Installing the database ----------------------- The Zabbix proxy needs an SQL database to run. As you chose to install this zabbix-proxy-pgsql package you apparently want to use a PostgreSQL server as a storage backend. Set up PostgreSQL on any system - you are not forced to run it on the same computer as the Zabbix proxy: -> apt-get install postgresql Create a new database and access user (let's call both "zabbix"). By default on Debian systems you need to change to the "postgres" user: -> su - postgres -> createdb zabbix -> createuser -SDRP zabbix (You will get asked to enter a password for that new user account.) Then send the necessary SQL files to the database to create the required database schema: -> zcat /usr/share/zabbix-proxy-pgsql/schema.sql.gz \ | psql zabbix zabbix See also: https://www.zabbix.com/documentation/6.0/manual/appendix/install/db_scripts
