一、前言
平常工作中,我们的开发的项目部署到linux环境,以jar包的方式运行,涉及jar包的启动、停止、查看状态等,我们可以通过脚本的方式进行维护,减少自己敲打一长串的命令少敲一个字母或者多敲一个字母,方便维护。
二、脚本
vim app.sh
#!/bin/bash
appName=xxxx.jar
if [ -z $appName ]
then
echo "Please check that this script and your jar-package is in the same directory!"
exit 1
fi
killForceFlag=$2
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 -jar $appName --spring.profiles.active=test >log.out 2>&1 &
fi
}
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 -n "The $appName is stopping..."
if [ "$killForceFlag" == "-f" ]
then
echo "by force"
kill -9 $appId
else
echo
kill $appId
fi
fi
}
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
}
function restart()
{
stop
for i in {3..1}
do
echo -n "$i "
sleep 1
done
echo 0
start
}
function help()
{
echo "Usage: $0 {start|stop|restart|status|stop -f}"
echo "Example: $0 start"
exit 1
}
function taillog()
{
tail -f -n 1000 log.out
}
case $1 in
start)
start;;
stop)
stop;;
restart)
restart;;
status)
status;;
taillog)
taillog;;
*)
help;;
esac
三、授权及命令
chmod +x app.sh
启动:app.sh start
停止:app.sh stop -f
查看状态 app.sh status
