version, Samba shares, NAS devices), enable the option ?Enable file sharing for devices that use 40-bit or 56-bit encryption?.

Physical address (MAC): 50-3E-AA-08-23-F8
Starting with Windows 10 1709 and Windows Server 2019 (both in Datacenter and Standard editions), the **unsafe SMBv1 protocol is disabled** by default because of CVE-2017-0144 (remember the WannaCry ransomware attack, which was implemented through the SMBv1 vulnerability), as well as **anonymous (guest) access to network shared folders**.
Win10 Settings -> Network and Internet -> Ethernet (or select Wi-Fi, if you are connected to a local network through a wireless connection). Click the **"Network" icon** and verify that **"Private" ee Make this PC discoverable option is enabled**.
#### ipconfig /flushdns
To enable the Network Discovery traffic on Windows 10 Defender Firewall, you must run the following command in the elevated command prompt:
#### netsh advfirewall firewall set rule group="Network Discovery" new enable=Yes
Or you can enable the network discovery traffic in Windows Firewall with the PowerShell :
Get-NetFirewallRule -DisplayGroup "Network Discovery" -Enabled True -Action Allow -Direction Inbound
Also, you can manually enable the Network Discovery protocol for at least the Private network in the Windows Defender Firewall settings (Control Panel\All Control Panel Items\Windows Defender Firewall\Allowed apps).
In some cases, Windows computer may not be displayed in the network environment due to incorrect workgroup settings. Try to re-add this computer to the workgroup. Go to the Control Panel -> System and Security -> System -> Change Settings -> Network ID.
If these tips did not help, and the computers in the workgroup are still not displayed, try to reset the network settings (Settings -> Network and Internet -> Status -> Network Reset).
You can also reset the network settings and firewall rules with the commands:
netsh int ip reset reset.txt
netsh winsock reset
netsh advfirewall reset
Then you need to reboot the computer.
In some cases, you need to completely remove your network adapter using the Device Manager (run the **devmgmt.msc** console -> Network Adapters -> your network card -> Delete device).
Then restart your computer. Windows should automatically detect your network adapter and install the appropriate drivers. In this case, all old protocol settings for the network card will be reset.
Also, check whether the following services are running (they should be in the automatic startup state to correctly display your network environment). Run the **services.msc** console and check the services state:
1. FdPHost ? Function Discovery Provider Host (responsible for other computers discovering on the network);
2. FDResPub ? Function Discovery Resource Publication (allows other computers to detect your device on the network);
3. Dnscache ? DNS Client; - already is automatic and started
4. SSDPSrv ? SSDP Discovery;
5. Upnphost ? UPnP Device Host.
In some cases, third-party anti-viruses and firewalls can block NetBIOS name resolution requests, WDS and broadcast DNS queries (there was definitely a problem with ESET NOD32). Try to temporarily disable your antivirus/firewall and check if the network discovery works properly on your Windows 10 device.

## 6\. Access Linux fwphp site from Windows (with URL)
http://oralin76/fwphp/www = fwphp site on vbox PC oralin76
>**This site can?t be reached**
>**ERR_CONNECTION_REFUSED** why ? Firewal
Same for http://192.168.5.13/fwphp/www
**https://stackoverflow.com/questions/5524116/accessing-localhost-xampp-from-another-computer-over-lan-network-how-to**
https://www.ionos.com/digitalguide/hosting/technical-matters/err-connection-refused/
`$> netstat -an | grep "LISTEN " if outputs this : tcp 0 0 127.0.0.1:3000 0.0.0.0:* `
Only 127.0.0.1:3000 is listed in netstat output meaning **server is listening on the localhost interface only**, ee you won't be able to access it from a remote computer.
Use "0.0.0.0" - I believe this acts as a wildcard, now allowing for public resolution via the domain name and it also works with "localhost". Here's a link to a serverfault page on the 0.0.0.0 topic:
https://serverfault.com/questions/78048/whats-the-difference-between-ip-address-0-0-0-0-and-127-0-0-1
1. chances are you need only do http://192.168.5.13 or http://oralin76
2. if 1. doesnt work,may be firewall running on your computer - work out how to add port 80 to it to let other machines in.
