MySQL主从报错解决:Failed to initialize the master info structure

大清早收到一个 MySQL 的自定义语言告警 :replication interrupt,看来是主从同步报错了。
登陆 MySQL,执行 show slave status \G 发现 salve 已经停止了,于是使用 start slave 启动,结果有如下报错:

ERROR 1201 (HY000): Could not initialize master info structure; more error messages can be found in the MySQL error log

搜索了下,网上给出的解决办法基本都是:

①、执行 reset slave;

②、重新执行 change master:

mysql> change master to 
    -> master_host='192.168.1.100',
    -> master_port=3306,
    -> master_user='repl',
    -> master_password='repl',
    -> master_log_file='mysql-bin.000051',
    -> master_log_pos=254105;

③、执行 start slave

于是试了下,发现还是一样的报错,顺着报错信息,看了下 error 日志:

160324  6:40:10 [ERROR] log *** glibc detected *** /data/mysql/bin/mysqld: corrupted double-linked list: 0x00002ab038100ab0 *** listed in the index, but failed to stat

160324  9:37:47 [ERROR] Error counting relay log space

发现其中频繁出现如下错误:

ist: 0x00002ab038100ab0 *** listed in the index, but failed to stat

于是,把 MySQL 数据文件目录下的 index info 文件都看了一遍,结果发现 Centos64-relay-bin.index 文件中出现异常内容:

MySQL主从报错解决:Failed to initialize the master info structure

这个文件正常情况应该是记录了 bin-log 文件名称才对,比如:

./Centos64-relay-bin.002064
./Centos64-relay-bin.002065
./Centos64-relay-bin.002066
./Centos64-relay-bin.002067
./Centos64-relay-bin.002068
./Centos64-relay-bin.002069
./Centos64-relay-bin.002070

因此,将 Centos64-relay-bin.index 这个文件 mv 重命名,然后重启 MySQL,重新按照上文从网上照来的的步骤:reset、change master、start 成功搞定!

如果你也遇到类似问题,可以先按照网上提供的三个步骤试试,如果还是和本文类似的报错,请特别看下 MySQL 数据目录下的这几种文件:

mysql-bin.index

relay-log.info

主机名-relay-bin.index

可以尝试将他们重命名或移走,重启 MySQL 再走一遍上面的三个步骤应该可以搞定了!
