Shell脚本案例:jar包启动和运行管理

使用shell脚本管理jar应用,支持:启动、重启、停止、运行状态检测等简单功能

#!/bin/sh
# 1. 命令:./app.sh start 启动 stop 停止 restart 重启 status 状态
# 2. 使用前修改AppName为你的jar名称
AppName=test.jar

# JVM参数
JVM_OPTS="-Dname=$AppName  -Duser.timezone=Asia/Shanghai -Xms512m -Xmx1024m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=512m -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintGCDateStamps  -XX:+PrintGCDetails -XX:NewRatio=1 -XX:SurvivorRatio=30 -XX:+UseParallelGC -XX:+UseParallelOldGC"
APP_HOME=`pwd`
LOG_PATH=$APP_HOME/logs/$AppName.log

if [ "$1" = "" ]; then
    echo -e "\033[0;31m 未输入操作名 \033[0m  \033[0;34m {start|stop|restart|status} \033[0m"
    exit 1
fi

if [ "$AppName" = "" ]; then
    echo -e "\033[0;31m 未输入应用名 \033[0m"
    exit 1
fi

function start() {
    PID=`ps -ef |grep java|grep $AppName|grep -v grep|awk '{print $2}'`
    if [ x"$PID" != x"" ]; then
        echo "$AppName is running..."
    else
        nohup java $JVM_OPTS -jar $AppName > /data/test/nohup 2>&1 & echo "Start $AppName success..."
    fi
}

function stop() {
    echo "Stop $AppName"
    PID=""
    query(){
      PID=`ps -ef |grep java|grep $AppName|grep -v grep|awk '{print $2}'`
    }

    query
    if [ x"$PID" != x"" ]; then
       kill -TERM $PID
       echo "$AppName (pid:$PID) exiting..."
       while [ x"$PID" != x"" ]
       do
         sleep 1
         query
       done
       echo "$AppName exited."
    else
       echo "$AppName already stopped."
    fi
}

function restart() {
    stop
    sleep 2
    start
}

function status() {
    PID=`ps -ef |grep java|grep $AppName|grep -v grep|wc -l`
    if [ $PID != 0 ];then
        echo "$AppName is running..."
    else
        echo "$AppName is not running..."
    fi
}

case $1 in
    start)
    start;;
    stop)
    stop;;
    restart)
    restart;;
    status)
    status;;
    *)

esac

使用方法:

启动:./app.sh start

停止:./app.sh stop

重启:./app.sh restart

本脚本比较简单,如果需要更专业的工具可以尝试一下下面这些:

  • jarboot
