Configuring WebLogic and OHS as a Service on Linux

Complete the following steps to install WebLogic and Oracle HTTPS Server (OHS) as a service on a Linux 64-bit operating system.

Set WL_HOME as system environment variable or modify it in <unifier_home>/weblogic/setenv.sh. WL_HOME is the root directory of the WebLogic installation. For detailed instructions, refer to Creating a WebLogic Domain for Unifier on Windows to create the Domain Home for weblogic.
For example: C:\Oracle\Middleware\wlserver_11\server
Set the environment variables for Unifier. For detailed instructions, refer to Changing Unifier Configurator Settings on Windows.
For WebLogic installed in production mode, create boot.properties at $DOMAIN_HOME/servers/<server_name>/security.
Ensure all variables are set for a ROOT_USER.
Log into Linux as a ROOT_USER.
In the <unifier_home>/weblogic/unifier, modify values for the following parameters:
- OHS_INSTANCE_HOME: The home directory of OHS.
- UNIFIER_HOME: The home directory of Primavera Unifier.
- OHS_USER: User who can start OHS. Alternatively, locate the user in the httpd.conf file.
- WL_USER: User who can start WebLogic.
  Note: Change the command to start weblogic in accordance to the user privilege on the system.
Ensure that when the server is restarted the Xvfb process is also started with the same DISPLAY value as follows for the ROOT_USER:
1. Install Xvfb
  yum install Xvfb
2. start Xvfb
  locate Xvfb (where Xvfb is installed)
  
  /usr/bin/Xvfb :99 -screen 0 1x1x8 &
3. Edit the unifier file to add: export DISPLAY=:99
Copy the unifier script into the /etc/rc.d/init.d folder
To make the file executable, run the command: chmod 755 unifier
To add the service at system reboot, run the command: chkconfig --add unifier
To start the unifier service from the console, run the command: service unifier start
