The Apache web server is one of the most popular and powerful web servers in the world, due to its ease of administration and flexibility. In this tutorial we will install Apache on a server that doesn’t have a web server or database server already installed.
Pre-Flight Check
- These instructions are intended for installing Apache on a single CentOS 7 node.
- I’ll be working from a Liquid Web Self Managed CentOS 7 server, and I’ll be logged in as non-root user. If you need more information then visit our tutorial on How to Add a User and Grant Root Privileges on CentOS 7.
Step 1: Install Apache
First, clean-up yum:
sudo yum clean all
As a matter of best practice we’ll update our packages:
sudo yum -y update
Installing Apache is as simple as running just one command:
sudo yum -y install httpd
Step 2: Allow Apache Through the Firewall
Allow the default HTTP and HTTPS port, ports 80 and 443, through firewalld:
sudo firewall-cmd --permanent --add-port=80/tcp
sudo firewall-cmd --permanent --add-port=443/tcp
And reload the firewall:
sudo firewall-cmd --reload
Step 3: Configure Apache to Start on Boot
And then start Apache:
sudo systemctl start httpd
Be sure that Apache starts at boot:
sudo systemctl enable httpd
To check the status of Apache:
sudo systemctl status httpd
To stop Apache:
sudo systemctl stop httpd
