🔧 Setting Up an Apache Server on CentOS 7
With the benefits of Apache on CentOS 7 covered, let’s dive into the details of setting up your server. In this section, we’ll go over the steps you need to take to install and configure your Apache server, including:
Step 1: Install CentOS 7
The first step in setting up your Apache server is to install CentOS 7. There are a few different ways to install CentOS 7, including using the official installation media or using a tool like Vagrant or Docker. Whichever method you choose, be sure to follow the instructions carefully and ensure that your system meets the minimum requirements for CentOS 7.
Step 2: Install Apache
Once CentOS 7 is installed, the next step is to install Apache. Fortunately, this is a straightforward process with CentOS 7’s package manager, yum. Simply open a terminal and type the following command:
Command |
Description |
|---|---|
yum install httpd |
Installs the Apache 2.4 web server |
After the installation is complete, you can start the Apache web server using the following command:
Command |
Description |
|---|---|
systemctl start httpd.service |

Step 3: Configure Apache
With Apache installed, the next step is to configure it for your website. This includes setting up virtual hosts, configuring the document root, and setting up SSL if needed. Here are a few common configuration tasks you might need to perform:
Configuring Virtual Hosts
If you plan on hosting multiple websites on your server, you’ll need to set up virtual hosts. Virtual hosts let you host multiple websites on a single server, each with their own domain name and content. To set up virtual hosts in Apache on CentOS 7, follow these steps:
Step |
Description |
|---|---|
Step 1 |
Create a directory for your website’s content |
Step 2 |
Create a configuration file for your virtual host |
Step 3 |
Add your website’s domain name to the server’s hosts file |
Step 4 |
Enable the virtual host in Apache |
Step 5 |
Restart Apache |
Configuring Document Root
The document root is the directory where your website’s content is stored. By default, Apache on CentOS 7 uses the /var/www/html directory as the document root. However, you can change this if needed. To change the document root in Apache on CentOS 7, follow these steps:
Step |
Description |
|---|---|
Step 1 |
Create a new directory for your website’s content |
Step 2 |
Edit the Apache configuration file |
Step 3 |
Change the DocumentRoot directive to point to the new directory |
Step 4 |
Restart Apache |
Configuring SSL
If your website requires secure connections, you’ll need to set up SSL. SSL (Secure Sockets Layer) is a protocol that encrypts traffic between the client and server, making it more secure. To set up SSL in Apache on CentOS 7, follow these steps:
Step |
Description |
|---|---|
Step 1 |
Create a certificate signing request (CSR) |
Step 2 |
Submit the CSR to a certificate authority (CA) |
Step 3 |
Install the SSL certificate and key on your server |
Step 4 |
Edit the Apache configuration file to enable SSL |
Step 5 |
Restart Apache |
Step 4: Test Your Website
After configuring Apache, you’ll want to test your website to ensure that everything is working correctly. To do this, you can use a web browser to access your website using its domain name or IP address. If everything is working correctly, you should see your website’s content displayed in the browser.
