What is CloudLinux?

CloudLinux is a Linux operating system designed to enhance data security, stability and density within shared hosting environments. Furthermore, its capabilities allow you to monitor and control server resources such as memory usage, CPU capacity and I/O bandwidth consumption.

Lightweight Virtual Environment (LVE) protects each account on a server individually, so if one account’s website becomes compromised it only affects that account and not any others on that server – thus helping avoid neighbour effects that can cause downtime for everyone on that server.

It is a Linux-based operating system

CloudLinux is a Linux-based operating system designed to make shared hosting environments safer and more reliable. Through modifications to its kernel, its modifications allow more granular control of server resources such as memory and CPU usage, while simultaneously increasing security by restricting access to configuration files of other users on the same server and thus protecting against malware or hackers from accessing vulnerable files and slowing down other websites hosted there.

CloudLinux uses LVE (lightweight virtualized environment) technology to partition customers on shared servers into tenants, giving each tenant their own set of resources. This ensures that if one account uses too much memory or CPU resources, this won’t have an adverse effect on other accounts on the same server. In addition, this system can limit how much physical memory each customer can use to prevent memory leaks; limit disk IO requests; limit database queries per customer to reduce server-side attacks; or set limit restrictions that protect customers against memory leaks by restricting physical memory use per customer or user.

Shared hosting requires this feature as it protects websites from going down due to any one attack, while simultaneously identifying its source and throttling it in real-time if needed. Thus ensuring a stable web hosting environment and increasing customer satisfaction.

Other features of CloudLinux include Hardened PHP, which addresses security flaws in older versions of this programming language. This is important as hackers often exploit outdated PHP to gain entry to servers. Furthermore, Hardened PHP helps protect against symlink attacks and track exploits.

CloudLinux does offer considerable advantages, yet some drawbacks must also be considered. There is a significant learning curve associated with it and may not work seamlessly with certain third-party software and applications. Furthermore, it can slow down websites considerably and isn’t suitable for large databases.

CloudLinux remains an outstanding option for shared hosting platforms despite these constraints, offering its unique features which make it efficient and reliable for cPanel customers alike. Not only does CloudLinux improve stability; it also features tools which optimize website and server performance.

It is compatible with cPanel

CloudLinux is compatible with cPanel, so web hosts can easily integrate it into their existing systems without changing control panels or server management software. Furthermore, CloudLinux features that enhance user stability and security – including restricting how much CPU and memory a single account uses; blocking access by unauthori zed users from configuration files or private information that could otherwise become accessible; as well as restricting CPU usage per account to prevent server overloading due to one account overusing resources – make it the perfect addition for secure user environment!

The system utilizes LVE (Lightweight Virtualized Environment) to segregate each website account. This enables the operating system to assign different sets of resources for each site so as to not overload a server and cause downtime for other accounts; additionally it identifies abusers and takes appropriate action against them.

Shared hosting environments often experience downtime because one or more websites consume all available server resources – usually caused by heavy sites or poorly optimized scripts. CloudLinux OS addresses this problem through kernel modifications which allow for isolation on a per-user basis; similar to OpenVZ or other virtualization technologies.

One benefit of CloudLinux OS is helping improve server density and security. Unlike other Linux distributions, CloudLinux OS was specifically created for multitenancy and provides several performance optimizations that increase efficiency while saving money and increasing provider profits margins.

Operating systems also provide enhanced security features to combat malicious users from attacking other accounts on the same server, such as security patches that are released regularly or lightweight virtualized environments that block hackers from gaining access to vulnerable files. These are especially helpful in today’s environment of malware and other vulnerabilities.

As well, this operating system is compatible with many third-party software interfaces, including cPanel and DirectAdmin. To purchase it, visit the cPanel Store where purchasing is relatively straightforward: to order a license simply log in with your account credentials and click Cart interface – selecting license type will result in this page refreshing and showing pricing information; once complete click Review and Checkout interface before finalising purchase process.

CloudLinux is secure

Cloud servers must be secure to protect sensitive data and prevent attacks from malicious users. A few security measures are essential, including setting up secure user accounts and enabling sudo access control; the latter enables you to take actions normally require root privileges without actually needing root login privileges – something essential in protecting both website visitors and yourself from attackers.

Shared hosting environments often experience one site using up all available resources and slowing or even failing to function, leading to slowdown or failure for other websites on that server. When this occurs, system admins must limit resource use of that particular website so other websites do not become affected; CloudLinux helps solve this issue by isolating each account into its own virtual environment and keeping tabs on usage data.

Cgroups (control groups) provide another layer of security by allocating and allocating CPU, memory and I/O resources across processes in a group. This ensures that no single website can take down an entire server at once while also helping system administrators identify which websites consume most resources so they can take appropriate actions against those sites using too much.

CloudLinux kernel-level technology also offers additional advantages. For instance, it blocks all known symbolic links (symlinks) to increase security and prevent unauthorized code from running on the server, and improves database performance by tracking and limiting resource usage for each account. Furthermore, CloudLinux offers PHP Selector that allows end-users to select their PHP version needed for websites they manage themselves.

CloudLinux stands out as an outstanding web hosting control panel compatibility solution by working seamlessly with popular web hosting control panels like cPanel, DirectAdmin, and Plesk – making integration easy with existing infrastructures without incurring expensive upgrades or migration costs – while simultaneously cutting down hardware platform costs for multiple apps running concurrently – an excellent option for safeguarding shared hosting environments.

It is easy to install

CloudLinux OS is an ideal turnkey system designed specifically for shared hosting servers, offering advanced features like CentOS with full support from its software company behind it. Compatible with cPanel and provided full support by them both.

CloudLinux stands out with its Lightweight Virtual Environment (LVE) design, which allows administrators to limit the resources allocated per customer on an individual basis and prevent performance spikes which could cause downtime and other issues. Furthermore, this LVE environment includes memory, IO, and CPU limits which help protect customers against malicious attacks.

Installing CloudLinux should be straightforward; follow the instructions from your hosting provider for best results. They may require additional steps not outlined here, but this process should be fairly simple: download an ISO image; ask your provider for access to IPMI and console; mount and install OS;

After you have successfully installed an OS, it’s time to configure your servers. WHM/cPanel provides the easiest method of doing so; simply click “Configure a New Server,” choose CloudLinux as your option and click next.

Once your server has been configured, you can log in and begin using its operating system. The default password is “changeme”, although you can easily change it later on. After you login you can view the Dashboard which shows current usage for features enabled with your system; plus how many users and resellers have reached their resource limits such as CPU RAM IO etc.

If you are migrating an existing server to CloudLinux, make sure you delete its old kernel from yum so it can automatically update to the most up-to-date kernel and keep your server stable without experiencing downtime due to bad kernel updates. Doing this will prevent potential server downtime due to outdated versions.
