Fail to Access Zabbix Web After Installation

[Acho]

Hi good guys,

Can somebody help me please, I have a problem to access Zabbix web / frontend installation after did any script to install Zabbix server on Ubuntu 16.04.
This is the link I refer to install zabbix server :

https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&uact=8&ved=2ahUKEwix-9_z8a7hAhVEJBoKHRrcA5gQFjACegQIChAL&url=https%3A%2F%2Ftecadmin.net%2Finstall-zabbix-on-ubuntu%2F&usg=AOvVaw2LQx5cHRcXtdpx73ttedfJ

But, after installation on ubuntu terminal and intend to continue frontend installation via web to my PC IP:
http://172.16.2.2 -> it shows me apache 'it works!'
and also tried
http://172.16.2.2/zabbix -> it shows me this: 403 Forbidden nginx/1.10.3 (Ubuntu).

What I have done to get some diagnoses is:

I have been trying to do it about last few days but still unable to access this frontend zabbix web installation.
Just FYI, I am just a junior network engineer and not knowing too much about backend and frontend programming.
So if You guys were willing to help me, pls just make it eassy to me

Thanks.

The web server running in your environment seems to be nginx. You will need to either stop nginx and start apache2 or start apache2 on a different port number.

It is possible to run Zabbix by combining nginx and PHP without using apache2, but it may be difficult for beginners.

[kenorosarioPH]

Hi , i am newbie to apache2 and webserver. is there a link i can follow on how to do this?

I already changed my apache2 listening port to 8081 and it redirects me to apache2 default page not the zabbix.

[Atsushi]

Hi kenorosarioPH,
I don't know exactly what you set and how. What I can tell from the phenomenon is that the settings are missing or incorrect, so first check the Apache HTTP Server settings.

Well Mr. Atsushi, it works now. Thanks for your advices.

[Andrey123987456]

Good afternoon everybody, I also have a problem, it’s written in the web interface that the zabbix server is not running, although in fact it is active, please tell me

[Atsushi]

Please check SELinux settings.

[Andrey123987456]

At the moment I have it turned off, but I turned it on and set it up under turned on did not help

This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUX=disabled


setenforce 0

[Andrey123987456]

[root@localhost ~]# getenforce
Disabled

Is this a mistake?

[Andrey123987456]

this is problem ?

[Andrey123987456]

maybe it will help to understand
