ERROR 1794 (HY000): Slave is not configured or fai

mysql 5.7在從庫中止複製進程時出現錯誤，緣由是將複製信息記錄表中了。

錯誤提示：

ERROR 1794 (HY000): Slave is not configured or failed to initialize properly. You must at least set --server-id to enable either a master or a slave. Additional error messages can be found in the MySQL error log.

解決方法：

use mysql
drop table slave_master_info;
drop table slave_relay_log_info;
drop table slave_worker_info;
drop table innodb_index_stats;
drop table innodb_table_stats;

source /usr/coolpad/mysql/share/mysql_system_tables.sql
