<br>
<br>
<br>
Sure! Here we go...<br>
<br>
Upgrading from IceHouse to Juno on Ubuntu 14.04.1.<br>
<br>
-----<br>
1- Stop all OpenStack services on each node, right before running the<br>
upgrade procedure;<br>
<br>
</span>Â service keystone stop<br>
 cd /etc/init/; for i in $(ls neutron-* | cut -d \. -f 1 | xargs);<br>
do sudo service $i stop; done<br>
<br>
 cd /etc/init/; for i in $(ls nova-* | cut -d \. -f 1 | xargs);<br>
do sudo service $i stop; done<br>
 cd /etc/init/; for i in $(ls glance-* | cut -d \. -f 1 | xargs);<br>
do sudo service $i stop; done<br>
 cd /etc/init/; for i in $(ls cinder-* | cut -d \. -f 1 | xargs);<br>
do sudo service $i stop; done<br>
 cd /etc/init/; for i in $(ls heat-* | cut -d \. -f 1 | xargs);<br>
do sudo service $i stop; done<br>
 ...<br>
<br>
<br>
2- Run this: "curl<br>
-sÂ<br>
<a href="https://raw.githubusercontent.com/tmartinx/openstack-guides/master/Juno/controller/etc/apt/sources.list.d/ubuntu-cloud-archive-juno-trusty.list%C3%82" target="_blank">https://raw.githubusercontent.com/tmartinx/openstack-guides/master/Juno/controller/etc/apt/sources.list.d/ubuntu-cloud-archive-juno-trusty.listÂ</a><br>
<span>><br>
/etc/apt/sources.list.d/ubuntu-cloud-archive-juno-trusty.list"<br>
<br>
<br>
3- Then: "apt-get install<br>
</span>ubuntu-cloud-keyring python-software-properties ; apt-get update";<br>
<span><br>
<br>
4- Upgrade to Juno with: "apt-get dist-upgrade";<br>
<br>
</span>Â During the upgrade procedure, `dpkg` will ask you to replace some<br>
<span>configuration files, you'll need to chose to keep the files untouched<br>
(n), or to upgrade to the latest version (y).<br>
<br>
</span>Â I prefer to keep with my `nova.conf` (and with my `ml2_conf.ini`),<br>
<span>since it is very customized. Right after the upgrade, I updated<br>
`nova.conf` file according to `<a href="http://doc.openstack.org/juno" target="_blank">doc.openstack.org/juno`</a><br>
</span><<a href="http://doc.openstack.org/juno" target="_blank">http://doc.openstack.org/juno`</a>>.<br>
<br>
 Upgrade the following files: neutron.conf, keystone.conf,<br>
<span>glance-registry.conf, glance-api.conf, glance-scrubber.conf,<br>
/etc/openstack-dashboard/local_settings.py, heat.conf...<br>
<br>
</span>Â Also, keep your ml2_conf.ini (update it later by comparing<br>
<span>`ml2_conf.ini.dpkg-dist`).<br>
<br>
<br>
5- Repeat step 1, stop all services again (their confs are wrong /<br>
empty / from factory);<br>
<br>
<br>
6- Manually compare and update all the configuration files that was<br>
upgraded by `dpkg` on step 4, like this:<br>
<br>
</span>Â cd /etc/keystone<br>
 diff -Nru keystone.conf.dpkg-old keystone.conf | vim -<br>
<br>
 Where "keystone.conf.dpkg-old" is your previous "keystone.conf".<br>
<span>Lines starting with "minus -", was removed by new "keystone.conf",<br>
lines starting with "plus +" was added by it. So, you might want to<br>
restore mostly of your customized settings. Like for example:<br>
<br>
</span>Â admin_token<br>
 bind_host = ::<br>
 connection # [database]<br>
<br>
 Save new "keystone.conf" with your custom settings from<br>
"keystone.conf.dpkg-old"...<br>
<br>
 Run:<br>
<br>
 "rm /var/lib/keystone/keystone.db"<br>
 "su -s /bin/sh -c "keystone-manage db_sync" keystone";<br>
 "service keystone restart"<br>
 "keystone tenant-list"<br>
<span><br>
<br>
7- Repeat step 6 for each configuration file... Remember to run<br>
</span>`diff -Nru ... ...` to compare each new config file with its<br>
<span>`backup.conf.dpkg-old` and before running "db_sync" to starting the<br>
services again (for each service you might have), plus a reboot in the<br>
end to make sure everything is working as expected. Pay attention to<br>
your `ml2_conf.ini`, you'll want to enable `ipset`, compare yours with<br>
`ml2_conf.ini.dpkg-dist`. Review your Cinder confs!<br>
<br>
<br>
8- Enjoy OpenStack Juno!<br>
<br>
<br>
Note: When updating Neutron Server, you'll need to run:<br>
<br>
</span>Â neutron-db-manage --config-file<br>
/etc/neutron/neutron.conf --config-file<br>
/etc/neutron/plugins/ml2/ml2_conf.ini stamp icehouse<br>
<br>
 ...Before:<br>
<br>
 su -s /bin/sh -c "neutron-db-manage<br>
--config-file /etc/neutron/neutron.conf<br>
--config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade juno" neutron<br>
<span>-----<br>
<br>
<br>
Sorry if this is not a complete upgrade procedure but, let me know if<br>
something goes wrong...<br>
<br>
</span>Keep two eyes on `<a href="http://doc.openstack.org/juno" target="_blank">doc.openstack.org/juno`</a> <<a href="http://doc.openstack.org/juno" target="_blank">http://doc.openstack.org/juno`</a>>!<br>
<span><br>
First hand: I'm updating my Juno guide,<br>
</span>here:Â <a href="https://github.com/tmartinx/openstack-guides/tree/master/Juno" target="_blank">https://github.com/tmartinx/openstack-guides/tree/master/Juno</a> -<br>
I'll announce it later, when finished...   :-)<br>
<span><br>
Best!<br>
