Idjit's Guide To Installing RabbitMQ on openSUSE 12.1

The RabbitMQ team provides a generic SUSE RPM which works on openSUSE 11.x, openSUSE 12.1, and I presume on the pay-to-play versions of SuSE Enterprise Server. About the only real dependency for RabbitMQ is the erlang platform which is packages in the erlang language repo. So the only real trick is getting the RabbitMQ package itself [from this page].  Then install and start is as simple as:

zypper ar http://download.opensuse.org/repositories/devel:/languages:/erlang/openSUSE_12.1 erlang
zypper in erlang
wget http://www.rabbitmq.com/releases/rabbitmq-server/v2.8.1/rabbitmq-server-2.8.1-1.suse.noarch.rpm
rpm -Uvh rabbitmq-server-2.8.1-1.suse.noarch.rpm
service rabbitmq-server start

Now you probably want to do some configuration and provisioning using the rabbitmqctl command; but your RabbitMQ instance is up and running.

Update 2012-04-10: Updated these instructions to install RabbitMQ 2.8.1.  The later 2.7.x series have start-up script issues as those scripts use the "runuser" command which is not present on openSUSE.  Running the latest RabbitMQ is generally a good idea in any case,  recent versions have corrected several memory leaks and manage resources more efficiently.

Disabling GNOME Automount

When you connect a mass storage device to a computer running the GNOME desktop environment it automatically mounts the device in /media and places a short-cut to the device on your desktop.  This is an excellent default behavior;  but if you are working with various devices sometimes it can get in the way.  To correctly disable this feature simply execute:

gconftool-2 --type bool --set /apps/nautilus/preferences/media_automount false

The devices will still appear in computer:/// (in nautilus) where you can right click on them to select the mount action if and when you want them to be mounted.  If and when you want to re-enable to auto-mounting feature execute:

gconftool-2 --type bool --set /apps/nautilus/preferences/media_automount true

Packages Complete

OpenGroupware packages have been completely built on the build service for CentOS5, Fedora 9, openSUSE 10.3, RHEL 5, and SLES10. The Fedora 10 and openSUSE 11.x packages needs some additional work.

Repositories at:

• CentOS 5
• Fedora 9
• Fedora 10
• openSUSE 10.3
• openSUSE 11.0
• openSUSE 11.1
• RHEL 5
• SLES 10

Initial testing on CentOS 5 seems pretty positive, after a:
$ yum install ogo-meta ogo-database-setup

Only glaring bug is that ogo-database-setup doesn't actually populate the database schema so that still needs to be done by hand:

$ cat pg-build-schema.psql | psql -h localhost -U OGo OGo

Then restarting the services gives you [as far as I can tell so far] a fully working OGo install.

P.S. Make sure your getting the most current packages from the repository. mod_ngobjweb in particular should be dated March 4th; with the previous version the web resources (icons, etc...) for the WebUI won't be found at the configured path.

Almost there

The ogo-meta package now almost installs on CentOS5 except that we don't have the ogo-environment or the ngobjweb packages. OpenSUSE 11.0 and 11.1 have some problems building anything beyond ogo-gnustep_make; OpenSUSE 10.3 builds up to the same point as CentOS5.

openSUSE 10.2 & gcc-objc

Neither the openSUSE 10.2 CDs nor the DVD image contain the the gcc-obj or the libobjc packages required to compile and run Objective-C applications such as OpenGroupware. I'm led to believe that the commercial DVD does contain more packages as it is multi-layered.

Fortunately this oversight is easily remedied; you just need to add the online package repository as an installation source. Go into YaST / Software / Installation Source, then add an HTTP source with a "Server Name" of "download.opensuse.org/distribution/10.2/repo/oss/". This is the default package repository for all Open Source packages provided with openSUSE 10.2. Clicking "Next" will then cause YaST to thrash around for awhile as it downloads what it needs to support the installation source. After prompting for acceptance of the same license agreement you accepted when installing the distribution the channel should be available.

Searching in Software / Software Management you should now find three Objective-C related packages: gcc41-objc, gcc-obj, and libobjc41. Only the latter is required to run Objective-C applications.

Once libobjc41 is installed then the OpenGroupware packages for OpenSuSE 10.0 will install and run.
