Install Linux, Apache, MySQL, PHP (LAMP) on Ubuntu
LAMP stack is a group of open source software used to get web servers up and running. The acronym stands for Linux, Apache, MySQL, and PHP. Since the virtual private server is already running Ubuntu, the linux part is taken care of. Here is how to install the rest.
For Ubuntu 12.04
Step One—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:
That’s it. To check if Apache is installed, direct your browser to your server’s IP address (eg. http://18.104.22.1689). The page should display the words “It works!" like this.
How to Find your Server’s IP address
You can run the following command to reveal your server’s IP address.
Step Two—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:
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:
Finish up by running the MySQL set up script:
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.
Step Three—Install PHP
PHP is an open source web scripting language that is widely use to build dynamic webpages.
To install PHP, open terminal and type in this command.
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:
Add index.php to the beginning of index files. The page should now look like this:
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.
Terminal will then display the list of possible modules. The beginning looks like this:
Once you decide to install the module, type:
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 Four—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:
Add in the following line:
Then Save and Exit.
Restart apache so that all of the changes take effect:
Finish up by visiting your php info page (make sure you replace the example ip address with your correct one): http://22.214.171.1249/info.php
