Node.JS not starting on all Virtualmin cluster nodes

Running 2 virtualmin servers, with shared storage on NFS to host multiple PHP based websites and it’s working fine. We create the site(s) on server-1 and use the CLI to keep config in sync between the 2 servers.

virtualmin transfer-domain --domain example.org --host server-2 --replication --output --overwrite

Now we need to deploy a NodeJS application and it seems to work fine on server-1 and the nodejs service is started.

But after a sync from server-1 > server-2 we are not able to start the nodejs service on server-2. I am using the same command as before.

virtualmin transfer-domain --domain nodejs.example.org --host server-2 --replication --output --overwrite

Is this setup not supported on Virtualmin or do i need to create the config in a different way?

Thanks.

Okay, I have done some more digging.
It seems that the issue is that the

virtualmin transfer-domain --domain nodejs.example.com --host server-2 --replication --output --overwrite

Does not create the needed systemctl services.

After a replication I created the service on server-2 manually using the same config from server-1

systemctl edit --full --force nodejs-nodejs.example.com-3000.service
systemctl daemon-reload
systemctl enable nodejs-nodejs.example.com-3000.service --now

Then it worked. even after a replication the services are still running.

So maybe this could be a thing to add to the replication feature of virtualmin ?

Kind regards.

@Jamie, is this something you have already fixed for upcoming Virtualmin 7.40.0?

Does the same thing happen if you create a test domain with node.js, back it up, delete it, and then restore the backup?

[combine1]

Sorry for the late reply.

I did the following to test.

Deleteded the replicated site on server-2, the systemctl service was not removed, then again i created it manually.

Did a backup of the site on server-1 and restored it on server-2 and the service is also restored at server-2.

Hope that help else let me know

If you just create a domain and install node.js, does a systemd service to start the node server get created?

And then if you just delete that domain, does the systemd service get removed as well?

[combine1]

If I create the NodeJS with the script installer it creates the service, if I then delete the NodeJS via the script installer it removes the service.
If I delete the site entirely it also removes the service as expected.

Only when I use the CLI to replicate it does the service not work on the destination host.

Only when I use the CLI to replicate it does the service not work on the destination host.

So the replication basically just does a backup on one system and a restore on the other. If you do this manually, does the Node.JS systemd action get created?
