1、嘗試重啟mysql數(shù)據(jù)庫時(shí)報(bào)錯(cuò)
[root@galera01 ~]# /etc/init.d/mysqld start  --wsrep-new-cluster
MySQL Daemon failed to start.
Starting mysqld:  [FAILED]

2、查看啟動(dòng)報(bào)錯(cuò)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(dòng)其他節(jié)點(diǎn)，相同報(bào)錯(cuò)
從錯(cuò)誤日志提示報(bào)錯(cuò)提示，當(dāng)前節(jié)點(diǎn)不是集群中最后離開的節(jié)點(diǎn)，也就是說當(dāng)前節(jié)點(diǎn)可能未能包含所有的更新。
如果強(qiáng)制啟動(dòng)當(dāng)前節(jié)點(diǎn)，需要修改grastate.dat文件將safe_to_bootstrap的值置為1。
嘗試先啟動(dòng)其他節(jié)點(diǎn)，相同報(bào)錯(cuò)。

4、修改grastate.dat文件
該文件主要描述GALERA保持的狀態(tài)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(dòng)

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