本文分享了一款用于一键启动、停止、重启、备份和查询状态的Shell脚本，该脚本针对项目部署中的jar文件进行操作，提高了运维效率。

最近部署项目写了一个shell脚本用于文件夹内jar文件的一键启动和停止，包括状态查询等；和大家共享一下！

贴上代码：

#!/bin/bash
version="1.0.1";

JAVA=java
JAVA_HOME=/opt/jdk1.8
JAVA=$JAVA_HOME/bin/java

appName=$2
if [ -z $appName ];then
    appName=`ls -t |grep .jar$ |head -n1`
fi

#一键启动
function start()
{
	count=`ps -ef |grep java|grep $appName|wc -l`
	if [ $count != 0 ];then
		echo "Maybe $appName is running, please check it..."
	else
		echo "The $appName is starting..."
		nohup $JAVA -Xmx2048m -Xms1024m -XX:PermSize=512M -XX:MaxNewSize=512M -XX:MaxPermSize=1024M -jar ./$appName > ./console.out 2>&1 &
	fi
}

#一键结束
function stop()
{
	appId=`ps -ef |grep java|grep $appName|awk '{print $2}'`
	if [ -z $appId ];then
	    echo "Maybe $appName not running, please check it..."
	else
        echo "The $appName is stopping..."
        kill $appId
	fi
}

#一键重启
function restart()
{
    # get release version
    releaseApp=`ls -t |grep .jar$ |head -n1`
    
    # get last version 
    lastVersionApp=`ls -t |grep .jar$ |head -n2 |tail -n1`

    appName=$lastVersionApp
    stop
    for i in {5..1}
    do
        echo -n "$i "
        sleep 1
    done
    echo 0
    
    backup
    
    appName=$releaseApp
    start
}

#一键备份
function backup() 
{
    # get backup version
    backupApp=`ls |grep -wv $releaseApp$ |grep .jar$`
    
    # create backup dir
    if [ ! -d "backup" ];then
        mkdir backup
    fi
    
    # backup
    for i in ${backupApp[@]}
    do
        echo "backup" $i
        mv $i backup
    done
}

#状态查询
function status()
{
    appId=`ps -ef |grep java|grep $appName|awk '{print $2}'`
	if [ -z $appId ] 
	then
	    echo -e "\033[31m Not running \033[0m" 
	else
	    echo -e "\033[32m Running [$appId] \033[0m" 
	fi
}

#菜单
function usage()
{
    echo "Usage: $0 {start|stop|restart|status|stop -f}"
    echo "Example: $0 start"
    exit 1
}

case $1 in
	start)
	start;;

	stop)
	stop;;
	
	restart)
	restart;;
	
	status)
	status;;
	
	*)
	usage;;
