swoole项目服务管理脚本 (类似于nginx/php-fpm)

导语

看着nginx mysql php-fpm 都自有相关的服务管理脚本，都是服务器端服务，很多swooler都是人肉来进行操作，也有很多朋友在群里问这方面的问题，所以这里分享一下我的经验。

目标

实现 start|stop|force-quit|restart|reload|reloadtask|status 这些命令

思路

在进程名上设置服务相关的信息，然后跟据进程名来或取相关进程的id

要点

假设我现在的服务叫zmail_server (邮件发送服务：https://github.com/shenzhe/zmail)

1) 主进程：在onStart回调，通过swoole_set_process_name进行进程名设置 

关键代码：

swoole_set_process_name(' zmail_server running tcp://0.0.0.0:9501 master:" . $server->master_pid);

2) 管理进程：在onManagerStart回调，通过swoole_set_process_name进行进程名设置 

关键代码：

swoole_set_process_name(' zmail_server manager:" . $server->manager_id);

完整脚本,按需修改

                    exit 1

                fi

                echo -n "Starting mail server "

                ####下面一行修改为你的php运行脚本#########

                echo " done"

        ;;

        stop)

                PID=`getMasterPid`

                if [ -z "$PID" ]; then

                    echo -n "mail server is not running"

                    exit 1

                fi

                echo -n "Gracefully shutting down mail server "

                kill $PID

                echo " done"

        ;;

        status)

                PID=`getMasterPid`

                if [ -n "$PID" ]; then

                    echo -n "mail server is running"

                else

                    echo -n "mail server is not running"

                fi

        ;;

        force-quit)

                $0 stop

        ;;

        restart)

                $0 stop

                $0 start

        ;;

        reload)

                MID=`getManagerPid`

                if [ -z "$MID" ]; then

                    echo -n "mail server is not running"

                    exit 1

                fi

                echo -n "Reload service mail_server "

                kill -USR1 $MID

                echo " done"

        ;;

        reloadtask)

                MID=`getManagerPid`

                if [ -z "$MID" ]; then

                    echo -n "mail server is not running"

                    exit 1

                fi

                echo -n "Reload service mail_server"

                kill -USR2 $MID

                echo " done"

        ;;

        *)

                echo "Usage: $0 {start|stop|force-quit|restart|reload|reloadtask|status}"

                exit 1

        ;;

esac

开机自启

1. 把这个脚本，放到/etc/init.d/zmail_server下

2. chmod +x /etc/init.d/zmail_server  使其可执行

3. chkconfig --add zmail_server  加入开机启动

运行结果

执行：/etc/init.d/mail_server start

终于可以和nginx/php-fpm 一样管理了。
