A CloudLinux shared license is a lower-cost licence for CloudLinux OS, the Linux operating system built for shared hosting servers. It lets you run CloudLinux on your own VPS or dedicated server through a shared licensing arrangement rather than buying directly from CloudLinux. You get the same core job done: every hosting account on the server is isolated and given its own resource limits.<\/p>\n
Tremhost’s shared licences receive official vendor updates.<\/p>\n
This guide explains what CloudLinux does, how it differs from cPanel, who benefits from it, and what to check before you buy a shared licence.<\/p>\n
On a normal shared server, every website draws from the same pool of CPU, memory and disk input\/output. One busy or badly coded site can slow down or crash the others. CloudLinux changes this at the operating system level.<\/p>\n
CloudLinux places each hosting account in its own Lightweight Virtual Environment. The server administrator sets limits for each account, such as CPU, physical memory, disk I\/O, the number of processes and the number of simultaneous connections (entry processes). When an account hits its limit, only that account slows down. The rest of the server keeps running normally.<\/p>\n
CageFS gives each user a separate, virtualised view of the file system. A user cannot see other customers on the server or read sensitive system files. If one website is compromised, CageFS makes it much harder for the attacker to move sideways into other accounts.<\/p>\n
The PHP Selector lets each account choose its own PHP version and extensions, so an old application and a new one can run on the same server. Python and Ruby selectors do the same for those languages. This saves you from forcing every customer onto one version.<\/p>\n
MySQL Governor tracks database usage per account and can restrict users whose queries overload the database server. Heavy database use is one of the most common causes of slow shared servers.<\/p>\n
People often compare a CloudLinux shared license with a cPanel shared license as if they were alternatives. They are not. They do different jobs and most hosting servers use both.<\/p>\n
CloudLinux integrates with cPanel, Plesk and DirectAdmin. With cPanel, administrators manage LVE limits from inside WHM, and customers can see their own resource usage in cPanel. So the practical question is rarely “CloudLinux or cPanel?” It is “Do I need CloudLinux on top of my control panel?”<\/p>\n
If you host many customer accounts on one server, CloudLinux is close to essential. Resource limits stop one customer from hurting everyone else. That means fewer outages, fewer support tickets and more accounts per server before you need new hardware. CageFS also limits the damage when a customer’s site is hacked.<\/p>\n
If you run 20 or 50 client websites on a VPS, you face the same problem as a hosting company. One client’s plugin bug should not take every other client offline. CloudLinux keeps each site in its own box.<\/p>\n
You do not buy CloudLinux yourself if you are on a shared plan. But it is worth asking your host whether they use it. On a CloudLinux server, your site has guaranteed resources and is isolated from your neighbours. That is a better position than sharing an unrestricted pool.<\/p>\n
If your server runs a single website or application that you control, CloudLinux adds less value. Isolation matters most when several separate users share one machine.<\/p>\n
A shared licence is a licensing arrangement offered by a third party, not a licence issued directly to you by CloudLinux. The provider holds the vendor licences and supplies activation for your server, usually tied to its IP address. The software itself is the same CloudLinux OS, and the price is usually much lower than buying direct.<\/p>\n
That trade-off is reasonable for many businesses, but read the terms before you buy. Check these points:<\/p>\n
Take a full backup before converting a live server. If you would rather not manage this yourself, a managed server with CloudLinux already installed is an option.<\/p>\n
Tremhost offers a CloudLinux shared licence with unlimited accounts for your own server. Current monthly, yearly and one-off prices are listed on the CloudLinux licence page<\/a>, and other licences, including cPanel, Imunify360, LiteSpeed and JetBackup, are on the licences page<\/a>. Like all shared licences, this is a shared licensing arrangement, so read the terms on the page before ordering.<\/p>\n If you want CloudLinux without installing it, Tremhost’s managed cPanel VPS<\/a> comes with cPanel and WHM, LiteSpeed, CloudLinux, Imunify360 and backups set up by Tremhost technicians. Tremhost reseller hosting plans also run on CloudLinux. If you are new to reselling, read what is reseller hosting<\/a> first.<\/p>\n It activates CloudLinux OS on your server, so the operating system you run is the same. The difference is the licensing route. A shared licence comes through a third party, and support and terms come from that provider, not from CloudLinux.<\/p>\n No. CloudLinux works with cPanel, Plesk and DirectAdmin, and can run without a panel. Most hosting servers use it with a control panel because that makes limits easy to manage.<\/p>\n Not directly. It does not speed up a single site. It stops other accounts from slowing your site down, which keeps performance steady on a busy server.<\/p>\n Yes, as long as you have root access and a supported operating system. KVM virtual servers are suitable because they run their own kernel.<\/p>\nFrequently asked questions<\/h2>\n
