How to configure memcache correctly?

Question

Yii

Hello! I have a question for the experts. Here I installed all memcached components on the server, enabled memcache.
By default port 11211 and localhost. Do I need to change localhost and port to the IP address of the server and the port on which the site is running? only one server is used.

Answer 1

What does "the port on which the site is running" mean? 80?
Do you understand what a port is?
It all depends on which applications work with memcached and where these applications are running.
In your case, most likely, you can leave the default settings.

Answer 2

No, you definitely don't need to do this. Otherwise, you will get a memcache open to the whole world, since you ask such questions.
Well, yes - memcache itself does nothing, the application must be able to use it itself (and, of course, really use it).
