CentOS new installation issues

[az0bcd]

Hi All,

I'm having some issues with trying to install Zabbix on CentOS 9 Stream. It's a new installation of CentOS and is up to date.

I've gone along to https://www.zabbix.com/download?zabb...centos&os_vers ion=9&components=server_frontend_agent&db=mysql&ws =apache

and tried to follow the instructions:

[root@localhost az0bcd]# rpm -Uvh https://repo.zabbix.com/zabbix/6.2/r...el9.noarch.rpm

I did manage to get a little bit further by using --nobest etc but things just went from bad to worse.

There are some similar issues reported on the forum but most of those were where the user was installing the wrong version...

[root@localhost az0bcd]# uname -r
5.14.0-160.el9.x86_64
[root@localhost az0bcd]#

Any thoughts?

It looks like you're following the documentation from the download page correctly. When I try the exact same commands on a RHEL 9 test box we have, they work as expected. A bunch of additional packages are added because they are dependencies of the packages you've listed, but they get installed correctly.

The error messages you're receiving, particularly about the conflict with some packages from the 6.0.5 series, makes me suspicious that you may have some older, conflicting packages installed. Are you certain you don't have any zabbix-related packages installed already, perhaps as an earlier attempt? What does

rpm -qa | egrep zabbix

report? Anything?

Thanks for the response.

It was the first attempt, the only other steps I carried out was installing xrdp and mysql.

I've since installed CentOS 8 Stream and followed the instructions without issue. I'm not what you would call a Linux expert but it would appear there are a lot of packages that just aren't available for (9) that are available for (8). So I have stuck to (8) for now.

I'll try again soon.

Thanks.

I'm having the same problem on AlmaLinux 9. Though I was able to install the packages at first, but now running yum update I get:
