Hands-On exercises

Here's a guide on how to use the Proxmox web console:

1.Open your web browser and navigate to the IP address or hostname of your Proxmox server. The default port for the Proxmox web console is 8006, so the address will look something like this: ​https://your-proxmox-server:8006/

2.Enter your Proxmox username and password to log in.

Once you are logged in, you will see the Proxmox dashboard, which displays system status and resource usage. You can see an overview of your virtual machines and containers, monitor system performance, and access various configuration options.

To manage virtual machines or containers

• click on the "Virtual Machines" or "Containers" tab in the left-hand pane. From there, you can view and manage individual virtual machines or containers, create new ones, and configure settings such as CPU, memory, storage, and networking.

To configure networking

• click on the "Network" tab in the left-hand pane. From there, you can manage network interfaces, bridges, VLANs, and firewall rules.

To create a new virtual machine or container

• click on the "Create VM" or "Create CT" button in the upper right-hand corner of the screen. This will launch a wizard that guides you through the process of creating a new virtual machine or container.

To monitor system performance

• click on the "Dashboard" tab in the left-hand pane. This will display real-time performance metrics for CPU, memory, disk usage, network traffic, and more.

Proxmox Network and Clustering

Proxmox networking is the process of configuring networking settings within the Proxmox environment, while Proxmox clustering is the process of creating a group of physical or virtual servers that work together to provide a unified virtualization environment.

Proxmox networking and clustering are important aspects of the Proxmox virtualization platform as they allow users to customize and scale their virtualization environment based on their needs.

Proxmox Networking

Proxmox networking can be done through the Proxmox web interface or command line interface (CLI). The Proxmox networking setup involves configuring the network interfaces, setting up bridges, creating VLANs, and setting up firewall rules. The networking settings can be customized to meet the needs of the virtual machines or containers that will be hosted on the Proxmox environment.

• Log in to the Proxmox web interface or CLI as a user with administrative privileges.

• Click on the "Datacenter" node in the left-hand pane, then click on the "Network" tab.

• Click on the "Create" button to add a new network interface.

• Select the type of network interface you want to create (e.g., Linux Bridge or Open vSwitch), then provide a name for the interface.

• Configure the network settings for the interface, including IP address, subnet mask, and gateway. You can also configure VLANs and firewall rules at this point.

• Click "OK" to save the network interface.

• Repeat the above steps to create additional network interfaces as needed.

Proxmox Clustering

Proxmox clustering is the process of creating a group of physical or virtual servers that work together to provide a unified virtualization environment. The Proxmox cluster provides features such as load balancing, high availability, and shared storage. Proxmox clustering can be done through the Proxmox web interface or CLI. The cluster setup involves configuring network settings, creating a shared storage, setting up a cluster manager, and adding nodes to the cluster.

• Log in to the Proxmox web interface or CLI as a user with administrative privileges.

• Click on the "Datacenter" node in the left-hand pane, then click on the "Cluster" tab.

• Click on the "Create" button to add a new cluster.

• Provide a name for the cluster and specify the IP address of the cluster manager.

• Create a shared storage volume that all nodes in the cluster can access. This can be done using a SAN, NAS, or other storage device.

• Add additional nodes to the cluster by specifying their IP addresses and joining them to the cluster.

• Configure high availability (HA) settings for virtual machines and containers. This can be done by enabling HA in the settings for each virtual machine or container.

• Configure load balancing settings for the cluster. This can be done by setting up load balancers and configuring the cluster to use them.

• Monitor the cluster for performance and issues using the Proxmox web interface or CLI.
