Install LAMP stack on Ubuntu

STEP:1 INSTALL APACHE

Apache is a free open source software that runs over 50% of the world’s web servers.

To install apache, open the terminal and type in these commands:

sudo apt-get update 

sudo apt-get install apache2


STEP:2 INSTALL MYSQL

MySQL is a powerful database management system used for organizing and retrieving data.

To install MySQL, open the terminal and type in these commands:

sudo apt-get install mysql-server libapache2-mod-auth-mysql php5-mysql

During the installation, MySQL will ask you to set a root password. If you miss the chance to set the password while the program is installing, it is very easy to set the password later from within the MySQL shell.

Once you have installed MySQL, we should activate it with this command:

sudo mysql_install_db

Finish up by running the MySQL set up script:

sudo /usr/bin/mysql_secure_installation

The prompt will ask you for your current root password.

Type it in.

Enter current password for root (enter for none): OK, successfully used password, moving on...

Then the prompt will ask you if you want to change the root password. Go ahead and choose N and move on to the next steps.

Once you're done with that you can finish up by installing PHP.


STEP:3 INSTALL PHP

PHP is an open-source web scripting language that is widely used to build dynamic web pages.

To install PHP, open the terminal and type in this command.

sudo apt-get install php5 libapache2-mod-php5 php5-mcrypt

After you answer yes to the prompt twice, PHP will install itself.

It may also be useful to add PHP to the directory index, to serve the relevant PHP index files:

sudo nano /etc/apache2/mods-enabled/dir.conf

PHP also has a variety of useful libraries and modules that you can add on to your virtual server. You can see the libraries that are available.

apt-cache search php5-

Once you decide to install the module, type:

sudo apt-get install name of the module

You can install multiple libraries at once by separating the name of each module with a space.

STEP:4 RESULTS — See PHP on your Server

Although LAMP is installed, we can still take a look and see the components online by creating a quick php info page

To set this up, first create a new file:

sudo nano /var/www/info.php

Add in the following line:

<?php phpinfo(); ?>

Then Save and Exit.

Restart apache so that all of the changes take effect:

sudo service apache2 restart
