 erl -sname ejabberd \

-mnesia dir '"/var/lib/ejabberd/"' \

-mnesia extra_db_nodes "['ejabberd@first']" \

-s mnesia

On First Node error occurs -

Finally , I solved my problem. The problem is with Erlang OTP version. I was using Ejabberd 13.12 and Erlang OTP 15B1 . Inspite this combination is working good in local network but not working on AWS EC2. Now I Have replaced Erlang OTP version with OTP 17 and my cluster is working fine.

It is best to clear your local database files and have ejabberd regenerate them after you have set up host names, etc.

I have got my cluster running by following this guide up to step 5 on both nodes, then (since I did not want to use this custom module for database sync) I went to the guide you mentioned and did the database sync manually as you are currently trying to. (It still took me half a day to trace all errors, but with the above mentioned guides and googling error messages from the log files it finally worked out. ;) )
