Hello friend
Welcome to my video
In this video
I show you how to configure high availability for your virtual machine with Proxmox
That is, when a virtual machine crashes,
It will be replaced with another virtual machine and ensure the services are still working properly.
To do that
The following requirements are required
At least three cluster nodes
shared storage for VMs
Currently
I have 3 Proxmox nodes pre-installed
In the previous video I showed you how to install Proxmox step-by-step
You can also find it in the description of this video
Under Datacenter then click Cluster, click on Create Cluster
Enter the cluster name
Adding Nodes to the Cluster. Login to the web interface on an existing cluster node
Under Datacenter then click Cluster, click the button Join Information at the top.
Then, click on the button Copy Information
Next, login to the web interface on the node you want to add.
Under Datacenter then click Cluster, click on Join Cluster
Fill in the Information field with the Join Information text you copied earlier. Most settings required for joining the cluster will be filled out automatically
For security reasons, the cluster password has to be entered manually
the cluster password has to be entered manually
After clicking the Join button, the cluster join process will start immediately
You might then need to force-reload the web interface and re-login with the cluster credentials
Now your node should be visible under Datacenter then click Cluster
Next, create ZFS
Under Node1 then click Disk, choose ZFS then click create ZFS
Enter the ZFS name
Continue execution on node 2. Note uncheck Add Storage
With node 3, you do the same thing as node 2
You do the same thing as as node 2
Next configure storage
Under Datacenter then click Storage
choose the ZFS storage you just created then edit it
You select all 3 nodes then click OK
Next create a new virtual machine on node 1
After creating the virtual machine on node 1, you perform configure replication on node 2 and node 3
Select the newly created virtual machine then click replication then click Add
You replication to node 2 and node 3 . respectively
respectively
Next
Next, configure high availability
Under Datacenter then click HA then click Add
Then select your virtual machine just created
Necessary configuration steps you have done, now what happens when something goes wrong
now what happens when something goes wrong
I will shutdown node 1 , and we'll see what happens
After waiting for a while you will see that the virtual machine will automatically switch from node 1 to node 2
I hope this video help you configure high-availability with Proxmox
