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网站网站文件，其中mysqladmin就是可以用于远程关闭mysql服务的。 mysqladmin的参数如下： mysqladmin Ver 8.42 Distrib 5.5.2-m2, for Win32 on ia32 Copyright 2000-2008 MySQL AB, 2008 Sun Microsystems, Inc. This software comes with ABSOLUTELY NO WARRANTY. This is free software, and you are welcome to modify and redistribute it under the GPL license Administration program for the mysqld daemon. Usage: mysqladmin [OPTIONS] command command…. -c, –count=# Number of iterations to make. This works with -i (–sleep) only. –debug-check Check memory and open file usage at exit . –debug-info Print some debug info at exit. -f, –force Don't ask for confirmation on drop database; with multiple commands, continue even if an error occurs. -C, –compress Use compression in server/client protocol. –character-sets-dir=name Directory where character sets are. –default-character-set=name Set the default character set. -?, –help Display this help and exit. -h, –host=name Connect to host. -b, –no-beep Turn off beep on error. -p, –password[=name] Password to use when connecting to server. If password is not given it's asked from the tty. -W, –pipe Use named pipes to connect to server. -P, –port=# Port number to use for connection or 0 for default to, in order of preference, my.cnf, $MYSQL_TCP_PORT, /etc/services, built-in default (3306). –protocol=name The protocol of connection (tcp,socket,pipe,memory). -r, –relative Show difference between current and previous values when used with -i. Currently works only with extended-status. -O, –set-variable=name Change the value of a variable. Please note that this option is deprecated; you can set variables directly with –variable-name=value. –shared-memory-base-name=name Base name of shared memory. -s, –silent Silently exit if one can't connect to server. -S, –socket=name Socket file to use for connection. -i, –sleep=# Execute commands again and again with a sleep between. –ssl Enable SSL for connection (automatically enabled with other flags). Disable with –skip-ssl. –ssl-ca=name CA file in PEM format (check OpenSSL docs, implies –ssl). –ssl-capath=name CA directory (check OpenSSL docs, implies –ssl). –ssl-cert=name X509 cert in PEM format (implies –ssl). –ssl-cipher=name SSL cipher to use (implies –ssl). –ssl-key=name X509 key in PEM format (implies –ssl). –ssl-verify-server-cert Verify server's “Common Name” in its cert against hostname used when connecting. This option is disabled by default. -u, –user=name User for login if not current user. -v, –verbose Write more information. -V, –version Output version information and exit. -E, –vertical Print output vertically. Is similar to –relative, but prints output vertically. -w, –wait[=#] Wait and retry if connection is down. –connect_timeout=# –shutdown_timeout=# Variables (–variable-name=value) and boolean options {FALSE|TRUE} Value (after reading options) ——————————— —————————– count 0 debug-check FALSE debug-info FALSE force FALSE compress FALSE character-sets-dir (No default value) default-character-set auto host (No default value) no-beep FALSE port 3306 relative FALSE shared-memory-base-name (No default value) socket (No default value) sleep 0 ssl FALSE ssl-ca (No default value) ssl-capath (No default value) ssl-cert (No default value) ssl-cipher (No default value) ssl-key (No default value) ssl-verify-server-cert FALSE user (No default value) verbose FALSE vertical FALSE connect_timeout 43200 shutdown_timeout 3600 Default options are read from the following files in the given order: C:\WINDOWS\my.ini C:\WINDOWS\my.cnf C:\my.ini C:\my.cnf F:\MySQL\my.ini F:\MySQL\my.cnf The following groups are read: mysqladmin client The following options may be given as the first argument: –print-defaults Print the program argument list and exit –no-defaults Don't read default options from any options file –defaults-file=# Only read default options from the given file # –defaults-extra-file=# Read this file after the global files are read Where command is a one or more of: (Commands may be shortened) create databasename Create a new database debug Instruct server to write debug information to log drop databasename Delete a database and all its tables extended-status Gives an extended status message from the server flush-hosts Flush all cached hosts flush-logs Flush all logs flush-status Clear status variables flush-tables Flush all tables flush-threads Flush the thread cache flush-privileges Reload grant tables (same as reload) kill id,id,… Kill mysql threads password 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 alive processlist Show list of active threads in server reload Reload grant tables refresh Flush all tables and close and open logfiles shutdown Take server down status Gives a short status message from the server start-slave Start slave stop-slave Stop slave variables Prints variables available version Get version info from server 这里咱们只需要其中的-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 最后的开始执行命令部分，使用shutdown即可 完整开始执行命令如下： 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等开始执行命令mysql 无法连接问题的定位和修复过程分享
