Linux-Nginx simple Load Balancing (1), linux-nginx

Here we will perform simple nginx load first, and we will not talk about nginx installation here. We assume that nginx has been installed:

1) check whether the upstrea Server Load balancer module in nginx is installed by default. Go to the nginx source code directory.

./configure --help|grep upstrea 

You can see:

2) Go To The conf directory and filter the configuration file to make it clearer.

egrep -v "#|^$" nginx.conf.default > nginx.conf

3) view the Server Load balancer Module Instructions.

http://nginx.org/en/docs/http/ngx_http_upstream_module.html

4) view the document and find the example:

5) configure the configuration file in vim nginx. conf.

Upstream backend {server 183.2.174.245: 22 max_fails = 3 fail_timeout = 30 s; # ensure that the two ip addresses are accessible to server 121.201.108.43: 22 max_fails = 3 fail_timeout = 30 s; # ensure that these two ip addresses are accessible}

Note:

6) Continue Configuration:

Add to the server label # Use the polling Algorithm for load by default

proxy_pass http://http_backend;

 

7) Restart nginx

8) Round Robin

For n in 'seq 100 '; local ip address of the dorcurl; sleep 2; done

If you use a domain name, go to the host to configure it.

The following describes how to share sessions in Server Load balancer.
