Build a multi Node Openstack Environment with Openvswitch

Since I have some time to write again I would like to share a small HowTo, how to Install a multi Node Openstack install with Openvswitch (ovs) and provider Networks as vlans for mixed Environments. At the end I will also add a subsection how to add a second vlan and a script how to add tenants, users and internal Networks for the tenants.

The whole Setup is made with Devstack, some bash-scripts. What you should look at, is for sure multi homing (iproute2) and a general documentation about
openvswitch and HowTo operate Openstack with provider networks. Over all this Documentation should be doable also without this (hopefully) and hopefully I have no typos 😉

Lets assume we have 3 networks / vlans
1. Network is the Management Network (for the communication between the nodes and for the webinterface -> Horizon)
The network is: lets say vlan 29 this must be tagged (access port) on the switch / bladecenter –> as vlan 29 HINT: this is the „Segmentation ID“ the gateway is at the end:

sms gateway under linux

Sitting here, having some USB UMTS Sticks, one Huwaiand one Novatel Wireless, I was thinking to build up an SMS gateway, first of all
for company use, to get Nagios alert SMS, and also to receive an EMail converted to
an SMS on one separate EMail Account.  I’ll use just one of this UMTS Sticks, I guess I have more here
laying around, maybe I will check them later.

Here we go, night is long enough …

Script for adding new Subdomains/trac/git

Script for creating Apache Subdomains, Git Project, Trac Project,
(I put it in gitolite-admin repos and published it to /root/devel_scripting/gitolite-admin/)
Your Apache stores the logfiles afterwards in your subdomain-Webroot, so that you easily
can check the errorlogs while you’re testing your site.
