HOW TO SETUP MULTIPLE DOMAINS AND SUB-DOMAINS IN NGINX

Answer 1

Hi! Today I come to teach you to configure Nginx server to create multiple domains and subdomains in it. This tutorial comes from a question in a comment. Imagine that you have a server on which you want to host multiple sites and projects. Each page will have your domain and, of course, we will not hire a server for each domain. The objective is to configure what is known as virtual machine hosts. The truth is that it is really easy to do this. In Geeky Blogs we have implemented since we have several pages hosted on the same server.

 

The method for adding a domain is the same as for a subdomain, but the latter have to make a simple change: where to put "dominio.com" put "subdominio.dominio.com".

 

STEP 1: INSTALL NGINX

 

Of course, we have installed Nginx. You can follow this tutorial series on setting up a VPS server.

 

STEP 2: CREATE A NEW DIRECTORY

 

The second step in creating a virtual host is add a folder to our system. If we add a dominio.com, do the following:

 

 

1	$ sudo mkdir -p /var/www/dominio.com/public_html   STEP 3: PERMITS

It is necessary and very important to give the correct permissions to the user and group. Being a Web application, give permissions to www-data:

1	$ sudo chown -R www-data:www-data /var/www/dominio.com/public_html

Terminal

 

 

 

 

 

1	$ sudo chown -R www-data:www-data /var/www/dominio.com/public_html

STEP 4: ADD CONTENT

After creating the folder, we need to add the content that will be displayed when the user navigates in the domain. Therefore, we will create a simple index.html file to see if it all works:

 

Terminal

 

 

 

 

 

1	$ sudo nano /var/www/dominio.com/public_html/index.html

 

Now add any HTML code.

 

STEP 5: CREATING THE VIRTUAL HOST NGINX

 

Here we will tell Nginx is going to have a new virtual host to manage, ie when the user enters in the dominio.com browser, the server will need to read the configuration file to create for what to do. In Nginx there are two major routes. The first is sites-available, which contains the configuration files of virtual hosts available on the server. The other is sites-enabled, which contains configuration files enabled sites, ie those operating at the time. We will create a file for dominio.com:

 

Terminal

 

 

 

 

 

1	$ sudo nano /etc/nginx/sites-available/dominio.com

Enter the following content:

server {

        ## Escucha en el puerto 80 (HTTP)

        listen   80;

 

        ## Raíz donde se encuentra la página Web

        root /var/www/dominio.com/public_html;

 

        ## Orden de prioridad de los archivos index

        index index.html index.htm;

 

        server_name dominio.com;

}

 

Despite having created this file, we still can not access our website, because the configuration is in sites-available, but not in sites-enabled. To enable virtual host will create a symbolic link between the two folders:

 

Terminal

 

 

 

 

 

1	$ sudo ln -s /etc/nginx/sites-available/dominio.com /etc/nginx/sites-enabled/dominio.com

STEP 6: RESET NGINX

Unless restart Nginx, the changes will not apply:

Terminal

 

 

 

 

 

1	$ sudo service nginx restart

STEP 7: SETTING THE DNS

Finally we must configure the DNS records. As my server is hosted in DigitalOcean, I will use your panel. To add a subdomain, create a CNAME record with the subdomain name and point to the machine. Something like:
