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.

• 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.

1. Install Apache:
   1. First, clean-up yum:
      sudo yum clean all
   2. As a matter of best practice we’ll update our packages:
      sudo yum -y update
   3. Installing Apache is as simple as running just one command:
      sudo yum -y install httpd
2. Allow Apache Through the Firewall
   1. Allow the default HTTP and HTTPS port, ports 80 and 443, through firewalld:
      sudo firewall-cmd --permanent --add-port=80/tcpsudo firewall-cmd --permanent --add-port=443/tcp
   2. And reload the firewall:
      sudo firewall-cmd --reload

3. Configure Apache to Start on Boot
   1. And then start Apache:
      sudo systemctl start httpd
   2. Be sure that Apache starts at boot:
      sudo systemctl enable httpd
4. Other useful commands for Apache
   1. To check the status of Apache:
      sudo systemctl status httpd
   2. To stop Apache:
      sudo systemctl stop httpd
