How To Install LAMP on Ubuntu 14.04 [Quickstart]

How To Install LAMP on Ubuntu 14.04 [Quickstart]


The LAMP stack (Linux, Apache, MySQL, PHP) is a group of open source software that is typically installed together to enable a server to host dynamic PHP websites and web apps. This guide includes the steps to set up a LAMP stack on Ubuntu 14.04, on a single server, so you can quickly get your PHP application up and running.

A more detailed version of this tutorial, with better explanations of each step, can be found here.

Step 1: Update apt-get package lists

  1. sudo apt-get update

Step 2: Install Apache, MySQL, and PHP packages

  1. sudo apt-get -y install apache2 mysql-server php5-mysql php5 libapache2-mod-php5 php5-mcrypt

When prompted, set and confirm a new password for the MySQL “root” user:

Set MySQL root password

Step 3: Create MySQL database directory structure

  1. sudo mysql_install_db

Step 4: Run basic MySQL security script

  1. sudo mysql_secure_installation

At the prompt, enter the password you set for the MySQL root account:

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

At the next prompt, if you are happy with your current MySQL root password, type “n” for “no”:

MySQL root password prompt:
Change the root password? [Y/n] n

For the remaining prompts, simply hit the “ENTER” key to accept the default values.

Step 5: Configure Apache to prioritize PHP files (optional)

Open Apache’s dir.conf file in a text editor:

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

Edit the DirectoryIndex directive by moving index.php to the first item in the list, so it looks like this:

dir.conf — updated DirectoryIndex
DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm

Save and exit.

Restart Apache to put the change into place:

  1. sudo service apache2 restart

Step 6: Test PHP processing (optional)

Create a basic test PHP script in /var/www/html:

  1. echo '<?php phpinfo(); ?>' | sudo tee /var/www/html/info.php

Open the PHP script in a web browser. Replace your_server_IP_address with your server’s public IP address:

Visit in a web browser:

If you see a PHP info page, PHP processing is working:

Example PHP info page

Delete the test PHP script:

  1. sudo rm /var/www/html/info.php

The sudo apt-get install now says that it can’t install ANY of the php5 packages. You may want to update these instructions.

I have followed this tutorial but when I test my info.php: all I get is a blank page

If you are with permission issues with the wp-content that can help you: in /etc/apache2/envvars


export APACHE_RUN_USER = www-data
export APACHE_RUN_GROUP = www-data


export APACHE_RUN_USER = [you-user]
export APACHE_RUN_GROUP = [you-user]

Remember the final critical step…

Restart Apache to put the change into place: sudo service apache2 restart

For some reason I managed to overlook this step, and while everything appeared to be functioning, I kept getting unexplainable errors that appeared (to the professionals whom I consulted) to be a misconfiguration of the PDO drivers, which I was told meant that PHP could not connect to MySQL.

After about a week of trouble-shooting and head-banging on my desk, this simple (overlooked) restart command solved all my problems. Ouch.
