Question

I have three server that I want to Install Galera clustering on them, I followed this link to install and config it. but when I want to start the first server I got this error :

root@node107:/home/debian# service mysql start --wsrep-new-clusterping 
Job for mysql.service failed. See 'systemctl status mysql.service' and 'journalctl -xn' for details.

and :

root@node107:/home/debian# journalctl -xn

these are configuration file for the three servers :

vim /etc/mysql/conf.d/cluster.cnf

Server1 :

# Galera Node Configuration
wsrep_node_address="192.168.120.117"
wsrep_node_name="node117"

I don't understand what I have missed. what should I do?

Answer 1

We should start the first node without below parameter in my.cnf : wsrep_cluster_address="gcomm://192.168.120.107,192.168.120.111,192.168.120.117"

Then start the other nodes normally :

/etc/init.d/mysql start

The first node should start normally like the others.

Answer 2

Please bootstrap the first node with below option

service mysql start --wsrep-new-cluster 

Make sure you have the settings below in all config files:

wsrep_cluster_address="gcomm://192.168.120.107,192.168.120.111,192.168.120.117"

Then start the other nodes using service mysql start

Both nodes will sync with bootstrap node.
