Using Nginx for load balancing

I am currently studying Nginx. As a reverse proxy server, Nginx can accelerate the web server and has load balancing functions.

First, I need to download Nginx from the official website (http://nginx.org/en/download.html). The latest stable version is version 1.0. I have downloaded both the Linux and Windows versions and done it on two servers. Website load balancing.

In the Windows version, decompress the compressed package and execute the command:

1	start nginx

This way you can start the nginx service. And execute the command:

1	nginx -s stop

can stop the service.

This is my IIS server at 192.168.3.82, adding two sites:

Add two files index.html to these two sites respectively, and the contents of the two files respectively display: "This is site 1" , "This is site 2".

Adjust relevant configurations in the nginx.conf configuration file:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

upstream site { server 192.168.3.82:8040; server 192.168.3.82:8041; }} server { listen 8080; server_name 192.168.3.82; #charset koi8-r; #access_log logs/host.access.log main; location /{ root html; index index.html index.htm; proxy_pass http://site; }

;

1

//site

}

1

12

Then save the file That’s it. Then run start nginx once. When you keep refreshing the page, the browser will switch back and forth between the two sites.             You can find that the switching here is to switch back and forth in a 1:1 manner. Through the configuration file, you can know the weight of the site: }

34

upstream site {

​​​server​ 192.168.3.82:8040 weight=2;34

server 192.168.3.82:8041 weight=1; }

weight is the weight of the corresponding website.      In Linux, installing Nginx is more troublesome because some additional packages need to be installed, such as gzip, pcre, etc. For details, please check: http://www.cnblogs.com/yuanermen/archive/2011/03/31/2000993.htmlYou can deploy your site on Linux, such as site 3, if you want to use Windows server as a reverse server To the proxy server, then add a new site in the upstream site:       1} 2

upstream site {
