YetiForce requirements

Introduction

YetiForce CRM requires a proper web server configuration. It is a key element for the process of installation as well as for the system to be stable. Most professional web servers meet the requirements presented below. However, in case your server does not meet all the requirements, ask your administrator to adjust the configuration and send him a link to this article. If your administrator cannot change the configuration, it might be time to consider upgrading your server.

During the installation process, the system verifies the actual server configuration and shows the elements that are incorrect and require a change in parameters. Please note that the requirements presented below are not general and not for each installation, for more complex systems they should be verified and optimized individually.

danger

The requirements vary depending on the version of YetiForce. Check the requirements for the version you are installing before you begin.

The requirements listed below are applicable for the following version: Latest Stable Version release date

Possible issues

Core server software (LAMP/LEMP)

  • Operating system - Debian, Ubuntu, RedHat, Mint - works on most Linux distributions. We don't recommend the MS Windows operating system as well as MS Windows Server. Our system works well on Windows servers, however, it's not an optimal environment in terms of web applications.

    danger

    Due to security reasons, we recommend running each version of the YetiForce system (PROD and TEST) on a separate/dedicated user of the operating system (preferably on a separate server), e.g. yfprod, yftest. We do not recommend using one operating system user for several applications/websites.

  • Serwer WWW

    • Nginx 1.23 (recommended) - works on earlier versions as well, however, the latest stable versions are recommended. You can also use alternative software as long as it is compatible.

    • Apache 2.4 - works on earlier versions as well (2.1, 2.2, 2.3), however, the latest stable versions are recommended. You can also use alternative software as long as it is compatible.

      danger

      The system does not work with the ModSecurity web server extension

  • Databases

    • MariaDB 10.6 (recommended) - we recommend the latest stable versions. We don't recommend versions older than 10.1.
    • MySQL 5.7, 8.0 - earlier version (5.6) works as well, the latest stable versions are recommended. You can also use alternative software as long as it is compatible.
  • PHP 7.4 (recommended), 8.0, 8.1 (tests pending). The latest stable versions are recommended (eg. 7.4.x).

Database engine requirements (MariaDB/MySQL)

Configuration files eg. /etc/my.cnf, /etc/mysql/my.cnf, /etc/mysql/conf.d/, my.ini

  • SQL_MODE should not contain STRICT_TRANS_TABLE i ONLY_FULL_GROUP_BY
  • ENGINE = InnoDB should be available and enabled by default (disable --skip-innodb)

Webserver

HTTPS & HTTP2 encryption

We recommend encrypting the connection to the server where the system is located. If the connection to the server is not established via HTTPS, the communication can be intercepted or altered by third parties.

Permissions to folders and files

Permissions to folders and files are often the most common source of problems for people who install an application on VPS and dedicated servers. There should be the same owner for all application files and folders.

We recommend the following configuration:

  • files 644 (rw-r--r--)
  • folders 755 (rwxr-xr-x)

The configuration should allow the uploaded files to have full read and write access at the browser level, without changing the file and folder permissions. It is necessary to remember that when the application is running, it also performs various operations such as reading and writing, as well as creating and deleting files. If you don't know how to configure the permissions, ask your administrator to do it and send them a link to this article.

  • Configuration directory config/
  • Application data directory app_data/

Issues with SELinux

danger

Permission issues occur frequently if SELinux is installed on the server and the enforcing mode is enabled. Note the parameters below:

  • httpd_unified
  • httpd_can_network_connect

https://www.nginx.com/blog/using-nginx-plus-with-selinux/

https://docs.nextcloud.com/server/latest/admin_manual/installation/selinux_configuration.html

https://www.getpagespeed.com/server-setup/nginx/nginx-selinux-configuration

sudo setsebool -P httpd_unified 1
sudo setsebool -P httpd_can_network_connect on

End user requirements

  • OS - any OS that supports a web browser
  • Display: 1280 × 800 (recommended)
  • Browser compatible with ES5 (ECMAScript 5), and from YetiForce version 6.3 on ES6 (ECMAScript 6)

Supported browsers

Users should always have the latest version of any browsers they use because only the most recent versions support the newest web technologies. Below is a list of browsers, starting from the one that is the most recommended for YetiForce (Google Chrome) to the least recommended.

  1. Google Chrome, Microsoft Edge
  2. Firefox
  3. Opera, Brave, Vivaldi
  4. Apple Safari
  5. Internet Explorer
  6. Other

Additional configuration using .htaccess

Some servers allow changing the configuration via the .htaccess file. We present some of the examples below.

Apache module

danger

The configuration below works only if Apache (eg. httpd.conf) is set to "AllowOverride Options" or "AllowOverride All"

<IfModule mod_php5.c>
php_flag log_errors On
php_flag display_errors Off
php_value error_log cache/logs/phpError.log
php_value memory_limit 512M
php_flag output_buffering On
php_flag zlib.output_compression Off
php_flag file_uploads On
php_value upload_max_filesize 100M
php_value post_max_size 50M
</IfModule>
## FastCGI module
<IfModule fcgid_module.c>
FcgidIOTimeout 600
FcgidConnectTimeout 600
FcgidBusyTimeout 600
FcgidIdleTimeout 600
</IfModule>
<IfModule mod_fcgid.c>
IdleTimeout 600
ProcessLifeTime 600
IPCConnectTimeout 600
IPCCommTimeout 600
BusyTimeout 600
</IfModule>

Additional configuration using user.ini

You can also quickly change the PHP configuration by creating a user.ini file in the main directory $_SERVER['DOCUMENT_ROOT'], right now it supports CGI/FastCGI. However, be careful because not all parameters can be configured this way (https://www.php.net/manual/en/configuration.changes.modes.php).
