我使用TCP上的php-fpm，因为我的意图是负载平衡它。
我应该在每台服务器上有PHP文件吗？
或者我可以将它存储在Web服务器（Lighttpd）？ 我试图请求一个简单的PHP文件时收到404 Error 。 该文件存储在lighttpd服务器上，php-fpm在另一台机器上运行。
这是我在lighttpd的configuration：
server.modules += ( "mod_fastcgi" ) fastcgi.debug = 1 fastcgi.server += ( ".php" => (( "host" => "10.5.0.3", "port" => "9000", "broken-scriptfilename" => "enable" )) )
和PHP-FPM池configuration：
[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
PHP-FPM日志：

注意：它是在docker中运行的，以模拟这种情况，如果需要关于docker的一些辅助信息来debugging此行为，请让我知道。
您需要在运行PHP-FPM的服务器上安装PHP文件。 Lighttpd只将请求传递给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服务器上使用的所有可能的资源。
实现这一目的的一个select是使lighttpd机器通过networking文件系统共享文件。 但是，这可能会有性能问题。
一个群集文件系统是另一种select。
我使用lsyncd守护程序将单个系统中的文件同步到多个目标。 这样所有的PHP-FPM服务器都有脚本的本地副本，并且没有文件访问的性能开销。
