CentOS 7部署jar包

适用于 Java项目开发，打包为jar的应用程序部署，操作系统为CentOS 7.9。

安装Java运行时，此处省略800字…

将打包好的*.jar文件、config文件上传到服务器/home/8001目录下。

cd /home/8001
vim run.sh

输入以下内容：

#!/bin/bash
# 修改为jar包名称
AppName=GovServices.jar
# 修改端口号
PortID=8001

# 以下无需修改
# 设置Java虚拟机系统内存参数
JVM_OPTS="-server -Xms256M -Xmx256M -XX:PermSize=128M -XX:MaxPermSize=512M"
PID=""

getpid() {
    TempPID=$(netstat -antlp | grep $PortID | awk '{print $7}')
    echo ${TempPID%%/java}
}

function start() {
    PID=$(getpid)
    if [ x"$PID" != x"" ]; then
        echo "$AppName (pid:$PID) is running..."
    else
        echo "Start $AppName..."
        nohup java -jar $JVM_OPTS $AppName >/dev/null 2>&1 &
        sleep 5
        local t=1
        while [ x"$PID" == x"" ] && [ $t -lt 20 ]; do
            PID=$(getpid)
            if [ x"$PID" != x"" ]; then
                echo "Start $AppName (pid:$PID) success..."
            else
                echo "$((t*5)) seconds..."
                sleep 5
            fi 
            (( t+=1 )) 
        done
        if [ x"$PID" == x"" ]; then
            echo "Failed to start $AppName. See \"cat logs/sys-info.log\" and \"cat logs/sys-error.log\" for details."
        fi
    fi
}

function stop() {
    PID=$(getpid)
    if [ x"$PID" != x"" ]; then
        echo "Stop $AppName (pid:$PID)"
        kill -TERM $PID
        echo "$AppName (pid:$PID) exiting..."
        while [ x"$PID" != x"" ]; do
            sleep 3
            PID=$(getpid)
        done
        echo "$AppName exited."
    else
        echo "$AppName already stopped."
    fi
}

function restart() {
    stop
    sleep 5
    start
}

function status() {
    PID=$(getpid)
    if [ x"$PID" != x"" ]; then
        echo "$AppName (pid:$PID) is running..."
    else
        echo "$AppName is not running..."
    fi
}

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

:wq命令保存退出后，chmod u+x run.sh 授予当前用户执行权限。
服务控制命令：

# 启动
