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/$1as 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, J.L. Hill [Running on Debian Squeeze]
