System Requirements

OroCRM is a web application which runs on a server. Users interact with the application via a web browser on any computer or mobile device that have access to the internet or the network where the server is hosted.

Server-side Requirements

Resources

Resources configuration depends on the data size and number of active users and integrations. Typical setup could be done on a single server with the minimum of 2 CPU cores, 2GB RAM and a fast hard drive (SSD is recommended). The application could scale to multiple servers and a separate database server based on the expected load.

Operating Systems

Linux distributions (RedHat, Ubuntu, Debian, CentOS) are recommended for the production setup. Windows 7 and above and Mac OS X can be used for the development environment.

Software

Oro applications are compatible with most web servers with PHP support, but the following configuration is recommended:

Web Server	Apache 2.2.x or 2.4.x Nginx latest mainline or stable version Web server configuration recommendations are well described in Symfony documentation
PHP	PHP >=7.1.26 version PHP CLI, the same version as for the web server
PHP Settings	Few updates to default PHP configuration settings should be done in php.ini for the web server and CLI: date.timezone must be set detect_unicode must be disabled memory_limit should be 512M or above If the xdebug is installed (which is not recommended in the production setup): xdebug.scream must be disabled xdebug.show_exception_trace must be disabled xdebug.max_nesting_level above 100
PHP Extensions	ctype curl fileinfo gd intl (ICU library 4.4 and above) json mbstring openssl mysql pcre simplexml tokenizer xml zip imap
Database	MySQL 5.7 and above Note Latest version of mariaDB may be used at one's own risk. Oro applications are not tested with mariaDB and thus the correct operation cannot be guaranteed.
Process Control	Supervisor or alternative
Assets	Node.js used for JS assets minification and SCSS assets build.

Note

It is recommended to disable phar PHP extension to reduce the risk of PHP unserialization vulnerability.

Enterprise Edition Software

Enterprise edition is built to support better scale and performance. It is compatible with additional software configuration that allows to achieve these goals.

PHP Extensions	pgsql
Database	PostgreSQL / EnterpriseDB 9.6 and above
Search Index	Elasticsearch 6.0.*
Job Queue	RabbitMQ 3.5.8 and above, with Erlang/OTP version 18.0 and higher. RabbitMQ 3.6.x is recommended

PostgreSQL Configuration

PostgreSQL uuid-ossp extension should be loaded for proper doctrine's guid type handling. In order to enable it, one can connect to the database server and run the following sql query:

CREATE EXTENSION "uuid-ossp";

Optional recommendations

• Tidy PHP extension should be installed to make sure that HTML is correctly converted into a text representation
• Redis - could be used for more efficient application caching. Supported versions of Redis from 2.0 to 3.2
• The performance of :ref:`MySQL can be optimized <mysql-optimization>` by adjusting the configuration

Client-side Requirements

On the client side, Oro applications could be used with most of the graphical browsers on any operating system. Recommended and supported browsers are:

• Mozilla Firefox (latest)
• Google Chrome (latest)
• Microsoft Internet Explorer 11 and above
• Microsoft Edge (latest)
• Safari (latest)
