我一直试图让php-fpm（w nginx）使用默认端口（9000）而它只是不起作用。我正在尝试使用php 7.1（也试过7.0和5.6）。服务开始很好，我也可以看到端口打开并在ss / netstat中被监听。 php-fpm日志中没有错误。最初我认为它可能是一个nginx问题，但当我尝试使用cgi-fcgi -bind -connect 127.0.0.1:9000直接测试连接时，它只是没有响应，我最终得到一个无法连接错误。请求不会记录在访问日志中（启用访问日志时）。
# cgi-fcgi -bind -connect 127.0.0.1:9000
Could not connect to 127.0.0.1:9000
有些时候重新启动它只是随机工作一些请求（有时1个请求，有时10个，不同）然后它再次停止工作。 php-fpm状态中的请求计数不再增加。
它的行为没有任何押韵或节奏，即使是那些少量的请求，我找不到一致的方法让它工作。
这个问题现在已经困扰了我2天，而且它与日志中的任何内容都不一致。请帮忙。感谢您提前回复。
到目前为止我尝试了什么 -

listen = 9000
在池配置文件（/etc/php/7.0/fpm/pool.d/www.conf）中。
如果不需要侦听特定IP，则需要指定“仅端口”以侦听该端口上的所有IP。
答案 1 :(得分：0)
我遇到了同样的问题，找不到任何解决方案。
所以我写了一些代码来解决这个问题
带有套接字编程的 vb 代码，它在计时器中连接到端口 9000，然后检查套接字状态和错误句柄。
如果状态不是 sckConnected 或错误引发连接被拒绝，则结束 php-cgi.exe 或 php-fpm 然后重新执行它们。
虽然这不是解决这个问题的最好方法！
