relay.index' not found

主備搭建時，備庫上執行如下語句報錯：

(root@localhost:mysql.sock)[(none)]>change master to master_host='192.168.0.57',
    -> master_user='rep1',
    -> master_password='wqq',
    -> master_log_file='binlog.000001',
    -> master_log_pos=0;
ERROR 2006 (HY000): MySQL server has gone away
No connection. Trying to reconnect...
Connection id:    2
Current database: *** NONE ***

ERROR 29 (HY000): File '/data/mysql/relay_log/relay.index' not found (Errcode: 2 - No such file or directory)

解決辦法：

建立相應目錄及relay-log.index

[root@upright etc]# cd /data/mysql/

[root@upright mysql]# mkdir relay_log

[root@upright mysql]# cd relay_log/

[root@upright relay_log]# vi relay-log.index

[root@upright relay_log]# cd ..

[root@upright mysql]# chown mysql:mysql  relay_log -R
