Ways to automate website development?

Question

Web development

Hello,
There are several sites on a LEMP server (CentOS, Nginx, MariaDB, PHP-FPM), you need to do something like a Dev / Test server in order to first test all the changes there and then apply them automatically if necessary on the production / main server. Please advise in which direction to look, and whether all this makes sense at all.

Answer 1

Why didn't git work? If you want to introduce new functionality and test it, create a new branch, if everything suits you, merge it into the prod. if not, keep working.
