It looks like you are starting the first node of the cluster, the first node should not look for any other node of the cluster but it should perform what is called 'bootstrap', this can be achieved in a couple of ways(one is the way Nirbhay mentioned), for more complete reference on this please refer to: https://mariadb.com/blog/mariadb-galera-cluster-quirk-bootstrapping
Hi, Thank you for your reply. I got partial success, but still not able to initialize the cluster:
[dbadmin@mariadb-N1 ~]$ sudo service mysql start --wsrep-new-cluster --wsrep_cluster_address='' Starting mysql (via systemctl): [ OK ] [dbadmin@mariadb-N1 ~]$ mysql -u root -p --execute="SHOW GLOBAL STATUS WHERE Variable_name IN ('wsrep_ready', 'wsrep_cluster_size', 'wsrep_cluster_status', 'wsrep_connected');" Enter password: +----------------------+--------------+ | Variable_name | Value | +----------------------+--------------+ | wsrep_cluster_size | 0 | | wsrep_cluster_status | Disconnected | | wsrep_connected | OFF | | wsrep_ready | OFF | +----------------------+--------------+ [dbadmin@mariadb-N1 ~]$ mysql -u root -p --execute="SET GLOBAL wsrep_cluster_address='gcomm://172.20.1.56,172.20.1.57,172.20.1.58';" Enter password: ERROR 2013 (HY000) at line 1: Lost connection to MySQL server during query [dbadmin@mariadb-N1 ~]$This could be due to the following bug: https://jira.mariadb.org/browse/MDEV-10186. So, alternatively, you could set empty wsrep_cluster_address in config file along with other mandatory options and later update it to add more IPs once the cluster is up.
