mysql主从问题处理记录
Slave服务器宕机,导致Slave服务器启动后 show slave status \G 后提示错误
Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: 'binlog truncated in the middle of event'
解决:
Master: show master status \G #记录 Master 以下信息
File: mysql-MasterSlave.000006
Position: 174367
Slave: slave stop;
reset slave;
change master to master_host='192.168.1.126',master_user='USER',master_password='PW',master_log_file='mysql-MasterSlave.000006',master_log_pos=174367;
提示:从 Mysql 5.5 开始 Mysql 加入半同步复制,取消了 load data from master 之类的用法,MySQL Slave/Master实例在异常终止恢复之后,MySQL Slave可以处理未完成的或丢弃Master写如log失败数据,从而重新从master上获取源数据,同样,Master 实例重启不会使 Slave 丢失数据。
