Hello,
Great work with the Galaxy on the Cloud - it's the first time I've used it
and it looks very impressive (and I'm not a big cloud fan :) ).
Thank you very much for the comment!
Once I got it working it was very nice, but before it worked I encountered
two issues (not sure if those were voodoo or not) that could be perhaps
documented in the Wiki (under troubleshooting?):
1. the User Data is sensitive to trailing white-space, or senstive to
copypaste in the edit box.
I accidentally had:
access_key: XXspacespace
and it seems it completely prevent the Cloudman from starting.
when the stared, I couldn't connect to it with a web-browser.
I logged on using SSH, and saw that there was nothing running/listening on
port 80 (no nginx, no python).
Not sure exactly why it happened, but it did.
removing white-space (and also saving the user-data to a file instead of
pasting it directly in the editbox) solved the problem.
Noted and will be fixed before the next update.
You may also consider using biocloudcentral.org as a quick way to starting
up CloudMan clusters without having to worry about the formatting of the
user data.
2. If the user-data password is all numeric, there's no way to login to
the cloudman.
I suspect the reason is that an all numeric password is treated as a
number, not a string.
Then, the log shows:
$ cat /opt/galaxy/pkg/ec2autorun.py.log
[...]
[DEBUG] ec2autorun:337 2012-04-13 20:22:50,983: Composed user data:
{'access_key': 'XX', 'cloudman_home': '/mnt/cm',
'cluster_name': 'galaxy-TGAC-workshop', 'bucket_default': 'cloudman',
'role': 'master', 'bucket_cluster': 'cm-169ca4be88c386ce8ec3078d69a6dc3a',
'boot_script_path': '/tmp/cm', 'boot_script_name': 'cm_boot.py',
'secret_key': 'X', 'password': 12345678}
[...]
you'll notice that the password key is a numeric value, not a string - and
login wasn't possible (perhaps it was voodoo and I'm wrong in my guess, but
once I changed it to alphanumeric password, with the same user data
settings, it workd).
Will be fixed as well.
Thanks again for reporting these issues,
Enis
