Apache 2.4 + PHP-FPM + ProxyPassMatch

apache-2.4php-fpm

I recently installed Apache 2.4 on my local machine, together with PHP 5.4.8 using PHP-FPM.

Everything went quite smoothly (after a while…) but there is still a strange error:

I configured Apache for PHP-FPM like this:

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot "/Users/apfelbox/WebServer"
    ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/Users/apfelbox/WebServer/$1
</VirtualHost>

It works, for example if I call http://localhost/info.php I get the correct phpinfo() (it is just a test file).

If I call a directory however, I get a 404 with body File not found. and in the error log:

[Tue Nov 20 21:27:25.191625 2012] [proxy_fcgi:error] [pid 28997] [client ::1:57204] AH01071: Got error 'Primary script unknown\n'

Update

I now tried doing the proxying with mod_rewrite:

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot "/Users/apfelbox/WebServer"

    RewriteEngine on    
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/Users/apfelbox/WebServer/$1 [L,P]
</VirtualHost>

But the problem is: it is always redirecting, because on http://localhost/ automatically http://localhost/index.php is requested, because of 

DirectoryIndex index.php index.html

Update 2

Ok, so I think "maybe check whether there is a file to give to the proxy first:

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot "/Users/apfelbox/WebServer"

    RewriteEngine on    
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/Users/apfelbox/WebServer/$1 [L,P]
</VirtualHost>

Now the complete rewriting does not work anymore…

Update 3

Now I have this solution:

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot "/Users/apfelbox/WebServer"

    RewriteEngine on    
    RewriteCond /Users/apfelbox/WebServer/%{REQUEST_FILENAME} -f
    RewriteRule ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/Users/apfelbox/WebServer/$1 [L,P]
</VirtualHost>

First check, that there is a file to pass to PHP-FPM (with the full and absolute path) and then do the rewriting.

This does not work when using URL rewriting inside a subdirectory, also it fails for URLs like http://localhost/index.php/test/
So back to square one.

Any ideas?

After hours of searching and reading Apache documentation I've come up with a solution that allows to use the pool, and also allow the Rewrite directive in .htaccess to work even when the url contains .php files.

<VirtualHost ...>

 ...

 # This is to forward all PHP to php-fpm.
 <FilesMatch \.php$>
   SetHandler "proxy:unix:/path/to/socket.sock|fcgi://unique-domain-name-string/"
 </FilesMatch>

 # Set some proxy properties (the string "unique-domain-name-string" should match
 # the one set in the FilesMatch directive.
 <Proxy fcgi://unique-domain-name-string>
   ProxySet connectiontimeout=5 timeout=240
 </Proxy>

 # If the php file doesn't exist, disable the proxy handler.
 # This will allow .htaccess rewrite rules to work and 
 # the client will see the default 404 page of Apache
 RewriteCond %{REQUEST_FILENAME} \.php$
 RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_URI} !-f
 RewriteRule (.*) - [H=text/html]

</VirtualHost>

As per Apache documentation, the SetHandler proxy parameter requires Apache HTTP Server 2.4.10.

I hope that this solution will help you too.
