Getting FastCGI working on nginx
I have two files – a modified version of FastCGI_params, and an extra file that contains my configuration directives for .php files.
The second file is simply named php_fastcgi and is located in the same folder as nginx.conf, and is include php_fastcgi;-d anywhere I need PHP support:
# Process PHP files with FastCGI
location ~* \.php$ {
fastcgi_pass unix:/var/run/php-fpm/www-pool.socket;
include /etc/nginx/fastcgi_params;
}As for the fastcgi_params file, it’s slight modification of the default file, included here for simplicity:
fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; # PHP only, required if PHP was built with --enable-force-cgi-redirect fastcgi_param REDIRECT_STATUS 200;
Getting PHP-FPM sessions working
The default path, /var/lib/php/sessions is – by default – owned by root, and group apache, so the nginx user can’t write to it. So we have to change the folder owner and group:
chgrp nginx /var/lib/php mkdir /var/lib/php/session
Alternatively, create a new directory in /tmp, something like /tmp/php-fpm, and make php-fpm the owner of that, and point php-fpm at that directory. (It would also prevent yum ever mucking with permissions on the folder, something which I’m not sure if it was just my imagination, or actually happened…)
