Possible apache conflict when installing ERPNext and Zabbix

[AndRec]

These days I installed Zabbix and ERPnext (in this order) on Ubuntu 14.10 and everything went OK. I followed these instructions: https://www.digitalocean.com/communi...?comment=10261

However, today I had to format the system and I also had to install ERPnext first. But now I can't access Zabbix. When I type myIP/zabbix, I get a message " Page missing or moved" (generated by the ERP stuff).


Here's a part of Zabbix installation that can be useful:

Enabling module mpm_prefork.
apache2_switch_mpm Switch to prefork
* Restarting web server apache2 (98)Address already in use: AH00072: make_sock: could not bind to address [::]:80
(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
AH00015: Unable to open logs
Action 'start' failed.
The Apache error log may have more information.

The logs in /var/log are empty.

What should I do to have both working at the same time?

I managed to fix this problem.

The problem is that nginx and apache were trying to use the same port.
