linux screen 後臺開機自啓動java程序

#!/bin/sh
if [ -z "$STY" ]; then exec screen -dm -S push /bin/bash "$0"; fi
cd ~/server
java -jar push.jar

把以上源碼另存爲xxx.sh 並賦予可執行權限，然後寫入/etc/profile內，

便可實現使用screen在後臺執行java -jar push.jar的操作。

需要先安裝screen

啓動兩遍的坑，最後通過shell來解決

20160727更新：最好的方法是用supervisord 並把supervisord自啓動。
