CMS or write the engine yourself?

Question

CMS

Good day to all.
Some time ago, an interesting project was born in my head. After careful consideration, I roughly sketched out what should be on the site.
1) user account
2) test system
3) points for each user that can be earned by passing tests
4) blog / post system for registered users
5) messaging between users, adding to friends, creating groups
6) system for displaying mini-articles, separately from blogs, randomly from the database of articles
Well, everything seems to be.
I really want to do the project. Please advise if there is a CMS that can satisfy my wishes or if I need to write the site myself. I myself know only HTML and CSS (superficially), but if necessary, I will learn everything that is needed. If my idea can be realized only by writing everything myself, you can please leave books, courses in those languages ​​that I need.
Thank you all in advance.

Answer 1

if you want to do everything yourself, then focus on at least two years of intensive training.

Answer 2

If the project is for public access (website) - CMS, if for experience - by yourself.

Answer 3

Wow. The manners of a person who knows something like html is superficial. To do something like this, it would be more rational to use a framework, not cms. But to write such a site, you need to master a lot. Here is an approximate list: php, mysql, js + a bunch of little things that will definitely be needed and, most importantly, the Yii framework for example.

Answer 4

CMS is indispensable here)) PHP + Framework + DB Although instead of PHP you can use Python or ROR. Also JS
Well, in short, until you learn all this, then most likely there will be other plans))

Answer 5

Perhaps you should look towards Python (Django) rather than PHP.

Answer 6

1. Under what load do you expect?
2. What is wrong with hiring experienced programmers?
