shell：統一管理jar包啓動腳本,控制檯指定輸出

1.在企業級開發中，公司有多個javaee項目，怎麼優雅得管理啓動這些應用呢？

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腳本

• sh 執行shell腳本指令
• operate第一個參數 start|stop|status|restart|reload
• appname第二個參數 表示啓動的應用名前綴
• nohup java -jar xxx.jar >> /home/logs/appname/xxx.log 2>& 啓動命令，將控制檯輸出到指定目錄（即sh st.sh start appname指令）
• tail 10 xxx.log 查看輸入的控制檯信息（即sh st.sh status appname指令）
• kill -9 pid 結束應用（即sh st.sh stop appname指令）
