MariaDB Galera Quicktips


Set mysql server to auto start on all nodes.

Only when all the nodes are down run on main node.

sudo service mysql start --wsrep-new-cluster

Run the following on member nodes.

sudo service mysql start 

Join nodes to cluster by using command, with IP of one of the cluster nodes.

sudo service mysql start –wsrep_cluster_address=gcomm://ip_address

Check cluster size

mysql -u root -p -e ‘SELECT VARIABLE_VALUE as “cluster size” FROM INFORMATION_SCHEMA.GLOBAL_STATUS WHERE VARIABLE_NAME=”wsrep_cluster_size”‘

Double check configuration files

sudo nano /etc/mysql/conf.d/galera.cnf
sudo nano /etc/mysql/conf.d/my.cnf
