Bootup customization scripts in NetScaler BLX
NetScaler BLX provides a mechanism for bootup customization through the scripts that run before and after BLX starts. Create the bootup scripts named nsbefore.sh and nsafter.sh to tailor the BLX environment to your specific needs. By using these bootup customization scripts, you can automate tasks, enforce configuration standards, and optimize the BLX environment for your specific use case.
-
nsbefore.sh: - This script runs before BLX starts. Typical use cases include:
-
Setting environment variables required by any dependent services.
-
Modifying configuration files to apply custom settings.
-
Starting prerequisite services that BLX relies on.
-
-
nsafter.sh: - This script runs after BLX has fully initialized. Typical use cases include:
-
Performing system health checks to ensure BLX is running correctly.
-
Managing log files, such as log rotation or archiving.
-
Launching more applications or services that are dependent on the BLX instance.
-
Configuring the bootup scripts
-
Create the
nsbefore.shandnsafter.shscripts in the/nsconfig/directory only for BLX to recognize and run them during bootup. -
Ensure that the scripts have the necessary permissions to run (for example,
chmod +x nsbefore.sh). -
Thoroughly test any changes made within these scripts in a controlled environment before deploying them to production.
