Customize scripts for starting and stopping DataStax Enterprise

OpsCenter allows starting and stopping the DataStax Enterprise process on each node in a visual manner. Customize the startup or shutdown of a node using the provided example scripts.

OpsCenter allows starting and stopping the DataStax Enterprise process on each node in a visual manner. The agent attempts to automatically determine the best way to do this but cannot do so in all cases. You can customize the startup or shutdown of a node using the start-cassandra and stop-cassandra scripts located in /usr/share/datastax-agent/bin (package installs) or install_location/bin (tarball installs).

Procedure

  1. Rename the example script in /usr/share/datastax-agent/bin (package installs) or install_location/bin (tarball installs) to remove the .example extension.
    • start-cassandra.example: example startup script
    • stop-cassandra.example: example shutdown script
    cd /usr/share/datastax-agent/bin
$ mv start-cassandra.example start-cassandra
  2. Edit the script to customize the behavior. The script should return an exit code of 0 when successful, and a non-zero value if it fails.
  3. Make the script executable. 
    chmod 755 start-cassandra
