OpenStack RDO部署vlan模式
controll:eth0 192.168.2.211 comput:etho 192.168.2.212eth1 eth1
1、网络设置
controll
eth0:
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
HWADDR=00:E0:81:D8:43:BE
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.2.211
NETMASK=255.255.255.0
GATEWAY=192.168.2.1
DNS1=8.8.8.8
View Code eth1:
# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1

ONBOOT=yes

进入到 /etc/yum.repos.d, 其中有个rhel-source.repo, 先改名为rhel-source.repo.bak,做个备份
然后新建个 rhel-source.repo
cd /etc/yum.repos.d
mv rhel-source.reop rhel-source.reop.bak
vi rhel-source.reop
内容如下:
name=CentOS-$releasever - Base
baseurl=http://mirrors.163.com/centos/6.5/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
#released updates
name=CentOS-$releasever - Updates
baseurl=http://mirrors.163.com/centos/6.5/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
#packages used/produced in the build but not released
#
#name=CentOS-$releasever - Addons
#baseurl=http://mirrors.163.com/centos/6.5/addons/$basearch/
#gpgcheck=1
#gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
#additional packages that may be useful

#additional packages that extend functionality of existing packages
name=CentOS-$releasever - Plus

gpgcheck=1
enabled=0

yum update
3、交换机设置
需要把两台机器的eth1,设置成trunk.
虚拟机的通讯，是通过eth1，虚拟机访问外部网络，是通过node10上的L3agent，br-ex到eth0上访问外部网络。
交换机把虚拟机通讯的端口设置trunk模式，vlan的id是从1000到2000.
4、开始安装
安装packstack
yum install -y http://rdo.fedorapeople.org/openstack/openstack-havana/rdo-release-havana.rpm
yum install -y openstack-packstack
创建一个应答文件
packstack --gen-answer-file=multi-node.txt
修改应答文件，由于我已经有专门的cinder volume, 所以不需要创建。如果你没有手工创建cinder volume，那么你就不修改就可以。
CONFIG_CINDER_VOLUMES_CREATE=n
CONFIG_HEAT_INSTALL=y
CONFIG_NTP_SERVERS=0.uk.pool.ntp.org
CONFIG_NAGIOS_INSTALL=y
CONFIG_KEYSTONE_ADMIN_PW=admin (登入密码)
CONFIG_NOVA_COMPUTE_HOSTS=192.168.2.211,192.168.2.212 （控制，计算节点的IP）
CONFIG_NEUTRON_OVS_TENANT_NETWORK_TYPE=vlan （vlan模式）
CONFIG_NEUTRON_OVS_VLAN_RANGES=physnet1:1000:2000 （虚拟机池）
CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-eth1
CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-eth1:eth1
CONFIG_HEAT_CLOUDWATCH_INSTALL=y
CONFIG_HEAT_CFN_INSTALL=y
CONFIG_NAGIOS_PW=nagios
开始安装
packstack --answer-file=multi-node.txt
安装过程，有可能因为源的原因中断，你可以重复运行。
如果遇到网络问题可以看下/etc/resolv.conf
vi /etc/resolv.conf
5、完善
装完后，由于目前RDO的问题，没有创建br-ex，需要我们手工来创建
# cat /etc/sysconfig/network-scripts/ifcfg-br-ex
DEVICE=br-ex
IPADDR=192.168.2.211
PREFIX=24
GATEWAY=192.168.2.1
DNS1=8.8.8.8
ONBOOT=yes
修改 /etc/sysconfig/network-scripts/ifcfg-eth0,注意：一定要加上eth0 的mac地址，不然会出错。
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
HWADDR=00:E0:81:D8:43:BE
然后运行下面命令
ovs-vsctl add-port br-ex eth0; service network restart
当运行 ovs-vsctl add-port的时候，网络就会中断，所以你两条命令需要一起执行。
剩下的操作就是在Dashboard
http://192.168.2.211 登陆Dashboard，密码你可以查看
# cat /root/keystonerc_admin
export OS_USERNAME=admin
export OS_TENANT_NAME=admin
export OS_PASSWORD=admin
export OS_AUTH_URL=http://172.28.1.10:35357/v2.0/
export PS1='[\u@\h \W(keystone_admin)]\$
