# Configure Openstack to Boot Baremetal nodes Using Devstack
|
|
|
|
## Download and install OpenStack using DevStack
|
|
- git clone https://github.com/openstack-dev/devstack.git devstack
|
|
- sudo ./devstack/tools/create-stack-user.sh
|
|
- sudo su stack
|
|
- cd ~
|
|
- git clone https://github.com/openstack-dev/devstack.git devstack
|
|
- cd Devstack
|
|
- in Devstack, Create local.conf :
|
|
```python
|
|
|
|
[[local|localrc]]
|
|
#Enable Ironic API and Ironic Conductor
|
|
enable_service ironic
|
|
enable_service ir-api
|
|
enable_service ir-cond
|
|
#Enable Neutron which is required by Ironic and disable nova-network.
|
|
disable_service n-net
|
|
disable_service n-novnc
|
|
enable_service q-dhcp
|
|
enable_service q-svc
|
|
enable_service q-agt
|
|
enable_service q-l3
|
|
enable_service q-meta
|
|
enable_service neutron
|
|
#Optional, to enable tempest configuration as part of devstack
|
|
disable_service tempest
|
|
disable_service heat h-api h-api-cfn h-api-cw h-eng
|

|
|
- Configure network Interface (assuming port eth2 is used to connect openstack to rackHD)
|
|
|
|
|
|
|
|
- cat>>/etc/network/interfaces
|
|
```python
|
|
|
|
auto eth2
|
|
iface eth2 inet static
|
|
address 172.31.128.7
|
|
netmask 255.255.255.0
|
|
```
|
|
- Restart network service
|
|
- sudo ifdown eth2
|
|
- sudo ifup eth2
|
|
- Run ./stack.sh
|
|
|
|
## Configure Neutron
|
|
|
|
Once the installation is completed, an external bridge can be setup for Neutron physical network
|
|
|
|
- Bind eth2 to the external bridge:
|
|
- ovs-vsctl add-port br-eth2 eth2
|
|
- Enable external network access under nested Open vSwitch
|
|
- ifconfig br-eth2 promisc up
|
|
- Update external bridge configuration cat>>/etc/network/interfaces
|
|
```python
|
|
|
|
auto eth2
|
|
iface eth2 inet manual
|
|
auto br-eth2
|
|
iface br-eth2 inet static
|
|
address 172.31.128.7
|
|
netmask 255.255.255.0
|
|
```
|
|
- Restart network service
|
|
- sudo ifdown br-eth2
|
|
- sudo ifup br-eth2
|
|
|
|
- Create Flat netwok:
|
|
- Source ~/devstack/openrc admin admin
|
|
- neutron net-create flat-provider-network --shared --provider:network_type flat -- provider:physical_network physnet1
|
|
- neutron subnet-create --name flat-provider-subnet --gateway 172.31.128.7 --dns-nameserver 172.31.128.254 --allocation-pool start=172.31.128.100,end=172.31.128.150 flat-provider-network 172.31.128.0/24
|
|
|
|
## Spawn an instance using nova service
|
|
- Login the horizon interface (user:admin,password:root)
|
|
- Use horizon to create new instances
|
