爲了php-fpm管理方便，從php安裝目錄拷貝了啓動腳本，更改相應路徑，然後執行添加啓動服務，出現如下錯誤。
service php-fpm does not support chkconfig
經過多方查找，原來是啓動腳本中缺少了下面兩行內容：
# chkconfig: 2345 15 95
# description: PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation \
# with some additional features useful for sites of any size, especially busier sites.
其中2345是默認啓動級別，級別有0-6共7個級別。
等級0表示：表示關機
等級1表示：單用戶模式
等級2表示：無網絡連接的多用戶命令行模式
等級3表示：有網絡連接的多用戶命令行模式
等級4表示：不可用
等級5表示：帶圖形界面的多用戶模式
等級6表示：重新啓動
15是啓動優先級，95是停止優先級，優先級範圍是0－100，數字越大，優先級越低。
啓動腳本如下：
#!/bin/bash
# chkconfig: 2345 15 95
