MySQL innodb_table_stats表不存在的解决方法

MySQL 版本 5.6.14

公司有几台MySQL服务器的错误日志显示,有几个系统表不存在.

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 -rf innodb_index_stats*

rm -rf innodb_table_stats*

rm -rf slave_master_info*

rm -rf slave_relay_log_info*

rm -rf 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...
