Apache server works randomly (Ubuntu 12.04 LAMP)

Hi

Today I installed apache, php, mysql on a VPS (ubuntu 12.04).
I already connected one of my domains to the ip of my VPS.
But when I navigate to my domain, I see sometimes this:

OK (the content that should be displayed)

but when I refresh or wait a few minutes I see this content:

It works!

This is the default web page for this server.

The web server software is running but no content has been added, yet.

It's very randomly, it's like apache doesn't know what directory to choose.

Does anyone recognize this problem?

Thanks in advance

Bram

EDIT:

the commands I used after virtual machine installation are:

adduser bram
passwd bram
sudo apt-get update
sudo apt-get upgrade --show-upgraded
sudo apt-get install apache2 apache2-doc apache2-utils
sudo apt-get install libapache2-mod-php5 php5
sudo apt-get install php-pear php5-xcache php5-suhosin
sudo apt-get install php5-mysql
a2dissite default
service apache2 reload
cd /etc/apache2/sites-available
nano mydomain.com
<VirtualHost *:80>
ServerAdmin webmaster@mydomain.com
ServerName mydomain.com
ServerAlias www.mydomain.com
DirectoryIndex index.php index.html
DocumentRoot /var/www/mydomain.com/public_html
ErrorLog /var/www/mydomain.com/logs/error.log
CustomLog /var/www/mydomain.com/logs/access.log combined
</VirtualHost>
mkdir -p /var/www/mydomain.com/public_html
mkdir /var/www/mydomain.com/logs
a2ensite mydomain.com
service apache2 restart

You are saying that you "connected" the server with the domain name.... you mean you set up dns? Are you completely sure dns is resolving the name to the right IP? Perhaps it's resolving to another IP (server with the default apache message) and that's why the response is not the expected one.

Perhaps a little fun with a sniffer to make sure the server you think is responding is the actual server that is responding?

Yes absolutely, I have the same problem when I use my IP as url, so it can't be the problem.

And every single time you are requesting exactly the same URI, right? Then it's either something fancy in the apache config or a bug.

theBram · 11-02-2012, 04:56 PM

Yes, exactly the same URI. It changes every +- 3 to 5 minutes to working (php file with echo "ok") /not working

Could It have something to do with the network adapters?

I could not get your question wright .I Guess php is not working,if that the case you have done all installation&php wright,check whether you have enable php5 module

sudo a2enmod php5
sudo apache2ctl -M -->check whether php5 module is included

Have you placed all static content to the following path to make apache to listen the static content .DocumentRoot /var/www/mydomain.com/public_html

It has nothing to do with php, I think it's a problem with the hypervisor, when I shutdown my virtual machine, my IP/domain still responds, but only with the 'it works' page, so I think my hosting provider did something wrong with the network adapters. (two virtual machines connected to one IP, I think a deleted virtual machine is still active but not visible)

Told you to use one sniffer.
