6 Web interface installation

This section provides step-by-step instructions for installing Zabbix web interface. Zabbix frontend is written in PHP, so to run it a PHP supported webserver is needed.

To use any other language than English, its locale should be installed on the web server. See the "See also" section in the “User profile” page to find out how to install it if required.

Welcome screen

Open Zabbix frontend URL in a browser. If you have installed Zabbix from packages, the URL is:

  • for Apache: http://<server_ip_or_name>/zabbix
  • for Nginx: http://<server_ip_or_name>

You should see the first screen of the frontend installation wizard.

Providing the webserver user has write access to conf/ directory the configuration file would be saved automatically and it would be possible to proceed to the next step right away.

Finish the installation.
