在每个target host上执行以下操作:
- Naming target hosts.
- Install the operating system.
- Generate and set up security measures.
- Update the operating system and install additional software packages.
- Create LVM volume groups.
- Configure networking devices.
Deployment host到taget host无密码登陆：
Copy Deployment hos的public key到taget /root/.ssh/authorized_keys ssh-copy-id -i ~/.ssh/id_rsa.pub root@192.168.2.22
Configuring the operating system
kernel版本为3.13.0-34-generic or later
$ uname -a Linux rpc-3 3.13.0-46-generic #79-Ubuntu SMP Tue Mar 10 20:06:50 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
# apt-get install bridge-utils debootstrap ifenslave ifenslave-2.6 lsof lvm2 ntp ntpdate openssh-server sudo tcpdump vlan
加入kernel 模块到/etc/modules来enable VLAN和接口bond
# echo 'bonding' >> /etc/modules # echo '8021q' >> /etc/modules
Configure NTP
Reboot the host to activate the changes
Configuring LVM
Cinder节点上要一个cinder-volumes VG，metadata size必须是 2048
pvcreate --metadatasize 2048 /dev/vdb vgcreate cinder-volumes /dev/vdb
Configuring the network
target hosts上的网络必须手动配置因为它们随环境不同而变化很大。
target hosts contains the following components:
可以配置bond：
Bond1 (eth0/2) static IP address 作为管理网络
Bond2 (eth1/3) without an IP address
Bond0 interface and br-mgmt bridge with a static IP address.
bond1 interface and br-vxlan bridge with a static IP address.
VLAN br-vlan bridge on the bond1 interface without an IP
the bond0 interface and br-storage bridge with a static IP address.

配置taget上的 /etc/network/interfaces文件如下：

注意：bond0的IP每个taget都应该不同
service networking restart
之后验证网络配置：
