Ubuntu12.10 Openstack 安装计算节点(多节点)

设置网络

root@computer-1:~# vim /etc/network/interfaces 
auto lo
iface lo inet loopback

auto br100
iface br100 inet static
      address 10.1.200.172
      netmask 255.255.255.0
      gateway 10.1.200.254
      dns-nameservers 10.1.1.2

bridge_ports em1
bridge_hello 2
bridge_maxage 12
bridge_fd 0
bridge_stp off 

安装网桥软件

Openstack的网络是通过linux的bridge和iptables来实现的。

root@computer-1:~#apt-get -y install bridge-utils

重启网卡生效

安装ISCSI客户端

root@computer-1#apt-get install -y open-iscsi open-iscsi-utils

设置环境变量

推荐加入/root/.bashrc

root@computer-1:~# cat keystone.env.sh 
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=password
export SERVICE_PASSWORD=password
export FIXED_RANGE=10.1.200.0/24
export OS_AUTH_URL="http://10.1.200.174:5000/v2.0/"
export SERVICE_ENDPOINT="http://10.1.200.174:35357/v2.0"
export SERVICE_TOKEN=my_cloud
export MASTER="10.1.200.174"
export OS_NO_CACHE=1

设置NTP

root@computer-1:~#apt-get -y install ntp

编辑 /etc/ntp.conf, 指向控制节点的ntp服务器

#server ntp.ubuntu.com
server 10.1.200.174

重启NTP服务

root@computer-1:~#/etc/init.d/ntp restart

安装计算节点相关软件

为了实现网络的高可用，每个计算节点，都会安装nova-network。并且每个计算节点都需要安装nova-api。

root@computer-1:~#apt-get install -y nova-api nova-common nova-compute nova-compute-kvm  nova-network python-nova python-novaclient python-keystone python-keystoneclient

 编辑 /etc/nova/api-paste.ini , 修改末尾3行

#admin_user = %SERVICE_USER%
#admin_password = %SERVICE_PASSWORD%
#signing_dirname = /tmp/keystone-signing-nova
admin_user = service
admin_password = nova
signing_dirname = password

编辑/etc/nova/nova.conf 文件，这个文件和控制节点区别不大，只需要更改vnc的地方.

root@computer-1:~# vim /etc/nova/nova.conf

重启相关服务

root@computer-1:~#service libvirt-bin restart && service nova-network restart && service nova-compute restart && service nova-api restart

查看服务是是否正常

root@computer-1:~# nova-manage service list

计算节点安装完毕，这时可以在dashboard中创建虚拟机
