How to access mnesia in remote server

I have an application built on Erlang/cowboy, the database is mnesia. The node name is [email protected].

Since there is no GUI in remote server, I want to use local observer to access to the remote mnesia.

I tried many times, but still failed. Can anyone help me out? (Assume the IP of remote server is 10.123.45.67)

Solution

  • Your remote Erlang node name should be [email protected] instead of [email protected].

    Also you need to set the same cookie for both nodes as well as the same node naming convention. By naming convention I mean short name (-sname flag) or long name (-name flag), becuase a node with a long node name cannot communicate with a node with a short node name.

    Note that if your real remote IP is not in a trusted network, it is not good practice to do it in case of security.
