1、嘗試重啟 mysql 數據庫時報錯
[root@galera01 ~]# /etc/init.d/mysqld start –wsrep-new-cluster
MySQL Daemon failed to start.
Starting mysqld: [FAILED]

2、查看啟動報錯日志
2017-07-24T02:45:41.972508Z 0 [ERROR] WSREP: It may not be safe to bootstrap the cluster from this node. It was not the last one to leave the cluster and may not contain all the
updates. To force cluster bootstrap with this node, edit the grastate.dat file manually and set safe_to_bootstrap to 1 .
2017-07-24T02:45:41.972511Z 0 [ERROR] WSREP: wsrep::connect(gcomm://192.168.56.111,192.168.56.112,192.168.56.113) failed: 7
2017-07-24T02:45:41.972513Z 0 [ERROR] Aborting

2017-07-24T02:45:41.972516Z 0 [Note] Giving 0 client threads a chance to die gracefully
2017-07-24T02:45:41.972519Z 0 [Note] WSREP: Service disconnected.
2017-07-24T02:45:42.972895Z 0 [Note] WSREP: Some threads may fail to exit.
2017-07-24T02:45:42.972937Z 0 [Note] Binlog end
2017-07-24T02:45:42.973014Z 0 [Note] /usr/sbin/mysqld: Shutdown complete

3、嘗試先啟動其他節點，相同報錯
從錯誤日志提示報錯提示，當前節點不是集群中最后離開的節點，也就是說當前節點可能未能包含所有的更新。
如果強制啟動當前節點，需要修改 grastate.dat 文件將 safe_to_bootstrap 的值置為 1。
嘗試先啟動其他節點，相同報錯。

4、修改 grastate.dat 文件
該文件主要描述 GALERA 保持的狀態信息，按指引修改 safe_to_bootstrap 的值置為 1。
# cat grastate.dat
# GALERA saved state
version: 2.1
uuid: df4a1da6-701a-11e7-87fe-e6c3a440d1ec
seqno: -1
safe_to_bootstrap: 1 — 由原來的 0 修改為 1 再次啟動

# /etc/init.d/mysqld start –wsrep-new-cluster
Starting mysqld: [ OK ]
5、mysql 集群啟動成功
