How to set up a reverse proxy secondary domain in Nginx

Hey everyone! Today we're going to talk about how to reverse proxy a secondary domain in Nginx. Have you run into this problem as well? Sometimes, we are in the process of building a website and want to have different secondary domains pointing to different servers by using reverse proxy. So, let me take you on a journey to explore this interesting and useful technique!

preliminary

Before we start, we need to get a few things ready. First of all, we need to have a server with Nginx already installed on it. if you haven't installed Nginx yet, don't worry, we'll teach you how to install and configure Nginx from scratch in this article.

Configuring Nginx

Once you've ensured that Nginx is installed correctly and running properly, we can start configuring Nginx to reverse proxy secondary domain names. First, open the Nginx configuration file, usually in /etc/nginx/nginx.conf or /etc/nginx/conf.d/default.conf.

Next, find the server block in the config file that corresponds to the secondary domain name you want to set up the reverse proxy for. If you already have a server block, then add the following code directly into that block:

server {
listen 80; server_name subdomain.yourdomain.com; server_name
server_name subdomain.yourdomain.com; server_name subdomain.yourdomain.com; server_name subdomain.yourdomain.com

location / {
proxy_pass http://your_other_server; }
}
}

Here, you need to replace subdomain.yourdomain.com with the secondary domain name you want to set and your_other_server with the address of the server you want to proxy. You can add more proxy configurations in the location block as needed, such as setting specific path matching, load balancing, etc.

Then, save and exit the configuration file. Next, we need to restart Nginx for the configuration to take effect. Restart Nginx by running the following command:

"`bash
sudo service nginx restart
“`

Verification takes effect

Once everything is set up, we need to verify that the configuration is working. First, make sure that your DNS has correctly resolved the second-level domain name you want to set up and is pointing to that server. Then, visit your secondary domain name in a browser to see if it's successfully reverse-proxied to the server you specified.

If all goes well, you should be able to see what your second-level domain name is pointing to, while the domain name in the URL address bar has not changed. This means that the reverse proxy has worked successfully!

summarize

In this article, we learned how to set up a reverse proxy secondary domain name in Nginx. This is a very practical skill that can help us better manage and use our server resources. By reasonably configuring the reverse proxy, we can easily realize the demand for different secondary domain names pointing to different servers, and improve the flexibility and scalability of the website. I hope this article is helpful to you!
