php-fpm服务无法完全启动

Question

在我的服务器（FreeBSD 11）上，php-fpm服务不再干净地分级。

# service php-fpm status
php_fpm is not running.

但是如果我搜索正在运行的实例，我会看到它正在工作（实际上，Web应用程序也使用它并且正在工作：

# top | grep php-fpm
572 root          1  20    0   265M  4688K kqread  0   3:58   0.00% php-fpm
50875 www           1  31    0   273M 22188K accept  1   0:12   0.00% php-fpm
50872 www           1  20    0   271M 20816K accept  1   0:10   0.00% php-fpm
51438 www           1  30    0   269M 15024K accept  1   0:05   0.00% php-fpm

如果我杀死它并用手启动它，实际上它已经启动了，但抱怨无法启动（“ service php-fpm restart”上的输出相同）：

# service php-fpm start
Performing sanity check on php-fpm configuration:

/usr/local/etc/rc.d/php-fpm: WARNING: failed to start php_fpm

会产生什么呢？

上面的戈什先生给出了正确的答案。 问题是pid文件，可能在php-fpm.conf中没有这样声明路径/文件名：

include=etc/php-fpm.d/*.conf

[global]
pid = run/php-fpm.pid
events.mechanism = kqueue
error_log = /home/user/logs/php-error.log
