2.4.2.4 Starting Multi-Source Replication Slaves

Once you have added all of the channels you want to use as replication masters, use a START SLAVE thread_types statement to start replication. When you have enabled multiple channels on a slave, you can choose to either start all channels, or select a specific channel to start.

  • To start all currently configured replication channels:

    START SLAVE thread_types;
  • To start only a named channel, use a FOR CHANNEL channel clause:

    START SLAVE thread_types FOR CHANNEL channel;

Use the thread_types option to choose specific threads you want the above statements to start on the slave. See START SLAVE Syntax for more information.
