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
