Installing LAMP in LINUX

L - LINUX (the OS)  

      A - APACHE ( the Web server )  

             M - MYSQL ( the database management system ) 

                     P - PHP

LAMP can be installed with just one command 

sudo apt-get install lamp-server

  

But if you want to know what exactly is happening, go through the entire post 

Installing Lamp Server components individually

STEP 1 : Installing APACHE

Open the terminal (ctrl+alt+t) and type the below command .

sudo apt-get install apache2 .

(if asked to enter the password , type it and press enter) .

 Now let us check whether apache has been installed successfully .

 Open any web browser and enter http://localhost/ in the address bar .

                                              

                                (you should see the page as in the image below) .

Congrats you have now installed APACHE !

STEP 2 : Installing PHP

Open the terminal (ctrl+alt+t) and type the below command

 sudo apt-get install php5 libapache2-mod-php5

 (you will be asked to enter the password , type it and press enter)

For  PHP to work correctly and be compatible with apache , we need to restart it , it can be done using command

sudo /etc/init.d/apache2 restart

Now let us check whether php has been installed successfully, to do this, type the following command in the terminal

                                                                                      

                                        sudo /var/www/phptesting.php

Type the following line in the phptesting.php file that has been opened

<?php phpinfo(); ?> 

(this will show you a page having the details of PHP as in the image below) 

Congrats you have now installed both APACHE and PHP !!

STEP 3 : Installing MYSQL

 In the terminal (ctrl+alt+t) type the below command

                   sudo apt-get install mysql-server

 (you will be asked to enter the password , type it and press enter) .

 Enter the user name and password  that you wish to use for mysql .

Once done with the installation, you can verify the successful installation by typing the below command .

                    mysql -u <username> -p

Congrats you have now installed APACHE, PHP and MYSQL !!!

As an alternative you can use the below command for quick installation :-)

sudo aptitude install apache2 php5 mysql-server php5-mysql libapache2-mod-php5
