Hi,

I have several git repos to manage changes to different environments (say  
DEV + PROD). Is it pretty straight-forward to run chef-server on different  
ports and have the DEV clients connect to the DEV port and PROD to the PROD  
port? Will I need to configure different rabbitmq queues and couchdb  
database for each one?

If any has pointers to docs (Google hasn’t help here) or has experience  
doing this I’d appreciate it.

Thanks,  
Mark

I'd start here: [http://wiki.opscode.com/display/chef/Chef+Configuration+Settings](http://wiki.opscode.com/display/chef/Chef+Configuration+Settings)

The trick is that you'll need to be running two of everything. You can  
make decisions like two couchdb servers or one with two databases, and  
two rabbitmq servers or one with multiple vhosts? Theoretically you  
can set all this. If you do it, I'd love to hear your success. I'd  
personally just run two VMs because it leaves you with a more standard  
installation that is easier to scale.

Hi Bryan, that's pretty much what I thought but wanted to check my idea  
before starting to install and configure (and suffer debugging pains 🙂 ).  
I'm not expecting _many_ clients, fewer that 100, so I think I'll go with  
one each of couchdb and rabbitmq and use multiple databases and multiple  
queues.

I can't run 2 VMs, because:  
a) I'm running in an EC2 instance and cannot further virtualize 🙂  
b) I really simplified the question and have other environments (QA, UAT,  
etc.) in between DEV and PROD. I can't afford that many servers for this  
project.

Cookies if you do this with chef-solo and release your cookbook when  
you're done.

OK, I'll try and tackle solo mode once I have this env up and running.

First dumb question: is there a way to point chef-server at a different  
server.rb than the one in /etc/chef? I did chef-server --help but couldn't  
find any options for that.

Thanks,  
Mark

Does this also mean I need multiple solr servers, each on a different port?

You need multiple Solr instances. Not necessarily different ports, if you set it up as multiple contexts on a single tomcat (or what have you).  
I'd like to hear about your experience too.

I promise to document what I find :), it's the least I can do for all your  
kind help on the list.

When I try and start the chef-server I get the following error (cryptic)

Hi folks, any ideas? Any ideas about how to go debugging this?

Thanks,  
Mark

Looks like a failure to connect to Rabbitmq; the error message is  
uglier than it could be (I have bunny-0.7.9 where the failure is  
handled better).  
Did you confirm it is indeed running on port 5672? Also, I see the  
host is 0.0.0.0.  
Depending on your OS and the phase of the moon, that may be different  
from 127.0.0.1; try that one.

Hi Andrea,

I checked with netstat and it looks like it is on the right port; as for  
the Host=0.0.0.0 I don't yet know where it's getting that. Still looking ..

[https://github.com/celldee/bunny/issues/21](https://github.com/celldee/bunny/issues/21) suggests it may be an  
authentication error.

Refer to [http://wiki.opscode.com/display/chef/Chef+Indexer](http://wiki.opscode.com/display/chef/Chef+Indexer), it has a  
nice "checklist" you can use to verify rabbitmq is set up correctly.

Thanks Andrea, awesome links; following the Chef Indexer list fixed the  
problem, somehow. I suspect by forcing me to clean up my broker and  
restarting the instance.

Well, it -was- going pretty well; I got one server up and running from a  
repository and, while getting the second one going, I'm running into  
certificate issues. Which highlights to me that I don't know enough about  
how certificates are generated and consumed in the Chef architecture. Are  
there any good pointers to documentation on this?

What kind of certificates? They're used for client authentication,  
which is briefly described here:  
[http://wiki.opscode.com/display/chef/API+Clients](http://wiki.opscode.com/display/chef/API+Clients)

Make sure you set the path to the validation\_key to a different value  
for each server. This is the special client that can be used to  
automate creating new clients. If the file specified by validation\_key  
does not exist it is recreated, but keep in mind that client keys are  
actually stored internally in the database. This file on the server is  
mostly a convenient way for you to get a couple of the validation  
clients key. See  
[http://wiki.opscode.com/display/chef/Chef+Configuration+Settings#ChefConfigurationSettings-certificatesettings](http://wiki.opscode.com/display/chef/Chef+Configuration+Settings#ChefConfigurationSettings-certificatesettings)

Thanks again for the links, they helped get me (initially) past the  
certificate issues.

I'm trying to start the webui and, although it seems to start correctly, I  
cannot seem to log in when presented with a login form. My chef-server is  
on port 4020 and the webui is on port 4050.

Which step is responsible for populating the database with the initial  
admin user?

Mark

OK, I found the setting apqp\_host and set it to 127.0.0.1 with no effect  
(that is, still getting the error).
