I've had a number of rounds of trying to get the latest Aegir beta installed. I was getting a "can't connect to master database" error. Weird, since I could connect to the db at localhost and the FQDN.
So, I started to poke around and saw the my .drush folder contained the files:
- server_localhost.alais.drushrc.php
- server_master.alias.drushrc.php
Those files had stale info in them. I'd evidently run the install.sh script enough times and made changes in between that something was amiss.
The fix? Deleted my .drush folder and re-ran the install.sh script. Voila!
Next, I'm planning on trying to work (carefully) with remote web and db servers I use for prod and dev environments.
