Install Apache, MySQL, PHP on Ubuntu

Installing Apache, MySQL, and PHP on Ubuntu is quite easy. Here is how to install the rest.

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

 sudo apt-get update  
 sudo apt-get install apache2  

That’s it. To check if Apache is installed, direct your browser to your server’s IP address (eg. http://12.34.56.789). The page should display the words “It works!" like this picture below :

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  

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  

Then just follow the instructions to set root password and etc.

To install PHP, open 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  

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

 <IfModule mod_dir.c>  
      DirectoryIndex index.php index.html index.cgi index.pl index.php index.xhtml index.htm  
 </IfModule>  

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  

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.
