How to Install Apache on CentOS 7

How to Install Apache on CentOS 7

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. 

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
