1. Installing Oracle WebLogic
In my case, the installation will be done on CentOS 5.5 (32-bit).
First, create a user who will own the software and on whose behalf all will be triggered by the good old
tradition, this is oracle :) . Just create a folder where all will be put. Following Oracle Flexible
Architecture (OFA), it will be / u01/oracle /……..
root@oragrid: ~# cat /etc/group | grep 'oinstall|dba'
root@oragrid: ~# /usr/sbin/groupaddoinstall
root@oragrid: ~# /usr/sbin/groupadddba
root@oragrid: ~# id oracle
root@oragrid: ~# /usr/sbin/useradd -g oinstall -G dba oracle
root@oragrid: ~# passwd oracle
Changing password for user oracle.
New UNIX password:

2. Retype new UNIX password:
passwd: all authentication tokens updated successfully.
root@oragrid: ~# id nobody
root@oragrid: ~# /usr/sbin/useradd nobody
root@oragrid: ~# mkdir -p /u01/oracle
root@oragrid: ~# chown -R oracle:oinstall /u01/oracle
As I put on a remote server, you have to variable DISPLAY, to point to the
local machine, and allow the local server x11 incoming connections from the
server.
root@oragrid: ~# su – oracle
oracle@oragrid: ~> export DISPLAY=172.30.9.25:0.0
oracle@oragrid: ~> cd GridControl/
oracle@oragrid: ~/GridControl> ./runInstaller
Run the installer.

3. Select the directory in which all the software will be located.
Then

4. Choose the type of installation. As I do not need a set of plug-ins for Eclipse, I
chose a custom installation.
Select the JDK, what we want to deliver.

5. Specify the directory in which to install weblogic server, usually a subdirectory in
the Middleware HOME.
A brief overview of what will be installed.

6. So the process has begun.

7. Choosing «Getting started with WebLogic Server». And here we have opened a window
like this.

8. Create a new domain Weblogic.

9. Write the name of our domain.
Configure the administrator of our server. The default is weblogic.

10. Then you can further customize our Administration Server, Managed Servers, Clusters,
and Machines. I made 2 test server.

13. We tie our servers to your local machine.

14. Domain creation and brief information about where the domain is located and how to
reach out to the Administration Server.
The installation and initial setup of Oracle Weblogic Server is completed.
