Manage your virtual hosts on apache server easily

May 28th, 2011 No comments

Building up and making all modifications on your server is pretty boring. There is no need to find the sun again and again. I’ve had to go through the process of reconfiguring my virtual hosts for Apache2 several times and i found a pre modified shell script and modified the script according to my needs. This script enables you to create, destroy your virtual host in a second.

you can download the script from here : vhost.txt or;

mkdir ~/bin
cd ~/bin
wget http://samet.kilictas.com/wp-content/uploads/2011/05/vhost.txt
mv vhost.txt vhost
chmod 755 vhost

Now, to invoke the script, type the following:

. ~/bin/vhost

By using this script you can create, destroy a virtual host. In order to create a new host on your server user following command by replacing appreciate values:

vhost create <domain> <admin -email> <host -ip>

The script creates required directories,files as shown below;

Web directories
/www/htdocs/$domain

Web cgi-bin
/www/cgi-bin/$domain

Web logs
/www/logs/$domain/apache2
/www/logs/$domain/apache2/access.log
/www/logs/$domain/apache2/error.log

then builds virtual host config file and enables it right away (enabling is optional), which is placed in following directory

/etc/apache2/sites-available/$domain

After getting done with all these process it simply creates a little info file

/www/$domain/logs/site_info

Great you have created and enabled your virtual host, you may need to destroy a virtual host, here is how;

vhost destroy <domain>

Bash Shell Scripting Tutorial

April 30th, 2010 No comments

Basics
This tutorial assumes that you already know how to log in to your UNIX machine, bring up the bash shell, and run basic commands such as ls and cat. Getting to this point is fairly easy, but unfortunately this is the level that most users stay at indefinitely. This tutorial is intended to help you start to learn the more advanced features of using a shell, and specifically bash, one of the most powerful shells available.

Please note that most of the command themselves are not explained; you can examine their functionality yourself by either reading their man page, or just experimenting with them to see what they do.

Redirection
Normally programs take input from our keyboard, and display the output to our screens. However, these are just the defaults – UNIX has the ability to redirect the input (commonly referred to as stdin, short for standard input) and output (commonly referred to as stdout, short for standard output).

IBM RAD 7.5 on Ubuntu Karmic 32 Bit

December 8th, 2009 No comments

IBM Rational Application Developer
Lets assume you were using ubuntu 9.04 jaunty and now you have upgraded your distribution to 9.10 karmic. Before i get into 9.10 version i had my RAD 7.5 installed and running. Then decided to upgrade my distro. I’ve read an article and futures of karmic distro, that says plenty of packages getting updated. After getting done with upgrade process i tried to run my RAD 7.5 , it was ok for the first time but there were plenty of errors on screen.

First of all when you upgrade your distro, the gcc++ package gets upgareded so libstdc++.so.5 file to libstdc++.so.6 .Unfortunately RAD 7.5 version looks for libstdc++.5.so file on your system. You have to download this file. Download it by using link below;

http://packages.debian.org/stable/base/libstdc++5

Then install this deb package (If you are running on another linux distro you have to place it just next to where your libstdc++.6.so file, you can use “locate libstdc++.so.6″ command to see where your file is). Then copy below bash script and paste it any of your text editor, save it as “run.sh”. From now on, you can use this script to run your RAD 7.5.

#!/bin/bash
export GTK_NATIVE_WINDOWS=1
/where/your/RADis &

After this process your problem should be gone. Have fun.

Linux desktop will wipe out Windows 7

October 15th, 2009 No comments

This month naked marketing muscle once again shows us how it should be done. In the World, Microsoft made it to number one as the most respected and trusted brand, ahead even of Mercedes-Benz. The people have spoken.

Quite an achievement considering Vista bombed and no amount of PR power could persuade the non-OEM consumer otherwise. Now, obviously before it was too late and the Windows brand itself was damaged, Windows 7 has been released. Word is that it is OK, better even than XP.

Thus, the hiatus that may have been the golden Window of Vista opportunity for Linux on the desktop will soon be gone. The power of the ‘brand’ coupled with a product that actually works is hard to stop. If you think that Microsoft has done a number on the Linux netbook using venerable XP and a fat cheque book then just wait for Windows 7 to get into full swing.
