This article shows you how to fully analyze the process of installing Nginx, the content is concise and easy to understand, it will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

There are tips and tricks to install Nginx. If you have a good grasp of these, you will be able to make better use of the relevant Nginx server. Let's take a look at the introduction to the problems related to installing Nginx. Because the server apache can not resist the current concurrency. After adding the front-end squid configuration.

The problem is still unsolved. And the page program is mostly dynamic. Cannot use fastcgi to process. Therefore, I want to use Nginx as a reverse proxy apache. The whole configuration and installation process is very simple. In the case of high concurrency, some optimizations are made before installation. The current configuration can withstand more than 3000 concurrency. It doesn't seem very big, huh? Heh ~ ~ but enough ~ ~ only there are a few 499 questions.. I expect someone to discuss and solve the problem with me.

Install Nginx process

1 set up users and groups

/ usr/sbin/groupadd www

/ usr/sbin/useradd-g www www

2 install pcre to make it convenient to install Nginx to support rewrite for future needs

Wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.8.tar.gz

Tar zxvf pcre-7.8.tar.gz

Cd pcre-7.8/

. / configure

Make & & make install

3 install Nginx

Wget http://sysoev.ru/ nginx / nginx-0.7.58.tar.gz

Tar zxvf nginx-0.7.58.tar.gz

Cd nginx-0.7.58/

. / configure-- user=www-- group=www-- prefix=/usr/local/

Webserver/nginx-with-http_stub_status_module

-with-http_ssl_module-with-cc-opt='-O2'

-- with-cpu-opt=opteron

Make & & make install

Note the above-- with-cc-opt='-O2'-- with-cpu-opt=opteron, which is compiler optimization, and currently the most commonly used is-02 instead of 3. 0. For the corresponding CPU model, please see: http://wiki.gentoo.tw/index.php/HOWTO_CFLAG

Configuration and optimization profile

Nginx.conf profile:

# Specifies the value for maximum file descriptors that

Can be opened by this process.

Tcp_nopush on

The parameter keepalive_timeout 120; # was enlarged to resolve the 502 error when acting as an agent.

Tcp_nodelay on

Include vhosts/upstream.conf

Include vhosts/bbs.linuxtone.conf

}
