Zabbix server is not running: the information displayed may not be current

Question

So all of a sudden, after a week of using it, I get an error message on my zabbix server gui (http://localhost/zabbix/.)

The error says: Zabbix serve

Answer 1

My problem was caused by having external ip in $ZBX_SERVER setting.

I changed it to localhost instead so that ip was resolved internally,

$sudo nano /etc/zabbix/web/zabbix.conf.php

Changed

$ZBX_SERVER = 'external ip was written here';

to

$ZBX_SERVER = 'localhost';

then

$sudo service zabbix-server restart

Zabbix 3.4 on Ubuntu 14.04.3 LTS

Answer 2

Edit this file: sudo nano /etc/default/zabbix-server

Adjust the START property to yes:

START=yes

Then try to run Zabbix again: sudo service zabbix-server start

Answer 3

Never had the problem until it suddenly appeared once, for me, the solution was to add (uncomment) the following line in /etc/zabbix/zabbix_server.conf

 ListenIP=0.0.0.0

Answer 4

I solved this problem on Ubuntu 18.04 by uninstalling Zabbix and reinstalling it again from scratch.

The initial installation didn't work because I had followed old posts/guides/tutorials, even from Zabbix documentation itself, so these might probably be outdated. So, the trick was to find and follow the most updated guide to Zabbix installation from its docs.

Here are the two links I followed for uninstalling and reinstalling Zabbix:

• How to uninstall Zabbix: https://www.quora.com/How-do-I-uninstall-Zabbix-server-agent-in-Ubuntu
• How to (properly) install Zabbix: https://www.zabbix.com/download?zabbix=4.0&os_distribution=ubuntu&os_version=18.04_bionic&db=postgresql

When installing Zabbix from the link above, your choosen Zabbix Version, OS Distribution, OS Version or Database may be different from the ones I've selected, but following the instructions on this page will probably be also the right way for you to install your chosen Zabbix configuration without getting errors post installation.

Answer 5

I had the same issue.

I forgotten selinux conf, not all is ok:

setsebool -P httpd_can_connect_zabbix on

Answer 6

On RHEL/CentOS/OEL 6

• Check that the firewall is allowing connection to Zabbix Server port which is 10051, as a user with root priv:

  vi /etc/sysconfig/iptables

and add the following lines

-A INPUT -m state --state NEW -m tcp -p tcp --dport 10051 -j ACCEPT

restart iptables

# service iptables restart

If you have disabled IPV6, you need to also edit the hosts file and remove IPV6 line for "localhost"

# vi /etc/hosts

remove or comment out "#" the ipv6 line for localhost

::1                   localhost6.localdomain6   localhost6

restart the zabbix-server and check if the error message is gone.
