Puppet users - Feb 2012 - Questions regarding Puppet with httpd.conf

Hi,

I''d like to start using Puppet to manage an httpd.conf file across
several webservers. I have a Puppet server and client config setup and
have followed a couple of simple "How To''s" to get off the
ground. I''m
syncing a couple of files and ensuring certain packages are installed
etc on the client.

Now, here ''s where I''m stuck... what happens if the httpd.conf
file is
slightly different on each webserver? For example, each httpd.conf
file has multiple Virtual Host entries that are defined by the
webservers IP. <VirtualHost 10.3.200.131:80> for example.

How do I manage one httpd.conf file from the Puppet server given the
VirtualHost IP''s will be different on each server? I guess I just want
to "taylor" the http.conf file for each weberserver but manage it from
the Puppet Server.

If anyone can give me a few pointers it would be appreciated.

Thanks,

You''ll want to look at
http://docs.puppetlabs.com/guides/templating.html

You can use a template and have it fill in variables.  Luckily, the
host''s IP address is already available as a variable via facter.

Further, you should remember that there is no reason for an Apache
configuration to be monolithic.  Apache is perfectly happy to have a bunch
of files to include.  Throw in a naming convention (e.g. files named
foo.ssl will be included by my SSL config file) and you''ve got some
real
flexibility.

Others have already correctly steered you towards templates for this sort
of thing, but I have one aside...

Just like to point out that, unless you have specific reason for binding
apache only to one interface, it''s perfectly acceptable to throw
wildcards
in to these declarations (ie. software virtual hosting versus hardware). It
has the added effect of simplifying configurations (though, as I hinted at
previously, there may be other security related implications or similar
that prevents you from doing this sort of thing).

Thanks for the replies, they were very helpful. I''ll post back if I
have any problems.
