How To Add Domain In Nginx

Introduction To Nginx

Nginx (Internet Information Server) is a popular open-source web server that is able to serve a variety of content, from simple static pages to more dynamic web applications. It is commonly used as a web server for hosting websites, as a load-balancer for distributed web applications, and as an application reverse proxy. Nginx is also known for its ability to handle a large number of concurrent connections with its asynchronous event-driven architecture.

In this guide, we will discuss how to configure the Nginx domain for a website or application. We will cover how to add and remove domains, add virtual host records, and configure name-based virtual hosting. By the end of this guide, you should be able to confidently add and remove domains from your Nginx server.

Adding a New Domain in Nginx

Adding a new domain to Nginx is a relatively straightforward process. It involves defining the domain name in the Nginx configuration file and configuring any necessary parameters associated with the domain. This section covers the steps required to add a new domain to an Nginx webserver.

To begin, open the Nginx configuration file in a text editor. On Linux systems, this is typically located in /etc/nginx/nginx.conf. On Windows systems, the file is typically located in C:nginxconfnginx.conf. In this file, you will need to define the domain name and any related parameters.

First, you will need to add a server block for the domain. A server block is a section of code dedicated to configuring a particular domain. Within this block, you can define the domain name, the IP address used to access the domain, the root directory, error log files, and other settings related to the domain. For example, the following block will define a domain called “example.com”:

“`
server {
listen 80;
server_name example.com;
root /var/www/example.com;
access_log /var/log/nginx/example.com.access.log;
error_log /var/log/nginx/example.com.error.log;
}
“`

Within this server block, you can also configure any desired parameters for the domain. For instance, you can configure rewrite rules, set a web index page, and enable encryption for secure connections. After all desired settings have been configured, save and close the file.

Next, create the directory where the domain’s files will be stored. Since it was specified in the server block above, the directory should be located at /var/www/example.com. Create the directory and copy any necessary files for the domain into it, then set the correct permissions on the directory so that it can be accessed by Nginx and other users.

Finally, you will need to reload Nginx for the changes to take effect. On Ubuntu systems, this can be done using the command sudo nginx -s reload. On CentOS systems, you can use the command sudo systemctl reload nginx. This will reload the Nginx configuration and apply any changes, making the new domain accessible on the web.

Removing a Domain from Nginx

Removing a domain from Nginx is a fairly simple process. It involves removing the domain’s server block from the Nginx configuration file and deleting its associated directory. This section covers the steps required to remove a domain from your Nginx server.

First, open the Nginx configuration file in a text editor. On Linux systems, this is typically located in /etc/nginx/nginx.conf. On Windows systems, the file is typically located in C:nginxconfnginx.conf. In this file, locate the server block associated with the domain and delete it.

Next, delete the directory associated with the domain. This is the directory defined in the server block for the domain. For our example domain, it would be located at /var/www/example.com. Use the command rm -rf to delete the directory and its contents.

Finally, you will need to reload Nginx for the changes to take effect. On Ubuntu systems, this can be done using the command sudo nginx -s reload. On CentOS systems, you can use the command sudo systemctl reload nginx. This will reload the Nginx configuration and remove the domain from the server.

Configuring Name-Based Virtual Hosts in Nginx

Name-based virtual hosting is a way of hosting multiple domain names on a single web server. In name-based virtual hosting, each domain name is associated with a particular website or application and each request for the domain is directed to the associated website or application. This allows multiple domains to be hosted on a single web server and helps save on resources such as memory and disk space.

To enable name-based virtual hosting on Nginx, you will need to add a virtual host record to the Nginx configuration file. This record will define the domain name and associated parameters for the domain. For example, the following record will define a domain called “example.com”:

“`
server {
server_name example.com;
root /var/www/example.com;
access_log /var/log/nginx/example.com.access.log;
error_log /var/log/nginx/example.com.error.log;
}
“`

For each domain that you wish to host, you will need to add a separate virtual host record to the configuration file. In addition, you may also want to configure other settings related to the domain such as rewrite rules, a web index page, and SSL certificates for secure connections.

Once all the desired virtual host records have been added to the configuration file, save and close the file. Then, reload Nginx for the changes to take effect. On Ubuntu systems, this can be done using the command sudo nginx -s reload. On CentOS systems, you can use the command sudo systemctl reload nginx. This will reload the Nginx configuration and enable name-based virtual hosting on the server.

Conclusion

Adding and removing domains from your Nginx server is a relatively straightforward process. We have discussed how to add and remove domains, add virtual host records, and enable name-based virtual hosting. With the steps outlined in this guide, you should be able to confidently configure domains on your Nginx server.
