kvm_scripts

Bash scripts for VMs management

These scripts are used to setup an Openstack infrastructure

This is just an exmaple to show how to add a picture here

0. Big steps:

0.1) Prepare Openstack Servers (Baremetals or VMs)

0.2) Configure network interfaces on each server

0.3) Install Openstack software

1) Prepare Openstack Servers:

Here we use 3 VMs as servers for Openstack Controller + Compute + Network. I put up a script for this here:
git clone https://github.com/thuydang/kvm_scripts my_openstack_dev_dir

1.1) Use create_image.sh to create a VM and setup Fedora 20 on it:

- edit create_image.sh with proper image-name for the VM.
- install Fedora 20 when prompted.

1.2) The installed image will be located in folder images.

copy it to 3 new images: image-name-{controller, compute, network}.qcow2

2) Configure network intefaces on the 3 server as follow:

Network diagram here!

2.1) There are 3 network interfaces on each Server. 3 Sample network files for each server are in: scripts/ifcfg-ensx. Edit them for each server according to the diagram above.

2.2 Configure /etc/hostname and /etc/hosts so the servers can resolve each other.

3) ssh / vnc to each server and install the respective Openstack software:

For each server:

3.1) Disable firewall, selinux, etc..

TBD

3.2) Install puppet

yum install -y puppet

Install puppet modules for Openstack Juno: puppet module install puppetlabs-openstack --version 5.0.2

Replace openstack module with the customized one for our servers: cd /etc/puppet/modules/ rm -rf openstack git clone https://github.com/thuydang/puppetlabs-openstack/tree/td_up_5.0.2 openstack

3.3) Follow this to install Openstack
