现在 ubuntu 上安装已经比较方便，但是 CentOS 下安装 openstack 2012还是比较痛苦，我做了一个软件包，方便大家使用：
http://openstack.pubyun.com/centos/6/pubyun/x86_64/
安装方法如下：
wget -O /etc/yum.repos.d/pubyun.repo http://openstack.pubyun.com/centos/6/pubyun/x86_64/pubyun.repo
安装epel的源：
rpm -i http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-5.noarch.rpm
安装 kvm 虚拟机软件：
yum -y install kvm virt-manager libvirt libvirt-python python-virtinst libvirt-client bridge-utils
安装openstack 和相应的软件：
yum -y install openstack-nova openstack-glance openstack-keystone openstack-dashboard rabbitmq-server python-pip python-tempita ntp ntpdate
#升级 sqlalchemy
pip-python install -U sqlalchemy
启动 mysql server:
chkconfig mysqld on && service mysqld restart
设置和启动 libvritd:
perl -pi -e “s|#mdns_adv|mdns_adv|” /etc/libvirt/libvirtd.conf
perl -pi -e “s|#auth_unix_rw|auth_unix_rw|” /etc/libvirt/libvirtd.conf
chkconfig libvirtd on && service libvirtd restart
virsh net-autostart default –disable
virsh net-destroy default
启动 ntp 时间同步：
chkconfig ntpd on && service ntpd restart
设置用户密码，注意，域名一定要设置正确，否则 rabbitmq-server 无法正常启动。如果不能控制域名服务器:
vi /etc/sysconfig/network
#设置成你要的域名
HOSTNAME=nova.pubyun.com
vi /etc/hosts
#正确配置域名服务器，或者将域名、IP写入 hosts文件
#IP是你当前机器的IP，域名是你刚才设置的域名
172.16.11.12 nova.pubyun.com nova
如果不想重新启动机器，则：
hostname nova.pubyun.com
启动 rabbitmq-server:
chkconfig rabbitmq-server on && service rabbitmq-server restart
rabbitmqctl change_password guest nova
查看rabbitmq-server的状态：
rabbitmqctl list_exchanges
rabbitmqctl list_queues
rabbitmqctl list_bindings
设置 lvm for nova volume:
dd if=/dev/zero of=/var/lib/nova/nova-volumes.img bs=1M seek=20k count=0
vgcreate nova-volumes $(losetup –show -f /var/lib/nova/nova-volumes.img)
设置 nova 的一些参数：
openstack-config-set /etc/nova/nova.conf DEFAULT libvirt_type kvm
openstack-config-set /etc/nova/nova.conf DEFAULT rpc_backend nova.rpc.impl_kombu
openstack-config-set /etc/nova/nova.conf DEFAULT rabbit_host localhost
openstack-config-set /etc/nova/nova.conf DEFAULT rabbit_password nova
openstack-config-set /etc/nova/nova.conf DEFAULT auth_strategy keystone
设置 nova 的数据：
openstack-nova-db-setup
openstack-keystone-db-setup
设置用户名：
cat > keystonerc <<EOF
export ADMIN_TOKEN=$(openssl rand -hex 10)
export OS_USERNAME=admin
export OS_PASSWORD=nova
export OS_TENANT_NAME=admin
export OS_AUTH_URL=http://127.0.0.1:5000/v2.0/
EOF
. ./keystonerc
mkdir -p /var/run/keystone
chown keystone.keystone /var/run/keystone/
#启动 keystone
openstack-config-set /etc/keystone/keystone.conf DEFAULT admin_token $ADMIN_TOKEN
chkconfig openstack-keystone on && service openstack-keystone restart
#导入keystone数据：
ADMIN_PASSWORD=$OS_PASSWORD openstack-keystone-sample-data
#查看一下，keystone是否工作：
keystone user-list
keystone tenant-list
#设置、启动 glance

for svc in api registry; do chkconfig openstack-glance-$svc on; done
for svc in api registry; do service openstack-glance-$svc status; done
grep -i error /var/log/glance/*.log
导入image：
curl http://images.ansolabs.com/tty.tgz | tar -xzv
glance add name=aki-tty is_public=true container_format=aki disk_format=aki < aki-tty/image
glance add name=ari-tty is_public=true container_format=ari disk_format=ari < ari-tty/image
glance add name=ami-tty is_public=true container_format=ami disk_format=ami \
“kernel_id=$(glance index | awk ‘/aki-tty/ {print $1}’)” \
“ramdisk_id=$(glance index | awk ‘/ari-tty/ {print $1}’)” \
< <(zcat –force ami-tty/image)
检查 glance 是否正常工作：
glance index
#启动 nova
sed -i -e ‘s/# \(pipeline = .*\keystone\)/\1/g’ /etc/nova/api-paste.ini
openstack-config-set /etc/nova/api-paste.ini filter:authtoken admin_token $ADMIN_TOKEN
for svc in api cert compute network objectstore scheduler volume; do service openstack-nova-$svc start; done

#nova 是否正常工作
