Hi I want to start with RDO installation. For my work I would need ceilometer too. Which is the most stable version of to support it? Also I would like to know what services are provided in RDO like does it use neutron or legacy nova networking architrecture?

Does it use GRE tunneling for neutron? Also mine will be a multi node installation with one server as controller+neutron and three other servers as compute nodes. GRE causes a lot of CPU overhead.

i recommend you to use the answerfile option... this could save you a lot of headaches when running the allinone installation again (passwords, configuration, etc...)

--allinone Shorthand for --install-hosts=<local ipaddr=""> --novanetwork-pubif=<dev> --novacompute-privif=lo --novanetwork-privif=lo --os-swift-install=y --nagios-install=y , this option can be used to install an all in one OpenStack on the host

During the last week I ran packstack --allinone on daily basis due to testing Nova-Docker.git branch for Juno. It runs silently and never asked me any question. Yes it installs swift && ceilometer, which might disabled via editing GEN_ANSWER_FILE.

Editing GEN_ANSWER_FILE requires experience and usually is used for RDO Multinode deployment. It might be using for temporary workarounds , view http://cloudssky.com/en/blog/OpenStac...

You may start here https://openstack.redhat.com/Quickstart
with packstack --allinone Juno install on F20 or CentOS 7. Ceilometer will be installed for you.
RDO Juno (IceHouse) support only Neutron, Nova-networking was deprecated on RD0 , I would guess since Havana release. Service installed :-

In meantime it uses by default VXLAN tunnelling for both AIO && Mutinode Deployment
Regarding your need in "one server as controller+neutron and three other servers as compute nodes" , there is ready and tested solution , described in details here ( for one Compute Node)
http://lxer.com/module/newswire/view/...
To update answer file for "three compute nodes" , change only one line in answer-file:-

CONFIG_COMPUTE_HOSTS=192.168.1.137,192.168.1.147,192.168.1.157

Just ignore the part related to Gluster and (or) LVMiSCSI back-ends cinder configuration.

Ok. Thanks a lot :)

Thanks. If I do not want cinder I just need to do CONFIG_CINDER_VOLUMES_CREATE=n in answer file? How to disable swift? Also how to enable heat?

fresher gravatar imagefresher ( 2014-12-22 06:46:24 -0500 )edit

Answer updated with HEAT instructions .

CONFIG_SWIFT_INSTALL=n
CONFIG_CINDER_INSTALL=n
dbaxps gravatar imagedbaxps ( 2014-12-22 07:03:05 -0500 )edit

Would heat not work with

CONFIG_HEAT_INSTALL=y

Also, I will have to install f20 server version on all the servers?

fresher gravatar imagefresher ( 2014-12-22 07:54:12 -0500 )edit

Install f20 servers is not a problem.

CONFIG_HEAT_INSTALL=y should work
