Prerequiste

I assume that you have a Centos installation.

Installation

You can copy/paste this script and use it to configure automatically your server.

#!/bin/bash
 
########################
#### Install apache ####
########################
 
echo "install httpd"
yum -y install httpd mod_ssl
 
echo "activate httpd at startup"
systemctl enable httpd.service
 
echo "start service"
systemctl start httpd.service
 
 
########################
#### FIREWALL RULES ####
########################
 
echo "add service http (port 80) to firewall"
firewall-cmd --permanent --add-service http
 
echo "add service http (port 443) to firewall"
firewall-cmd --permanent --add-service https
 
echo "reload firewall-cmd"
firewall-cmd --reload
 

That’s all 🙂
