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
OpenStack Linux
