OpsCenter 4.0 User Guide

Using custom start/stop scripts for DataStax Enterprise and Cassandra

OpsCenter allows users to start and stop the DataStax Enterprise/Cassandra process on each node in a visual way. The agent will attempt to automatically determine the best way to do this, but cannot not 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).


  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
