Issues Installing ejabberd on AWS

2
votes

I am trying to install ejabberd on a EC2 AWS Linux 2 machine running on a public subnet. I did the following:

  1. Assigned the EC2 instance an Elastic IP (52.22.184.194)
  2. Assign this domain to the the EIP - ejabberddev.strax.co
  3. Changed the hostname of the machine to ejabberddev.strax.co
  4. ejabberd is installed.

  5. I get the error:

    20:55:32.313 [error] Failed to open socket at 52.22.184.194:7777 for mod_proxy65_stream: can't assign requested address

  6. ejabberd is trying to open a socket using the AWS elastic IP address - this will not work.

  7. I went into the ejabberd.yml file and added the ip variable to get ejabberd to use the AWS private ip for the macine.

    mod_proxy: 
  ip: 10.1.254.240
  access: local
  max_connections: 5

  8. This fix and issue the ejabberd was able to come up.

  9. For some reason the user I entered at install time admin and the domain ejabberddev.strax.co was not in the database so I entered it using this command.

    ejabberdctl register admin ejabberddev.strax.co admin

  10. This seemed to work so I tried to login into the web using these credentials and the URL containing the domain http://ejabberddev.strax.co:5280/admin

  11. When I logged in the following error happened:

Not sure what is error means. Based on the fact I cannot even install the ejabberd package and login in I think something is going wrong regarding the use of AWS elastic IPs. I have not found any document about installing ejabberd on AWS - any help will be appreciated.

This bug was introduced in ejabberd 20.02 when implementing other stuff, and right now is only fixed in git: https://github.com/processone/ejabberd/commit/00abf5d42c9b9c979b7ac69758a8f6745744f929

You can either apply that fix into your source code, or go back to previous ejabberd version, or wait for the next version.
