I’m testing the Galera cluster.

The environment is Centos 7.2. DB is MySQL 5.6.

The success message was confirmed using the following instructions.

/etc/init.d/mysql start --wsrep-new-cluster

Starting MySQL… SUCCESS!

But if you check the cluster size, it says 0.

mysql -uroot -p -e “SHOW STATUS LIKE ‘wsrep_cluster_size’”

Enter password: ±-------------------±------+ | Variable_name | Value | ±-------------------±------+ | wsrep_cluster_size | 0 | ±-------------------±------+

The cnf file of the initial node I set is as follows.

/etc/my.cnf.d/galera.cnf

---

[mysqld] binlog_format=ROW default-storage-engine=innodb innodb_autoinc_lock_mode=2 bind-address=0.0.0.0

Galera Provider Configuration

wsrep_on=ON wsrep_provider=/usr/lib64/galera-3/libgalera_smm.so
