This article introduces how to set up reverse proxy and load balancing in nginx. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

Reverse proxy; in fact, you can't access it or give it to nginx to return the result of the visit to the client, that is, the browser.

Let me give you another example: as we all know, it is impossible to access Google in China, so how can we access Google? We also thought, can Americans not access Google (this is nonsense, Google is American), if the IP address of the public network of our computer can be changed into the IP address of the United States, then we can access Google.

Server {listen 80; server_name localhost; # charset koi8-r; # access_log logs/host.access.log main # location / {# Note: comment out the location of the original root path. This page jumps to the home page of nginx, because two identical location paths are not allowed, otherwise an error "nginx: [emerg] duplicate location" / "in / usr/local/nginx/conf/nginx.conf:63" # root html; # index index.html index.htm will be reported. #} location / {# Root path proxy_pass http://localhost:8080; # reverse proxy}

}

Load balancing

Http {

# set the mime type, which is defined by the mime.type file

Include / etc/nginx/mime.types

Default_type application/octet-stream

# set log format

Access_log / var/log/nginx/access.log

# omit some of the configuration nodes above

# .

# set the list of servers for load balancer

Upstream mysvr {

# weigth parameter indicates the weight. The higher the weight, the greater the probability of being assigned.

Server 192.168.8.1x:3128 weight=5

# Port 3128 is enabled for Squid on this machine, but squid is not required

Server 192.168.8.2x:80 weight=1

Server 192.168.8.3x:80 weight=6

}

Upstream mysvr2 {

# weigth parameter indicates the weight. The higher the weight, the greater the probability of being assigned.

Server 192.168.8.x:80 weight=1

Server 192.168.8.x:80 weight=6

}

# the first virtual server

Server {

# listen on port 80 of 192.168.8.x

Listen 80

Server_name 192.168.8.x

# load balancing requests for aspx suffixes

Location ~. * .aspx$ {

# define the default site root location of the server

Root / root

# define the name of the index file on the home page

Index index.php index.html index.htm

# request to the list of servers defined by mysvr

Proxy_pass http://mysvr

The following are some configuration of reverse proxies that can be deleted.

Proxy_redirect off

# backend Web servers can obtain users' real IP through X-Forwarded-For

Proxy_set_header Host $host

Proxy_set_header X-Real-IP $remote_addr

Proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

# maximum number of bytes per file that the client is allowed to request

Client_max_body_size 10m

# maximum number of bytes requested by the buffer proxy

Client_body_buffer_size 128k

# connection timeout between nginx and backend server (proxy connection timeout)

Proxy_connect_timeout 90

# response time of back-end server after successful connection (proxy received timeout)

Proxy_read_timeout 90

# set the buffer size for proxy server (nginx) to store account information

Proxy_buffer_size 4k

# proxy_buffers buffer. If the average page size is less than 32k, set it like this.

Proxy_buffers 4 32k

# buffer size under high load (proxy_buffers*2)

Proxy_busy_buffers_size 64k

# set the cache folder size. If it is larger than this value, it will be transferred from the upstream server.

Proxy_temp_file_write_size 64k

}

}

}
