1.Can't start server: Bind on TCP/IP port: Address already in use

2017-12-07T10:25:56.216309+08:00 0 [ERROR] Can't start server: Bind on TCP/IP port: Address already in use

2017-12-07T10:25:56.216324+08:00 0 [ERROR] Do you already have another mysqld server running on port: 22308 ?

2017-12-07T10:25:56.216340+08:00 0 [ERROR] Aborting

故障处理

主要是改参数设置有问题，参数为

wsrep_node_address=192.168.192.65:22308

正确设置为：

wsrep_node_address=192.168.192.65

2.It may not be safe to bootstrap the cluster from this node

2017-12-15T13:11:30.237139+08:00 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 .

2017-12-15T13:11:30.237148+08:00 0 [ERROR] WSREP: Provider/Node (gcomm://10.66.192.65:4567,10.66.192.66:4567,10.66.192.67:4567) failed to establish connection with cluster (reason: 7)

2017-12-15T13:11:30.237158+08:00 0 [ERROR] Aborting

故障处理

集群本身无问题，只是非正常关闭。

修改第一个启动节点的grastate.dat文件，将

# GALERA saved state

version: 2.1

uuid:      8ed447b7-dafa-11e7-8071-a6ba78498531

seqno:     -1

safe_to_bootstrap:   0   改为 1

然后可以直接启动

3.Error in Log_event::read_log_event(): 'read error'

2017-12-15T15:16:35.195586+08:00 0 [ERROR] Error in Log_event::read_log_event(): 'read error', data_len: 11730978, event_type: 51

2017-12-15T15:16:35.195606+08:00 0 [Warning] Error reading GTIDs from binary log: -1

故障处理

binlog参数设置过长，导致无法正确生成binlog和正常的读取

log-bin                         =/data/mysql/db_test1/binlog/192.168.10.128_test1_bin

log-bin-index=/data/mysql/db_test1/binlog/192.168.10.128_test1_bin.index

-rw-r--r-- 1 mysql mysql 177 Dec 15 15:19 192.168.10

-rw-r--r-- 1 mysql mysql  40 Dec 15 15:17 192.168.10.128_test1_bin.index
