If Zabbix server could not start, i suggest first looking at /var/log/zabbix/zabbix_server.log
There may be some error message pointing to the problem

Please refer to the comments in the URL below and set up SELinux.

https://support.zabbix.com/browse/ZBX-10542

[netofficer]

already disabled selinux but still the issue is there

[Atsushi]

How did you set it to disabled?
Have you restarted the OS after setting?

Please check the current state of SELinux with getenforce command.

[netofficer]

I check but its again saying enforcing....kindly tell me where to enter the code

[kaspars.mednis]

I think here is everything about disabling SELINUX on Centos

https://www.centos.org/docs/5/html/5.1/Deployment_Guide/sec-sel-enable-disable.html

regards,
Kaspars

[netofficer]

thanks for your reply i disabled it one but still problem was there

[Atsushi]

To temporarily set it to Permissive and make it executable, use the setenforce command.

# setenforce 0

If you want to permanently set it to Disabled, change the SELINUX line in /etc/selinux/config.

SELINUX=disabled

Restarting the OS is necessary to enable this setting.

[netofficer]

i set core dump= no
selinux status permissive
still the server is not running zabbix home page is attached

[Atsushi]

Has the zabbix_server process been started?

# ps -ef|grep zabbix_server

Is something outputted in the log?
(/var/log/zabbix/zabbix_server.log)

If the zabbix_server process is running, did you set firewalld?

[netofficer]

out put of above command
zabbix 2986 1 0 13:12 ? 00:00:00 /usr/sbin/zabbix_server -c /etc/zabbix/zabbix_server.conf
root 3297 2839 0 13:15 pts/0 00:00:00 grep --color=auto zabbix_server

[netofficer]
