Installing / Uninstalling Netbeans

Installing Netbeans in just three steps process

1. Go to http://www.netbeans.org/downloads/start.html
2. Download the package you are looking for.
3. Open Terminal, Go the directory where Netbeans in downloaded and type sh netbeans.sh (whatever is the name of the downloaded file.)

To Uninstall,
Open the terminal, locate the directory where netbeans is installed and run sh uninstall.sh

Simple as that :-)

Command not found

I was trying to uninstall NetBeans from my Linux box. I tried sudo ./uninstall.sh but every time (just to make sure 'm typing everything correctly) it gave me Command Not Found error.

Finally, I found the solution as

chmod a+x uninstall.sh

use SH command.

sh uninstall.sh

This works perfectly. :-)

Removing unwanted files from Ubuntu

Removing unwanted (tmp) files from Ubuntu is very easy.

Open the Terminal window and run: sudo apt-get autoclean

This will delete all the unnecessary files from the computer.

This can fail if Synaptic package manager or any other installation manager is running.

SSH in Ubuntu

When I was using Vista, I used to use Putty / X-Win to SSH to my Server.
But doing that on Ubuntu (or any Linux/Unix box for that matter) is very simple.

Go to Terminal Window.

Run ssh username@hostname/IP address
Enter your password when prompted.

You can exit from SSH using exit command.

That's it.
Isn't it simple?

Note: Though Linux version of Putty is available, using Terminal Window is much simple to use.

Installing MySQL on Ubuntu

Go to Terminal Window and run sudo apt-get install mysql-server libapache2-mod-auth-mysql php5-mysql

You will be asked to enter your ROOT password. The screen looks like this
When the installation is complete, run mysql -u root -p

Enter root password when prompted.
If no error message is displayed, MySQL installation is successful.

Installing PHP5 on Ubuntu

Go to Terminal Window and run sudo apt-get install php5 libapache2-mod-php5

Now restart the Apache Server ( sudo /etc/init.d/apache2 restart )

To test if installation was successful or not, lets create one test file, run the following command. sudo gedit /var/www/test_file.php . This will open up gedit editor. Type . Save the file and close gedit.

Now open your favorite Web Browser and go to the URL http://localhost/test_file.php

You should see something like this.

Installing Apache WebServer on Ubuntu

Hi,
'm coming from Windows background.
I used to use WAMP / XAMPP on windows.

Now I 've switched to Ubuntu and 'm loving it.

I was trying to install Apache WebServer on my machine. I googled a bit and found the solution. I didn't knew installing Apache on Linux could be so easy.

1. Go to Terminal Window.
2. Type sudo apt-get install apache2
3. Enter the root password when prompted.
4. When installed, open your Web Browser and go to URL http://localhost , If it has been properly installed, you should see It Work's!
5. Now try restarting the server, sudo /etc/init.d/apache2 restart . If you receive any error like

   apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
   ... waiting .apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName

6. Run the command gksu gedit /etc/apache2/conf.d/fqdn . This will open up GEdit. Enter the following in it: ServerName localhost
7. Now you should be able to restart your Apache. Try it out :)
