Welcome to the OpenStack wiki!

In this guide We will install OpenStack Neuton (RDO release) on 4 nodes (control, network, 2 computes) and in additional 2 Ceph's nodes for OpenStack storage (images, volumes, nova), also we will use VXLAN as a default for internal communications.

Environment overview:

  • Control node public IP (eth0): 99.222.111.30
  • Network node (Neutron) public IP (eth0): 99.222.111.31
  • Compute01 node public IP (may consider management network)(eth0): 99.222.111.32
  • Compute01 node public IP (may consider management network)(eth0): 99.222.111.33
  • Ceph node osd01 public IP (eth0): 99.222.111.34
  • Ceph node osd02 public IP (eth0): 99.222.111.35
  • Private network named eth0.100 will explain later.
  • Centos 7.3

Note: we use only one NIC lan port with vlan configuration to support as much as require.

  • For more details on network configuration check the repository at OpenStack Network.
  • For ceph installation check this article ceph 1.3 OR ceph 2, and for ceph integration with OpenStack please look at my repository at Ceph&OpenStack

Openstack installations

Before you start installation of OpenStack prerequisites must done on all nodes (OpenStack):

# systemctl disable firewalld

# systemctl stop firewalld

# systemctl stop NetworkManager

# systemctl disable NetworkManager

# yum update -y

# reboot

# yum install -y centos-release-openstack-neuton

  • On controller node install openstack-packstack and generate answer file for that.

# yum install -y openstack-packstack

# packstack --gen-answer-file answer.txt

  • Generate ssh keys and copy them to all nodes (OpenStack)

# ssh-copy-id {control, network,compute01,compute02}

Note: for more information about answer.txt configuration refer to my repository at OpenStack Network.

  • On controller node start packstack command to start installation:

# packstack --answer-file answer.txt

Welcome to the Packstack setup utility

The installation log file is available at: /var/tmp/packstack/20170425-104230-Zp3fWe/openstack-setup.log

**** Installation completed successfully ******

Additional information: * File /root/keystonerc_admin has been created on OpenStack client host 99.222.111.30. To use the command line tools you need to source the file.

* To access the OpenStack Dashboard browse to https://99.222.111.30/dashboard .

Please, find your login credentials stored in the keystonerc_admin in your home directory.

* The installation log file is available at: /var/tmp/packstack/20170425-104230-Zp3fWe/openstack-setup.log

* The generated manifests are available at: /var/tmp/packstack/20170425-104230-Zp3fWe/manifests

  • Final step is to create br-ex on network node:
  • Edit ifcfg-eth0 to be like this, DEVICE=eth0

ONBOOT=yes

TYPE=OVSPort

DEVICETYPE=ovs

OVS_BRIDGE=br-ex

  • Create ifcfg-br-ex file,

TYPE=OVSBridge

DEVICETYPE=ovs

BOOTPROTO=none

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=no

NAME=br-ex

UUID=d48c3d8d-eed8-4af6-9168-7a18bdf57df6

DEVICE=br-ex

ONBOOT=yes

IPADDR=99.222.111.31

PREFIX=26

GATEWAY=99.222.111.254

DNS1=8.8.8.8

NM_CONTROLLED=no

And then

# systemctl restart network