In Windows : Control Panel > Windows Firewall > Allow an app through Windows Firewall > Allow another app > Browse to: XAMPP/apache/bin/httpd.exe and allow it (see https://www.tomshardware.com/news/how-to-open-firewall-ports-in-windows-10,36451.html).
3. or httpd.conf is only listening on 127.0.0.1
<br /><br />
### 1. Set up a virtual host
See J:\awww\www\zinc\img\img_big\site_on_LAN_or_WEB.png :
1. see (1) in site_on_LAN_or_WEB.png - **J:\xampp\apache\conf\extra\httpd-vhosts.conf** :
Prepare Web server on your computer for handling requests to localhost and dev1 sites. We provide name of Virtual Host and root/main folder of localhost and dev1 websites.
```
#### First VirtualHost section is default or fallback virtual host (testing site),
#### used f or all requests that do not match **ServerName or ServerAlias**
#### in any <VirtualHost> block.
#### 8083 0r 80 :
<VirtualHost *:8083>
DocumentRoot "/xampp/htdocs/"
ServerName localhost
</VirtualHost>
#### sets up a virtual host named dev1 (development site)
#### To see http://dev1:8083/fwphp/www/ (dev1 is apache virtual host) :
<VirtualHost *:8083>
DocumentRoot "J:/awww/www/"
#### on oralin76 PC : oralin76.sspc (symfony.local) :
ServerName dev1
</VirtualHost>
```
### 2. Configure your hosts file
For the client (your browser in that case) to understand what dev1 means, you need to edit the hosts file on your computer. Everytime you type an URL in your browser, your computer tries to understand what it means! dev1 doesn't mean anything for a computer. So it will try to resolve the name dev1 to an IP address. It will do this by first looking into the hosts file on your computer to see if he can match an IP address to what you typed in the address bar. If it can't, then it will ask DNS servers. The trick here is to append `127.0.0.1 localhost dev1` to your hosts file :
1. MAC /private/etc/hosts;
2. LINUX /etc/hosts;
3. WINDOWS \Windows\system32\private\etc\hosts;
4. WINDOWS 10 and 7 **C:\Windows\System32\drivers\etc\hosts**;
From now on, everytime you type dev1 on this computer, your computer will use the loopback interface to connect to dev1. It will understand that you want to work on localhost (127.0.0.1).
### 3. Access localhost from an other computer
We need to tell the other computers how they could find localhost eg on oralin76.
3a Get the IP address of the computer hosting the website:
In the terminal (CLI),
1. on LINUX (oralin76) and MAC type **ifconfig |grep inet**
2. on WINDOWS type `ipconfig`
Let's assume the IP address of oralin76 is 192.168.5.13 .
3b Edit hosts file on oralin76 computer you are trying to access the website from :
Trick is to use IP address of oralin76 (computer we are trying to access/talk to):
192.168.5.13 oralin76.sspc2
You can now go into your browser and type http://oralin76.sspc2 (symfony.local) to beautifully see your website on different computers! Note that you can apply the same strategy if you are a OSX user to test your website on Internet Explorer via Virtual Box (if you don't want to use a Windows computer). This is beautifully explained in Crafting Your Windows / IE Test Environment on OSX
http://www.studiobanks.com/blog/post/279/crafting-your-windows-ie-test-environment-on-osx-106.
You can also access your localhost from mobile devices, see http://egalo.com/2012/05/29/testing-mac-web-site-using-local-hostname-on-mobile-device/

## 7\. Access Linux share dir from Windows with WinSCP FTP
How we can see RHEL type linux 64 bit share in Windows 10 64 bit Network folder ?
I can in Linux file explorer ctrl+c, v files on win10 to/from Linux.
With WinSCP FTP I can sync website tree.
### WinSCP FTP website tree synchronization
1. chown -R someuser:somegroup /your/folder/here/* (Recursive mode only works on directories, not files.)
