openstack安装详解

2.1 硬件环境说明

2.2 软件环境说明

查看硬件环境之上的系统版本和内核参数

# rpm -qa centos-release

centos-release-6.6.e16.centos.12.2.x86_64

# uname -a

Linux YUN-11 2.6.32-504.3.3.e16.x86_64 #1SMP Web Dec 17 01:55:02 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

2.3 网络规划和 IP 地址规划

ip：192.168.0.100-192.168.0.106

3 安装前准备

3.1 系统安装说明

说明一：

选择时区“亚洲-上海”

说明二：

分区时选择“Use All Space”

因为 Openstack 云主机磁盘大小对应/ 分区的大小，另外 linux 分区默认情况下/home 分区比较大，而/ 分区太小，要按实际情况把/home分区调小，把/ 分区调大

说明三：

安装模式选择“Minimal”

3.2 主机配置

配置 1：网络配置

按照地址规划，给服务器配置相应的 IP 地址测试主机之间的连通状况

配置 2：hosts 文件配置

以主机 YUN-11 为例

# vi /etc/hosts

添加下面内容

127.0.0.1 YUN-11

其他主机依次做修改

3.3 YUM 源

3.3.1 软件网络源下载并处理

 在一台可以连通网络的 linux 主机上下载网络软件源，因为网络软件源过大，所以这里要求 linux 主机磁盘不能太小（50G 以上就行），网速必须要快，在根目录下下载，因为安装是在 CentOS 发行版下进行，所以首先将 CentOS 的源拿到本地。

# wget -S -c -r -np -L http://mirrors.163.com/centos/6/--accept=rpm,gz,xml

下载 OpenStack-Icehouse 版本的包

# wget -c -r -np --reject=html,gif,A,D -nH http://repos.fedorapeople. org/repos/openstack/openstack-icehouse/epel-6/

下载 puppet 包

# wget -S -c -r -np -L https://yum.puppetlabs.com/el/6/.

下载 epel test 相关包

# wget -S -c -r -np -L http://dl.fedoraproject.org/pub/epel/testing/6/.

下载 epel 包

# wget -S -c -r -np -L http://dl.fedoraproject.org/pub/epel/6/.

下载 foreman 包

# wget -S -c -r -np -L http://yum.theforeman.org/plugins/1.5/el6/

# wget -S -c -r -np -L http://yum.theforeman.org/release/1.5/el6/

过程会持续很长时间

下载完成后需要删除安装过程用不着的软件

# cd /yum.puppetlabs.com/el/6/devel

# rm -rf SRPMS

# rm -rf i386

# cd /dl.fedoraproject.org/pub/epel/testing/6/

# rm -rf SRPMS

# rm -rf i386

# rm -rf ppc64

# cd /dl.fedoraproject.org/pub/epel/6/

# rm -rf SRPMS

# rm -rf i386

# rm -rf ppc64

# cd /yum.theforeman.org/plugins/1.5/el6/

# rm -rf source

# cd /yum.theforeman.org/release/1.5/el6/

# rm -rf source

3.3.2 配置软件源

在四个物理节点上做下列操作

# cd /etc/yum.repos.d

# mv CentOS-Base.repo CentOS-Base.repo.bak

上传 CentOS6-Base-163.repo 、 epel-release-6-8.noarch.rpm 和 rdo-release-icehouse-4.noarch.rpm 到该目录下

# rpm -ivh epel-release-6-8.noarch.rpm

# rpm -ivh rdo-release-icehouse-4.noarch.rpm

编辑目录下面的五个 repo 文件

# mv CentOS6-Base.repo  CentOS-Base.repo

# vi CentOS-Base.repo

内容如下

3.3.3 安装 Apache 并启动服务

转到 YUM 源服务器上

# yum install -y httpd

# service httpd start

# chkconfig httpd on

# rm -f /etc/httpd/conf.d/welcome.conf（删除 web 欢迎页面）

把之前处理完成后的软件拷贝到 YUM 源服务器/var/www/html 目录

然后把/yum.theforeman.org/release 和/yum.theforeman.org/plugins 目

录以及目录下的文件放到/yum.theforeman.org 目录下

4 开始部署 openstack

4.1 部署控制节点

4.1.1 安装 openstack-packstack

# yum install -y openstack-packstack

# yum update

# reboot

4.1.2 部署

# packstack --allinone --provision-all-in-one-ovs-bridge=n --provision-d emo=n

4.1.3 网桥配置

# vi /etc/syscofnfig/network-scripts/ifcfg-eth2

内容如下

DEVICE=eth2

HWADDR=xx:xx:xx:xx:xx:xx

TYPE=OVSPort

OVS_BRIDGE=br-ex

DEVICETYPE=ovs

ONBOOT=yes

# vi /etc/syscofnfig/network-scripts/ifcfg-br-ex

内容如下

DEVICE=br-ex

DEVICETYPE=ovs

TYPE=OVSBridge

BOOTPROTO=static

IPADDR=192.168.0.101

NETMASK=255.255.255.0

GATEWAY=10.231.29.1

ONBOOT=yes

# vi/etc/syscofnfig/network-scripts/ifcfg-eth1 BOOTPROTO=dhcp

to BOOTPROTO=none

添加

IPADDR=10.0.0.11

NETMASK=255.255.255.0

# vi /etc/neutron/plugin.ini

network_vlan_ranges = physnet1（修改）

bridge_mappings = physnet1:br-ex（添加）

这里需要注意的是添加的内容要靠着左边，不能有空格

# ovs-vsctl add-port br-ex eth2

（使用不间断重启网络）

4.2 部署扩展节点

4.2.1 配置

控制节点上

# cd /root

# vi packstack-answer-xxxx.txt (xxxx 为时间日期序号) CONFIG_NOVA_COMPUTE_PRIVIF=lo

to

CONFIG_NOVA_COMPUTE_PRIVIF=eth2

CONFIG_NOVA_NETWORK_PRIVIF=lo

to

CONFIG_NOVA_NETWORK_PRIVIF=eth2

CONFIG_COMPUTE_HOSTS=192.168.0.101

to

CONFIG_COMPUTE_HOSTS=192.168.0.102，192.168.0.103，192.168.0.104

(这里需要注意的是把 lo 改为 eth2 网卡并不一定使用与其他物理环境，

这里指实际应用的第二块网卡，在实际部署时要视情况而定)

4.2.2 部署

packstack --answer-file= packstack-answer-xxxx.txt
