linux使用shell腳本對java服務進行啓動、重啓、關閉

腳本 app.sh

#!/bin/bash
path=${APP_HOME}
echo $path
app=$path'/bin/app.jar'
args='-Xms1024m -Xmx2048m'
cmd=$1
pid=`ps -ef|grep java|grep $app|awk '{print $2}'`

startup(){
  setsid java -jar $args $app 
}

if [ ! $cmd ]; then
  echo "Please specify args 'start|restart|stop'"
  exit
fi

if [ $cmd == 'start' ]; then
  if [ ! $pid ]; then
    startup
  else
    echo "$app is running! pid=$pid"
  fi
fi

if [ $cmd == 'restart' ]; then
  if [ $pid ]
    then
      echo "$pid will be killed after 3 seconds!"
      sleep 3
      kill -9 $pid
  fi
  startup
fi

if [ $cmd == 'stop' ]; then
  if [ $pid ]; then
    echo "$pid will be killed after 3 seconds!"
    sleep 3
    kill -9 $pid
  fi
  echo "$app is stopped"
fi

使用方式

將app 和args改成對應項目的配置
path是我配置的環境變量,app路徑可以直接寫物理路徑
然後執行chmod +x app.sh添加運行權限
執行./app.sh start或者./app.sh restart即可啓動項目
執行./app.sh stop停止項目運行
