MariaDB stop slave用途：

　　1、环境描述
　　MariaDB 10.1.35
　　CentOS 6.8

　　2、stop slave命令

　　root@MariaDB0 07:55: [(none)]> help stop
　　ERROR 2006 (HY000): MySQL server has gone away
　　No connection. Trying to reconnect...
　　Connection id:    21
　　Current database: *** NONE ***

　　Name: 'STOP SLAVE'
　　Description:
　　Syntax:
　　STOP SLAVE [thread_types]

　　Like START SLAVE, this statement may be used with the IO_THREAD and
　　SQL_THREAD options to name the thread or threads to be stopped.

　　*Note*: In MySQL 5.5, STOP SLAVE waits until the current replication
　　event group affecting one or more non-transactional tables has finished
　　executing (if there is any such replication group), or until the user
　　issues a KILL QUERY or KILL CONNECTION statement. (Bug #319, Bug
　　#38205)
