How To Install OpenCart On CentOS 7 Linux

Today, we will learn how we can install OpenCart on our CentOS 7 Linux distribution.

Why CentOS?

CentOS Linux is a community-supported distribution derived from sources freely provided to the public by Red Hat for Red Hat Enterprise Linux (RHEL). As such, CentOS Linux aims to be functionally compatible with RHEL. The CentOS Project mainly changes packages to remove upstream vendor branding and artwork. CentOS Linux is no-cost and free to redistribute. Each CentOS version is maintained for up to 10 years (by means of security updates — the duration of the support interval by Red Hat has varied over time with respect to Sources released). A new CentOS version is released approximately every 2 years and each CentOS version is periodically updated (roughly every 6 months) to support newer hardware. This results in a secure, low-maintenance, reliable, predictable and reproducible Linux environment.

This will download and install PHP on your CentOS 7 system along with some others PHP modules which are required for OpenCart.

Installing phpMyAdmin

To install phpMyAdmin, issue the below command in the terminal.

sudo yum -y install epel-release

And then issue the below command again.

sudo yum -y install phpmyadmin

Installing OpenCart

Create a folder called opencart and change directory to that opencart folder.

cd opencart

Download the latest OpenCart from here. You need to download a zip archive format file with a name “opencart-2.1.0.2.zip”.

Let’s unzip it by typing the below command on the terminal.

sudo unzip opencart-2.1.0.2.zip

Now, after unzipping the zip archive file, you will get a folder name “opencart-2.1.0.2”. Rename this opencart-2.1.0.2 folder to opencart.

Now, copy this “opencart” folder to the /var/www/html folder path by doing the following.

sudo cp -avr opencart /var/www/html

Now, move to the /var/www/html folder and issue the below two commands.

sudo chmod -R 775 opencart
sudo chown apache:apache opencart

Now change directory to the following directory or folder location.

sudo cd /var/www/html/opencart/upload

cp config-dist.php config.php

We need to rename one more file under admin folder on the following path location. To the file renaming by issuing the below command.
