step 2: ssh to server then execute sudo chmod +x install_nginx.sh
step 3: ./install_nginx.sh
step 4: Composer required press Enter to generate Security.salt

Test pagespeed:
From your computer, open server address on browser then F12, choose Network tab.
If result have x-page-speed:"1.11.33.2-0" is ok.

Next test cakephp: access your_server_address.example
