This article will explain in detail how to configure nginx reverse proxy load balancing cluster under centos7. The content of this article is of high quality, so the editor will share it with you for reference. I hope you will have some understanding of the relevant knowledge after reading this article.

Nginx is a web server, similar to apache, but better and faster than apache. It can also implement reverse proxy and load balancing, which is often used to build load balancing for web service clusters. Today, let's record the installation and configuration of nginx to achieve the role of load balancing.

Experimental environment:

192.168.1.188 nginx load balancer

192.168.1.189 web01 Server

192.168.1.190 web02 Server

Software preparation:

Centos7.4 x86_64

Nginx-1.6.3.tar.gz

Install nginx softwar

Install a collection of dependent package commands

[root@localhost ~] # yum-y install openssl openssl-devel pcre pcre-devel gcc

Install nginx package command collection

[root@localhost ~] # mkdir / app [root@localhost ~] # cd / app [root@localhost ~] # wget-Q http://nginx.org/download/nginx-1.6.3.tar.gz[root@localhost ~] # useradd-s / sbin/nologin-M [root@localhost ~] # tar xf nginx-1.6.3.tar.gz [root@localhost ~] # cd nginx-1.6.3 [root@localhost] #. / configure-- user=nginx-- group=nginx- -prefix=/app/nginx-- with-http_stub_status_module-- with-http_ssl_ module [root @ localhost ~] # make & & make install

Configuration file

(the following is done on web01 and web02)

[root@localhost ~] # vim / app/nginx/conf/nginx.conf

Modify the configuration file to

Worker_processes 1 status events {worker_connections 1024;} http {listen 65 × logarithmic format main'$remote_addr-$remote_user [$time_local] "$request"'$status $body_bytes_sent "http_referer"''"$http_user_agent"$http_x_forwarded_for"; server {listen 80 / serveraccounname bbs.dengchuanghai.org;location / {root html/bbs;index index.html index.htm } access_log logs/access_bbs.log main }} [root@localhost ~] # mkdir / app/nginx/html/bbs [root@localhost ~] # echo "192.168.1.189 bbs" > > / app/nginx/html/bbs/index.html [root@localhost ~] # echo "192.168.1.189 bbs.dengchuanghai.org" > > / etc/hosts [root@localhost ~] # echo "192.168.1.190 bbs" > > / app/nginx/html/bbs/ Index.html [root@localhost ~] # echo "192.168.1.190 bbs.dengchuanghai.org" > > / etc/hosts

(enter the above on two web servers)

Then start nginx separately

[root@localhost ~] # / app/nginx/sbin/nginx-t (check the configuration file for errors) [root@localhost ~] # / app/nginx/sbin/nginx launch [root@localhost ~] # ss-tnlp | grep 80

Use curl bbs.dengch

The following operations are performed on the nginx load balancer

[root@localhost ~] # vim / app/nginx/conf/nginx.conf

Change to the following

Worker_processes 1 server events {worker_connections 1024;} http {include mime.types;default_type application/octet-stream;sendfile on;keepalive_timeout 65 scene upstream www_server_pools {server 192.168.1.190 weight=1;server 80 weight=1;server 192.168.1.189 worker_connections} server {listen 80 weight=1; www.dengchuanghai.org;location / {proxy_pass events ~] # echo "192.168.1.188 www.dengchuanghai,org" > > / etc/hosts

Check the grammar

[root@localhost] # / app/nginx/sbin/nginx-t

Start the service

[root@localhost ~] # / app/nginx/sbin/nginx

Use curl www.dengchuanghai.org

It is found that the output of the result is the rotation of the two servers.

The experiment is over

This is the end of how to configure nginx reverse proxy load balancing cluster under centos7. I hope the above content can be of some help and learn more knowledge. If you think the article is good, you can share it for more people to see.
