Zabbix upgrading from 5.0 to 5.4

[Azat Bolebayev]

Hi all,

Is it possible to upgrade from zabbix version 5.0.4 to 5.4 on CentOS version 7??
We have a postgresql database and nginx web server.
Because when I try to download it for CentOS 7 the PostgreSQL and NGiNX is unavailable.

Yes and no.

The Zabbix developers dropped support for Zabbix Server and Zabbix Web on RHEL7/CentOS7/OL7 at Zabbix 5.2. Their reasoning is that it's too difficult for them to advance the product while supporting older security libraries (like the OpenSSL 1.0.X that's part of CentOS 7). Using the Software Compatilbility Library (SCL) PHP for the web interface was also apparently holding them back? In any case, they don't provide official packages for zabbix-server or zabbix-web for CentOS 7. Their recommendation was that yhou should switch to CentOS 8, but that was before RedHat/IBM changed CentOS 8 from being a respin of RHEL to being something between Fedora and RHEL. Most other open source packages have replaced "CentOS 8" with "Alma Linux 8" or "Rocky Linux 8" on their support list, since those are pure respins of RHEL 8, but I don't know if the Zabbix developers have made a decision on supporting either of those two distros.

If you're stuck with CentOS 7, it is possible to build and package your own Zabbix 5.4 server and web interface for CentOS 7, though it requires some work (you need to provide newer versions of some software, like OpenSSL).

If you want to stick with the vendor packages, though, Zabbix 5.0 LTS is the last version of the server or web package that supports CentOS 7.

The 5.2 and 5.4 agent and agent2 packages do continue to support CentOS 7.

I can't remember whether zabbix-proxy was still supported on CentOS 7 at 5.2 or 5.4 or not, but my guess is not.

See this blog post, especially the later parts, for their reasoning:
