兴高采烈的登陆机器测master HA，结果mysql竟然挂了。
那就重启吧

[root@testdb3 mysql]# mysql -uroot p ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) |
我裤子都脱了，结果他给我看这个：

[root@testdb3 mysql]# service mysql start Starting MySQL (Percona Server).The server quit without updating PID file (/var/run/mysqld/mysqld.pid).[FAILED] |
找了半天找到日志目录：/app/mysql/mysqld.log

查找./mysql-bin.000001，发现这个文件不在mysql lib目录（/var/lib/mysql）下面。

[root@testdb3 mysql]# pwd /var/lib/mysql [root@testdb3 mysql]# ls mysql-relay-bin.202753 mysql-relay-bin.202755 RPM_UPGRADE_HISTORY mysql-relay-bin.202754 mysql-relay-bin.index RPM_UPGRADE_MARKER-LAST |
于是：

[root@testdb3 mysql]# mv /app/mysql/mysql-bin.index /app/mysql/mysql-bin.index.bak [root@testdb3 mysql]# service mysql start Starting MySQL (Percona Server)...[ OK ] |
