September 2014 - dev - Rdo List Archives

by John Eckersberg

(In the spirit of "Concerning Hobbits") Ryan O'Hara and I have been investigating RabbitMQ as it pertains to RDO recently. There has been a lot of discussion on several disparate threads, so I wanted to try and capture it on the list for the benefit of everyone. Ryan has been working on getting RabbitMQ running in a multi-node HA configuration. I won't steal his thunder, and he can speak to it better than I can, so I'll defer to him on the details. As for me, I've been working on el7 support and bug squashing along the way. The first bug[1] causes the daemon to load incredibly slow, or outright fail by timing out. This is due to the SELinux policy disallowing name_bind on ports lower than 32768. RabbitMQ tries to name_bind to a port starting at 10000, and increments if it fails. So if you have SELinux in enforcing mode, you'll get 22768 AVC denials in the log before it finally starts. The second bug[2] causes the daemon to intermittently fail to start due to a race condition in the creation of the erlang cookie file. This happens only the first time the service starts. Really this is an Erlang bug, but there's a workaround for the RabbitMQ case. I've submitted patches for both issues. Until those get merged in, I've rebuilt[3] RabbitMQ for F20 which includes the fixes. Beyond bugs, I've also built out RabbitMQ and all the build/runtime dependencies for el7. I have a yum repo[4] on my fedorapeople page containing all the bits. This is all the stuff that is presently missing from EPEL7. In time, I would hope the maintainers build all this stuff, but for now it'll work for testing. You will also need the EPEL 7 Beta repository[5] enabled. As a side note, I built everything using mock with a local override repo on my workstation. I've not used copr before but it seems relevant to this sort of thing, so if it's any benefit I'll look to rebuilt the el7 stack there for easier consumption. Hopefully this helps get the discussion into one place, and provide a baseline for further investigation by everyone interested in RabbitMQ. John. --- [1] Is really two bugzillas, but the same bug: [1a] https://bugzilla.redhat.com/show_bug.cgi?id=998682 [1b] https://bugzilla.redhat.com/show_bug.cgi?id=1032595 [2] https://bugzilla.redhat.com/show_bug.cgi?id=1059913 [3] http://jeckersb.fedorapeople.org/rabbitmq-server-3.1.5-3.fc20.noarch.rpm [4] http://jeckersb.fedorapeople.org/rabbitmq-el7/ [5] http://dl.fedoraproject.org/pub/epel/beta/7/x86_64/

[Rdo-list] python-sqlalchemy is removed in epel

by Liping Mao -X (limao - YI JIN XIN XI FU WU(SU ZHOU)YOU XIAN GONG SI at Cisco)

Hi , I find that python-sqlalchemy is removed from EL7, and in Juno repo, we have this rpm. https://repos.fedorapeople.org/repos/openstack/openstack-juno/epel-7/ But in icehouse for EL7 we do not have this. https://repos.fedorapeople.org/repos/openstack/openstack-icehouse/epel-7/ I think it will make packstack not work for icehouse EL7. Icehouse EL7 works for me a few days ago, python-sqlalchemy is installed from EL7 at that time: [root@rcehouse-rdo-centos7 ~]# yum list installed python-sqlalchemy Loaded plugins: fastestmirror, priorities Loading mirror speeds from cached hostfile * base: centos.mirror.facebook.net * epel: mirror.nus.edu.sg * extras: holmes.umflint.edu * updates: mirror.acsnet.com 18 packages excluded due to repository priority protections Installed Packages python-sqlalchemy.x86_64 0.8.4-1.el7 @epe Should python-sqlalchemy also be added in icehouse repo? Thanks. Regards, Liping Mao

[Rdo-list] Create a link rdo-release-juno.rpm rdo.fedorapeople.org

by Christian Berendt

At https://review.openstack.org/#/c/123837/ we have the problem that we want to document the usage of https://rdo.fedorapeople.org/rdo-release.rpm for a specific release. At the moment this is not possible because https://rdo.fedorapeople.org/rdo-release.rpm always points to the latest stable release. Is it possible to cretae an additional link named rdo-release-juno.rpm pointing to the latest available repository package? rdo-release.rpm --> rdo-release-juno-1.noarch.rpm rdo-release-juno.rpm --> rdo-release-juno-1.noarch.rpm rdo-release-icehouse.rpm --> rdo-release-icehouse-4.noarch.rpm This way we do not have to update the documentation after the release of a new repository package and we have working links in older documents of stable releases after a new release. For example the links in http://docs.openstack.org/icehouse/install-guide/install/yum/content/ will not work after the release of Juno.

A reminder that we'll be doing a test day for Juno Milestone 3 next week, October 1 and 2. Details are at https://openstack.redhat.com/RDO_test_day_Juno_milestone_3 The test case page - https://openstack.redhat.com/RDO_test_day_Juno_milestone_3_test_cases - is still looking kind of sparse, and this would be a great place for folks to jump in with suggestions of the kinds of scenarios that we want to test.
