重启了一下从库，忘记先stop slave ，直接mysqladmin shutdown关闭实例，结果起不来了mysql

mysql> start slave;
ERROR 1872 (HY000): Slave failed to initialize relay log info structure from the repositorysql

这个错误就是relay log有问题，但我看本身的配置中有配置relay_log参数，但为何从库启动会在此处出问题呢spa

从新开启同步，先记下当前从库同步的位置code

mysql> show slave status\G;
*************************** 1. row ***************************
               Slave_IO_State: 
                  Master_Host: 10.*.*.*
                  Master_User: db_slave
                  Master_Port: 3301
                Connect_Retry: 60
              Master_Log_File: mysql-bin.013463
          Read_Master_Log_Pos: 247058609

reset master;
reset slave all;blog

mysql> CHANGE MASTER TO
-> MASTER_HOST='10.***',
-> MASTER_USER='db_slave',
-> MASTER_PASSWORD='***********',
-> MASTER_PORT=3301,
-> MASTER_LOG_FILE='mysql-bin.013463',
-> MASTER_LOG_POS=247058609,
-> MASTER_CONNECT_RETRY=10;
ERROR 29 (HY000): File '/data/mysql_3301/var/mysql-relay-bin.000001' not found (Errcode: 2 - No such file or directory)同步

结果仍是报错，仍是关于relay log的，而后it

修改配置文件，新建一个目录，从新为relay log指定一个目录，再也不使用原来的目录ast

relay_log = /data/mysql_3301/log/mysql-relay-binclass

再次CHANGE MASTER TO……，start slave，此次从库成功启动了配置
