apache2 - After lamp install, can't run php scripts on localhost - Ask Ubuntu

i followed tutorial install lamp: https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu

at step 4: see php on server, told following:

first create new file:

> sudo nano /var/www/info.php 

add in following line:

<?php phpinfo(); ?> 

then,i should see page lots of information, when type in localhost/info.php

but page white. no error message.

if type in localhost/index, apache2 ubuntu default page loads.

later, moved info.php /var/www/html page still white.

at point, i'm clueless. suggestions fix problem?

first of all, rather create public_html folder in user's home directory

mkdir public_html 

by default, php scripts in user directories disabled. in other words need enable them. instructions, seem have php5 installed. enable php scripts in user directories, edit /etc/apache2/mods-available/php5.conf file root.

in case did

sudo vim /etc/apache2/mods-available/php5.conf 

when file open, comment out following lines (instructions inside file too)

<ifmodule mod_userdir.c>     <directory /home/*/public_html>         php_admin_value engine off     </directory> </ifmodule> 

and save it. make sure userdir enabled with

sudo a2enmod userdir 

move info.php file public_html folder. restart apache2 with

sudo service apache2 restart 

go http://localhost/~yourusername/info.php , should work perfectly.
