How to Install Magento on CentOS 7

Magento is a powerful and highly flexible open-source e-Commerce platform (or content management system (CMS)) written in PHP. It ships in two main editions: Enterprise and Community edition. The Community Edition is intended for developers and small businesses.

It is fully customizable to meet users requirements enabling them to setup and manage a fully operational e-Commerce store in minutes. Magento runs on such web servers as Apache, Nginx and IIS, a backend databases: MySQL or MariaDB, Percona.

In this guide, we will show how to install Magento Community Edition on a CentOS 7 VPS with LAMP (Linux, Apache MariaDB and PHP) stack. The same instructions also works on RHEL and Fedora based distributions with slight changes in commands.

Requirements

This article will guide you to install the most recent version of “Community Edition” of Magento on a system running:

1. Apache version 2.2 or 2.4
2. PHP version 5.6 or 7.0.x or later with required extensions
3. MySQL version 5.6 or later

Note: For this setup, I am using website hostname as “magneto-tecmint.com” and IP address is “192.168.0.106“.

Step 1: Installing Apache Web Server

1. Installing Apache web server is so simple, from the official repositories:

# yum install httpd

2. Then, in order to allow access to Apache services from HTTP and HTTPS, we have to open port 80 and 443 where the HTTPD daemon is listening as follows:

------------ On CentOS/RHEL 7 ------------ 
# firewall-cmd --permanent --zone=public --add-service=http
# firewall-cmd --permanent --zone=public --add-service=https
# firewall-cmd --reload

---------- On CentOS/RHEL 6 ----------
# iptables -A INPUT -p tcp -m state --state NEW --dport 80 -j ACCEPT
# iptables -A INPUT -p tcp -m state --state NEW --dport 443 -j ACCEPT
# service iptables save

Step 2: Install PHP Support for Apache

As I said Magento requires PHP 5.6 or 7.0 and default CentOS repository includes PHP 5.4, which is not compatible with latest Magento 2 version.

3. To install PHP 7, you need to add the EPEL and IUS (Inline with Upstream Stable) repository in order to install PHP 7 using yum:

Install PHP 7 on CentOS 7

# yum install -y http://dl.iuscommunity.org/pub/ius/stable/CentOS/7/x86_64/ius-release-1.0-14.ius.centos7.noarch.rpm
# yum -y update
# yum -y install php70u php70u-pdo php70u-mysqlnd php70u-opcache php70u-xml php70u-mcrypt php70u-gd php70u-devel php70u-mysql php70u-intl php70u-mbstring php70u-bcmath php70u-json php70u-iconv

Install PHP 7 on CentOS 6

# yum -y update
# yum -y install epel-release
# wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
# wget https://centos6.iuscommunity.org/ius-release.rpm
# rpm -Uvh ius-release*.rpm
# yum -y update
# yum -y install php70u php70u-pdo php70u-mysqlnd php70u-opcache php70u-xml php70u-mcrypt php70u-gd php70u-devel php70u-mysql php70u-intl php70u-mbstring php70u-bcmath php70u-json php70u-iconv

4. Next, open and modify the following settings in your /etc/php.ini file:

max_input_time = 30
memory_limit= 512M
error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR
error_log = /var/log/php/error.log
date.timezone = Asia/Calcutta

Note: The value for date.timezone will vary as per your systems time zone. Refer to check system timezone and set timezone in Linux.

5. Next, to retrieve a complete info concerning the PHP installation and all its current configurations from a web browser, let’s create a info.php file in the Apache DocumentRoot (/var/www/html) using the following command.

# echo "<?php  phpinfo(); ?>" > /var/www/html/info.php

6. Once all the required configuration completes, its time to start the Apache service and enable it to start automatically from the next system boot as well like so:

------------ On CentOS/RHEL 7 ------------ 
# systemctl start httpd
# systemctl enable httpd

------------ On CentOS/RHEL 6 ------------
# service httpd start
# chkconfig httpd on

7. Next, we can verify that Apache and PHP is working fine; open a remote browser and type your server IP Address using HTTP protocol in the URL and the default Apache2 and PHP info page should appear.

http://server_domain_name_or_IP/
http://server_domain_name_or_IP/info.php

Step 3: Install and Configure MariaDB Database

8. We must note that Red Hat Enterprise Linux/CentOS 7.0 moved from supporting MySQL to MariaDB as the default database management system.

To install MariaDB database, we need to add the following official MariaDB repository to file /etc/yum.repos.d/MariaDB.repo as shown.

Install MariaDB in CentOS 7

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Install MariaDB On RHEL 7

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/rhel7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Install MariaDB in CentOS 6

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Install MariaDB On RHEL 6

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/rhel6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

9. Once the repo file in created, we are now able to install MariaDB as follows:

# yum install mariadb-server mariadb
OR
# yum install MariaDB-server MariaDB-client

10. After the installation of MariaDB packages completes, start the database daemon for the mean time and enable it to start automatically at the next boot.

------------ On CentOS/RHEL 7 ------------ 
# systemctl start mariadb
# systemctl enable mariadb

------------ On CentOS/RHEL 6 ------------
# service mysqld start
# chkconfig mysqld on

11. Then run the mysql_secure_installation script to secure the database (set root password, disable remote root login, remove test database and remove anonymous users) as follows:

# mysql_secure_installation

12. Next create a magento database and user as shown.

# mysql -u root -p

## Creating New User for Magento Database ##
mysql> CREATE USER magento@localhost IDENTIFIED BY "your_password_here";

## Create New Database ##
mysql> create database magento;

## Grant Privileges to Database ##
mysql> GRANT ALL ON magento.* TO magento@localhost;

## FLUSH privileges ##
mysql> FLUSH PRIVILEGES;

## Exit ##
mysql> exit

Step 4: Install Magento Community Edition

12. Now, go the Magento official website, and create a user account in case you a new customer.(or simply login if you already have an account) and download the latest version of Magento Community Edition.

1. http://www.magentocommerce.com/download

13. After you download Magento tar file, extract the contents into the Apache Document Root (/var/www/html) as follows:

# tar -zxvf Magento-CE-2.1.5-2017-02-20-05-36-16.tar.gz -C /var/www/html/

14. Now you need to set Apache ownership to the files and folders.

# chown -R apache:apache /var/www/html/

15. Now open your browser and navigate to the following url, you will be presented with the Magento installation wizard.

http://server_domain_name_or_IP/

16. Next, the wizard will carry a Readiness Check for the correct PHP version, file permissions and compatibility.

17. Enter magento database settings.

18. Magento Web site configuration.

19. Customize your Magento store by setting timezone, currency and language.

20. Create a new Admin account to manage your Magento store.

21. Now click ‘Install Now‘ to continue Magento installation.

That’s it! you have successfully installed Magento in CentOS 7. If you face any errors during installation, feel free to ask for help in the comments..
