[SOLVED] mariadb installing on ubuntu mate cluster

mariadb installing on ubuntu mate cluster

I'm trying to install mariadb on a cluster (ubuntu mate 16.04) with 3 nodes. I did all the things that this link said, but after running :

sudo service mysql start —wsrep-new-cluster

I get this error:

Job for mysql.service failed because the control process exited with 
error code. See "systemctl status mysql.service" and "journalctl -xe" 
for details.

I checked status, but I couldn't understand the problem:

mysql.service - LSB: Start and stop the mysql database server daemon

any help would be appreciated.

P.S. the nodes are:

compute-00 11.0.0.1 (master)

compute-01 11.0.0.2

compute-02 11.0.0.3
