The problem of Building php+mysql+apache Environment in ubuntu

novice,
1. My question
after ubuntu installs apache2,php7.0,mysql and phpmyadmin and then accesses from the outside, the static part of the page can be displayed, but the dynamic part cannot be displayed (using phpstudy to display the dynamic part when simulating the server locally), I judge that it may be the problem with the http service.
2. My steps
I follow the steps in the blog Click here to see the blog steps and install apache2,php7.0,mysql and phpmyadmin in turn.
then I put my project under www/html and accessed it from outside to show the static part of the page, but the dynamic part could not be displayed (using phpstudy to display the dynamic part when simulating the server locally), I decided that it might be the problem with the http service.
3. How to solve the desired answer
? Or what other information do you need me to provide to judge?
