Environment Setup for Enterprise Edition

This topic provides a detailed description of the environment setup process for Enterprise Edition of Oro applications.

Before you proceed, please refer to the System Requirements for the complete list of the recommended environmental components and their supported versions. If you are using the same environment and components, as described in the System Requirements, you can reuse the commands provided in this guide without modification. Otherwise, please adjust them to match the syntax supported by the tools of your choice.

Prepare a Server with OS

Get a dedicated physical or virtual server with at least 4Gb RAM with the CentOS v7.4 installed. Ensure that you can run processes as a root user or user with sudo permissions.

Environment Setup

Enable Required Package Repositories

To install the third-party components (like RabbitMQ, Elasticsearch, Redis, etc.) required for OroCommerce Enterprise Edition application operation, use the following repositories:

  • Extra Packages for Enterprise Linux (EPEL) repository by Red Hat
  • Oro Enterprise Linux Packages (OELP) repository by Oro engineers

Note

The necessary installation packages are distributed using the software collections.

Add required repositories to your yum package manager and install the software collections management utils by running:

yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm yum-utils scl-utils centos-release-scl centos-release-scl-rh
yum-config-manager --add-repo http://koji.oro.cloud/rpms/oro-el7.repo

Install Nginx, PostgreSQL, Redis, Elasticsearch, NodeJS, Git, Supervisor, and Wget

Install most of the required Oro application environment components using the following commands:

yum install -y rh-postgresql96 rh-postgresql96-postgresql rh-postgresql96-postgresql-server rh-postgresql96-postgresql-contrib rh-postgresql96-postgresql-syspaths oro-elasticsearch6 oro-elasticsearch6-runtime oro-elasticsearch6-elasticsearch oro-redis4 oro-redis4-runtime oro-redis4-redis oro-rabbitmq-server36 oro-rabbitmq-server36-runtime oro-rabbitmq-server36-rabbitmq-server nginx nodejs npm git bzip2 supervisor

Install PHP

Install PHP 7.1 and the required dependencies using the following command:

yum install -y oro-php71 oro-php71-php-cli oro-php71-php-fpm oro-php71-php-opcache oro-php71-php-mbstring oro-php71-php-mcrypt oro-php71-php-pgsql oro-php71-php-process oro-php71-php-ldap oro-php71-php-gd oro-php71-php-intl oro-php71-php-bcmath oro-php71-php-xml oro-php71-php-soap oro-php71-php-tidy oro-php71-php-zip

Install Composer

Run the commands below, or use another Composer installation process described in the official documentation.

scl enable oro-php71 bash
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" && php composer-setup.php
php -r "unlink('composer-setup.php');"
mv composer.phar /usr/bin/composer

Install Symfony Flex

To improve composer operations performance, install Symfony Flex globally:

composer global require symfony/flex

Environment Configuration

Perform Security Configuration

Configure SELinux

For the production environment, it is strongly recommended to keep SELinux enabled in the enforcing mode.

Warning

The actual SELinux configuration depends on the real production server environment and should be configured by an experienced system administrator.

In this guide, to simplify installation in the local and development environment, we are loosening the SELinux mode by setting the permissive option for the setenforce mode. However, your environment configuration may differ. If that is the case, please adjust the commands that will follow in the next sections to match your configuration.

sed -i 's/SELINUX=enforcing/SELINUX=permissive/g' /etc/selinux/config
setenforce permissive

Configure Users Permissions

For security reasons, we recommend performing all Oro application-related processes on behalf of two different linux users:

  • Administrative user (for example, oroadminuser) — A user should be able to perform administration operations like application installation, update, etc.
  • Application user (for example, nginx) — A user should be able to perform runtime operations that require no changes in the application source code files.

In this guide, to simplify installation in the local and development environment, we are loosening this requirement and use the superuser permissions to perform Oro application administrative tasks. However, for your staging or production environment, please adjust the commands that will follow in the next sections to run environment management commands as well as application install and update via a dedicated admin user.

Commands for running the web server, php-fpm process, cron commands, background processes, etc., are executed via the dedicated application user (nginx). Reuse them without modification, if you keep the same username. Otherwise, adjust them accordingly.

