Packstack –answer-file方式部署多节点openstack环境--三节点
5.1 Centos环境准备
| Hostname |
IP |
flating ip |

|
| Lxp-node1 |
192.168.11.10 |
10.33.41.135
|
Controller+network |
|
| Lxp-node2 |
192.168.11.11 |
10.33.41.136
|
Compute+storage |
|
| Lxp-node3 |
192.168.11.12 |
10.33.41.139
|
Compute+storage |
|
/etc/hostname都要改
/etc/hosts增加：
192.168.11.10 lxp-node1
192.168.11.11 lxp-node2
192.168.11.12 lxp-node3
10.1.14.235 mirrors.hikvision.com.cn
将网卡配置成开机启动:
/etc/sysconfig/network-scripts/ifcfg-eth0中，将ONBOOT=no改为yes
配置yum 源，配置为公司内部的yum源，安装会很快
5.2 使用packstack部署三节点openstack环境
在三个节点安装packstack：
yum install openstack-packstack -y
生成answer-file：
# packstack --gen-answer-file=hcloud.txt
修改hcloud.txt中的如下配置：
（1）修改计算节点和网络节点IP
[root@lxp-node1 ~]# grep HOST ./hcloud.txt
CONFIG_CONTROLLER_HOST=192.168.11.10
CONFIG_COMPUTE_HOSTS=192.168.11.10 改为：CONFIG_COMPUTE_HOSTS=192.168.11.11,192.168.11.12
CONFIG_NETWORK_HOSTS=192.168.11.10
CONFIG_VCENTER_HOST=
CONFIG_STORAGE_HOST=192.168.11.10改为：CONFIG_STORAGE_HOST=192.168.11.11,192.168.11.12
CONFIG_SAHARA_HOST=192.168.11.10
CONFIG_AMQP_HOST=192.168.11.10
CONFIG_MARIADB_HOST=192.168.11.10
（2）不安装cirros镜像
另外将CONFIG_PROVISION_DEMO=y改为n
部署之前再检查一下/etc/hostname和/etc/hosts:
节点1：
[root@lxp-node1 ~]# cat /etc/hostname
lxp-node1
[root@lxp-node1 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.11.10 lxp-node1
192.168.11.11 lxp-node2
192.168.11.12 lxp-node3
10.1.14.235 mirrors.hikvision.com.cn
节点2：
[root@lxp-node2 ~]# cat /etc/hostname
lxp-node2
[root@lxp-node2 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.11.10 lxp-node1
192.168.11.11 lxp-node2
192.168.11.12 lxp-node3
10.1.14.235 mirrors.hikvision.com.cn
节点3：
[root@lxp-node3 ~]# cat /etc/hostname
lxp-node3
[root@lxp-node3 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.11.10 lxp-node1
192.168.11.11 lxp-node2
192.168.11.12 lxp-node3
10.1.14.235 mirrors.hikvision.com.cn
再次检查hcloud.txt：
[root@lxp-node1 ~]# grep HOST ./hcloud.txt
CONFIG_CONTROLLER_HOST=192.168.11.10
CONFIG_COMPUTE_HOSTS=192.168.11.11,192.168.11.12
CONFIG_NETWORK_HOSTS=192.168.11.10
CONFIG_VCENTER_HOST=
CONFIG_STORAGE_HOST=192.168.11.11,192.168.11.12
CONFIG_SAHARA_HOST=192.168.11.10
还有如下选项：
[root@lxp-node1 ~]# grep CONFIG_PROVISION_DEMO ./hcloud.txt
CONFIG_PROVISION_DEMO=n
开始部署，只在控制节点执行即可：
# yum install screen
# screen packstack--answer-file=hcloud.txt
Welcome to the Packstack setup utility
The installation log file is available at:/var/tmp/packstack/20160509-021808-zfHLVi/openstack-setup.log

这里需要手动输入三台节点的密码，接下来一直等待直到部署完成：

部署成功后，出现如下信息：

这里cinder-volume还是安装到了lxp-node1，即控制节点上
这里可能是packstack的bug，不过关系不大，cinder-volume大不了手动部署一下
接下来尝试下四个节点的安装
