Impossible to access web interface installation page [SOLVED]

[darkness4773]

Hi,
It's the first time i have to install CACTI.
I'have followed all the setps from the cacti installation manual but at the end i can't access to the web interface installation page.
Instead of the installation page, i have the config.php file displayed
i have read lot of topics about web interface access issues but none like mine.

I'm using centos7 and mariadb 5.5.68

This is what i have in the browser instead of the web interface page:

Any idea why i'm not able to have the web interface installation page?
I'm a beginner on using Linux and i'm really lost, id don"t understand why i have this.

Thanks for your help.

Wrong server configuration. Install/configure php

[darkness4773]

@macan, thank you for your reply.

I'm sorry, i'm a real beginner in Linux and Cacti.
Can you tell me where to find this file "Install/configure php"?

are you talking about /var/www/html/cacti/cacti-1.2.18/include/config.php?

[cigamit]

It's not a file, he was telling you to install and then configure PHP. There are about a billion guides on the internet on how to do that via Google, even several with Cacti as the example.

[panda72]

could you help me ? Thanks (htpp://myip/cacti) for installation
error.....
Forbidden

You don't have permission to access /cacti/ on this server.

hello,

PHP is installed and configured has asked in the installation manual :https://docs.cacti.net/Install-Under-CentOS_LAMP.md

First, there was wrong information in the config file, i had messages saying wrong path and wrong credentials
After reading several topics, i have amended the config file and now, i have no more message about path and credentials.

so, i don't understand what's is wrong now.

[camerabob]

What is it doing at this point?

[darkness4773]

Hi,
I'm still at the same point.

[camerabob]

The opening URL should be "http://<servername>/cacti". Is that what you're trying?

[darkness4773]

hi camerabob,

yes, this is what i'm trying.

What are the contents of your cacti.conf file located in /etc/cron.d/cacti.conf? Should look something like this:

[root@cb-cacti conf.d]# cat cacti.conf

Your virtual host setting is asking for port 443. Have you tried accessing "https://<servername>/cacti"?

[darkness4773]

hi,

When i try https://<servername>/cacti , i have the error:" this site can't be reached - ERR_CONNECTION_REFUSED

[camerabob]

This looks like more of an Apache issue than cacti.
