install dropal in ubuntu server

So, I found a couple of articles, very practical, that explain how to install drupal in a ubuntu linux from scratch. First one is how to install LAMP http://idroot.net/tutorials/install-lamp-stack-ubuntu-16-04/ and the second one is how to install drupal http://idroot.net/linux/install-drupal-ubuntu-16-04/. Just copy and paste command lines in your ubuntu as root, first the LAMP part and second the drupal article.
