You could try something like monit to monitor it and restart it when needed.
If you mean a completely new server, that would be somewhat more complicated, but probably something like AWS' tools would be helpful, depending on your host.
I have a question , may you guys can guide me
I have a node that works with almost no problems , occasionally bitcoin daemon stops working.
I would like to open a second node, which became operational only when the first process to stop working .
Any ideas? I think the pools use this system .
Anyone have a script to go by checking if the demon of BTC is working? and if not will run the backup
Thanks
