I am trying to learn about clusters.
So far I have created a GPLVirtualmin server and a Webmin server.
They both can (only) communicate with each other via ssh-keys.
On the Vmin server, Webmin Servers Index and created a server for the Webmin system which works in that it can auto log into the webmin server with a single click.
Then on the Vmin server I went to Cluster Users and Groups and created a Managed Server as the Vmin server (self) which would be the master (so I have read).
But, there is no option now to add another server. I have tried and read a lot, it all suggest that there should be an option to add another server, but if it exists then I canât find it.
Any help appreciated. The purpose if for creating/editing/deletin users on a Vmin server to be replicated on the Webmin server.
Before this module can be used to manage another systemâs software, that system must be added to its list of servers. To do this, follow these steps:
Use the Webmin Servers Index module to add the remote system, and make sure you provide a username and password. This does not have to be done if you want to manage the master server though.
In this module select the system from the menu next to the Add server button and then click it. The menu will usually include the special entry this server, which is the master system. It will never include any servers that have already been added though. Alternately you can select an entire group of servers from the menu next to Add servers in group. Groups can be defined in the Webmin Servers Index module as well.
Asa mentioned, I added the remote Webmin server to the master Vmin server.
It then suggest add the master and there should be a special entry âthis serverâ which is nowhere to be seen.
A page showing all of the hosts added and the number of packages on each will be displayed. If a host cannot be contacted or the RPC login fails, an error message explaining what went wrong for that host will appear instead.
Return to the moduleâs main page, on which a new icon for each host should now be listed.
This to me doesnât make sense. We are still in Webmin Servers Index and I donât see anything about the number of packages.
Then returning to the modules main page - which is where you already are, so how do you return?
Reading further, it doesnât mention going to the Cluster section - which is where you can see all the packages on a remote server, but doesnât allow me to add a remote server.
Thanks, but while the docs say to use that to add a remote server, Webmin Servers is for a different function to Webmin clusters, and at least in my case, after adding a webmin server it didnât show up in the Cluster section.
You seem to be making a mountain out of a mole hill, take a step back and just experiment with clustering, if your systems are setup well clustering wonât hurt the running servers. Learn to walk before you run
I have already spent a day on this, trying to make sense of it all. I donât ask on the forum unless I have read all I can find and tried all the options.
Truth is that the docs here are a bit of a mess, no clarity. Perhaps written for experts whereas to be helpful they really need to be written for people without this specific experience.
Webmin â Webmin Servers Index is where you add your new server Cluster â Cluster Webmin Servers is where you add a server to the cluster
so are you trying to add a third webmin server ?
This has nothing to do with clustering, just use a privileged webmin user to login with, remember this is not using ssh to communicate itâs using webmin
