In the world of web hosting, stability and security are everything — especially when you’re running shared hosting.

One bad script, a hacked account, or a sudden traffic spike on one website can take down dozens of others sharing the same server.

That’s where CloudLinux OS comes in.
Built specifically for shared hosting environments, CloudLinux helps isolate, stabilize, and secure every user account — without sacrificing server performance.

Let’s break down what makes it so powerful, and why PLiKhost recommends it for serious hosting providers.

🔍 What Is CloudLinux?

CloudLinux OS is a specialized Linux distribution designed for web hosting servers. It replaces the standard OS (like CentOS or AlmaLinux) with a system that offers:

• Account-level resource isolation

• Better stability under high load

• Enhanced security

• Tools made for hosting providers and resellers

It’s fully compatible with cPanel/WHM, making it a popular choice for hosts around the world.

🔐 Why It’s a Game-Changer for Shared Hosting

Here’s what makes CloudLinux essential for shared environments:

1. 🧱 LVE (Lightweight Virtual Environment)

Think of LVE as a mini container for each user.

• Each hosting account gets its own CPU, memory, I/O limits

• No more “noisy neighbors” affecting other sites

• If one site goes viral or gets attacked, others remain unaffected

✅ Result: Better uptime and predictable performance for all users.

2. 🛡️ CageFS: Account Isolation for Maximum Security

CloudLinux uses CageFS to isolate file systems, so one user can’t access or “see” another user’s data.

• Prevents privilege escalation attacks

• Hides sensitive system files

• Contains the damage if one account is compromised

✅ Ideal for hosting multiple clients on a single server.

3. 🚀 MySQL Governor: Control Heavy Database Usage

Shared servers often slow down due to heavy MySQL queries.

CloudLinux’s MySQL Governor monitors and limits abusers — without killing performance.

• Tracks CPU and concurrent DB connections

• Prevents runaway queries

• Keeps database usage fair for everyone

✅ Your WordPress site stays fast, even if someone else is misbehaving.

4. 🔄 PHP Selector: Multiple PHP Versions Per User

Different apps need different PHP versions. CloudLinux lets each account:

• Choose their own PHP version (from 5.6 to 8.x)

• Enable/disable PHP extensions

• Set custom limits (memory, execution time, etc.)

✅ No more conflicts between websites on the same server.
