Can you run multiple nodes on the same server?
Both nodes start, using different terminals/users. On one user (initial user) the cli allows me to query through getinfo. The other gives an error: The password of the rpcuser in ~/.multichain/chain1$ more multichain.conf is different for both users, which is ok?
What happens if both miners get the same address?
If both miners are getting work from the same node, then the node will never assign both miners the same work. If both miners are getting work from different nodes, then they will get different ephemeral addresses. (If I recall correctly, at one time addresses were reused for mining.
When do you keep using the same address?
You don’t keep using the same address. You generate an ephemeral address and, if you mine a block, you keep its private key and then start using a new address. If both miners are getting work from the same node, then the node will never assign both miners the same work.
Do you need two addresses for solo mining?
As far as I know, you can configure your 2 solo-mining computers to either use each their own address or one for both. And no: even if both were using their own addresses and working independently, the processing power of the slower one is not completely wasted.
Can a node server be run as root?
Option 1 requires you launch the node server as root. Not ideal. Option 2 adds overhead to every handled request and adds another failure point to your stack. Option 3 Is the simplest and most efficient method.
Can you run Node Manager as a startup service?
For more information, see Running Node Manager as a Startup Service. On UNIX platforms, Oracle does not recommend running Node Manager as the root user. However, to achieve Post-Bind GID, you must start Node Manager as the root user.
What do you need to know about managed nodes?
When logged in as a regular user, you may be required to perform certain tasks on managed nodes that require elevated privileges or root privileges. These tasks include package management, adding new users & groups, and modifying system configurations to mention just but a few.
