How to use php-fpm in tcp mode on an external machine?

Question

I'm using php-fpm over TCP, because Is my intention load balance it.

Should I have PHP files on every server?

Or can I store it at the web server (Lighttpd)? I'm receiving 404 Error when trying to request a simple php file. That file is stored at lighttpd server and the php-fpm is running on another machine.

It's my configuration at lighttpd:

server.modules += ( "mod_fastcgi" )
fastcgi.debug = 1


fastcgi.server += ( ".php" =>
        ((
                "host" => "10.5.0.3",
                "port" => "9000",
                "broken-scriptfilename" => "enable"
        ))
)

And the php-fpm pool config:

[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 log:

[13-Sep-2017 20:22:54] NOTICE: fpm is running, pid 1
[13-Sep-2017 20:22:54] NOTICE: ready to handle connections

And lighttpd log:

Note: It's running inside docker to simulate that condition, if some aditional information about docker is necessary to debug this behavior please let me know.

You need to have the PHP files on the servers where PHP-FPM is running. Lighttpd only passes the request to PHP-FPM, not the actual files which contain the contents.

You need to also have all possible resources that PHP scripts use on the PHP-FPM servers.

One option to achieve this is to have the lighttpd machine share the files over a network file system. However, this could have performance issues.

A cluster file system is another option.

I have used lsyncd daemon to synchronize the files from a single system to multiple destinations. This way all PHP-FPM servers have local copies of the scripts, and there is no performance overhead for file access.

If looking at these tools, check out [csync2](http://oss.linbit.com/csync2/) as well. – gxx Sep 14 '17 at 11:35
Thanks for your time to answer my questions. It clarified a lot about the design of this clusterization. @gf_ It's a good tool to sync among clusters. I recommend it. – LeonanCarvalho Sep 14 '17 at 12:14
