How to Install SolusVM Slave on AlmaLinux or CentOS

SolusVM Slave is installed on a dedicated server or node to host and manage virtual machines. It works alongside the SolusVM Master panel, allowing you to provision and manage VPS instances using virtualization technologies such as KVM or Xen.

In this guide, you’ll learn how to install SolusVM Slave on AlmaLinux or CentOS and connect it to your SolusVM Master server.

SolusVM Slave Installation Requirements

Before you begin, make sure you have:

• A fresh installation of AlmaLinux 8, CentOS Stream 8, or CentOS 7.
• Root access to your VPS or dedicated server.
• An active internet connection.
• A SolusVM Slave license for each node.
• An SSH client such as PuTTY or Terminal.

Important: Installing SolusVM on a clean operating system helps prevent software conflicts and ensures a smooth setup.

Step 1: Connect to Your Server via SSH

Log in to your server as the root user.

For AlmaLinux 8 or CentOS Stream 8

Run the following command:

curl -o installer https://files.soluslabs.com/solusvmphp7/install/installer && chmod +x installer && ./installer

For CentOS 7

Run:

curl -o install.sh https://files.solusvm.com/install.sh && sh install.sh

This will start the SolusVM installation process.

Step 2: Select Your Virtualization Type

During installation, you’ll need to choose the virtualization technology for your node.

On CentOS 7

You’ll be presented with several options. Most users choose:

• 2 — KVM
• 3 — Xen

For example, to install a KVM node, enter:

2

and press Enter.

On AlmaLinux 8 or CentOS Stream 8

Select the KVM Virtualization Node option when prompted.

Note: KVM is the most commonly used virtualization technology because it offers excellent performance and broad operating system compatibility.

The installation process usually takes between 15 and 20 minutes.

Step 3: Save the Slave Keys

After the installation is complete, SolusVM will display:

• The node keys (Slave keys).
• Additional instructions based on the selected virtualization type.

Save these keys in a secure location.

You’ll need them when adding the node to your SolusVM Master server.

Congratulations! You’ve successfully installed SolusVM Slave.

Adding the Node to SolusVM Master

Once the slave node is installed, log in to your SolusVM Master panel and use the generated Slave keys to add the node.

After the node is added successfully, you’ll be able to:

• Create VPS instances.
• Allocate resources.
• Manage virtual machines.
• Monitor node performance.

Note: Each slave node requires its own SolusVM Slave license.

Common Installation Issues

Installation Failed

Installation problems are often caused by:

• Unsupported operating systems.
• Existing software conflicts.
• Insufficient RAM or disk space.
• Network connectivity issues.

Virtualization Option Not Available

If KVM or Xen options are missing:

• Verify that your server supports hardware virtualization.
• Enable Intel VT-x or AMD-V in the BIOS.
• Confirm that virtualization extensions are available.

Unable to Add the Node to SolusVM Master

If the node won’t connect:

• Verify that the Slave keys were entered correctly.
• Ensure required firewall ports are open.
• Check network connectivity between the Master and Slave servers.
• Confirm that the Slave license is active.

Why Use SolusVM Slave Nodes?

Slave nodes allow you to:

• Host VPS instances on multiple servers.
• Scale your infrastructure easily.
• Separate workloads across different nodes.
• Improve resource management.
• Centralize administration through SolusVM Master.

Conclusion

Installing SolusVM Slave on AlmaLinux or CentOS enables your server to host virtual machines and integrate with the SolusVM Master panel. Once connected, you can provision VPS instances, manage resources, and scale your hosting infrastructure efficiently.

Tip: Before deploying production VPSs, secure your node, configure backups, and verify that hardware virtualization is enabled for optimal performance.
