3.3.4. Configuring Startup on Boot

Note

The procedures in this section are designed for the Multisite/Multimaster topology ONLY. Do NOT use these procedures for Composite Multimaster Clustering uing v6 onwards.

For version 6.x Composite Multimaster Clustering Clustering, please refer to Deploying Composite Multimaster Clustering.

Because there are two different Continuent services running, each must be individually configured to startup on boot:

  • For the Tungsten Clustering service, use Section 4.3, “Configuring Startup on Boot”.

  • For the Tungsten Replicator service, a custom startup script must be created, otherwise the replicator will be unable to start as it has been configured in a different directory.

    1. Create a link from the Tungsten Replicator service startup script in the operating system startup directory (/etc/init.d):

      shell> sudo ln -s /opt/replicator/tungsten/tungsten-replicator/bin/replicator /etc/init.d/mmreplicator
    2. Modify the APP_NAME variable within the startup script (/etc/init.d/mmreplicator) to mmreplicator:

      APP_NAME="mmreplicator"
    3. Update the operating system startup configuration to use the updated script.

      On Debian/Ubuntu:

      shell> sudo update-rc.d mmreplicator defaults

      On RedHat/CentOS:

      shell> sudo checkconfig --add mmreplicator
