Hi!

Sorry to hear that you're running into issues. It's hard to give you much help without knowing what you are trying to accomplish. It's also hard to answer questions about more than one task at the same time. I'd encourage you to break up your question into smaller chunks with more information about the problems you encounter.

A good place to start debugging you problems is by look at your error logs. If you are using LAMP, run:

tail /var/log/apache2/error.log

Or if you are using LEMP, run:

tail /var/log/nginx/error.log

Sorry for asking many questions at the same time. I will start with my lamp question first. I followed and installed lamp stack with DO instruction, then follow another instruction to install ajenti and phpmyadmin. Everything seems ok, until I try to test the installation by go to web browser and type in my server ip
xxx.xxx.xxx.xxx:8000 for ajenti --> no page was found
and xxx.xxx.xxx.xxx/phpmyadmin --> browser keep downloading a file

I have no idea why that happen. I don't have any firewall set up, no blocking port, etc..

Hi there,

I have a solution for your problem...

First of all you must install the ajenti from beginning.
https://www.digitalocean.com/community/tutorials/how-to-install-ajenti-control-panel-on-ubuntu-13-04

When you log in to agent and open web sites.
Ajenti ask you to start NGINX ..
do not enable.

After this update apache2, mysql and php5

Cheers
