Cant install zabbix from packages

[FildaSmile]

Hello,

i was working on zabbix few months ago and now im back into this bussines.

I just wanted try to install fresh zabbix and refresh the installation steps.

But i have problem, when i want install zabbix 5 on Ubuntu server 20.04 LTS i just stuck on step 3.

c. Create initial database


documentation
Run the following on your database host.
# sudo -u postgres createuser --pwprompt zabbix
# sudo -u postgres createdb -O zabbix zabbix

the result is:

root@zabbix:~# sudo -u postgres createuser --pwprompt zabbix
sudo: unknown user: postgres
sudo: unable to initialize policy plugin

when i try it without root (which make sense when i using sudo) result is:

zabbix@zabbix:~$ sudo -u postgres createuser --pwprompt zabbix
sudo: unknown user: postgres
sudo: unable to initialize policy plugin
zabbix@zabbix:~$

Same story with MariaDB, same story with zabbix 4

Any ideas ?

zabbix@zabbix:~$ sudo -u postgres createuser --pwprompt zabbix
sudo: unknown user: postgres

The "sudo: unknown user: postgres" is happening because there is no postgres user (in /etc/passwd or whatever information store you use as the source of information for authentication) on your Ubuntu server.

Typically the postgres user is created when the database-related packages are installed on the system. You apparently haven't installed any of the PostgreSQL packages.

Yes finally i figured it out by installing postgres server additionally.

Last time when i installed zabbix, the database was included in the installation commands like, now the command saying -> # apt install zabbix-server-pgsql zabbix-frontend-php php7.4-pgsql zabbix-apache-conf zabbix-agent, i thought that "zabbix-server-pgsql" should contain database packages (no matter Maria od Postgres).

So in conclusion, nowadays database packages are not included in the installation instructions ?