Prepare PostgreSQL Database

Initialize a PostgreSQL Database Cluster

scl enable rh-postgresql96 bash
postgresql-setup --initdb

Enable Password Protected PostgreSQL Authentication

By default, PostgreSQL is configured to use ident authentication.

To use the password-based authentication instead, replace the ident with the md5 in the pg_hba.conf file.

Open the file /var/opt/rh/rh-postgresql96/lib/pgsql/data/pg_hba.conf and change the following strings:

host    all             all             127.0.0.1/32            ident
host    all             all             ::1/128                 ident

to match these ones:

host    all             all             127.0.0.1/32            md5
host    all             all             ::1/128                 md5

Change the Password for the postgres User

To set the password for the postgres user to the new secure one, run the following commands:

systemctl start rh-postgresql96-postgresql
su postgres
psql
\password

Note

You will be prompted to enter the new password.

Create a Database for your Oro Application

To create the oro database that will be used by the Oro application, run the following commands:

CREATE DATABASE oro;
\c oro
CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
\q

Configure Web Server

For the production mode, it is strongly recommend to use the HTTPS protocol for the Oro application public websites, and reserve the HTTP mode for development and testing purposes only.

The samples of Nginx configuration for HTTPS and HTTP mode are provided below. Update the /etc/nginx/conf.d/default.conf file with the content that matches the type of your environment.

Sample nginx Configuration for HTTP Websites (Use in Development and Staging Environment Only)

}
  • Replace <application-root-folder> with the absolute path where you are going to install the Oro application.
  • Replace <your-domain-name> with the configured domain name that would be used for the Oro application.
  • Change ssl_certificate_key and*ssl_certificate* with the actual values of your active SSL certificate.

Optionally, you can enable and configure Apache PageSpeed module for Nginx to improve web page latency as described in the Performance Optimization of the Oro Application Environment article.

Note

If you choose the Apache web server instead of Nginx one, you can find an example of the web server configuration in the Web Server Configuration article.

Configure Domain Name Resolution

If you are going to use your Oro application in the local environment only, modify the /etc/hosts file on the server by adding the following line:

127.0.0.1 localhost <your-domain-name>

After this change, the <your-domain-name> URLs opened in the local environment are handled by the local webserver.

To make your Oro application accessible from the remote locations, configure a DNS server to point your domain name to your server IP address.

Configure PHP

To configure PHP, perform the following changes in the configuration files:

  • In the www.conf file (/etc/php-fpm.d/www.conf) — Change the user and the group for PHP-FPM to nginx and set recommended values for other parameters.

    user = nginx
    group = nginx
    catch_workers_output = yes
    
  • In the php.ini file (/etc/php.ini) — Change the memory limit and cache configuration to the following:

    memory_limit = 1024M
    realpath_cache_size=4096K
    realpath_cache_ttl=600
    
  • In the opcache.ini file (/etc/php.d/10-opcache.ini) — Modify the OPcache parameter to match the following values:

    opcache.enable=1
    opcache.enable_cli=0
    opcache.memory_consumption=512
    opcache.interned_strings_buffer=32
    opcache.max_accelerated_files=32531
    opcache.save_comments=1
    

Configure RabbitMQ

Create RabbitMQ User

systemctl start oro-rabbitmq-server36-rabbitmq-server
scl enable oro-rabbitmq-server36 bash
rabbitmqctl add_user <new_rabbitmq_user> <new_rabbitmq_user_password>
rabbitmqctl set_user_tags <new_rabbitmq_user> administrator
rabbitmqctl set_permissions -p / <new_rabbitmq_user> ".*" ".*" ".*"

Replace <new_rabbitmq_user> and <new_rabbitmq_user_password> with your custom username and password values.

For security reasons, delete the default RabbitMQ user:

rabbitmqctl delete_user guest

Enable Required RabbitMQ Plugins

rabbitmq-plugins enable rabbitmq_delayed_message_exchange

Enable the RabbitMQ WebControl Management Plugin

rabbitmq-plugins enable rabbitmq_management

After this step you can use the Web UI of the RabbitMQ management plugin (http://localhost:15672).
