    一、使用脚本

    • 启动:./start.sh start

    • 停止:./start.sh stop

    • 重启:./start.sh restart

    • 输出运行状态:./start.sh status

    二、编写脚本

    1、创建文件

    start.sh 文件放至 jar 同目录

    2、添加内容

    #!/bin/bash
    #这里可替换为你自己的执行程序,其他代码无需更改
    APP_NAME=txlcn-tm-5.0.2.RELEASE.jar
    #使用说明,用来提示输入参数
    usage() {
    echo "Usage: sh 脚本名.sh [start|stop|restart|status]"
    exit 1
    }
    #检查程序是否在运行
    is_exist(){
    pid=`ps -ef|grep $APP_NAME|grep -v grep|awk '{print $2}' `
    #如果不存在返回1,存在返回0
    if [ -z "${pid}" ]; then
    return 1
    else
    return 0
    fi
    }
    #启动方法
    start(){
    is_exist
    if [ $? -eq "0" ]; then
    echo "${APP_NAME} is already running. pid=${pid} ."
    else
    nohup java  -Xms512m -Xmx1024m -XX:NewRatio=2 -XX:SurvivorRatio=8 -XX:+PrintGCDetails -XX:+UseSerialGC -jar /usr/local/work/lcn/$APP_NAME > log.txt &
    echo "${APP_NAME} start success"
    fi
    }
    #停止方法
    stop(){
    is_exist
    if [ $? -eq "0" ]; then
    kill -9 $pid
    else
    echo "${APP_NAME} is not running"
    fi
    }
    #输出运行状态
    status(){
    is_exist
    if [ $? -eq "0" ]; then
    echo "${APP_NAME} is running. Pid is ${pid}"
    else
    echo "${APP_NAME} is NOT running."
    fi
    }
    #重启
    restart(){
    stop
    start
    }
    #根据输入参数,选择执行对应方法,不输入则执行使用说明
    case "$1" in
    "start")
    start
    ;;
    "stop")
    stop
    ;;
    "status")
    status
    ;;
    "restart")
    restart
    ;;
    *)
    usage
    ;;
    esac
