转： 快捷启动、停止、重启、杀死指定端口MySQL进程的脚本

转自：http://blog.s135.com/read.php/359.htm

 写了一个shell脚本，可以在同一台Linux服务器的不同端口，运行多个MySQL服务的情况下，快捷启动、停止、重启、杀死指定端口的MySQL进程。

vi /usr/local/bin/mysql.sh

输入以下内容（因各服务器的MySQL配置不同，可能需要修改的部分已用红色标注）：

#!/bin/sh

mysql_port=$2
mysql_username="root"
mysql_password="123456"

function_start_mysql()
{
   printf "Starting MySQL..."n"
   /bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &
}

function_stop_mysql()
{
   printf "Stoping MySQL..."n"
   /usr/local/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -h localhost -P ${mysql_port} shutdown
}

function_restart_mysql()
{
   printf "Restarting MySQL..."n"
   function_stop_mysql
   function_start_mysql
}

function_kill_mysql()
{
   kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}')
   kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}')
}

if [ "$1" = "start" ]; then
   function_start_mysql
elif [ "$1" = "stop" ]; then
   function_stop_mysql
elif [ "$1" = "restart" ]; then
   function_restart_mysql
elif [ "$1" = "kill" ]; then
   function_kill_mysql
else
   printf "Usage: mysql.sh {start|stop|restart|kill}"n"
fi

赋予脚本可执行权限：

chmod +x /usr/local/bin/mysql.sh

脚本执行方法：

mysql.sh start 3306
mysql.sh stop 3306
mysql.sh restart 3306
mysql.sh kill 3306
