Introduction

The Controllernode will provide:

MySQL DatabaseService

Qpid MessagingService

Operating System

Install Fedora 18. The exact installation procedure is outsidethe scope of this document, but please note the followingations:

Once installation has finished, the server will reboot.

UseFedoraRepositories for Grizzly:

3. wgethttp: // repos.fedorapeople.org/repos/openstack/openstack-grizzly/fedora-openstack-grizzly.repo

Mv fedora-openstack-grizzly.repo/etc/yum. repos. d/

	Note
	ForCentOS, Usehttp: // repos.fedorapeople.org/repos/openstack/openstack-grizzly/epel-openstack-grizzly.repo.

Configure the network:

Sed-I's/GOTO = "netdevicename_end"/GOTO = "netdevicename_end"/g'/lib/udev/rules. d/71-biosdevname.rules

Service NetworkManager stop

Service network start

Chkconfig NetworkManager off

Chkconfig network on

Internal Network

DEVICE = eth0

TYPE = Ethernet

BOOTPROTO = static

IPADDR = 10.10.10.10

NETMASK = 255.255.255.0

DEFROUTE = yes

ONBOOT = yes

External Network

DEVICE = eth1

TYPE = Ethernet

BOOTPROTO = static

IPADDR = 10.0.0.10

NETMASK = 255.255.255.0

GATEWAY = 10.0.0.1

DNS = 8.8.8.8

DEFROUTE = yes

ONBOOT = yes

127.0.0.1 localhost

10.10.10.10 cloud

10.10.10.9 network

10.10.10.11 c01

	Note
	While manually specifying host entries is acceptable for asimple or testing environment, it is highly recommended to useproper DNS entries, or at a minimum a configuration managementsystem such as Puppet, to maintain your IP to host mappings.

Install NTP. NTP will ensure that the server has the correcttime. This is important because if an OpenStack server's time isnot correct, it will be removed from the rest of the cloud.

Yum install-y ntp

MySQL Database Service

The variousOpenStack components store persistent data in arelational database. MySQL isthe most popular choice.

Install the packages:

Yum installMysql Mysql-Server MySQL-python

By default, MySQL will only accept connections from localhost. This needs changed so that the compute nodes can access theOpenStack Networking service. Database requests for the OpenStackCompute service are proxied through the nova-conductor service.

Sed-I's/127.0.0.1/0.0.0.0/g'/etc/my. cnf

Restart the service:

Systemctl start mysqld. service

Service mysqld restart

Chkconfig mysqld on

The various databases that the OpenStack services require needcreated. Additionally, MySQL accounts to access those databasesneed created, too:

5. mysql-u root-p <

6. create database nova;

7. grant all privileges on nova. * TO 'Nova '@ 'localhost '\

8. identified by 'password ';

9. create database cinder;

10. grant all privileges on cinder. * TO 'cinder' @ 'localhost '\

11. identified by 'password ';

12. create database glance;

13. grant all privileges on glance. * TO 'glance '@ 'localhost '\

14. identified by 'password ';

15. create database keystone;

16. grant all privileges on keystone. * TO 'Keystone '@ 'localhost '\

17. identified by 'password ';

18. create database quantum;

19. grant all privileges on quantum. * TO 'Quantum '@ 'localhost '\

20. identified by 'password ';

21. grant all privileges on quantum. * TO 'Quantum '@ '10. 10.10.9 '\

22. identified by 'password ';

23. grant all privileges on quantum. * TO 'Quantum '@ '10. 10.10.11 '\

24. identified by 'password ';

25. flush privileges;

Qpid Messaging Service

The OpenStackcomponents also communicate through a queuingservice. for example, the CloudController places a request tolaunch an instance on the queue. the ComputeNode then picks thisrequest up and launches the instance. openStack can workwithseveral different queuing services.

Install the packages:

Yum install qpid-cpp-server

Enable authentication:

Echo auth = 1>/etc/qpidd. conf

Change yes in/etc/qpidd. conf to no.

Enable the messaging service:

Chkconfig qpidd on

# Saslpasswd2-f/var/lib/qpidd. sasldb-u QPID guest
> Password: guest
> Again (for verification): guest

... Wait for a moment while it updates...

... And then to validate that these usersactually exist now:
[Root @ OS-controller ~] # Sasldblistusers2-f/var/lib/qpidd. sasldb
Guest @ QPID: userPassword <--- password obscured by program
Steve @ QPID: userPassword <-- another I added "just to test"

There were no users listed in the SASLdbat all after my initialinstallation, so the QPID docs (security chapter) werequitehandy:

Start the messaging service:

Service qpidd start

OpenStack Identity Service

The OpenStackIdentity Service provides the cloud environmentwith an authentication andauthorization system. In this system, users are a part of one or more projects. In each of these projects, they hold a specific role.

Install the packages:

Yum install openstack-utils openstack-keystonepython-keystoneclient

Edit/Etc/keystone. conf:

3. [DEFAULT]

4. admin_token = password

5. debug = True

6. verbose = True

7.

8. [SQL]

Connection = mysql: // keystone: password @ localhost/keystone

Create the ssl keys:

10. keystone-manage pki_setup

Chown-R keystone: keystone/etc/keystone /*

Restart Keystone and create the tables in the database:

12. service openstack-keystone restart

Openstack-d
