MySQL错误日志提示innodb_table_stats和innodb_index_stats不存在故障处理

查看MySQL error日志，发现有如下报错

 7efbc586f700 InnoDB: Error: Table "mysql"."innodb_table_stats" not found.

2016-05-22 12:04:11 7efbc586f700 InnoDB: Error: Table "mysql"."innodb_table_stats" not found.

造成这个原因的问题可能是在初始化的过程中，删掉了ibdata1的文件导致，处理的方法

1.删除上述系统表

drop table mysql.innodb_index_stats;

drop table mysql.innodb_table_stats;

2 /etc/init.d/mysqld stop

3 cd /data/3306/data/mysql/

4 rm -rf innodb_index_stats* innodb_table_stats*

5 /etc/init.d/mysqld start

6 mysql> use mysql

Database changed

    ->   `database_name` varchar(64) COLLATE utf8_bin NOT NULL,

    ->   `table_name` varchar(64) COLLATE utf8_bin NOT NULL,
