Effortlessly Set Up an NGINX Web Server on CentOS 8

Installing NGINX on CentOS 8
In this guide, you will learn how to install, activate, and initiate an NGINX Web Server on CentOS 8, step by step. We will also explore how to automate this entire procedure using a straightforward Bash script.
First, it's essential to verify if there are any pending package updates for your CentOS server. You can do this by executing the following command:
sudo yum check-update
After running this command, you will be prompted to enter your password. Even the most diligent users occasionally forget their passwords or accidentally press the wrong key! Once you check for updates, proceed to install any available updates using:
sudo yum update
After executing the update command, the system will either apply the updates or indicate that no updates are available, as shown by the "Complete" message.
Next, it's time to install NGINX. Use the command below:
sudo dnf install nginx
During the installation process, the system will inform you about the number of packages being installed and ask for your confirmation. Simply type "y" to finalize the installation.
Congratulations! You have successfully installed an NGINX Web Server on CentOS 8. However, there's still some work to do to get it fully operational.
Enabling and Starting NGINX
To enable the server, use the following command:
sudo systemctl enable nginx
Now that the server is enabled, you can start it by running:
sudo systemctl start nginx
Next, you will need to adjust the firewall settings. First, it's a good idea to note your IP address, which you can retrieve with:
curl ifconfig.me
This step is crucial for testing your server later. After that, adjust your firewall settings with the command:
sudo firewall-cmd --permanent --add-service=http
Afterward, list the current firewall settings and reload the firewall using these commands:
sudo firewall-cmd --list-all
sudo firewall-cmd --reload
To check the status of your NGINX server, run:
systemctl status nginx
At this point, you’re ready to test your setup! Copy your public IP address and paste it into your web browser to see if everything is functioning correctly.
Creating a Bash Script for Automation
Now comes the exciting part: automating the entire process with a simple Bash script. Begin by opening your vi editor and creating a new file with:
sudo vi nginx.sh
Enter your password when prompted. Once inside the editor, press "i" to start typing. Input the necessary commands to automate the installation and setup process.
After entering all the commands, save and exit by pressing Esc followed by :wq.
Next, modify the file permissions with:
sudo chmod +x nginx.sh
After entering your password again, execute the script by running:
./nginx.sh
And just like that, the entire setup process is automated with a single command!
