title: secure websites running on the same webserver
body: <p>I have two websites running on my own root server (ubuntu/nginx/php-fpm). Now I want to add one more website, a wordpress blog. As you know wordpress can be a security risk and that's why I'm asking myself how to "seperate" wordpress from the other websites. So when wordpress got hacked, I want the attacker to be trapped within wordpress. It would be fatal if he could "see more" than the wordpress blog. What is your strategy to protect websites from each other?</p>
