Hi @vadimtk

added the wsrep\_cluster\_address = gcomm://192.168.0.1,192.168.0.2,192.168.0.3 in all the nodes 1,2,3.

After bootstrapped the first node ,Started the mysql service at node 2 ,facing the below error.

Attaching the error log file for your reference.

[node 2 error.log](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/1X/a936711278b2a3cfe43dfc89b544b1fa9ad727f5.log)

Note : I have changed the variable from ON to pxc-encrypt-cluster-traffic=OFF in all the config files.

root@pxc-2:~# service mysql start

Job for mysql.service failed because the control process exited with error code.

See “systemctl status mysql.service” and “journalctl -xe” for details.
