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：

1

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

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

./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！

PHP多次调用Mysql存储过程报错解决办法

PHP多次调用Mysql数据库的存储过程会出现问题,主要问题为存储过程中执行多次SQL语句不能一一释放导致的,网上找了一些解决办法,比如使用 multi_query 然后一个一个释放,但是发现根本不适合我们的项目,我们使用CI框架写的,更多的是使用CI的数据库处理方法.所以只能另辟蹊径. 一次偶然,把Mysql链接方式改成了mysqli,两种不同的PHP连接mysql的扩展,官方在高版本中推荐使用mysqli,结果却奇迹般好了,使用Mysql长连接也行,天意么? PHP多次调用Mysql存储过程
