This article introduces the knowledge of "how to make a multi-port website use a Nginx for reverse proxy". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

One: use nginx as a reverse proxy

In order to solve these two problems, the natural first thought is to use reverse proxy, my ideal idea should be like the following picture.

Since all user requests go through nginx, let nginx determine which backend agent the current url needs to jump to, a better strategy should be to let nginx determine what the current host is to decide which webserver to jump to. For example, if a.mip.com jumps to apollo,j.mip.com, it will jump to jenkins. And so on, so it can be solved perfectly, right? In nginx, you can use the if instruction under the rewrite module to judge.

Two: use the if instruction

I would like to mention here that nginx is more primitive, and if you need to use a third-party module, you also need to recompile nginx, which is very troublesome to use, so here simply use OpenResty, which extends nginx, and integrates many mature lua modules to download the latest 1.15.8 by yourself, in exactly the same way as nginx.

The default is to install to the / usr/local/ directory, when you see an openresty directory indicating that you installed successfully.

[root@localhost local] # ls bin etc games include lib lib64 libexec openresty sbin share src [root@localhost local] # pwd / usr/local

Next you can use nginx-v to see the openresty version number or something.

[root@localhost sbin] # pwd / usr/local/openresty/nginx/sbin [root@localhost sbin] # [root@localhost sbin] #. / nginx-v nginx version: openresty/1.15.8.1

For convenience, I just use nginx to open three server:

The first website launched on 192.168.23.129 nginx was proxy.

The second website opened on the 192.168.23.129 8001 nginx, simulating apollo.

The third website opened on 192.168.23.129 8002 nginx, which simulates jenkins.

1. Simulation of apollo

Server {listen 8001; server_name somename alias another.alias; location / {root html; index apollo.html;}}

The default page of the 8001 port website is apollo.html, and the path to this apollo.html is the html directory under nginx, as shown below.

[root@localhost html] # pwd / usr/local/openresty/nginx/html [root@localhost html] # ls 50x.html apollo.html index.html jenkins.html

2. Simulation of jenkins

Server {listen 8002; server_name somename alias another.alias; location / {root html; index jenkins.html;}}

The path of the jenkins.html file is shown above. I won't repeat it.

3. Simulation of proxy

Server {listen 80; server_name localhost; location / {if ($host = "a.mip.com") {proxy_pass http://localhost:8001;} if ($host = "j.mip.com") {proxy_pass http://localhost:8002;}}

As you can see, you only need to use the if conditional statement under the rewrite module to determine the value of the host in the current url by using the $host system variable to jump to the corresponding website.

4. Host mapping

All right, then you just need to map a.mip.com and j.mip.com to the ip address 192.168.23.129 of nginx. Because these domain names are easy to remember rather than real.

192.168.23.129 a.mip.com 192.168.23.129 j.mip.com

5. Start nginx

[root@localhost sbin] #. / nginx [root@localhost sbin] # [root@localhost sbin] # [root@localhost sbin] # netstat-tlnp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 00 0.0.0.0pur8001 0.0.0.0root@localhost sbin * LISTEN 3802/nginx: master tcp 00 0.0.0.0 master tcp 8002 0.0.0.0 LISTEN 3802/nginx: LISTEN 3802/nginx: master tcp 00 0.0.0.0 master tcp 22 0.0.0. 0LISTEN 1172/sshd tcp6 * LISTEN 1172/sshd tcp 0 0 127.0.0.1 LISTEN 1172/sshd tcp6 25 0.0.0.0 * LISTEN 1724/master tcp6 0 0: 22: * LISTEN 1172/sshd tcp6 0 0:: :: * LISTEN 1724/master

As you can see from the picture above, the port 80Query 8001 # 8002 has been opened. Next, you can go to the browser to verify it.

Here are all the nginx.conf.
