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

Solution might be this simple:

    sudo su 
    
    nano /etc/zabbix/zabbix-server.conf

Remove "#" in front of DBPassword=YourPassword (will change from blue to grey)

Ctrl x (Y to save and press enter to exit)

    service zabbix-server restart

Now you can refresh your browser running ZABBIX. If not, you will have to do the same steps for CacheSize=32M

You do not have to change anything in /etc/zabbix/web/zabbix.conf.php (localhost is fine)

When editing anything, remember "#" in front of line means invisible to linux.

Answer 2

Maybe is configuration issue

nano /etc/zabbix/zabbix_server.conf

DBHost=localhost

DBName=zabbix_db

DBUser=zabbix_user

DBPassword=XXXXXXX

works for me on Zabbix 3.0 Centos 7

Answer 3

Install nmap (( # yum/apt-get install nmap ))tool and check to find out which port the zabbix is listenning to?(( # nmap -sT -p1-65535 localhost )) 10050 or 10051? The result should be somthing like this:

Starting Nmap 6.40 ( http://nmap.org ) at 2016-11-01 22:54 IRST
Nmap scan report for localhost (127.0.0.1)
Host is up (0.00032s latency).
Other addresses for localhost (not scanned): 127.0.0.1
Not shown: 65530 closed ports
PORT      STATE SERVICE
22/tcp    open  ssh
25/tcp    open  smtp
80/tcp    open  http
3306/tcp  open  mysql
10050/tcp open  unknown    <--- In my case this is it

Then open /etc/zabbix/web/zabbix.conf.php and check the line starting with: $ZBX_SERVER_PORT , it's value should be the same number you saw in the nmap scan result. Change it and restart zabbix-server and httpd and you are good to go!

This may happen because of the old and new IP address I have faced same issue which was solve by below method:

vim /etc/zabbix/web/zabbix.conf.php

$ZBX_SERVER = new ip address

then restart zabbix server
