Nginx virtual host configuration to host multiple website portals at the same time

Nginx virtual host configuration, hosting multiple website portals at the same time

Nginx is a high-performance web server that can handle high-concurrency requests and provide fast responses. In practical applications, we often need to host multiple website portals, which requires configuring Nginx virtual host. This article will introduce how to configure Nginx virtual host and host multiple website portals at the same time.

First, we need to define multiple server blocks in the Nginx configuration file. Each server block represents a website entrance. The following example can be inserted into the Nginx configuration file:

server {
    listen 80;
    server_name www.example1.com;
    root /var/www/example1;
    index index.html;

    location / {
        try_files $uri $uri/ =404;
    }
}

server {
    listen 80;
    server_name www.example2.com;
    root /var/www/example2;
    index index.html;

    location / {
        try_files $uri $uri/ =404;
    }
}

In the above example, we defined two server blocks, representing the two website entrances www.example1.com and www.example2.com respectively. Each server block contains the listen directive to specify the listening port, the server_name directive to specify the domain name, the root directive to specify the root directory of the website, and the index directive to specify the default homepage file. In the location block, we use the try_files directive to handle the request.

After configuring the above content, save and reload the Nginx configuration file. You can use the following command to verify whether the configuration file is correct:

nginx -t

If there is no error message, it means there is no syntax error in the configuration file. Next, we need to map the domain name to the server’s IP address. This can be achieved by modifying the local hosts file or adding corresponding resolution records in the DNS server. After ensuring domain name resolution, access the corresponding domain name through a browser to see the content of the corresponding website.

At the same time, we can also configure more server blocks to host more website portals as needed. Just refer to the above example, add a new server block in the configuration file and modify it accordingly.

It is worth mentioning that port 80 is used as the listening port in the above example. If you need to use other ports, please modify the port number in the listen command to the corresponding value.

Summary:

By configuring Nginx’s virtual host, we can easily host multiple website portals at the same time. Each website entrance can have its own domain name and root directory, achieving website isolation and independence. Through the sample code provided in this article, we hope to help readers quickly build an environment for multiple website portals and better apply the advantages of Nginx.
