How To Install Linux, Apache, MySQL, PHP (LAMP) stack on Ubuntu

LAMP Stack Apache MySQL PHP Ubuntu

For Ubuntu 12.04 – see this updated tutorial for Ubuntu 14.04.

Step 1: Install Apache

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

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

sudo apt-get update
sudo apt-get install apache2

ifconfig eth0 | grep inet | awk ‘{ print $2 }’


Step 2: Install MySQL

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

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

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

sudo mysql_install_db

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.

It’s easiest just to say Yes to all the options. At the end, MySQL will reload and implement the new changes.

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
… Success!

Normally, root should only be allowed to connect from ‘localhost’. This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
… Success!

By default, MySQL comes with a database named ‘test’ that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
– Dropping test database…
… Success!
– Removing privileges on test database…
… Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
… Success!

Cleaning up…

Step 3: Install PHP

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

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

Add index.php to the beginning of index files. The page should now look like this:

 

DirectoryIndex index.php index.html index.cgi index.pl index.php index.xhtml index.htm

 

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

apt-cache search php5-

Terminal will then display the list of possible modules. The beginning looks like this:

php5-cgi – server-side, HTML-embedded scripting language (CGI binary)
php5-cli – command-line interpreter for the php5 scripting language
php5-common – Common files for packages built from the php5 source
php5-curl – CURL module for php5
php5-dbg – Debug symbols for PHP5
php5-dev – Files for PHP5 module development
php5-gd – GD module for php5
php5-gmp – GMP module for php5
php5-ldap – LDAP module for php5
php5-mysql – MySQL module for php5
php5-odbc – ODBC module for php5
php5-pgsql – PostgreSQL module for php5
php5-pspell – pspell module for php5
php5-recode – recode module for php5
php5-snmp – SNMP module for php5
php5-sqlite – SQLite module for php5
php5-tidy – tidy module for php5
php5-xmlrpc – XML-RPC module for php5
php5-xsl – XSL module for php5
php5-adodb – Extension optimising the ADOdb database abstraction library
php5-auth-pam – A PHP5 extension for PAM authentication
[…]

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.

Congratulations! You now have LAMP stack on your droplet!

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:

 

Then Save and Exit.

Restart apache so that all of the changes take effect:

sudo service apache2 restart

Finish up by visiting your php info page (make sure you replace the example ip address with your correct one): http://12.34.56.789/info.php
