When investigating problems with starting, remember to always check the error log. The systemd status does not provide the details. The error log will be likely in /var/log/mysqld.log or similar or maybe logging to syslog. Best to specify the error log file explicitly with log\_error setting. Check also what configuration is under /etc/my.cnf.d/ Btw, I can see wrong used variable: ```auto wsrep_sst_auth="11111111e" ``` It should be in a form of ```auto wsrep_sst_auth="user:pass" ``` [URL][Index of wsrep system variables - Percona XtraDB Cluster](https://www.percona.com/doc/percona-xtradb-cluster/5.7/wsrep-system-index.html#wsrep_sst_auth%5B/URL%5D)
