Recently I got hold of an empty Rackspace server in which we have installed Ubuntu 11.04 Natty Narwhal version. My next step was to setup the LAMP stack in that server to run our PHP site.

First I tried to install XAMPP for Linux. But unfortunately, it failed because XAMPP only supports 32 bit operating system and ours was 64. I didn't want to spend much time on fixing that issue, so I moved to setup the LAMP stack by other means.

Here's what I did (after googling/referring a lot):

## 1.Install lamp-server

1.  **sudo apt-get install tasksel **[installs the tasksel that helps you to install multiple packages as a single task]
2.  **sudo tasksel install lamp-server **[it will install the lamp stack in location */etc/*]
3.  *http://yourdomain.com *should work now.

## 2. Configure PHP Curl module

1.  **sudo apt-get install php5-curl **[downloads and installs curl module]
2.  **sudo /etc/init.d/apache2 restart** [restarts server for the changes to take effect]

## 3. Install phpmyadmin

1.  **sudo apt-get update **[updates the packages repository. When I first tried to install phpmyadmin without updating, it complained that phpmyadmin isn't found.]
2.  **sudo apt-get install phpmyadmin **[will trigger a installation wizard]
3.  Choose **apache2 **for the **server configuration** and choose **no **for **database configuration **(since we have already installed database).
4.  **sudo cp /etc/phpmyadmin/apache.conf /etc/apache2/conf.d **[copies the server configuration so that it is accessible via web]
5.  **sudo /etc/init.d/apache2 restart**
6.  *http://yourdomain.com/phpmyadmin* should work now.

That's it. Now our server is ready for serving the traffic. Place your website files under **/var/www/ **which will be served to the world.


Easy way for setting up the LAMP stack in Ubuntu Linux command line


\*\*In this post, I'm going to explain how you can setup a Java development environment (JDK Eclipse) in Ubuntu. I'm using Ubuntu 10.10, but these steps should be applicable to majority of Ubuntu versions.

Let's start with JDK first.

## Install Sun JDK:

1.  Download the Linux version of latest JDK binary from the [Oracle website][1]. For Java 6, the file name would be: **_jdk-6u22-linux-i586.bin_**
2.  Copy the downloaded JDK file to a directory where you want to install the JDK. I use ***/home//java/*jdk-6u22-linux-i586.bin\*\***
3.  Open terminal window and navigate to the directory where you copied the downloaded file. Then type the command: **\*sudo sh jdk-6u22-linux-i586.bin** \*and press enter.
4.  If it asks for root password, give it and JDK installation will begin. The JDK will be installed on the same directory where the binary is placed.

That's it. JDK installation is done. But we still have one more step to complete. That is, setting up the _JAVA_HOME_ environment variable.

## Setting up JAVA_HOME environment variable:

1.  Go to Nautilus file browser (_Places -> Home Folder_) and open this file: **_'.bashrc'_**. By default this file is hidden. So, press *Ctrl H *which will show all hidden files and then you can see the *.bashrc *file.
2.  Add the below code snippet at the end of the *.bashrc *file:
    export JAVA_HOME=/home//java/jdk1.6.0_22
    PATH=.:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

    **Don't forget to change the path in first line according to where you installed your JDK**

    - That's it. Log off and Log in again for the changes to take effect. To test whether the installation successful, open Terminal and type *java -version *which should show you the currently installed JDK version.

    ## Install Eclipse:

    Installing Eclipse in Ubuntu is pretty simple. Just [download][2] the ZIP file from Eclipse.org and then unzip it. The installation is done. ![;-)][3]

How to setup Java development environment in Ubuntu?


Four months back, I had installed Ubuntu on my laptop and completely forgot about that after the installation. Yesterday, when I tried to install Java and Netbeans IDE on Ubuntu, I had to do some admin works, but I dont remember what password I gave for the 'Ëœroot' user during the installation. So, I thought I forgot the root password and I would have to re-install Ubuntu.

But, when searching on the Internet, I came to know that during the installation, Ubuntu do not ask any password for the root user (but I forgot this!). So, by default the root password is set to blanks. So, now I am happy that I don't need to re-install Ubuntu. ![:)][1]

But to change the root password in Ubuntu, which blanks by default, follow this step:

1.  Open Terminal/Command
2.  Type **sudo passwd**
3.  Ubuntu will ask you for current user password. Type in the current password and press enter.
4.  Now Ubuntu will ask you to enter the new password for the root. Type in the new password, confirm it again and you are done.PS: It is not possible to log-in as a 'Ëœroot' user. I guess this feature is de-activated in Ubuntu.
