Issues with installation

[Vahan Yeranosyan]

I am following this tutorial in installing netdot https://www.digitalocean.com/community/tutorials/how-to-document-your-network-with-netdot-on-centos-7

But apache refuses to work claiming:

● httpd.service - The Apache HTTP Server
   Loaded: loaded (/usr/lib```
/systemd/system/httpd.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Ср 2021-03-24 21:48:45 +04; 32s `ago`

           man:apachectl(8)

Maybe the problem is with the packages?
