I am having problem adding servers to a cluster or create reference to remote cluster in Couchbase. I’ve created to EC2 Windows 2008 servers on Amazon in the same region and zone. I’ve installed Couchbase on each machine and the server is running fine. I’ve opened all the ports in the Security Groups just for testing.
When I try to add a server I get the following error in the ‘Add Server’ window:
Attention – Failed to reach erlang port mapper. Timeout connecting to
“54.243.156.39” on port “4369”. This could be due to an incorrect
host/port combination or a firewall in place between the servers.
I’ve used the same username and password on both. The connection problem happens even when I want to add a server to a current cluster when I first configure the server.
- I’ve installed the couchbase 2.0 beta
- the EC2 servers aren’t in cluster, they are single EC2 machines
Any help on this.
It seems you have problems with Erlang port mapper daemon (epmd) (which allows node to node communication), because your firewall block this port by default. You should open it manually. In firewall settings click allow program, then add port and in the port number field enter the port number 4369/tcp.
And just in case check and configure your IP tables by netsh advfirewall command.
Hope this helps.
