|
* - check status using Maxadmin 'show servers' and 'show monitor "MySQL Monitor"'
|
|
* - Set nodes 0 and 1 into read-only mode
|
|
* - repeat status check
|
|
* - Configure nodes 1 and 2 (server2 and server3) into a master-master pair, make node 0 a slave of node 1 and node 3 a slave of node 2
|
|
* - repeat status check
|
|
* - Set node 1 into read-only mode
|
|
* - repeat status check
|
|
* - Create two distinct groups (server1 and server2 are masters for eache others and same for server3 and server4)
|
|
* - repeat status check
|
|
* - Set nodes 1 and 3 (server2 and server4) into read-only mode
