Install Apache

Installing Apache in CentOS is pretty straight forward which is known as httpd. Run the following command to install.

sudo yum install httpd

Once the installation is completed, enable and start the Apache service.

sudo systemctl enable httpd
sudo systemctl start httpd

Configure Firewall

If your server is protected by the firewall and you haven’t opened the HTTP and HTTPS ports. Enable them with the following command.

sudo ufw allow http
sudo ufw allow https

Verify Apache Installation

Every process in Apache is managed with the systemctl command. Verify the installation of Apache with the following command.

sudo systemctl status httpd
