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

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.
