DirectoryIndex fails to serve file to proxy (php-fpm, proxy_fcgi_module)

[PanaColina <panama.hill@xxxxxxxxx>]

When a directory request is received, apache sends only the directory name to the proxy fcgi, not the file name, even though the DirectoryIndex directive is set (and working correctly in a basic config).  A critical problem as http://www.example.com gives "file not found" or "no input file specified" errors.

This seems to be an issue with DirectoryIndex and apache rather than something specific to the proxy module. I am guessing the problem is that DirectoryIndex is bypassed when a proxy is included. I have tried putting "DirectoryIndex index.php" in every possible location, testing with ProxyPass, ProxyPassMatch, and ReWrite rules in various sections (Location, Directory, VirtualHost) -- all tests having same problem.

Testing with apache 2.4, I can always get apache to serve regular files to the proxy, but not the specified DirectoryIndex file (index.htm or index.php). For the root directory, it sends an empty string:

      proxy_fcgi:trace1] [pid 1620:tid 139973627950848] util_script.c(599): [client 186.108.136.84:44199] Status line from script '': 404 Not Found

Testing with minimal httpd.conf:

  ServerRoot "/usr/local/apache"

  Listen 80

  User nobody

  Group staff

  ServerName myserver.com:80

  LoadModule unixd_module modules/mod_unixd.so

  LoadModule authz_core_module modules/mod_authz_core.so

  LoadModule rewrite_module modules/mod_rewrite.so

  LoadModule dir_module modules/mod_dir.so

  LoadModule proxy_module modules/mod_proxy.so

  LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so

  LoadModule log_config_module modules/mod_log_config.so

  DocumentRoot /usr/local/apache/www/

  DirectoryIndex index.php

   <Location / >

     ProxyPass fcgi://socket=%2fusr%2flocal%2fphp-fpm%2fvar%2frun%2ffpm-php.sock/usr/local/apache/www/

   </Location>

ErrorLog "|/usr/bin/cronolog /usr/local/apache/logs/lexpert-error.%U-%Y.log"

CustomLog "|/usr/bin/cronolog /usr/local/apache/logs/lexpert.%U-%Y.log" combined

LogLevel trace2

I have tried with the standard fcgi://127.0.0.1:9000/usr/local/apache/www/$1 as well. I started off using the basic instructions at http://wiki.apache.org/httpd/PHP-FPM. (Currently testing with php-5.4.7)

Every test has had the same problem with DirectoryIndex.

Any suggestions appreciated.

Thanks in advance,
