I’ve decided to migrate Vim-Fu.com (WordPress) from Apache to Nginx for a couple of reasons. The first being that it’s hosted on a virtual slice and needs to be as efficient as possible so I can take the extra resources and hand them over to mysql to improve the site’s performance. The second is that we are discussing the implementation Nginx at work so I wanted to familiarize myself with it. What better way than by setting it up and using it.
Googling returned and nice howto from ElasticDog.com, I simply needed to adapt it to Centos. Here is that process:
- rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm
- yum install spawn-fcgi
- yum install nginx
- /usr/bin/spawn-fcgi -a 127.0.0.1 -u nobody -g nobody -p 9000 -f /usr/bin/php-cgi <– this needs to run on startup
In the /etc/nginx/nginx.conf file, replace from the ‘server’ section of the script to the bottom with:
listen your_ip_address:80; # your server's public IP address
server_name www.vim-fu.com; # your domain name
location / {
root /var/www/vim-fu; # absolute path to your WordPress installation
index index.php index.html index.htm;
# this serves static files that exist without running other rewrite tests
if (-f $request_filename) {
expires 30d;
break;
}
# this sends all non-existing file or directory requests to index.php
if (!-e $request_filename) {
rewrite ^(.+)$ /index.php?q=$1 last;
}
}
location ~ \.php$ {
fastcgi_pass localhost:9000; # port where FastCGI processes were spawned
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/vim-fu$fastcgi_script_name; # same path as above
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 $server_protocol;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$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;
# required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
}
}
}
I checked to see if php was built with ‘–enable-force-cgi-redirect’ using:
- php -i | grep force-cgi-redirect
and found that it was enabled at built time.
- chown -R nginx. /var/www/path_to_site
- service httpd stop
- service nginx start
Can you believe how fast and simple that was? I didn’t have to make any other changes. That seems to be the theme of nginx, fast and simple. There is of course a lot more that nginx can do.

I hope you enjoy setting up and using nginx.
