How to Install Nginx on CentOS 7

   

Nginx is a powerful and efficient web server that is widely used to serve web content and as a reverse proxy. In this guide, we will walk you through the steps to install Nginx on a CentOS 7 server using the EPEL (Extra Packages for Enterprise Linux) repository. EPEL provides additional packages that are not included in the default CentOS repositories.

Step 1: Update System Packages

Before installing Nginx, it is recommended to ensure that your system packages are up-to-date. Run the following command to update the package repository and install any available updates:

sudo yum update

This command will update your CentOS system's repository and ensure that you have the latest versions of packages installed.

Step 2: Install EPEL Repository

Next, we need to install the EPEL repository on our CentOS system. This can be done using the following command:

sudo yum install epel-release

Step 3: Install Nginx

Once the EPEL repository is installed, we can proceed to install Nginx using the yum package manager:

sudo yum install nginx

Step 4: Start and Enable Nginx

After the installation is complete, start the Nginx service and enable it to automatically start on boot:

sudo systemctl start nginx
sudo systemctl enable nginx

Step 5: Adjust Firewall Settings If the firewall is enabled on your CentOS system, you'll need to allow traffic on the HTTP and HTTPS ports. You can do this by running the following commands:

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

Step 6: Verify Nginx Installation

To ensure that Nginx has been installed and is running properly, you can use the systemctl command to check its status:

sudo systemctl status nginx

If Nginx is running correctly, you should see output indicating that the service is active and running.

Step 7: Access Nginx Web Server

Finally, open a web browser and enter your server's IP address or domain name in the address bar. If everything is set up correctly, you should see the default Nginx welcome page, indicating that Nginx has been successfully installed on your CentOS 7 server.

Conclusion:

In this tutorial, we have demonstrated how to install Nginx on a CentOS 7 server using the EPEL repository. By following these steps, you can set up a robust and high-performance web server to serve your web content and applications. Nginx offers a wide range of features and can be further configured to meet your specific requirements.
