How to Add Domain in CentOS 7: A Comprehensive Guide

Are you struggling to add a domain to your CentOS 7 server? Don’t worry; you are not alone. Adding a domain to CentOS 7 is a crucial step in creating a website. However, it can be a complex task, especially for those who are new to web hosting. In this guide, I will walk you through the step-by-step process of adding a domain to CentOS 7.

Introduction

Having a domain name is essential for online business and branding. It is the web address that people use to access your website and communicate with you. CentOS 7 is a popular Linux distribution that is widely used for web hosting. To add a domain to CentOS 7, you need to install and configure Apache web server, assign the domain name to the IP address, and create a virtual host.

Adding a domain to CentOS 7 may seem overwhelming, but it is not as complicated as it seems. With the right guidance, you can do it yourself without the need for a web developer. So, let’s get started and add a domain to your CentOS 7 server.

Understanding CentOS 7 and Domain Names

CentOS 7 is a popular open-source Linux distribution that is widely used for web hosting. It is known for its stability, reliability, and security. CentOS 7 is a server operating system that is based on the Red Hat Enterprise Linux (RHEL) distribution. It is compatible with a wide range of software and applications, making it an ideal choice for web hosting.

Overview of CentOS 7

CentOS 7 is a free, community-supported distribution that is designed for servers. It offers a stable and secure platform for web hosting, database management, and other server applications. CentOS 7 is known for its long-term support and frequent security updates. It is also compatible with a wide range of hardware and software, making it easy to deploy and manage.

Explanation of Domain Names and Their Importance

A domain name is a unique web address that people use to access your website. It is the online identity of your website that helps people identify and remember your brand. Domain names are important for online businesses, as they help build trust and credibility with customers. Having a domain name also makes it easier for people to find your website and communicate with you.

Difference Between Domain Name and Web Hosting

While domain names and web hosting are closely related, they are two separate things. A domain name is the web address that people use to access your website, while web hosting is the service that allows you to store your website files and data on a server. In other words, a domain name is like a street address, while web hosting is like a house where you store your belongings. Without web hosting, your website cannot be accessed online, even if you have a domain name.

Step-by-Step Guide on How to Add Domain in CentOS 7

If you’re ready to add a domain to your CentOS 7 server, follow these simple steps:

Preparation before adding a domain

Before you begin, ensure that you have root access to your CentOS 7 server. You will also need to have a registered domain name and access to your domain registrar’s DNS settings.

Installing Apache Web Server

The first step in adding a domain to CentOS 7 is to install and configure Apache web server. Apache is a popular open-source web server software that is used to serve web pages to users. To install Apache, open a terminal and type the following command:

sudo yum install httpd

Once the installation is complete, start the Apache service and enable it to start automatically on boot:

sudo systemctl start httpd.service
sudo systemctl enable httpd.service

Creating a Virtual Host

After installing Apache, you need to create a virtual host for your domain. A virtual host is a configuration file that tells Apache how to serve the domain’s content. To create a virtual host, create a new configuration file in the /etc/httpd/conf.d directory:

sudo vi /etc/httpd/conf.d/mydomain.com.conf

Add the following configuration to the file, replacing example.com with your domain name:

<VirtualHost *:80>
    ServerName example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/html/example.com/public_html
    ErrorLog /var/www/html/example.com/error.log
    CustomLog /var/www/html/example.com/access.log combined
</VirtualHost>

Save and close the file. Then, create the document root directory and set the correct permissions:

sudo mkdir -p /var/www/html/example.com/public_html
sudo chown -R apache:apache /var/www/html/example.com/public_html
sudo chmod -R 755 /var/www/html/example.com/public_html

Assigning Domain Name to IP Address

Now it’s time to assign the domain name to the IP address of your CentOS 7 server. To do this, log in to your domain registrar’s website and navigate to the DNS settings. Add an A record with the server’s IP address and the domain name you want to use.

Testing the Configuration

To test if everything is working correctly, restart Apache and navigate to your domain name in a web browser. If you see a default Apache page, congratulations! You have successfully added a domain to your CentOS 7 server.

Frequently Asked Questions (FAQ)

Are you still unsure about adding a domain to CentOS 7? Don’t worry; here are some frequently asked questions to help you understand the process better:

What is a domain name server (DNS) and how does it work?

A domain name server (DNS) is a fundamental part of the internet infrastructure. It is responsible for translating domain names into IP addresses, which are used to access websites and other internet services. When you type a domain name in your browser, the DNS server looks up the IP address associated with that domain and returns it to your browser. This process enables your computer to connect to the website’s server and load the webpage.

Can I add multiple domains in CentOS 7?

Yes, you can add multiple domains to CentOS 7. You need to create a new virtual host for each domain and assign each one a unique IP address. This process allows you to host multiple websites on a single server.

How do I transfer a domain to CentOS 7?

To transfer a domain to CentOS 7, you need to update the domain’s DNS records to point to your server’s IP address. You also need to create a virtual host for the domain and configure it to host the website. Once you have done this, you can upload your website’s files to the server, and the domain will be live.

How do I remove a domain from CentOS 7?

To remove a domain from CentOS 7, you need to delete the virtual host configuration file and the website’s files from the server. You also need to remove any DNS records associated with the domain. This process ensures that the domain no longer points to your server and is no longer accessible.

Conclusion

In conclusion, adding a domain to CentOS 7 may seem like a daunting task, but it is an essential step in creating a website. With this comprehensive guide, you can add a domain to your CentOS 7 server with ease. Remember, preparation before adding a domain is crucial.
