[root@percona01 ~]# cat /etc/my.cnf
[mysqld]

Path to Galera library

wsrep_provider=/usr/lib64/libgalera_smm.so

Cluster connection URL

wsrep_cluster_address=192.168.11.60

In order for Galera to work correctly binlog format should be ROW

binlog_format=ROW

MyISAM storage engine has only experimental support

default_storage_engine=InnoDB

This changes how |InnoDB| autoincrement locks are managed and is a requirement for Galera

innodb_autoinc_lock_mode=2

Where could be the problem?

Also tryed with wsrep_cluster_address=gcomm://192.168.11.60 in my.cnf

Yes, the wsrep_cluster_address must start with gcomm://.
What is the 192.168.11.60 here? Is the node you are trying to start a first one?
Also, always the answer why starting mysqld failed is in the error log :slight_smile:
