之前一篇博客介绍了华为发布的针对Icehouse版本的all in one安装镜像,因为OpenStack安装后还需要进行一系列的初始配置(大家的环境和需求各异,因此没有直接集成在自动化中)。对于小白用户来说,可能还不能满足需求,今天我就一步一步教大家入门。

准备和注册镜像、Keypair

拷贝所需的镜像到服务器的任意目录(比如/home/images),我这里有3个镜像

UVP:/home/images # ll
total 683292
-rw-r--r-- 1 root root 476704768 Mar 24 20:33 F17-x86_64-cfntools.qcow2
-rw-r--r-- 1 root root   9159168 Jan 14  2013 cirros-0.3.0-i386-disk.img
-rw-r--r-- 1 root root 213123072 Jan 14  2013 precise-server-cloudimg-i386-disk1.img

注册(注意,在最后一步,我添加了一个密钥并设置了正确的权限):

glance image-create --name="Ubuntu 12.04 cloudimg i386" --public --container-format=ovf --disk-format=qcow2 < /home/images/precise-server-cloudimg-i386-disk1.img
glance image-create --name=cirros --public  --container-format=bare --disk-format=qcow2 < /home/images/cirros-0.3.0-i386-disk.img
glance image-create --name="F17-x86_64-cfntools" --public --container-format=ovf --disk-format=qcow2 < /home/images/F17-x86_64-cfntools.qcow2
nova keypair-add heathey > heatkey.pem
chmod 600 heatkey.pem

创建网络

all in one的安装要求服务器有三个网卡,我的服务器eth0所在的网段是172.25.0.0/16,eth2(默认br-ex连接的网卡,all in one配置下,eth1其实用不到)所连接汇聚交换机端口上配置的网关为200.200.1.1/16,因此给Neutron分配的floatingIP段就比较随意了,我这里是200.200.200.100-120

创建虚拟机并验证VNC登陆

通过VNC登录虚拟机后,查看虚拟机的IP(证明系统的DHCP功能正常):

配置安全组允许PING和SSH登录:

UVP:/home/kong # nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range  | Source Group |
+-------------+-----------+---------+-----------+--------------+
| tcp         | 22        | 22      | 0.0.0.0/0 |              |
+-------------+-----------+---------+-----------+--------------+
UVP:/home/kong # nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range  | Source Group |
+-------------+-----------+---------+-----------+--------------+
| icmp        | -1        | -1      | 0.0.0.0/0 |              |
+-------------+-----------+---------+-----------+--------------+

还记得之前添加的密钥么,现在对虚拟机进行PING和SSH登录操作(10.1.1.4是我的虚拟机的私有IP),功能OK:

UVP:/home/kong # ip netns list
