Today I tested some tools which should make your life much easier. You know the pain when you work with different kind of Operating Systems (Linux, Mac OS, Windows) and you want to access your files from everywhere. Or it could be even on your smartphone device like iphone, blackberry etc. First of all there is dropbox which works pretty much like an remote folder. You can simply drag files into it and you have 2 GB server storage. Another one I tested and I like very much is evernote. You can even just select some text or picture in your browser and upload it to the server. It will be indexed and you can simply search for your files. There is even a OCR recognition for images. But to use this service you just have 50Mb storage per month and afterwards you need to pay for premium account.

Programs can found be here:

Important: use two “-” before set!

I noticed that each time I restarted my os I didn’t get an IP and I had to start dhclient manually. So how do you get dhclient to start at startup?

Here are the steps you need to do:
1. vi etc/init.d/local

And put following code:

2. Make the file executable

3. Put it into the autostart

The smaller the number is the earlier the file will be executed.

apt-get commands
My source.list for “/etc/apt/source.list”

Update Apt Database

Upgrades Installed Packages

Install Package

Remove Package

Check if there are no broken dependencies

1. Installing Apache Webserver

To test this create a textfile

Put this code in it:

Open your browser and go to: http://ip.address/test.php or http://domain/test.php. Now you should get a generated webpage with all the information about apache/php settings.

2. Enable GD Library with PHP

3. Installing MySQL Database Server

4. Change root password on mysql

5. PhpMyAdmin Installation

The phpmyadmin configuration file is located at: /etc/phpmyadmin folder.
To setup under apache all you need to do is include the following line in /etc/apache2/apache2.conf

Point your browser to: http://domain/phpmyadmin

This is a shortcut of the detailed described installation in:
www.mysql-apache-php.com

du -h –max-depth=1 | sort -n -r

I don’t have a lot of experience in Linux environment but anyway I got the job to install a new webserver at my work. The old server was running on debian already so I decided to take the same linux distribution.

The newest ISO you get from here from here:
www.debian.org

For my installation I just needed the CD1. Because I wanted to try it out first I decided to install debian on VMWare Server. So I booted the ISO file in VMWare and did the standard installation without the GUI. We don’t really need a GUI (Graphic User Interface) for a web server. The installation is actually straight forward.

So now we are logged in as root and are in the command line. So what now???

Follow the instructions on this webpage:
www.mysql-apache-php.com

I actually got some error when I tried to install apache and php with apt-get. To add some more sources to the apt source.list file solved the problem.

To edit the source do following:

You might want to use your own source list. This one worked for me:
