Two wordpress sites on the same database?

Question

MySQL

Friends, tell me, there is a site on wordpress with one database, wordpress clearly prescribes the url. You need to make an exact copy of the site on another domain, everything would be nothing just to copy and change the url to the desired domain, but there is a need for two sites to be managed from one admin panel, that is, if I make changes on site1.ru, automatic changes occur on the second site2 .ru
Tell me where to dig?
