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 server is not running  the information displayed may not be current    Any idea why is this happening ll of a sudden and out of the blue  I restarted the machine - which should automatically restore the zabbix server upon startup - but it s still not running    I also researched for a startup or restart command but true to form with zabbix helpful  clear documentation is non-existent    EDIT    Some more info    MySQL is running normally  I m able to select  insert into  whatever I want    Doing  etc init d zabbix-server status results in    zabbix server is not running  The last entry in zabbix server log is Zabbix Server stopped  Zabbix 2 2 9  revision 52686    Doing sudo  etc init d zabbix-server start results in    Starting Zabbix server zabbix server but the status is still not running and the log file doesn t have any new entries

in my case after installing zabbix from sources (removed zabbix 4.0 because upgrading to 4.2 wasn't possible via apt on a Raspbian GNU/Linux 9.4 stretch) it loaded the config from /usr/local/etc/zabbix_server.conf instead from /etc/zabbix/zabbix_server.conf

After deleting /usr/local/etc/zabbix_server.conf and creating a symlink pointing to the correct config file in /etc/zabbix/zabbix_server.conf it started to work

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

In my case i had to disable Linux SE   root webserverlocaldomain     setenforce 0   Disable Firewall   root webserverlocaldomain     systemctl stop firewalld   Edit config file uncommenting    root webserverlocaldomain     vi  etc zabbix zabbix server conf   ListenPort 10051  DBHost localhost  DBPassword password   Then restart the services    root webserverlocaldomain     systemctl restart zabbix-server zabbix-agent httpd

I was in the same trouble  For my case  that was a conflict between  etc zabbix zabbix agentd conf and zabbix server conf parameters  I adjusted    DBHost localhost     DBName zabbix    DBUser zabbix    DBPassword            DebugLevel 3   ListenPort     If you run the default installation  you should keep ListenPort 10051 for the server and 10050 for the agent   Cheers

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

In my case it happens when introducing host with templates  graphs trigger etc  the server falls  The problem was that by default the cache is at 128k and you have to change it   sudo nano  etc zabbix zabbix-server conf   Uncheck   Sizecache and add 32M for example   Cachesize 32M   restart service and voila   server working  service zabbix-server start

As Zabbix Senior Instructor and Consultant Hernandes Martins says in his  quot Zabbix server is not running what to do  quot  blog post   This is the first step that should be checked regardless of the situation  always view the logs  from the moment the error message appeared in the zabbix web interface always view the log   By following his advice I could be able to identify the cause of the issue with my Zabbix server  and then apply the solution related to the specific problem  In my case  as I ve commented in the page   The problem in my server was of  quot 4  Resource Allocation Issues quot   Just like you wrote above  Zabbix was showing out of memory errors on the log when trying to start the server  After increasing the value of parameter CacheSize I tried to restart the service  but it didn t respond  So  I ended up restarting the whole machine  Fortunately  in the end it resolved the problem for good   So  take a look at the log with command tail -f  var log zabbix zabbix server log on the terminal prompt  watch for any errors  and tackle the problem according to what it makes sense for your particular case

The zabbix-server daemon doesn t seem to like passwords with special characters in them  Unsure whether quotes would work in the configuration I just removed special characters from the database password  updated the configuration files and restarted the daemon   Configuration parsing errors don t show up in logs for some reason

Solution might be this simple      sudo su           nano  etc zabbix zabbix-server conf   Remove  quot   quot  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  quot   quot  in front of line means invisible to linux

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 amp os distribution ubuntu amp os version 18 04 bionic amp 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

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     lt --- 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

Looks like the problem was that I created a Database monitoring Item programmatically and it triggered a bug that caused the server to shutdown    Once I deleted the item the server came back up  and creating subsequent Items didn t kill it    The deadly Item had a value type of Numeric unsigned  -1 programmatically  while the newly created Items have a value type of float  which is 0 programmatically    The whole thing has a voodoo element to it but it did solve my problem
