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.

You can find out more about setting up SSL for Zabbix frontend by referring to these best practices.

Welcome screen

Open Zabbix frontend URL in the 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.

Use the Default language drop-down menu to change system default language and continue the installation process in the selected language (optional). For more information, see Installation of additional frontend languages.

Note that setting the language to English (en_US) will also enable the US time/date format in the frontend.

Configure DB connection

Enter details for connecting to the database. Zabbix database must already be created.

If the Database TLS encryption option is checked, then additional fields for configuring the TLS connection to the database appear in the form (MySQL or PostgreSQL only).

If Store credentials in is set to HashiCorp Vault or CyberArk Vault, additional parameters will become available:

for HashiCorp Vault: Vault API endpoint, vault prefix, secret path, and authentication token;

Pre-installation summary

Review a summary of settings.

Install

If installing Zabbix from sources, download the configuration file and place it under conf/ in the webserver HTML documents subdirectory where you copied Zabbix PHP files to.

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.
