Everything you need to know about CloudLinux OS, server security, and license management.
CloudLinux OS is a commercial Linux distribution specifically designed for shared hosting providers. It isolates each hosting account in its own lightweight virtualized environment (CageFS), preventing any single user from over-consuming CPU, RAM, or I/O resources via LVE technology. It also features HardenedPHP to secure old PHP versions. Together, these features radically improve server stability and security.
CageFS is a per-user virtualized file system that uniquely encapsulates each hosting account, preventing them from seeing each other and the server's core system files. When enabled, users cannot view other users' files, processes, or sensitive server configurations. Even if an account is compromised, the attacker remains trapped within that user's CageFS environment. It works transparently for end-users without affecting the hosting experience.
LVE (Lightweight Virtualized Environment) Manager allows server administrators to set precise limits on CPU, Memory, I/O, and concurrent processes per account. If a user exceeds their allocated resources, only their processes are throttled, while other users on the server remain completely unaffected. This eliminates the "noisy neighbor" problem common in shared hosting and ensures fair resource distribution.
HardenedPHP is a CloudLinux technology that backports security patches to old PHP versions that have reached official End-of-Life (such as 5.x and 7.x). Since many legacy sites still require these versions, HardenedPHP provides a secure environment against known vulnerabilities without forcing clients to upgrade their code—a vital feature for hosting providers.
Yes, CloudLinux OS is compatible with both virtual servers (VPS/VDS) and dedicated servers. The license covers a single server installation regardless of the hardware type. It also supports all major control panels like cPanel, DirectAdmin, and Plesk. The installation is straightforward, allowing you to convert an existing CentOS or AlmaLinux server to CloudLinux with one simple command.
CloudLinux licenses are issued per server based on the server's primary IP address. After purchasing from GlobeTier, your IP is registered immediately, and you can begin the installation or conversion. The license is checked automatically at system boot and periodically during runtime. If you change your server IP, you can simply update the license data through your GlobeTier client area.
CloudLinux OS is the world’s most widely used commercial distribution for multi-tenant hosting servers. Trusted by more than 4,000 hosting providers and running on over 200,000 servers worldwide, CloudLinux transforms a standard Linux server into a secure and stable hosting platform that ensures fair resource distribution. By isolating users, securing the PHP environment, and preventing resource abuse, the system ensures that no single account can impact the performance of the entire server.
CageFS technology creates a completely virtualized file system for each user on the server. Each hosting account sees only its own files and a safe set of system tools, and cannot access the home directories of other users, browse the process list, or read sensitive configuration files such as /etc/passwd. This completely eliminates symlink attacks, local privilege escalation, and information disclosure vulnerabilities common in traditional hosting environments.
Lightweight Virtualized Environment (LVE) technology is the backbone of resource management in CloudLinux. It allows administrators to set precise limits for each individual account, including: CPU, physical memory, I/O speed, and concurrent processes. When a user exceeds their quota, only their processes are throttled, while the rest of the server continues to operate at full capacity. The LVE system integrates with all major control panels and provides real-time performance monitoring dashboards.
Many websites rely on old PHP versions that have reached their official end-of-life and no longer receive official security updates. HardenedPHP technology solves this critical issue by backporting security patches to older PHP versions (starting from 5.1), covering hundreds of known vulnerabilities. For hosting providers, this means customers can continue to run their existing applications safely without being forced into software upgrades that might break their sites.
SecureLinks technology is a kernel-level protection that prevents symbolic link (Symlink) attacks, which are among the most dangerous and widely exploited vulnerabilities on servers. While traditional protection relies on Apache or PHP settings that can often be bypassed, SecureLinks operates at the operating system kernel level, making it nearly impossible for attackers to use symlinks to read files from other users or the system.
