Java服务启动脚本模板
在我们日常开发中,需要将写好的java代码打jar包,然后上传到服务器上进行运行 使用此脚本可以简化对程序 启动、重启、停止等工作的重复操作
#!/bin/bash
app=demo.jar
args=-Xms512m -Xmx512m
cmd=$1
pid=`ps -ef |grep $app | grep -v grep| awk {print $2}`
startup(){
#nohup java -jar $args $app > logs/server.log &
nohup java -jar $app >/dev/null 2>&1 &
}
if [ ! $cmd ]; then
echo "Please specify args start|restart|stop|status"
exit
fi
if [ $cmd == start ]; then
if [ ! $pid ]; then
startup
else
echo "$app is running! pid=$pid"
fi
fi
if [ $cmd == status ]; then
if [ $pid ]; then
echo "$app is running! pid=$pid"
else
echo "$app is stop! "
fi
fi
if [ $cmd == restart ]; then
if [ $pid ]
then
echo "$pid will be killed after 2 seconds!"
sleep 2
kill -9 $pid
fi
startup
fi
if [ $cmd == stop ]; then
if [ $pid ]; then
echo "$pid will be killed after 2 seconds!"
sleep 2
kill -9 $pid
fi
echo "$app is stopped"
fi
使用说明:
- 脚本中修改参数 app:jar包名 args:jvm启动参数
- 服务器中修改脚本权限 chmod 755 server.sh
- 格式化字符 sed -i ‘s/ $//’ server.sh
- 使用 sh server.sh start sh server.sh restart sh server.sh status sh server.sh stop
