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 :)

Removing file / folder forcefully

In Ubuntu (or any Linux based OS for that matter) have all folders starting with . (period) as hidden.
These folders will not be displayed with run ls command.

If you want to see the hidden files too, use ls -l command.

I was trying to delete one folder containing 2 files (I guess they are worms / virus in windows) Desktop.ini and Folder.htt . I tried deleting it using Delete Button on Keyboard. I also tried Shift+Delete (I know it doesn't matter) but it didn't work.

Finally after googling a little, I found the solution.
Forcefully delete them.

1. Open terminal
2. Go to the folder you wish to delete.
3. Delete all the files in that folder using sudo rm * (enter your root password when prompted).
4. Now go up one directory using cd .. command.
5. Now run sudo rmdir foldername
   

Extracting RAR file on Ubuntu

I recently installed Ubuntu on my machine.
I had Vista earlier. I was fed up of Vista.

This is Ubuntu is awesome. Never gets freezed.

I got some ebooks, I needed urgently, from one of my friends. But it was in .RAR format.

I was wondering if there's any RAR extractor for Linux.

I used to use WinRAR on Windows.

I searched online and found the command to install it on my machine.
It's simple.

Open Terminal (On Ubuntu: Application -> Terminal)
Type: sudo apt-get install rar

and it's done.
