为了php-fpm管理方便，从php安装目录拷贝了启动脚本，更改相应路径，然后执行添加启动服务，出现如下错误。
service php-fpm does not support chkconfig
经过多方查找，原来是启动脚本中缺少了下面两行内容：
# 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是默认启动级别，级别有0-6共7个级别。
等级0表示：表示关机
等级1表示：单用户模式
等级2表示：无网络连接的多用户命令行模式
等级3表示：有网络连接的多用户命令行模式
等级4表示：不可用
等级5表示：带图形界面的多用户模式
等级6表示：重新启动
15是启动优先级，95是停止优先级，优先级范围是0－100，数字越大，优先级越低。
启动脚本如下：
#!/bin/bash
# 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.
