CloudLinux OS is an operating system from the RHEL-compatible family, built specifically for web hosting servers. On a typical shared hosting server, one busy site or one runaway script can eat all the CPU and memory, and every other customer feels the slowdown immediately. CloudLinux solves exactly that problem: each account gets its own resource limits and its own isolated environment.

For hosting companies, web agencies and admins running dozens or hundreds of sites on one server, the difference shows up in stability and in the number of support tickets. An account that hits its limits is slowed down on its own, not the whole server. Users cannot see each other, cannot read each other's files and can run the PHP version they need.

At cloudlinux.ro you buy your CloudLinux license monthly, with no yearly commitment. The license is bound to the public IPv4 address of the server and works both on a server hosted with us and on one at any other provider or in your office. All you need is a free cloudlinux.ro account.

LVE: per-account resource limits

Lightweight Virtual Environment puts every user in a lightweight container with limits on CPU, memory, processes and I/O. One overloaded site can no longer drag the whole server down.

CageFS: user isolation

Each account sees only its own virtualised file system. Users cannot list other accounts, cannot read sensitive configuration files and only get access to the binaries you allow.

PHP Selector and multiple versions

Every account can pick its PHP version and extensions from the alt-php packages maintained by CloudLinux, including older versions that still receive security patches.

MySQL Governor

Tracks database usage per user and can throttle accounts that abuse MySQL, so one customer's heavy queries do not lock up the database for everyone else.

Works with popular panels

Integrates with cPanel, Plesk and DirectAdmin, so limits, usage statistics and selectors show up right inside the panel, for both the admin and the end users.

Convert from AlmaLinux or Rocky

No reinstall needed. A RHEL-compatible system such as AlmaLinux or Rocky Linux can be converted to CloudLinux OS with the official conversion tool.

How ordering works

1
Order from the console
Open the Licences section of the cloudlinux.ro console, pick the CloudLinux OS edition and confirm. You only need a free account and credit on it.
2
For any server
Choose "a server I have here" or "my own server, anywhere". For an external server you enter its public IPv4 address and a name, and the license is bound to that IP.
3
Monthly billing from credit
You pay one month in advance from prepaid credit and the license renews automatically every month while credit allows. Cancel any time: the month already paid runs to its end and is not refunded.
4
Your key appears instantly
The license is issued instantly. The activation key shows up in the console together with installation steps for your server.

Installation and activation

1
Prepare the server
Start from a supported system such as AlmaLinux or Rocky Linux, fully updated and with root access. Take a backup or snapshot before converting.
2
Run the conversion
Download the official cldeploy conversion tool and run it with your license details. Follow the exact activation steps shown in the console next to your key, since they differ slightly by edition and activation type.
3
Reboot into the CloudLinux kernel
After conversion, reboot the server to load the CloudLinux kernel. Then check that the license shows as active and that LVE is running.
4
Set your limits
From your control panel (cPanel, Plesk or DirectAdmin) or the command line, set default limits, enable CageFS and choose which PHP versions users can select.

LVE: resource limits for every account

On a regular Linux server every site competes for the same resources. When a WordPress plugin gets stuck in a loop or a site is hit by a wave of bot traffic, the CPU goes to 100%, memory fills up and every other site responds slowly or not at all. For a hosting provider that means tickets, unhappy customers and hours spent hunting for the culprit.

LVE (Lightweight Virtual Environment) places each account in a kernel-controlled container with clear limits: how much CPU it can use, how much memory, how many concurrent processes and how much disk I/O. When an account hits its limit only that account slows down, and the rest of the server carries on as normal. The admin can see in the statistics who hit their limits and when, which makes troubleshooting far quicker. Limits can be set globally or per package, and customers who need more can be moved to a bigger plan instead of being allowed to affect everyone.

CageFS and PHP Selector: security and flexibility

CageFS gives every user a virtualised file system in which they see only their own files and a restricted set of binaries and libraries. An attacker who compromises one site cannot list the other accounts, cannot read other users' configuration and has far fewer tools available to escalate the attack. On a server with hundreds of sites this isolation matters a great deal.

PHP Selector solves a practical problem: customers run different applications, some modern and some old, which need different PHP versions. With the alt-php packages each account picks its version and extensions right from the panel, without the admin maintaining several installs by hand. Older versions keep receiving security patches from CloudLinux, which lowers the risk when a customer cannot upgrade their application straight away.

CloudLinux OS vs AlmaLinux and Rocky Linux for shared hosting

AlmaLinux and Rocky Linux are free, stable distributions and excellent for single-application servers or a VPS run by one team. CloudLinux OS starts from the same RHEL-compatible base, so the packages, commands and admin experience feel familiar. The difference appears when the server holds many users who do not trust each other.

On AlmaLinux or Rocky you can get part of the way with manual configuration, but LVE, CageFS, MySQL Governor and PHP Selector come built into CloudLinux and into the popular control panels, tested together and maintained by the vendor. For a personal server a free distribution is usually enough. For commercial shared hosting, a CloudLinux license typically pays for itself through fewer incidents and less admin time. And since a server can be converted without a reinstall, you can start on AlmaLinux and move to CloudLinux as your customer base grows.

Frequently asked questions

Do I need a server with cloudlinux.ro to buy the license?

No. The license works on any server with a public IPv4 address, whether it is hosted with us, at another provider or in your office. You only need a free cloudlinux.ro account and enough credit to pay for the first month.

How is the CloudLinux license billed?

The license is paid monthly, in advance, from the prepaid credit on your account. It renews automatically every month as long as you have enough credit. Prices shown on this page exclude VAT.

Can I cancel at any time?

Yes, you can cancel from the console whenever you like. The month already paid runs to its end and the license simply does not renew afterwards. The current month is not refunded, so it makes sense to cancel towards the end of the period if you want to use the full month.

What happens if my server IP changes?

The license is bound to a single public IPv4 address. If the server gets a new address, the existing license will no longer be valid for it. Open a support ticket before the change and we will help you find the simplest option for your situation.

Which edition should I pick for a VPS with one site?

For a single website or a single hosting account, CloudLinux OS Solo is the edition designed for that case. If the server will host several customers, each with their own account, choose Shared or Shared Pro, which include LVE and CageFS for account isolation.

Does CloudLinux work with cPanel, Plesk or DirectAdmin?

Yes, CloudLinux OS integrates with all three, and features such as LVE limits, PHP Selector and usage statistics appear inside the panel interface. It can also run without a panel and be managed from the command line. The control panel license is purchased separately.

Do I have to reinstall my server for CloudLinux?

Usually not. A server running AlmaLinux, Rocky Linux or another supported compatible system can be converted with the official cldeploy tool, followed by a reboot. We still recommend a backup or snapshot first and checking that your OS version is supported.

What support do I get?

We provide support through tickets, in Romanian and English, for license issuing, activation and account or billing questions. For advanced system configuration we can point you to the vendor documentation and the right steps for your server.
