我遇到一个奇怪的问题，当我启动 php-fpm 时，收到以下消息：
> /etc/init.d/php-fpm start
Starting php-fpm ................................... failed
但当我查看日志文件时，看起来一切都很好（我将输出更改为调试）

这些流程存在，而且似乎处理得很好。为什么它会给我一个失败的消息？

值得一提的是，即使 Daniel 已经解决了自己的问题，但仍修复了在全新安装 PHP-FPM 时遇到的 .....failed 错误问题。
php-fpm.conf 文件有一个 pid 文件指令，在新安装中该指令被注释掉。删除 ';' 以写入 pid 文件，启动命令应该不会在默认位置定位 pid 文件时出现问题。
