1.日志报错如下

2019-03-04T10:10:55.921199Z 0 [ERROR] WSREP: failed to open gcomm backend connection: 110: failed to reach primary view (pc.wait_pri

2019-03-04T10:10:55.921347Z 0 [ERROR] Aborting

2.启动报错如下

[root@DSJPT-23 data]#  /etc/init.d/mysql start
Starting MySQL (Percona XtraDB Cluster).......................................The server quit without updating PID file (/data/mysql/mysqld.pid).                                              [FAILED]
MySQL (Percona XtraDB Cluster) server startup failed!      [FAILED]

2.上网查看有如下：

（1）selinux

（2）防火墙

（3）rm -rf /var/lock/subsys/mysql  并且 rm -rf galera.cache grastate.dat

均不行。

最后发现是wsrep_cluster_name三个节点不一样，修改后ok。
