How create several installations of WordPress independents?
I use Digital Ocean about one year. I want create a a service to sell small websites using WordPress as CMS, alright a simple service/panel using Digital Ocean API to create a new domain in apache, database and some configurations.
But I have a HUUUGGGGEEEE question, how create isolated configuration for each domain? Example: Imagine one of this small website infected or hacked. This will create a huge problem for all users.
Exists any tool, to deny one user/website to access other directories/files from other user/website?
== My scenario
1 Droplet to MySQL
1 Droplet to Apache/PHP
1 Droplet to Webmail Domains
*Apache (virtual sever) and MySQL databases are created by API