This will apply chown to all files and all subdirectories and sub-subdirectories of the specified folder. Use with care.
**sudo chown -R oracle:oracle /opt/lampp/htdocs/fwphp/** On Debian Linux : var/www/html/fwphp
**sudo chmod 755 /opt/lampp/htdocs/fwphp -R**
2. **WinSCP FTP -> "New session" icon -> button "Edit" -> button "Advanced"**
assign SFTP value : /usr/libexec/openssh/sftp-server
assign Shell value : sudo su -
### Synchronization using PHP interpreter
See http://dev1:8083/fwphp/glomodul/mkd/?edit=01/001_config_ssl_tls/ftp.txt
> **/opt/lampp/htdocs** /u01/userhome/oracle
> To create or delete file you need have a write permissions to the directory;
> To change file or directory permissions you need to be its owner;
> To change file modification time you need to be its owner (note that by default WinSCP updates file modification time when uploading).

Updating / installing... 1:oracle-xe-11.2.0-1.0
Executing post-install steps... You must run '/etc/init.d/oracle-xe configure' as the root user to configure the database.
### /etc/init.d/oracle-xe configure
This will configure on-boot properties of 11g XE. The following questions will determine whether DB should be starting upon system boot, ports it will use, passwords that will be used for DB accounts.
Press ENTER to accept the defaults. Ctrl-C will abort.
Specify the HTTP port that will be used for Oracle Application Express \[8080\]:**8085**
Specify a port that will be used for the database listener \[**1521**\]:
Specify a password to be used for database accounts - same password will be used for SYS and SYSTEM. Oracle recommends the use of different passwords for each database account. This can be done after initial configuration:
Do you want Oracle Database 11g Express Edition to be started on boot (y/n) \[y\]:**y**
Starting Oracle Net Listener...Done Configuring database...Done Starting Oracle Database 11g Express Edition instance...Done
**Installation completed successfully.**
We need to **re-boot Linux** so that Linux menu items in App -> Other are visible.
NOTE : from this point on **you can stop being root** (although you may need to sudo occasionally).
To confirm that your database is up and running :
conn system/pwd
select sysdate from dual
/
### Setting (sorting out) DB XE Environment Variables
Log on with root permissions is not needed.
do not exit (from root user)
DB XE provides a script that sets environment variables :
**cd /u01/app/oracle/product/11.2.0/xe/bin**
[ora@oralin76 bin]$ cat /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/xe
export ORACLE_SID=XE
export NLS_LANG=`$ORACLE_HOME/bin/nls_lang.sh`
export PATH=$ORACLE_HOME/bin:$PATH
No need : `gedit ./oracle_env.sh`
sudo gedit /u01/app/oracle/product/11.2.0/xe/bin/nls_lang.sh
`At end : NLS_LANG=${nlslang}.${charset} should be : NLS_LANG="${nlslang}.${charset}"`
**. ./oracle_env.sh**
```
echo $ORACLE_HOME
echo $ORACLE_SID
echo $NLS_LANG
echo $PATH
[ora@oralin76 bin]$ echo $ORACLE_HOME
/u01/app/oracle/product/11.2.0/xe
[ora@oralin76 bin]$ echo $ORACLE_SID
XE
[ora@oralin76 bin]$ echo $NLS_LANG
AMERICAN_AMERICA.AL32UTF8
[ora@oralin76 bin]$ echo $PATH
/u01/app/oracle/product/11.2.0/xe/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/var/lib/snapd/snap/bin:/home/ora/.local/bin:/home/ora/bin
```
Oracle bin directory is now at the start of $PATH.
We need to ensure that these **environment variables are set for all sessions** :
sudo cp /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh /etc/profile.d/
To check this, you can start a new terminal session and echo the environment variables to make sure they have been set.
