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
(责任编辑：admin)mysql.sh stop 3306 mysql.sh restart 3306 mysql.sh kill 3306 |
