I am trying to connect two local regtest nodes together. I am able to run one regtest node without any issues, and am also able to run the bitcoin-cli commands such as generate to create my own chain, however when I try to start a new node, I'm not able to connect them. This is what I do (sorry if there is a clear mistake).
Run node 1
./src/bitcoind -regtest -port=8333 -rpcport=8332 -datadir=/Documents/node1data -conf=Bitcoin/bitcoin.conf
Run node 2
./src/bitcoind -regtest -port=8330 -rpcport=8331 -datadir=/Documents/node2data -conf=/Bitcoin/bitcoin.conf
By now I seem to have two different chains, generating blocks on one node doesn't change the number of blocks in the other node. I would like to have these two nodes share a chain so that mining a block in one of the nodes updates the chain on both of them. However when I try to connect them using the following command:
./src/bitcoin-cli -regtest -port=8333 -rpcport=8332 -rpcuser=user -rpcpassword=password addnode "http://127.0.0.1:18332" "add"
The rpc call to addnode displays no errors and if I run it again I get: "Error: Node already added"
After this call, the command
./src/bitcoin-cli -regtest -port=8333 -rpcport=8332 -rpcuser=user -rpcpassword=password getconnectioncount
returns 0...
So, I see a lot of people using software such as dockers, etc. Why is this not working? Am I completely mistaken to think this could work, if so I would love to know where I'm failing. Ultimately, how can I achieve to have two or three nodes connected to each other?
Thanks in advance to anyone who reads my question.
