To launch a new Slave-DB server that will start replicating with the Master-DB.
Table of Contents
You should only launch a Slave-DB if you already have an operational Master-DB and a completed backup (snapshots). When the Slave-DB becomes operational, it will automatically start replicating data from the Master-DB. Since the Slave-DB will typically be initialized with the most recent backup of the Master-DB, the time required for the Slave-DB to become in-sync with the Master-DB should be minimized.
If you have a running Master-DB instance, you can launch a new Slave-DB and have it automatically start replicating with the Master-DB by setting the INIT_SLAVE_AT_BOOT input variable set to "True" at launch time. After a slave has been initialized, its contents will be in-sync with the master and the replication will be active.
Note: If you are launching a Slave-DB server for the first time with RightScale's premium MySQL ServerTemplates, it's recommended that you follow the appropriate "stripe" MySQL Database Setups tutorials.
If you are launching a master and slave for the first time, you should follow the MySQL-EBS v2 Database Setup tutorial.
The Events pane will highlight the progress of the operation. Click on the name of an action in the pane to view a detailed output of the action that can be used to troubleshoot the cause of a failure, if necessary.
IMPORTANT! When you are done, make sure your Servers are named appropriately! Make sure you know which Server is your master and which one is your slave.
