To have join the cluster, you need to edit /opt/kaltura/app/configurations/db.ini on each relevant node.
You will see:
sphinx1.adapter = mysql
sphinx1.connection.dsn = “mysql:host=somehost1;port=9312;”
sphinx2.adapter = mysql
sphinx2.connection.dsn = “mysql:host=somehost2;port=9312;”
sphinx1.connection.dsn should reflect the first node, sphinx2.connection.dsn, the second one.
You can add more if you want, in which case, you need to add:
datasources.2 = sphinx3
and:
sphinx3.adapter = mysql
sphinx3.connection.dsn = “mysql:host=somehost3;port=9312;”
