rocketmq 启动脚本

RocketMQ的启动脚本主要有两种方式，一种是通过init.d方式启动，另一种是通过chkconfig方式启动。下面是两种方式的示例脚本：

1. init.d方式启动脚本（/etc/init.d/rocketmq-namesrv）：

#!/bin/sh
#chkconfig: 2345 65 35
#description: start or stop rocketmq using chkconfig

dir=/app/rocketmq/bin
export JAVA_HOME=/usr/local/jdk
ret=0

start() {
    if [ -f $dir/mqnamesrv ]; then
        echo "starting rocketmq namesrv.."
        cd $dir
        nohup sh mqnamesrv >> namesrv.log 2>&1 &
        ret=$?
        echo "start success"
        return $ret
    fi
}

stop() {
    if [ -f $dir/mqshutdown ]; then
        echo "stopping rocketmq namesrv.."
        cd $dir
        ./mqshutdown namesrv
        ret=$?
        echo "stop success"
        return $ret
    fi
}

case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    restart)
        echo "restarting rocketmq namesrv.."
        $0 stop
        sleep 1
        $0 start
        ;;
    *)
        echo $"Usage:$0 {start|stop|restart}"
        exit 1
        ;;
esac

exit $ret

2. chkconfig方式启动脚本（/etc/rc.d/init.d/rocketmq-namesrv）：

#!/bin/sh
#chkconfig: 2345 65 35
#description: start or stop rocketmq using chkconfig

dir=/app/rocketmq/bin
export JAVA_HOME=/usr/local/jdk
ret=0

start() {
    if [ -f $dir/mqnamesrv ]; then
        echo "starting rocketmq namesrv.."
        cd $dir
        nohup sh mqnamesrv >> namesrv.log 2>&1 &
        ret=$?
        echo "start success"
        return $ret
    fi
}

stop() {
    if [ -f $dir/mqshutdown ]; then
        echo "stopping rocketmq namesrv.."
        cd $dir
        ./mqshutdown namesrv
        ret=$?
        echo "stop success"
        return $ret
    fi
}

case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    restart)
        echo "restarting rocketmq namesrv.."
        $0 stop
        sleep 1
        $0 start
        ;;
    *)
        echo $"Usage:$0 {start|stop|restart}"
        exit 1
        ;;
esac

exit $ret
