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
故障處理
主要是改參數設置有問題，參數爲
wsrep_node_address=192.168.192.65:22308
正確設置爲：
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
故障處理
集羣本身無問題，只是非正常關閉。
修改第一個啓動節點的grastate.dat文件，將
# GALERA saved state
version: 2.1
uuid: 8ed447b7-dafa-11e7-8071-a6ba78498531
seqno: -1
safe_to_bootstrap: 0 改爲 1
然後可以直接啓動
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
故障處理
binlog參數設置過長，導致無法正確生成binlog和正常的讀取
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
