There can be a time when we want to shut down our entire cluster; maybe for a move to a different facility, or because we are replacing it completely. Whatever the reason, this recipe outlines the preferred way to do so.
Create MariaDB Galera Cluster as described in the Installing MariaDB Galera Cluster recipe earlier in this chapter.
Ensure that any applications using the cluster are shut down.
On
db03
, run the following command to check whether the node is up to date:mysql -e "SHOW STATUS LIKE 'wsrep_local_state_comment'"
If the value is synced, run the following command to shut down the node:
sudo service mysql shutdown
On
db02
anddb01
, repeat the same steps, first ondb02
, and then ondb01
.
