Thanks for the suggestions! The ami I've been mainly using is ami-da58aab3 (although I've tried a few others). The user data may be where I am messing up: I have a few questions I'm not clear on, I think I've tried may options here.. 1. Is cluster name just something I make up? 2. Are the <> characters part of the yaml structure? (I've tried both). 3. Do I need to specify the default information? I've tried: cluster_name: galaxy_cloud_cluster password: apassword access_key: mypublickeyblahblahblahblab secret_key: myprivatekeyblahblabhalbahblahblah I've also tried with the <> cluster_name: <galaxy_cloud_cluster> password: <apassword> I've also tried adding the other information... boot_script_name: [cm_boot.py] boot_script_path: [/tmp/cm] bucket_cluster: cm-<hash> bucket_default: [cloudman] cloudman_home: /mnt/cm [master_ip: <*exists only if worker*; master internal IP address>] role:<master or worker> [testflag: False] On apache: I totally understand it's not part of any of this, I was just trying that to see if I could access through http (I was just trying things to narrow down where the problem is). Here's an attempt at an output from py.log, I hope I have it all. Thanks for working through this with me! ubuntu@ip-10-204-103-174:/opt/galaxy/pkg$ cat ec2autorun.py.log [INFO] ec2autorun:38 2011-09-27 07:09:50,922: Getting user data from 'http://169 .254.169.254/latest/user-data', attempt 0 [DEBUG] ec2autorun:42 2011-09-27 07:09:50,938: Saving user data in its original format to file '/tmp/cm/original_userData.yaml' [DEBUG] ec2autorun:46 2011-09-27 07:09:50,938: Got user data [INFO] ec2autorun:284 2011-09-27 07:09:50,938: Handling user data in yaml format [DEBUG] ec2autorun:317 2011-09-27 07:09:50,940: The provided user data does not contain bucket_default field; setting it to 'cloudman'.
