Forcentos, use Http://repos.fedorapeople.org/repos/openstack/openstack-grizzly/epel-openstack-grizzly.repo.

Configure the network:

Set up old Ethernet NIC device names:

Sed-i ' s/goto= ' netdevicename_end '/goto= ' netdevicename_end '/g '/lib/udev/rules.d/71-biosdevname.rules

Disable NetworkManager and enable the network service

· Service NetworkManager Stop

· Service Network start

· Chkconfig NetworkManager off

Chkconfig Network on

Edit/etc/sysconfig/network-scripts/ifcfg-eth0:

· Internal Network

· Device=eth0

· Type=ethernet

· Bootproto=static

· ipaddr=10.10.10.10

· netmask=255.255.255.0

· Defroute=yes

· Onboot=yes

Edit/etc/sysconf/network-scripts/ifcfg-eth1:

· 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

Reboot

Edit the/etc/hosts file and add cloud, network, and C01 hostnames with correct IP.

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. Acceptable for a simple or testing environment, it are highly recommended to use Proper DNS entries, or at a minimum a configuration management system such as Puppet, to maintain your IP to host mappings .

Install NTP. NTP would ensure that the server has the correct time. This is important because if a OpenStack server ' s. Not correct, it'll be removed from the rest of the cloud.

· Yum Install-y NTP

MySQL Database Service

The Variousopenstack Components store persistent data in a relational database. MySQL isthe most popular choice.

Install the Packages:

Yum install MySQL mysql-server mysql-python

By default, MySQL'll only accept connections from localhost. This needs changed the compute nodes can access the OpenStack networking service. The Database requests for the OpenStack Compute 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 OpenStack services require need created. Additionally, MySQL accounts to access those databases need created, too:

5. Mysql-u Root-p <<eof

7.GRANT all privileges on nova.* to ' nova ' @ ' localhost ' \
