install apache2 php and mysql in ubuntu

nstalling Apache

Now we can get started installing. This will take a few minutes, so grab a beer (or your favorite beverage,) and off we go. To install Apache, type or paste this into your terminal:

sudo apt-get install apache2

Testing Apache

Once apache2 is done installing, you can go ahead and test it by using:

sudo /etc/init.d/apache2 start

If you get a message that it's already running, you're good to go. Now, open up your browser and navigate to:

http://localhost/

Installing PHP

Again, to install PHP, type or paste this into your terminal:

sudo apt-get install php5 libapache2-mod-php5

Once it's finished installing, restart apache, using:

sudo /etc/init.d/apache2 restart

Testing PHP

Now, let's make sure that PHP is working properly. To do this, we're going to run phpinfo(). You can, of course, swap out gedit with your editor of choice.

sudo gedit /var/www/phpinfo.php

Type or paste the following into the document, and save it. (remove the space before the '?php')

Now we can test PHP by browsing to:

http://localhost/phpinfo.php

You should see all of the info about your PHP installation listed on the page, like so. For security reasons, you should remove this page when you're sure that PHP works.

Installing MySQL

Now we can conquer MySQL

sudo apt-get install mysql-server

As MySQL is installing, it will ask you to configure your root password. Make sure that you type it correctly, as it will only ask you once.


Testing MySQL
After that is finished, you can test MySQL by running this, where unixmen  is your password

mysql -uroot -punixmen



If it brings you to a MySQL prompt, you're done! You can type exit to get out of MySQL.



Installing phpMyAdmin
Now, if you want to install phpMyAdmin to have a front end for MySQL, you can use the following



sudo apt-get install libapache2-mod-auth-mysql php5-mysql phpmyadmin
It will ask you to choose a webserver to configure automatically, you can use the space bar to select Apache2. And after that's finished, restart one last time.

sudo /etc/init.d/apache2 restart
Finished!
Now you have your own LAMP (Linux Apache MySQL PHP) server, with phpMyAdmin
