This is an example of installing OpenStack using Packstack on local machine so OpenStack VMs are reachable from my LAN (homelab purposes)
Part of instructions are from RDO Project
- capable piece of hardware (citing RDO Project: Machine with at least 16GB RAM, processors with hardware virtualization extensions, and at least one network adapter.)
- up-to-date CentOS 7 Minimal install
- Specific network setup described below (you can adjust installation to your LAN by modifying the installation scripts)
- my physical LAN is 192.168.192.0/23, so:
- 192.168.192.1 - first IP address in LAN (192.168.192.0/24 range is for physical hardware)
- 192.168.193.254 - last IP address in LAN (192.168.193.0/24 range will be for VMs)
- my physical router LAN IP is: 192.168.192.254 and acts as a gateway to the Internet and DHCP server
- DHCP on my physical router assigns IPs from range 192.168.192.100 - 192.168.192.200
- HP Z600 has single NIC with static IP address: 192.168.192.250
- in my case, the Z600 itself is configured to use DHCP
- but my router has a MAC-to-IP binding, so effectively Z600 always gets same IP
- OpenStack is fine with that :)
- ssh to your machine
- make sure you're root
yum install gitgit clone https://github.com/emkor/openstack-on-hp-z600.gitcd openstack-on-hp-z600chmod u+x ./*.sh- execute
./pre_install.shto:- disable SELinux
- replace NetworkManager with network service
- disable firewalld
- install basic OS dependencies and tools (nano, vim, htop etc)
rebootthe machine now, ssh to it again, enter the code dir withcd openstack-on-hp-z600- execute
./install.shto:- install OpenStack Stein using Packstack and answers/config file:
packstack-answers.txtwith basic services:- Keystone for user authentication
- Neutron for networking
- Nova for VM instances
- Glance for VM images
- Cinder for Volumes
- Swift for Object Storage
- Horizon for Web Admin panel
- Heat for orchestration
- be patient, as it may take up to hour
- first login: you can access just-installed OpenStack with
adminuser andszamanszamanpassword - there's not much to see now, though
- install OpenStack Stein using Packstack and answers/config file:
- execute
./post_install.shto:- create
developmentproject with userguestand passwordguest - creates network in such a way that you'll be able to
sshinto instances from your home LAN - creates basic Keypair (basically SSH key) for user
guestso you're able to ssh into instances using public keyguest.pem(under~/.ssh) - creates basic Security Group (basically firewall) with all traffic allowed (ICMP+UDP+TCP ingress+egress)
- re-arranges Instance Flavors (basically pre-defined Instance sizes) so they fit host resources
- create
- optionally, do
image/create_base_images.sh- downloads and creates images for Centos 7, CoreOS, Debian 9 and Ubuntu 18.04 LTS and Ubuntu 19.04
- optionally, create basic images with specific SDKs (Python, Java, Docker etc.) for Ubuntu 18.04 LTS using dirs under
image/
- OpenStack instance installed at 192.168.192.250 (SSH-able as root and HTTP-able as either
adminorguest) - OpenStack will have following services: Keystone, Neutron, Nova, Glance, Cinder, Horizon, Heat
- OpenStack uses 192.168.193.1-192.168.193.254 address range as Floating IPs; those are "public IPs" for VMs, reachable from your LAN
- OpenStack uses 172.16.0.0/16 network range as its internal network; those IPs are not reachable from your LAN
