OpenStack: Install with Packstack

Install Packstack

[root@server2-a ~]# yum install -y openstack-packstack

Create an answers file for automated installation

[root@server2-a ~]# packstack --gen-answer-file /root/answers.txt

Edit the answers file with a few settings:

CONFIG_NTP_SERVERS=pool.ntp.org
CONFIG_KEYSTONE_ADMIN_PW=redhat
CONFIG_HORIZON_SSL=y
CONFIG_PROVISION_DEMO=n

Run Packstack using answers file

[root@server2-a ~]# packstack --answer-file /root/answers.txt

 * File /root/keystonerc_admin has been created on OpenStack client host 172.25.2.10. To use the command line tools you need to source the file.
 * NOTE : A certificate was generated to be used for ssl, You should change the ssl certificate configured in /etc/httpd/conf.d/ssl.conf on 172.25.2.10 to use a CA signed cert.
 * To access the OpenStack Dashboard browse to https://172.25.2.10/dashboard .
Please, find your login credentials stored in the keystonerc_admin in your home directory.
 * To use Nagios, browse to http://172.25.2.10/nagios username: nagiosadmin, password: 135225bb92224f28
 * Because of the kernel update the host 172.25.2.10 requires reboot.

Warning keystonerc not sourced

Amend local networking configuration (attach eth0 to Open Vswitch external bridge for 2 interface systems)

NB: OpenStack guidelines suggest systems should have 3 interfaces: Management, External & Interconnect
The External interface is accessed via a bridge - br-ex
If the system has only 2 interfaces, the Management interface can share the same bridge.

• Copy network config files

[root@server2-a ~]# cp /etc/sysconfig/network-scripts/ifcfg-eth0 /root/
[root@server2-a ~]# cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-br-ex

• Edit eth0 config file:

DEVICE=eth0
ONBOOT=yes
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=br-ex

• Edit the new br-ex config file:

DEVICE=br-ex
BOOTPROTO=static
ONBOOT=yes
TYPE=OVSBridge
DEVICETYPE=ovs
USERCTL=yes
PEERDNS=yes
IPV6INIT=no
IPADDR=172.25.2.10
NETMASK=255.255.255.0
GATEWAY=172.25.2.254
DNS1=172.25.254.254

• Add eth0 to br-ex bridge and set hostname:

[root@server2-a ~]# ovs-vsctl add-port br-ex eth0 ; systemctl restart network.service 
[root@server2-a ~]# hostnamectl set-hostname server2-a.example.com

NB: ovs-vsctl add-port br-ex eth0 is apparently not vital

• Set hostname:

[root@server2-a ~]# hostnamectl set-hostname server2-a.example.com

NB: This assigns a static hostname rather than that transient hostname.
