windows/ubuntu using nignx for load Balancing

First, the implementation of Ubuntu

1, first install nginx server sudo apt-get install nginx

2, cd/etc/nginx/

Sudo Vim Sites-avaliables/default

①, add outside the server node:

Upstream Server_pool {

Server 192.168.0.88:80 weight=4 max_fails=2 fail_timeout=30s;

Server 192.168.0.89:80 weight=2 max_fails=2 fail_timeout=30s;

}

#HTTP Load Balancer module. upstream This field to set up a group of servers, you can put this field in the

As a separate entity in the Proxy_pass and fastcgi_pass directives, they can be servers that listen to different ports, and

It can also be a server that listens to both TCP and Unix sockets . The server can specify a different weight, which defaults to 1.

②, modifying the server node

server {

... ...

Location/{

Proxy_pass http://server_pool/;

# Determine the URL, port, or socketthat needs to be proxied .

Proxy_redirect off;

# If you need to modify the "location" and "Refresh" fields from the reply headers that came from the backend server , you can use this command

Set up.

Proxy_set_header X-real-ip $remote _addr;

# This directive allows you to redefine or add some fields to the request headers sent to the backend server. This value can be a literal, a variable, or a combination of them.

Proxy_set_header x-forwarded-for $proxy _add_x_forwarded_for;

Proxy_set_header Host $host;

Proxy_next_upstream Error timeout Invalid_header http_500 http_502 http_503

http_504 http_404;

# determine under what circumstances the request will be forwarded to the next server:

#error-an error occurred while connecting to a server, sending a request, or reading an answer.

#timeout- A timeout occurred while connecting to the server, forwarding a request, or reading an answer.

#invalid_header-The server returned an empty or incorrect answer.

#http_500-The server returns the code.

#http_502-The server returns the 502 code.

#http_503-The server returns the 503 code.

#http_504-The server returns the 504 code.

#http_404-The server returns the 404 code.

#off- disables forwarding of requests to the next server.

}

③, restart nginx Server

Sudo Service Nginx Restart

Virtual Host Configuration: Configure http://root.com Virtual host

①,sudo cp/ect/nginx/sites-avaliables/default/etc/nginx/sites-avliables/root

②,sudo vim etc/nginx/sites-avliables/root

③, modifying the server node

/etc/nginx/nginx.conf

server {

Listen 80;

Root 80.com;

}

server {

Listen 8080;

Root 8080.com;

}

Apache Configure virtual Host: Configure http://root.com Virtual host

①,sudo cp/ect/nginx/sites-avaliable/default/etc/nginx/sites-avliable/root

②,sudo vim etc/nginx/sites-avliables/root

③, modifying configuration
