在Linux上讲Java命令行的作为服务运行

Posted 2020-09-03 邓志国

现在Spring等框架可以支持别用War发布而是用Jar发布，这样服务器就不用安装容器了，方便不少。但不安装容器就需要自己来写脚本完成服务的启动、停止、重启。

脚本如下：

#!/bin/bash
#
# chkconfig: 345 70 30
# description: ${description}
# processname: ${processName}

# Source function library.
#!/bin/sh
SERVICE_NAME=${serviceName}
PATH_TO_JAR=${jarFile}
PID_PATH_NAME=/tmp/${serviceName}-pid
case $1 in
    start)
        echo "Starting $SERVICE_NAME ..."
        if [ ! -f $PID_PATH_NAME ]; then
            nohup java -jar ${javaArgs} $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &
                        echo $! > $PID_PATH_NAME
            echo "$SERVICE_NAME started ..."
        else
            echo "$SERVICE_NAME is already running ..."
        fi
    ;;
    stop)
        if [ -f $PID_PATH_NAME ]; then
            PID=$(cat $PID_PATH_NAME);
            echo "$SERVICE_NAME stoping ..."
            kill $PID;
            echo "$SERVICE_NAME stopped ..."
            rm $PID_PATH_NAME
        else
            echo "$SERVICE_NAME is not running ..."
        fi
    ;;
    restart)
        if [ -f $PID_PATH_NAME ]; then
            PID=$(cat $PID_PATH_NAME);
            echo "$SERVICE_NAME stopping ...";
            kill $PID;
            echo "$SERVICE_NAME stopped ...";
            rm $PID_PATH_NAME
            echo "$SERVICE_NAME starting ..."
            nohup java -jar ${javaArgs} $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &
                        echo $! > $PID_PATH_NAME
            echo "$SERVICE_NAME started ..."
        else
            echo "$SERVICE_NAME is not running ..."
        fi
    ;;
