Broken file serving under Apache and PHP-FPM via mod_proxy_fcgi, when the filename is not only plain ASCII or w/ blank spaces

(difficulty: moderate, requires system administration expertise to deploy PHP under Apache via PHP-FPM with mod_proxy _fcgi using CentOS 7 and/or Ubuntu 14.04) Prerequisites NB: This worked on Trisquel 7.0, I assume it should also work on Debian/Ubuntu Install the php5-fpm package: apt-get install php5-fpm Enable apache modules: a2enmod proxy_fcgi Edit /etc/php5/fpm/pool.d/www.conf: change listen = /var/run/php5-fpm.sock to listen = 127.0.0.1:9000 uncomment listen.allowed_clients and make sure it is: listen.allowed_clients = 127.0.0.1 Restart php5-fpm: service php5-fpm restart Set up a virtual host with a config like this: <VirtualHost *:80> ServerName stable_master_fcgi.local ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/full/path/to/docroot/$1 DirectoryIndex /index.php index.php DocumentRoot /full/path/to/docroot ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> Enable your vhost and add make an info.php file containing <? php phpinfo(); Access your new vhost in a browser and verify that Server API is FPM/FastCGI Access the same URL, info.php , appending slash arguments composed by plain ASCII and UTF-8 encoded characters including "+" and " " chars to verify that SCRIPT_NAME contains the expected PATH_INFO value at the end and PATH_INFO is URL-encoded Testing Publish a resource, e.g. a PNG, whose name is not only plain ASCII text, including blank spaces, in a restricted access course (no guest, no front page) e.g.: filename_UTF 8_en+coded_それが動作するはず.png. The file should be shown to the user (no HTTP 404). [ Regression test ] Execute the testing instructions of MDL-47210 w/o considering the Windows/IIS setting: here, we want to preserve the successful redirect even with UTF-8 based filenames under a bugged mod_proxy_fcgi env.
