在本地安装mysql的服务端,打开cmd,cd到mysql安装目录下的bin目录,bin目录中可以看到多个可执行文件,其中mysqladmin就是可以用于远程关闭mysql服务的。

mysqladmin的参数如下:

Where command is a one or more of: (Commands may be shortened)create databasename Create a new databasedebug Instruct server to write debug information to logdrop databasename Delete a database and all its tablesextended-status Gives an extended status message from the serverflush-hosts Flush all cached hostsflush-logs Flush all logsflush-status Clear status variablesflush-tables Flush all tablesflush-threads Flush the thread cacheflush-privileges Reload grant tables (same as reload)kill id,id,… Kill mysql threadspassword new-password Change old password to new-password, MySQL 4.1 hashing.old-password new-password Change old password to new-password in old format.

ping Check if mysqld is aliveprocesslist Show list of active threads in serverreload Reload grant tablesrefresh Flush all tables and close and open logfilesshutdown Take server downstatus Gives a short status message from the serverstart-slave Start slavestop-slave Stop slavevariables Prints variables availableversion Get version info from server

这里我们只需要其中的-h 参数指定远端主机,-u指定远端登录用户,-p指定需要使用密码认证 最后的命令部分,使用shutdown即可完整命令如下:mysqladmin -h10.101.0.1 -uroot -p123456 shutdown

当然同理,可以远程执行ping processlist reload refresh shutdown status start-slave stop-slave variables version等命令
