Before you begin

Check CentOS version.

cat /etc/centos-release
# CentOS Linux release 7.4.1708 (Core)

Create a new non-root user account with sudo access and switch to it.

useradd -c "John Doe" johndoe && passwd johndoe
usermod -aG wheel johndoe
su - johndoe

NOTE: Replace ‘johndoe’ with your username.
Set up the timezone.

timedatectl list-timezones
sudo timedatectl set-timezone 'Region/City'

Ensure that your system is up to date.

sudo yum update -y

Install required and useful packages.

sudo yum install -y wget vim unzip bash-completion

Disable SELinux.

sudo setenforce 0


Step 1 – Install PHP and required PHP extensions

CentOS does not provide the latest PHP version in its default software repositories. You will need to add a Webtatic YUM repo.

sudo yum install -y php71w php71w-cli php71w-fpm php71w-mysql php71w-mcrypt php71w-gd php71w-mbstring php71w-json php71w-curl php71w-xml php71w-common

Check the PHP version.

php --version
# PHP 7.1.14 (cli) (built: Feb  4 2018 09:05:29) ( NTS )
# Copyright (c) 1997-2018 The PHP Group
# Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies

Start and enable ‘php-fpm’ service.

sudo systemctl start php-fpm.service
sudo systemctl enable php-fpm.service


Step 2 – Install MariaDB and create database

Download and install MariaDB.

sudo vim /etc/yum.repos.d/MariaDB.repo
# Copy/paste this to the /etc/yum.repos.d/MariaDB.repo file
name = MariaDB
baseurl = https://yum.mariadb.org/10.2/centos7-amd64
sudo yum install -y MariaDB-server MariaDB-client

Check MariaDB version.

mysql --version && mysqld --version
# mysql  Ver 15.1 Distrib 10.2.13-MariaDB, for Linux (x86_64) using readline 5.1
# mysqld  Ver 10.2.13-MariaDB for Linux on x86_64 (MariaDB Server)

Start and enable MariaDB.

sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service

Run the ‘mysql_secure_installation’ script to improve the security of your MariaDB installation.

sudo mysql_secure_installation

Log in to MariaDB as the root user.

mysql -u root -p
# Enter password:
Create a new MariaDB database and user, and remember the credentials.
create database dbname;
grant all on dbname.* to 'username' identified by 'password';
flush privileges;
Exit MySQL.


Step 3 – Install and configure NGINX

Install NGINX server.

sudo yum install -y nginx

Check NGINX version.

sudo nginx -v
# nginx version: nginx/1.12.2

Start and enable NGINX service.

sudo systemctl start nginx.service
sudo systemctl enable nginx.service

Configure NGINX. Run ‘sudo vim /etc/nginx/conf.d/craft.conf’ and copy/paste the following.

server {
  listen [::]:80;
  listen 80;
  server_name example.com;
  root /var/www/craft/public;
  index index.html index.htm index.php;
  charset utf-8;
  location / {
    try_files $uri/index.html $uri $uri/ /index.php?$query_string;
  location ~ [^/]\.php(/|$) {
    try_files $uri $uri/ /index.php?$query_string;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_index index.php;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param PATH_INFO $fastcgi_path_info;
    fastcgi_param HTTP_PROXY "";      

Test the NGINX configuration.

sudo nginx -t

Reload NGINX.

sudo systemctl reload nginx.service


Step 4 – Download and install Craft CMS

Create a document root directory.

sudo mkdir -p /var/www/craft

Change the ownership of the ‘/var/www/craft’ directory to ‘johndoe’.

sudo chown -R johndoe:johndoe /var/www/craft

Navigate to the document root.

cd /var/www/craft

Download the latest stable release of Craft CMS.

wget https://download.craftcdn.com/craft/2.6/2.6.3012/Craft-2.6.3012.zip
Unzip Craft CMS.
unzip Craft-2.6.3012.zip
rm Craft-2.6.3012.zip

Tell Craft how to connect to your database.

vim craft/config/db.php

Change the ownership of the ‘/var/www/scraft’ directory to nginx.

sudo chown -R nginx:nginx /var/www/craft

Run ‘sudo vim /etc/php-fpm.d/www.conf’ and set user and group to nginx. Initially, it will be set to user and group apache.

sudo vim /etc/php-fpm.d/www.conf
# user = nginx
# group = nginx
Restart php-fpm.service.
sudo systemctl restart php-fpm.service

Now that everything’s set up, point your browser to ‘http://example.com/admin’ and follow the Craft installer.
To access Craft’s administrative interface, append ‘/admin’ to your IP/domain.
