Overview of this book

Nginx is an open source high-performance web server, which has gained quite some popularity recently. Due to its modular architecture and small footprint, it has been the default choice for a lot of smaller Web 2.0 companies for use as a load-balancing proxy server. It supports most of the existing back-end web protocols like FCGI, WSGI, and SCGI. This book is for you if you want to have in-depth knowledge of the Nginx server. Nginx 1 Web Server Implementation Cookbook covers the whole range of techniques that would prove useful for you in setting up a very effective web application with the Nginx web server. It has recipes for lesser-known applications of Nginx like a mail proxy server, streaming of video files, image resizing on the fly, and much more. The first chapter of the book covers the basics that would be useful for anyone who is starting with Nginx. Each recipe is designed to be independent of the others. The book has recipes based on broad areas such as core, logging, rewrites, security, and others. We look at ways to optimize your Nginx setup, setting up your WordPress blog, blocking bots that post spam on your site, setting up monitoring using munin, and much more. Nginx 1 Web Server Implementation Cookbook makes your entry into the Nginx world easy with step-by-step recipes for nearly all the tasks necessary to run your own web application.

Using different logging profiles in the same setup

As we have seen before, Nginx allows you to easily set up a logging format. In this recipe, we will explore how one configuration file can exploit multiple logging formats. This neat functionality can help you generate custom logs specific to a particular section of the site whenever necessary.

How to do it...

This particular configuration will implement three logging formats and then effectively utilize them for logging different sections of the site:

http {

log_format main '$remote_addr - $remote_user [$time_local] '
                '"$request" $status $body_bytes_sent "$http_referer" '
                '"$http_user_agent" "$http_x_forwarded_for"';


# You do not need HTTP authentication information and Refer information for the static files !
log_format static_main '$remote_addr [$time_local] '
                '"$request" $status $body_bytes_sent
                '"$http_user_agent";

# You do not need to know about the bytes sent in an...
