Installing Apache2 Server, MySQL DB, and PHP on Ubuntu 16.04

Updated 04/10/2021

First thing we need to do is run updates, so login as root.

sudo apt-get update

Second step is to install apache2

sudo apt-get install apache2

Test apache2 server

To see if apache2 was successfully installed

Open web browser and type in 127.0.0.1

Note to view IP address and local loop back address run ifconfig

You should see Apache2 Ubuntu Default Page

“It Works!”

This maybe the best time to go over with you stopping, reload, and starting apache2 server.

NOTE

To start, reload or stop apache2 server.

There are couple different methods to doing this. I like and want my students to use;

sudo service apache2 stop

sudo service apache2 start

sudo service apache2 reload

Note this is different for other OS so you should look up those methods that work for you Linux OS.

Third Step is to install MySQL Server

sudo apt-get install mysql-server

It will ask you for your root password. THEN ask you to set a root password into MYSQL! SAY N to keep the current root password or Y to change the password.

I recommend that my students take No.

Now after install mysql is completed it time to test to see if it’s work.

mysqladmin -u root -p status 

Enter root password.

You will see uptime, Threads, Questions and so on. 

Success! 

I did notice that the step to installing MySQL have streamline since ubuntu 14.0 much faster install in 16.0 

Forth Step install PHP

sudo apt-get install php libapache2-mod-php

By default, the web site directory path is /var/www/html

With that in mind, create and save info.php to html  

To do this open and create new document

<?php

phpinfo();

?>

Note to create this you can use Web Editor such as Bluefish or use vi editor

vi   /var/www/html/info.php

Remember to save it to the html directory as info.php (not info.php.php)

Now to test it and see if PHP is working

Go to http://yourserveripaddress/info.php

This is what you should see:

What if it fails to work!

You may be getting a message that you don’t have permission to the directory var/www

You can see the permission of /var/www has, by this command

ls -l /var/www 

You will see like this (this only for example): (That’s Lower Case L not 1.)

Again, If there is a permission issue when trying to view the info.php complete the following:

Run

ls -l /var/www

to view who currently has rights to that directory.

To add yourself as having rights to that directory do the following:

sudo adduser yourusername www-data

After you completed this task you need to give yourself  “R“  rights permission and ownership to  your name.

sudo chmod -R 775 /var/www

Look again to see your user name is added to the group

             sudo ls -l /var/www 

If you see your user name… success!
