Zabbix server is not running

[skritek]

Hello,

Please help. I'm not a Linux expert. After restarting the Linux server on the Zabbix website, I got the message: "Zabbix server is not running". I read a lot of guides to fix this problem but none helped. The server has been running for almost a year without a reboot and Ubuntu has been updated several times in the meantime.
Zabbix 6.2 runs on Ubuntu 22.04.4.
The zabbix-server service is active (exited). It doesn't even create a log file. The zabbix-agent service is running.

Thanks in advance for any suggestions.

Good day Miroslav

sudo systemctl restart zabbix-server
sudo tail -100 /var/log/zabbix/zabbix_server.log

Hello Markku,

thank you for answer. I have tried these commands before. The zabbix-server service is still active (exited). The Zabbix-server starts and immediately stops. Even creating a log file is not enough.

sudo journalctl -u zabbix-server

If the Zabbix log file stays empty, I don't think the service even starts.

The .deb packages published by Zabbix themselves run zabbix_server as a forking daemon, which means that if it immediately exits with a non-zero status (or if systemd fails to execute it at all), systemd should consider it to have failed to start, but if it exists with a zero status, but without forking off any child process, or the child process(es) exit(s) with a zero status, systemd will show it as "active (exited)". But in that case I'd expect it to have written something to its log.

Hallo,

Thanks for both answers.

I did:
sudo systemctl restart zabbix-server
sudo journalctl -u zabbix-server
Result:

Log file is still without update:

So journalctl just shows that the service (apparently 6.4.11, not 6.2, but anyway) has been started, and no output in the log file. Please show the full output of "sudo systemctl status zabbix-server"

What language is "Jun 31"? Surely not the same as "čec 28"? There are no languages where July is abbreviated "Jun", are there? But there are only 30 days in June...
Regardless, are you showing the most recent journal entries?

That "/etc/init.d/zabbix-server; generated" looks strange. I don't use Ubuntu, but it just smells something that was not-Zabbix-provided, and is very different from the config files on Debian.

Since you have an existing installation (and not a newly setup one), you may want to be careful, but I would just make relevant backups, then "sudo apt purge zabbix\*" (to remove any existing packages about Zabbix), and install Zabbix 6.4 from the official Zabbix download page instructions (except the database of course, use the existing settings for it).

Hello Markku,

Thank you for your answer. I assumed a Zabbix fix.
After uninstalling "sudo apt purge zabbix\*" can I use the upgrade steps: "https://www.zabbix.com/documentation/6.4/en/manual/installation/upgrade/packages/debian_ubuntu" ?

Best regards, Miroslav

[Markku]

You need to follow the new install instructions (except to create new Zabbix database) because after purging the packages there aren't any Zabbix packages to upgrade anymore.
