Configuring PingAccess to run as a Linux systemv service

Configure PingAccess to run as a Linux systemv service, causing it to start automatically when Linux starts.

About this task

The service script will only start if <JAVA_HOME> and <PA_HOME> are set and the PingAccess license file is found.

Copy the PingAccess script file from <PA_HOME>/sbin/linux/pingaccess to /etc/init.d.
Optional: Create a new user to run PingAccess.
Create the folder /var/run/pingaccess.

Ensure that the user who will run the service has read and write permissions to the folder.
Edit the script file /etc/init.d/pingaccess and set the values of following variables at the beginning of the script:
- export <JAVA_HOME>=: Specify the Java install folder.
- export <PA_HOME>= : Specify the PingAccess install folder.
- export USER=: (Optional) Specify username to run the service or leave empty for the default.
To register the service, from the /etc/init.d folder, run:
```
chkconfig --add pingaccess
```
To make the service script executable, run:
```
chmod +x pingaccess
```

After registering, you can use the service command to control the PingAccess service. The available commands are:

start: Start the PingAccess service.
stop: Stop the PingAccess service.
restart: Restart the PingAccess service.
status: Show the status of the PingAccess service and the service process identifier (PID).

The command service pingaccess status displays the current status of the running PingAccess service.
