Install PyroCMS on CentOS 7 in Simple Steps

How to Install PyroCMS on CentOS 7
How to Install PyroCMS on CentOS 7
  PyroCMS is an open source CMS written in PHP. PyroCMS source code is hosted on GitHub. In this tutorial, we will teach you about the entire PyroCMS installation process on a CentOS 7  instance. I have already covered CMS and CentOS 7 in the following tutorial guides;

Requirements

Before you can install PyroCMS on a server, there are a few requirements that need to be met.
  • 1GB of RAM
  • LEMP/LAMP stack
  • PHP >= 7.0
  • PDO PHP Extension
  • cURL PHP Extension
  • SQLite PHP Extension
  • OpenSSL PHP Extension
  • Mbstring PHP Extension
  • Fileinfo PHP Extension
  • Tokenizer PHP Extension
  • GD Library (>=2.0) OR Imagick PHP extension (>=6.5.7)
  Check the 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
 

Install PHP and required extensions

CentOS does not provide the latest PHP version in its default software repositories. You will need to add a ‘Webtatic YUM’ repo. Download and install PHP 7.2 and required PHP extensions.
sudo yum install -y php72w php72w-cli php72w-fpm php72w-mysql php72w-curl php72w-sqlite3 php72w-mbstring php72w-gd php72w-dom
  Check PHP version.
php --version
PHP 7.2.2 (cli) (built: Feb  4 2018 10:14:07) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
 

Install MySQL/MariaDB and create a 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

[mariadb]
name = MariaDB
baseurl = https://yum.mariadb.org/10.2/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1


sudo yum install -y MariaDB-server MariaDB-client
  Check the MariaDB version.
mysql --version
# mysql  Ver 15.1 Distrib 10.2.13-MariaDB, for Linux (x86_64) using readline 5.1
  Start and enable MariaDB.
sudo systemctl enable mariadb.service
sudo systemctl start mariadb.service
  Run the ‘mysql_secure_installation’ script to improve the security of your MariaDB installation.
sudo mysql_secure_installation
  Log into MariaDB as the root user.
mysql -u root -p
# Enter password:   Create a new MariaDB database and user; make sure to remember the credentials.
create database dbname;
grant all on dbname.* to 'username' identified by 'password';
Exit MySQL.
exit
 

Install and configure NGINX

Install NGINX.
sudo vim /etc/yum.repos.d/nginx_mainline.repo

# Copy/paste this to the /etc/yum.repos.d/nginx_mainline.repo file

[nginx]
name=nginx repo
baseurl=https://nginx.org/packages/mainline/centos/7/$basearch/
gpgcheck=1
enabled=1


wget https://nginx.org/keys/nginx_signing.key
sudo rpm --import nginx_signing.key
rm nginx_signing.key

sudo yum install -y nginx
  Check the NGINX version.
nginx -v
  Start and enable NGINX.
sudo systemctl enable nginx.service
sudo systemctl start nginx.service
  Configure NGINX as a FastCGI proxy. Run ‘sudo vim /etc/nginx/conf.d/pyro.conf’ and populate it with the following text.
server {
  listen 80;

  server_name example.com; # Check this
  root /var/www/pyro/public; # Check this

  index index.php index.html;
  charset utf-8;

  location / {
    try_files $uri $uri/ /index.php?$args;
  }

  location ~ \.php$ {
    fastcgi_pass 127.0.0.1:9000; # Check this
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
  }
}
  NOTE: Make sure to point the web root to Pyro’s public directory. Test the NGINX configuration.
sudo nginx -t
  Reload NGINX.
sudo systemctl reload nginx.service
 

Download and install Composer

Download the Composer dependencies.
sudo yum install -y curl git unzip
  Download and install Composer, the dependency manager for PHP.
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === '544e09ee996cdf60ece3804abc52599c22b1f40f4323403c44d44fdfdd586475ca9813a858088ffbc1f233e9b180f061') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
sudo mv composer.phar /usr/local/bin/composer
  Check the Composer version.
composer --version
# Composer version 1.6.3 2018-01-31 16:28:17
 

Download and install PyroCMS via Composer

Create a document root directory.
sudo mkdir -p /var/www/pyro
  Change the ownership of the ‘/var/www/pyro’ directory to ‘johndoe’.
sudo chown -R johndoe:johndoe /var/www/pyro
  Download the latest stable release of PyroCMS from the command line.
cd /var/www/pyro
composer create-project pyrocms/pyrocms .
  NOTE: You may run out of memory when installing Pyro via Composer. It may be wise to stop Nginx, PHP-FPM and MySQL servers with ‘sudo systemctl stop nginx.service php-fpm.service mysql.service’ to save on memory usage and start them again after this step. Change the ownership of the ‘/var/www/pyro’ directory to Nginx.
sudo chown -R nginx:nginx /var/www/pyro
  Run ‘sudo vim /etc/php-fpm.d/www.conf’ and set the user and group to Nginx.
sudo vim /etc/php-fpm.d/www.conf
# user = nginx
# group = nginx
Restart the php-fpm.service.
sudo systemctl restart php-fpm.service
  Using your preferred web browser, open your site and follow the PyroCMS installer. After following the installer you will have PyroCMS up and running. To access the PyroCMS admin area, append ‘/admin’ to your site URL. One more thing.. Share this tutorial guide with your hosting administrators and networking experts , as it will help them and make my countless hours of work count.
