AlmaLinux Elevate In-Place CentOS 7 to EL8 Migrations and Resource Requirements?

1.5 GB is the absolutely bare minimum, local installation only or local lan NFS. And since almost all EL forks are updating not locally but via public HTTP(s) mirrors.

You are going to run out of memory on 1.5 GB guaranteed. Even as early as updating.

8 GB of memory use you get with a nice forum right from clean boot. Those quickly go to 16,32,64,128,256 GB etc.

Should you have sites with 10 or 20 visitors a day I would not even recommend CMM. The emphasis and time will be on creating content and making the site bigger, better known and more popular.

Shared hosting is then sufficient until you grow enough. After all, no time, you can spend your time better. But that is my opinion. Which is neither right nor wrong.

I do not host small sites on CMM. It's not cost-effective. Does not take away from the fact that CMM is top software. But for the big projects. The top forums in the world running on it, where every ms counts. For a website with a few visitors it is a nice to have for example the PHP Intel optimalization patch, Cloudflare tls records or hpack patch but nothing more. It will not attract more visitors.

So why spend hours and hours tweaking when a small site can only grow with unique content?

 

You can also host low volume websites like this on cloudpanel.io. Get the cheapest Hetzner ARM server, as it also runs on ARM and you're good to go. I also definitely don't want to advertise the competitor. And cloudpanel.io is a totally different product, with a different target audience. Again not that I am writing that CMM would not be great. I just don't think CMM is suitable/the best option for low volume sites.

And for example, a Cloudflare subscription is that even necessary with 850 visitors? Or are you running certain explicit content that is prone to attacks like DDOS etc?

Hetzner does als provide basis protection, like DDoS.

In the event of a major attack on Cloudflare, you will still be deactivated or transferred to a paid package. I don't really understand the popularity of free Cloudflare.

Additionally when you have a website without explicit content and not large/popular, I don't see what everyone need to do with Cloudflare.

Explicit content though? Tjah I know examples where... yes even after minute 1 online you are attacked right away.

 

I don't think I understand you. Where do I mention Cyberpanel at all?

 

The point is when does the site become worth it, and that's a tricky one. Nowadays, with a new project, as fresh fish, with no network or connections. It is very difficult to get unique content noticed within the algorithm. In order to get visitors. In fact I think even on certain hugely popular topics the boat has already sailed. Unless you have something really Unique's. A few still manage to do that.

CMM seems easy, Cloudflare ditto. But that is difficult for us to judge. Should it be your job managing multiple high volume costumers and/or you have secretly put in 1000's of hours all these years. Then you are secretly already master of the product and very very good.

The question is whether an entrant, given the difficult market and limited time (a new project cannot possibly be equal livelihood unless previous successes or wealthy parents). So you're stuck with your day to day work.

Should you spend this limited time after working hours on "mastering" Cloudflare and CMM or creating unique content, and mastering content creating.

Then the main question should then be: I become a content creator or will I manage several large sites?

And then we come to the part discussed earlier. Should you have or manage high volume site(s) then the choice is pretty simple CMM + Cloudflare. But for one or a few low volume site(s). I would put my priority on mastering content creation.

Should it 'still' go very well after some time. Then there are usually more than enough resources to hire an outside pro. So that you become even better and bigger in the content area.

 

In my view, Cloudpanel is kind of self-hosted shared hosting light, with your/their own accounts on your own server for low volume sites. CMM runs as single user: root without GUI and is usually for heavy websites and/or or lots of visitors, data etc. So not the same thing.

Cloudpanel does have lower recs:

as CMM is 4 GB.
And yes Cloudpanel is much easier than CMM. Cyberpanel I do not know. Therefore, I don't understand why you are bringing it up again.

That's right. Since the minimum of CMM requires 4 GB. I don't even start below 8GB. You shouldn't want a system with minimum specs. But that's my opinion. Advice is/was to not use that 5$ server anyway. Since for what I read Hetzner 5$ servers are on 2GB and even the minimum EL is on 3GB and CMM 4GB as written above.

But I wouldn't worry. It's just advice and what I would do. You are of course free to do what you want. After all, you can follow an advice or disregard it.

 

My advice ends here. Every answer whatever is given to your own questions you question again and again. Good luck and have a nice day.

Red Hat's official product sets a minimum of 3GB of memory. CentOS, AmaLinux and Rocky Linux on where CMM is based on, without (L)EMP is a clone and applies the same. The links to the sources are frequent in this topic.

As CMM is still a beta on EL8 it has not been shown on the website: https://centminmod.com/ As indicated, this will not happen until about January 31, 2024.

 

I think that the installer to creates 4GB swap even in EL7 boxes without any swap when you start installing CMM.
Its way too much for basic LEMP usage without any anti-malware/virus scanning softwares or php composer, I even have one small box running CMM and purpose is mainly nginx reverse proxy so it would prolly run smoothly without any swap but I like to use it with CMM because of optimized nginx.
Nowdays I usually start creating swapfile manually before I start installing CMM. It would be nice if users could someday define swapfile size in custom_config
