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:

发现其中频繁出现如下错误:
1
|
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:
这个文件正常情况应该是记录了 bin-log文件名称才对,比如:
1
2
3
4
5
6
7
|
./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!
