shell：统一管理jar包启动脚本,控制台指定输出

1.在企业级开发中，公司有多个javaee项目，怎么优雅得管理启动这些应用呢？

2.一般操作： 

• java -jar xxxx.jar
• nohup java -jar xxx.jar >> /home/logs/appname/xxx.log 2>&
• tail 10 xxx.log

3.shell脚本

• sh 执行shell脚本指令
• operate第一个参数 start|stop|status|restart|reload
• appname第二个参数 表示启动的应用名前缀
• nohup java -jar xxx.jar >> /home/logs/appname/xxx.log 2>& 启动命令，将控制台输出到指定目录（即sh st.sh start appname指令）
• tail 10 xxx.log 查看输入的控制台信息（即sh st.sh status appname指令）
• kill -9 pid 结束应用（即sh st.sh stop appname指令）

#!/bin/bash
operate=${1}
appname=${2}

echo "(ps -aef | grep '$2-0.0.1-SNAPSHOT.jar' | grep -v grep | awk '{print $2}')"
pid=$(ps -aef | grep $2-0.0.1-SNAPSHOT.jar | grep -v grep | awk '{print $2}')
echo "$appname pid is $pid."
startJXF(){
  if [ "$pid" == ""  ]; then
        echo -n "$APP_NAME starting: "
        nohup java -jar /home/tools/$appname-0.0.1-SNAPSHOT.jar >> /home/logs/$appname/start.log 2>&1&
  else
        echo "can't start $appname : $appname is running."
        echo -e ""
        exit 1
  fi
}

        echo -n "$APP_NAME reloading: "
        tail -f /home/logs/$appname/start.log
        echo -e ""
