Perform mysqldump backup data times wrong

Environment
MySQL version 5.6.28

Problem:
Execution mysqldump The following error occurred, small white when performing mysqldump backup, is to perform a single error
1, Mysqldump:got error:1146:table ' MySQL. innodb_index_stats' doesn ' t exist when using LOCK TABLES
2, Mysqldump:got error:1146:table ' MySQL. innodb_table_stats' doesn ' t exist when using LOCK TABLES
3, Mysqldump:got error:1146:table ' MySQL. slave_master_info' doesn ' t exist when using LOCK TABLES
4, Mysqldump:got error:1146:table ' MySQL. slave_relay_log_info' doesn ' t exist when using LOCK TABLES
5, Mysqldump:got error:1146:table ' MySQL. slave_worker_info' doesn ' t exist when using LOCK TABLES

How to resolve:
1, delete the above system table,
mysql> drop table mysql.innodb_index_stats;
mysql> drop table mysql.innodb_table_stats;
mysql> drop table Mysql.slave_master_info;
mysql> drop table Mysql.slave_relay_log_info;
mysql> drop table Mysql.slave_worker_info;
The following error may be reported:
mysql> drop table mysql.innodb_index_stats;
ERROR 1051 (42S02): Unknown table ' Mysql.innodb_index_stats '
Use the following 2 delete method

2. Delete the associated. frm. ibd file under MySQL database and restart the database
[Email protected] mysql]# RM-RF innodb_index_stats.*
[Email protected] mysql]# RM-RF innodb_table_stats.*
[Email protected] mysql]# RM-RF slave_master_info.*
[Email protected] mysql]# RM-RF slave_relay_log_info*
[Email protected] mysql]# RM-RF slave_worker_info*
[Email protected] mysql]# systemctl restart mysqld

3, log in the database, re-create the above system table (copy the corresponding code below to create the corresponding table)

4, if the database has Master-slave Master architecture, restore the appeal form, slave start error, solution please Baidu
