Using Ansible to provision simple Rails server

  • Posted February 23, 2014

Hey,

I am trying to use Ansible to provision a simple Rails server with nginx, passenger, rails and postgresql.

I have copied my SSH key over to the VPS and I can see it in ~/.ssh/authorized_keys but when I navigate to the directory on my local machine where I have my Ansible setup and playbooks and run ansible all -i hosts -m ping I get:

<ip> | FAILED => SSH encountered an unknown error during the connection. We recommend you re-run the command using -vvvv, which will enable SSH debugging output to help diagnose the issue

I rerun with -vvvv and get a huge amount of debug info. I’m not quite sure which part to post here so this is a bit I feel is the most important:

debug2: kex_derive_keys debug2: set_newkeys: mode 1 debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug2: set_newkeys: mode 0 debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug2: service_accept: ssh-userauth debug1: SSH2_MSG_SERVICE_ACCEPT received debug2: key: /Users/<me>/.ssh/id_rsa (0x7f8253000360), debug2: key: /Users/<me>/.ssh/id_dsa (0x0), debug1: Authentications that can continue: publickey,password debug3: start over, passed a different list publickey,password debug3: preferred gssapi-with-mic,gssapi-keyex,hostbased,publickey debug3: authmethod_lookup publickey debug3: remaining preferred: ,gssapi-keyex,hostbased,publickey debug3: authmethod_is_enabled publickey debug1: Next authentication method: publickey debug1: Offering RSA public key: /Users/<me>/.ssh/id_rsa debug3: send_pubkey_test debug2: we sent a publickey packet, wait for reply debug1: Authentications that can continue: publickey,password debug1: Trying private key: /Users/<me>/.ssh/id_dsa debug3: no such identity: /Users/<me>/.ssh/id_dsa: No such file or directory debug2: we did not send a packet, disable method debug1: No more authentication methods to try. Permission denied (publickey,password).

Any ideas on how I can solve this?

Kind regards, Neil
