MySQL innodb_table_stats表不存在的解决方法

在做实验时，使用mysqldump命令报错

\[root@linux-mysql02 3306\]\# mysqldump -uroot -p123456 -S /u02/data/3306/mysql.sock -A -B --events | gzip > /opt/rep.sql.gz

mysqldump: Got error: 1146: Table 'mysql.innodb\_index\_stats' doesn't exist when using LOCK TABLES

然后查看错误日志：

\[root@linux-mysql02 ~\]\# vim /u02/data/3306/mysql\_oldboy3306.err

2017-08-09 15:21:10 19726 \[Warning\] InnoDB: Cannot open table mysql/innodb\_index\_stats from the internal data dictionary of InnoDB though the

.frm file for the table exists. See http://dev.mysql.com/doc/refman/5.6/en/innodb-troubleshooting.html for how you can resolve the problem.

\[root@linux-mysql02 ~\]\# mysql -uroot -p123456 -S /u02/data/3306/mysql.sock

mysql> use mysql

mysql> show tables;

mysql> show create table slave\_master\_info\\G

ERROR 1146 (42S02): Table 'mysql.slave\_master\_info' doesn't exist

最后测试发现以下几个系统表不存在.  
innodb\_table\_stats  
innodb\_index\_stats  
slave\_master\_info  
slave\_relay\_log\_info  
slave\_worker\_info

这是因为数据库初始化的时候,dba可能删除过ibdata1文件  
虽然重启之后,数据库会自动创建一个ibdata1文件,但是上述系统表也是innodb引擎,所以不能访问了.  
这虽然不会影响业务,但是使用innobackupex备份的时候,会写入错误日志.  
最后错误日志里,都是这种信息.影响日常检查。

解决的方法.  
1.删除上述系统表  
drop table mysql.innodb\_index\_stats;  
drop table mysql.innodb\_table\_stats;  
drop table mysql.slave\_master\_info;  
drop table mysql.slave\_relay\_log\_info;  
drop table mysql.slave\_worker\_info;

2.删除相关的.frm .ibd文件  
rm -f innodb\_index\_stats\*  
rm -f innodb\_table\_stats\*  
rm -f slave\_master\_info\*  
rm -f slave\_relay\_log\_info\*  
rm -f slave\_worker\_info\*

3.重新创建上述系统表

4.如果是Slave备机,停止复制,记录pos等信息  
mysql> stop slave;  
Query OK, 0 rows affected (0.09 sec)

5.重启数据库

6.如果Slave启动报错,则使用步骤4的信息,重新change master

再删除ibdata1文件的时候,一定要想起系统数据库还有5张innodb表...
