主从复制报错，下面是从库复制状态：

                   Last_Error: Relay log read failure: Could not parse relay log event entry.

中继日志读主库日志失败 ，顺道看下错误日志信息，日志显示从库9点37分时重启了，38分出现主从故障，看样子是因为从库异常重启导致的！

161018 09:37:39 mysqld_safe Number of processes running now: 0

161018 09:37:39 mysqld_safe mysqld restarted

2016-10-18 09:38:49 6042 [ERROR] Slave SQL: Relay log read failure: Could not parse relay log event entry. The possible reasons are: the master's binary log is corrupted (you can check this by running 'mysqlbinlog' on the binary log), the slave's relay log is corrupted (you can check this by running 'mysqlbinlog' on the relay log), a network problem, or a bug in the master's or slave's MySQL code. If you want to check the master's binary log or slave's relay log, you will be able to know their names by issuing 'SHOW SLAVE STATUS' on this slave. Error_code: 1594

解决方法，重新设置主从进程解决：

mysql> stop slave;

Query OK, 0 rows affected (0.02 sec)

mysql> reset slave;

Query OK, 0 rows affected (0.57 sec)

mysql> change master to master_host='192.168.129.150',

    -> master_user='replicat',

    -> master_password='passw',

    -> master_log_file='mysql-bin.000195',

    -> master_log_pos=1037392827;

Query OK, 0 rows affected, 2 warnings (0.07 sec)

mysql> start slave;

Query OK, 0 rows affected (0.03 sec)

以前从库异常重启都没发生这类情况，网上查了相关资料，发现和relay_log_info_repository和relay_log_info_repository这两个参数有关

mysql> show variables like '%relay_log_info_repository%';
+---------------------------+-------+
| Variable_name             | Value |
+---------------------------+-------+
| relay_log_info_repository | FILE  |
+---------------------------+-------+

1 row in set (0.00 sec)

mysql> show variables like '%relay_log_info_repository%';
+---------------------------+-------+
| Variable_name             | Value |
+---------------------------+-------+
| relay_log_info_repository | FILE  |
+---------------------------+-------+

1 row in set (0.00 sec)

把FILE修改成TABLE可以降低这种主从失败发生的概率。
