MySQL innodb_table_stats table does not exist

MySQL innodb_table_stats table does not exist

MySQL version 5.6.14

The company's error logs for several MySQL servers show that several system tables do not exist.
Innodb_table_stats
Innodb_index_stats
Slave_master_info
Slave_relay_log_info
Slave_worker_info

This is because the dba may have deleted the ibdata1 file during database initialization.
After the restart, the database will automatically create an ibdata1 file, but the above system table is also an innodb engine, so it cannot be accessed.
This does not affect services, but error logs are written when innobackupex is used for backup.
This information is found in the last error log, which affects daily checks.

Solution.
1. Delete the above system table
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. delete the related. frm. ibd file.
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. Recreate the system table
Create table 'innodb _ index_stats '(

4. If it is an Slave, stop copying and record pos and other information
Mysql> stop slave;
Query OK, 0 rows affected (0.09 sec)

5. Restart the database

6. If an error is reported when Slave is started, use the information in Step 4 to change the master again.

When deleting the ibdata1 file, remember that there are five innodb tables in the system database...
