Installing the database ----------------------- The Zabbix server needs an SQL database to run. As you chose to install this zabbix-server-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 server: -> 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 -> createuser -SDRP zabbix -> createdb -O zabbix 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-server-pgsql/{schema,images,data}.sql.gz \ | psql -h localhost zabbix zabbix See also: https://www.zabbix.com/documentation/6.0/manual/appendix/install/db_scripts
