How to Install Apache on CentOS 7


In this article, we will outline the process of installing Apache 2.4 on CentOS 7 Server.

Prerequisites:

  • An up-to-date CentOS 7 Server.
  • A sudo user.

Step 1: Install Apache using YUM

sudo yum install httpd -y

Step 2: Configure Apache

Remove the default Apache welcome page:

sudo cp /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/welcome.conf.baksudo sed -i 's/^/#&/g' /etc/httpd/conf.d/welcome.conf

Prevent Apache from exposing files in visitors’ web browser:

sudo cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.baksudo sed -i "s/Options Indexes FollowSymLinks/Options FollowSymLinks/" /etc/httpd/conf/httpd.conf

Before starting the Apache service, we need to 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

Start the Apache service and set it to auto-start on system boot:

sudo systemctl start httpd.servicesudo systemctl enable httpd.service

The above settings are only basic settings for running an Apache web server. More specific settings can be found in the Apache configuration file /etc/httpd/conf/httpd.conf. You can use the vi text editor to review and edit various settings in that file:

sudo vi /etc/httpd/conf/httpd.conf

After the editing is done, you should restart the Apache service in order to apply your modifications:

sudo systemctl restart httpd.service

That’s it. Thanks for reading.
