我通过 TCP 使用 php-fpm，因为我的目的是对其进行负载平衡。
我是否应该在每台服务器上都有 PHP 文件？
或者我可以将其存储在 Web 服务器 (Lighttpd) 上吗？404 Error当我尝试请求一个简单的 php 文件时，我收到了。该文件存储在 lighttpd 服务器上，而 php-fpm 在另一台机器上运行。
这是我在 lighttpd 上的配置：
server.modules += ( "mod_fastcgi" )
fastcgi.debug = 1
fastcgi.server += ( ".php" =>
((
"host" => "10.5.0.3",
"port" => "9000",
"broken-scriptfilename" => "enable"
))
)
以及 php-fpm 池配置：
[www]
listen = 127.0.0.1:9000
user = www-data
group = www-data
pm = ondemand
pm.max_children = 5
pm.start_servers = 2
pm.process_idle_timeout = 10s;
pm.max_requests = 500

注意：它在 docker 内部运行以模拟该情况，如果需要一些有关 docker 的附加信息来调试此行为，请告诉我。
答案1
您需要在运行 PHP-FPM 的服务器上拥有 PHP 文件。Lighttpd 仅将请求传递给 PHP-FPM，而不是包含内容的实际文件。
您还需要拥有 PHP 脚本在 PHP-FPM 服务器上可能使用的所有资源。
实现此目的的一个选项是让 lighttpd 计算机通过网络文件系统共享文件。但是，这可能会带来性能问题。
集群文件系统是另一种选择。
我使用lsyncd守护进程将文件从单个系统同步到多个目标。这样，所有 PHP-FPM 服务器都拥有脚本的本地副本，并且文件访问不会产生任何性能开销。
