7 Easy Steps To Add Ports 80 And 443 On Apache In Centos

Adding ports 80 and 443 on Apache in CentOS might seem daunting, but it’s a straightforward process that can be accomplished in just seven easy steps. These ports are essential for serving web pages (HTTP and HTTPS), and if you’re running a web server on CentOS, ensuring these ports are correctly configured is crucial. Let’s dive into the steps, tips, and techniques to ensure you can do this effectively and avoid common pitfalls.

Step 1: Connect to Your CentOS Server

The first step is to connect to your CentOS server via SSH. You’ll need your server’s IP address and credentials. You can use an SSH client like PuTTY for Windows or simply your terminal for macOS or Linux.

ssh username@your_server_ip

Step 2: Install Apache

If you haven’t installed Apache yet, you can do so using the following command. This command updates the package database and installs Apache.

sudo yum install httpd -y

Note:

Step 3: Configure Firewall Settings

After you’ve installed Apache, the next step is to ensure that your firewall allows traffic on ports 80 (HTTP) and 443 (HTTPS).

To check the status of your firewall, use:

sudo firewall-cmd --state

To allow traffic on these ports, use the following commands:

sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload

Common Mistake:

It’s easy to forget to reload the firewall settings after making changes. Always remember to execute the --reload command.

Step 4: Start Apache

Now it’s time to start Apache. Use the following command to start the Apache service:

sudo systemctl start httpd

You can also enable Apache to start on boot with:

sudo systemctl enable httpd

Note:

Step 5: Test Your Configuration

At this point, it’s crucial to test your configuration. You can do this by opening a web browser and navigating to your server's IP address (e.g., http://your_server_ip). If everything is working correctly, you should see the Apache test page.

If you are setting up HTTPS, ensure you have an SSL certificate. You can use tools like Let's Encrypt for a free SSL certificate.

Step 6: Configure Virtual Hosts (Optional)

If you plan to host multiple websites on a single server, configuring Virtual Hosts is the way to go. You can create a new configuration file in the /etc/httpd/conf.d/ directory for your site.

For example, to create a configuration file for your domain:

sudo nano /etc/httpd/conf.d/your_domain.conf

Insert the following configuration:

    ServerName your_domain.com
    DocumentRoot /var/www/html

Don’t forget to replace your_domain.com with your actual domain name.

Note:

<p class="pro-note">📝 Pro Tip: Ensure your domain is pointed to your server's IP address for the virtual host to work properly.</p>

Step 7: Restart Apache

After making changes to your configuration, you will need to restart Apache to apply the changes.

sudo systemctl restart httpd

Check if everything is running fine by repeating the test from Step 5.

Troubleshooting Tips

If you encounter any issues, here are a few troubleshooting tips:

• Check Apache Logs: They are usually located at /var/log/httpd/error_log and can provide insights into any issues.
• Firewall Issues: Double-check your firewall settings to ensure ports 80 and 443 are open.
• SELinux Configuration: If SELinux is enforced, it may block connections. You can temporarily set it to permissive mode to troubleshoot using: sudo setenforce 0.
• DNS Propagation: If you’ve recently updated your DNS records, it might take some time for them to propagate.
