Question: My Nginx.conf is Full of Garbage, Do I Need All This and Does It Work?


#1

Hi,

Compared to the clean nginx.conf file you posted in your informative blog post, mine looks like the control center for a spaceship built in an insane asylum. I am running on Ubuntu 11.10, with PHP-FPM, APC, Batcache plugin and APC plugin on Wordpress subdomain multisite, on a test server but sometimes on some subdomains the posts are missing, or work intermittently. Are these rewrite rules correct , your plugin just throws as few warnings but seems to work with them:

}  

and this is the contents of the default file in etc/nginx/sites-enabled/. Strangely I can no logner find the etc/nginx/conf.d/ directory and var/run/nginx.pid is ther but neither a directory nor a file.. maybe symbolic link...

Hi Nasty,

Its really time-consuming to debug/optimize a config like you pasted above. If it works for you then you can continue with it.

Generally speaking, you have added too many things in 1/2 files. You can refactor config by following conventions we use here - http://rtcamp.com/tutorials/wordpress-nginx-setup-conventions/

Refactoring will help you when something will go wrong and you will need to debug things!

Another big issue, I see is you are too many unwanted rules. For example, most of fastcgi_param lines might be present in /etc/nginx/fastcgi_params files. If that file is there, you just need to write include fastcgi_params line in php location-block.

By the way refactoring is different that performance benefits. Refactoring saves human-time. Performance enhancement will save CPU-time and other machine resources. :slight_smile:
