# How to Install Apache on CentOS

In this article, I’ll explain how to install and manage the Apache webserver on CentOS 8.

# Installing Apache

Apache is available in the default CentOS repositories, and the installation is pretty straight forward.

On RHEL based distributions, the Apache package and service are called httpd. To install the Apache run the following command as root or user with sudo privileges

sudo yum install httpd

Once the installation is complete, enable and start the Apache service

sudo systemctl enable httpd
sudo systemctl start httpd

To verify that the service is running, check its status

sudo systemctl status httpd

# Adjusting the Firewall

FirewallD is the default firewall solution on Centos 8.

During the installation, Apache creates firewalld service files with predefined rules for allowing access to HTTP (80) and HTTPS (443) ports.

The following commands will permanently open the necessary ports

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

# Managing Apache

This section explains how the Apache configuration files are structured and the best practices for managing the Apache webserver.

  • All Apache configuration files are located in the /etc/httpd directory.
  • The main Apache configuration file is /etc/httpd/conf/httpd.conf.
  • Configuration files ending with .conf located in the /etc/httpd/conf.d directory are included in main Apache configuration file.
  • Configuration files that are responsible for loading various Apache modules are located in the /etc/httpd/conf.modules.d directory.
  • You can set your domain document root directory to any location you want. The most common location for webroot is /var/www/html/

Note

It is a good practice to follow a standard naming convention. For example, if the domain name is mydomain.com then the configuration file should be named mydomain.com.conf