Getting the Menu Items to Work - make sure that the oracle user, as well as your own user, is a member of the dba group :
sudo usermod -a -G dba oracle
sudo usermod -a -G dba ss
sudo grep dba /etc/group
dba:x:1001:oracle
### Enabling "Getting Started" Desktop Icon to open the DB Home Page of APEX app
**Right-click icon and select Properties**.
In the Permissions Tab check the box to "Allow executing file as program".
Icon has transformed into Oracle beehive and is now called "Get Started With 11g XE".
Installation on Red Hat system is reasonably painless when compared with doing the same thing on a Debian system.
run it :
`./oracle/env.sh`
cd /etc/skel
ls -la | grep .bash\_profile
Edit login or profile files so that these environment variables are set each time you log in or open a new shell :
`gedit .bash\profile`
enter the following line at end ` /etc/skel/.bash\profile` :
` /u01/app/oracle/product/11.2.0/xe/bin/oracle\_env.sh`
Starting Oracle Database XE
To start the database manually, run this command as root user:
** /etc/init.d/oracle-xe start** or **/etc/init.d/oracle-xe stop
or :
**After you have installed Oracle Database XE, DB is up and running and you can start it if it is currently stopped:
Main menu (on Gnome)->Oracle Database 11g Express Edition
or Applications->Other menu (on KDE),
and then click Start Database or Run SQL Command Line or...
Connect to the database using the user name SYSTEM, and supply the password that you created during configuration.
conn sys/ss141 as SYSDBA (system can not)

## Oracle 11g XE on RHEL7
December 3, 2014 [https://shi2wei3.github.io/posts/2014-12-03-oracle-11g-xe-on-rhel7.html](https://shi2wei3.github.io/posts/2014-12-03-oracle-11g-xe-on-rhel7.html)
[database](https://shi2wei3.github.io/tags/database.html)
The prerequisite is i assume you already got a RHEL7 installed with GNOME3
## Install oracle database 11gXE
it needs swap volume at least specify space 2 x memory (12 GB)
unzip oracle-xe-11.2.0-1.0.x86_64.rpm.zip
cd Disk1
sudo rpm -ivh oracle-xe-11.2.0-1.0.x86_64.rpm
## Install sqlplus
su -
cd **/home/ssoralin73**
chmod 776 oracle-xe-11.2.0-1.0.x86\_64.rpm.zip
unzip instantclient-basic-linux.x64-12.2.0.1.0.zip
unzip instantclient-sdk-linux.x64-12.2.0.1.0.zip
unzip instantclient-sqlplus-linux.x64-12.2.0.1.0.zip
cd instantclient\_12\_2
ls -l
ln -s libclntsh.so.12.1 libclntsh.so
ln -s libocci.so.12.1 libocci.so
To avoid error ee to see libsqlplus.so :
./sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory
**export LD\_LIBRARY\_PATH=$(pwd)**
./sqlplus sys/ss141@localhost/XE as SYSDBA (system can not)
alter user hr account unlock;
alter user hr identified by hr;
grant CONNECT,DBA,RESOURCE to hr IDENTIFIED BY hr;
or grant create table to hr; ...
ALTER USER ANONYMOUS ACCOUNT UNLOCK;
\# cd **/home/ssoralin73**/instantclient\_12\_2
\# ./sqlplus hr/hr@localhost/XE
### Alternative: rpm instantclient installation
put all three rpm in some tmp dir and :
ls \*rpm
rpm -i \*rpm
ls /usr/lib/oracle/12.1/client64/lib
ls /usr/lib/oracle/12.1/client64/bin - here is sqlplus dir
export LD\_LIBRARY\_PATH=/usr/lib/oracle/12.1/client64/lib
/usr/lib/oracle/12.1/client64/bin/sqlplus hr/hr@localhost/XE
or :
sudo rpm -ivh oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm
sudo rpm -ivh oracle-instantclient12.1-sqlplus-12.1.0.2.0-1.x86_64.rpm
If you got the error below, you need to add library path manually: sqlplus64: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/oracle/12.1/client64/lib/
#### which sqlplus
```
/usr/bin/which: no sqlplus in (/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)
