Openstack

一、准备环境

1、配置两台虚拟机

vh01.tedu.cn 192.168.4.1/24   DNS服务器 NTP服务器

vh02.tedu.cn 192.168.4.2/24 192.168.2.2/24 OPENSTACK服务器

DNS指向192.168.4.1 内存4G以上，加一块20G的额外硬盘

2、初始化虚拟机

关闭防火墙/selinux

3、配置yum仓库

需要RHEL7安装光盘仓库，还需要osp光盘。osp光盘中的每一个目录都是一个仓库

二、DNS服务器

1、安装

\[root@vh01 ~\]\# yum install -y bind

2、主配置文件

\[root@vh01 ~\]\# vim /etc/named.conf

listen-on port 53 \{ any; \};

allow-query     \{ any; \};

\[root@vh01 ~\]\# vim /etc/named.rfc1912.zones

zone "tedu.cn" IN \{

type master;

file "tedu.cn.zone";

allow-update \{ none; \};

\};

3、区配置文件

\[root@vh01 ~\]\# vim /var/named/tedu.cn.zone

$TTL    86400

@       IN      SOA     vh01.tedu.cn.   root.tedu.cn. (

20171101

15M

1D )

IN      NS      vh01.tedu.cn.

$generate       1-9     vh0$    IN      A       192.168.4.$

$generate       10-254  vh$     IN      A       192.168.4.$

4、检查语法

\[root@vh01 ~\]\# named-checkconf /etc/named.conf

\[root@vh01 ~\]\# named-checkconf /etc/named.rfc1912.zones

\[root@vh01 ~\]\# named-checkzone tedu.cn /var/named/tedu.cn.zone

5、验证

\[root@vh01 ~\]\# systemctl start named

\[root@vh01 ~\]\# systemctl enable named

\[root@vh02 ~\]\# nslookup vh01.tedu.cn

NTP配置

1、网络时间协议  UDP123

\[root@vh01 ~\]\# yum install -y ntp

\[root@vh01 ~\]\# vim /etc/ntp.conf

restrict 192.168.4.0 mask 255.255.255.0 nomodify

\#server 0.rhel.pool.ntp.org iburst

\#server 1.rhel.pool.ntp.org iburst

\#server 2.rhel.pool.ntp.org iburst

\#server 3.rhel.pool.ntp.org iburst

server 127.127.1.0 iburst

fudge 127.127.1.0 stratum 3    \#第三层NTP服务器

2、测试

\[root@vh01 ~\]\# systemctl start ntpd

\[root@vh01 ~\]\# systemctl enable ntpd

\[root@vh01 ~\]\# netstat -ulnp | grep :123

\[root@vh02 ~\]\# date

\[root@vh01 ~\]\# date -s "2017-11-28 15:34:00"

\[root@vh02 ~\]\# ntpdate 192.168.4.1

\[root@vh02 ~\]\# date

配置OPENSTACK

1、关闭NetworkManager

\[root@vh02 ~\]\# systemctl stop NetworkManager

\[root@vh02 ~\]\# systemctl disable NetworkManager

2、创建名为cinder-volumes的卷组，用于为云主机提供云硬盘

\[root@vh02 ~\]\# pvcreate /dev/vdb

\[root@vh02 ~\]\# vgcreate cinder-volumes /dev/vdb

3、导公钥、安装rpm包

\[root@vh02 ~\]\# cd openstack/

\[root@vh02 openstack\]\# rpm --import rabbitmq-signing-key-public.asc

\[root@vh02 openstack\]\# yum install -y rpms/\*rpm

4、安装openstack部署工具packstack

\[root@vh02 openstack\]\# yum install -y openstack-packstack

5、生成应答文件

\[root@vh02 openstack\]\# packstack --gen-answer-file answer.txt

\[root@vh02 openstack\]\# vim answer.txt

CONFIG\_DEFAULT\_PASSWORD=redhat

CONFIG\_SWIFT\_INSTALL=n

CONFIG\_NTP\_SERVERS=192.168.4.1

ONFIG\_KEYSTONE\_ADMIN\_PW=redhat

CONFIG\_CINDER\_VOLUMES\_CREATE=n

CONFIG\_NEUTRON\_ML2\_VXLAN\_GROUP=239.1.1.2

CONFIG\_NEUTRON\_ML2\_VNI\_RANGES=1001:2000

CONFIG\_NEUTRON\_OVS\_BRIDGE\_MAPPINGS=physnet1:br-ex

CONFIG\_NEUTRON\_OVS\_TUNNEL\_IF=eth1

CONFIG\_PROVISION\_DEMO=n

6、安装openstack

\[root@vh02 openstack\]\# packstack --answer-file answer.txt

网络配置

\[root@vh02 openstack\]\# cd /etc/sysconfig/network-scripts/

\[root@vh02 network-scripts\]\# cp ifcfg-eth0 ifcfg-br-ex

\[root@vh02 network-scripts\]\# vim ifcfg-br-ex

TYPE=OVSBridge

DEVICETYPE=ovs

BOOTPROTO=none

NAME=br-ex

DEVICE=br-ex

ONBOOT=yes

IPADDR=192.168.4.2

PREFIX=24

DNS1=192.168.4.1

\[root@vh02 network-scripts\]\# vim ifcfg-eth0

TYPE=OVSPort

OVS\_BRIDGE=br-ex

DEVICE=eth0

ONBOOT=yes

DEVICETYPE=ovs

\[root@vh02 network-scripts\]\# systemctl restart network

\[root@room8pc16 cloud\]\# firefox http://192.168.4.2 &

http://mirrors.163.com/

http://mirrors.aliyun.com/

IaaS：云主机

PaaS：组件、中间件

SaaS：软件

Horizon：Web管理门户

Keystone：认证管理

Cinder：云硬盘

Glance：镜像管理

Neutron：网络管理

Nova：云主机管理

手工引导

1、重起系统后，在第一个菜单上按c

2、设置根分区

grub> set root=(hd0,msdos1)   相当于是vda1

3、指定内核

grub> linux16 /vmlinuz-3.10<tab> root=/dev/rhel/root

4、指定初始化内存盘的位置

grub> initrd16 /initamfs-3.10<tab>.img

5、起动

grub> boot

查看状态，active和inactive都是正常的，failed是有问题的

\[root@vh02 ~(keystone\_admin)\]\# openstack-status

重启openstack

\[root@vh02 ~(keystone\_admin)\]\# openstack-service restart

安装额外计算节点

1、vh03.tedu.cn

192.168.4.3/24  192.168.2.3/24  dns: 192.168.4.1

防火墙/selinux

\[root@vh02 ~\]\# scp /etc/yum.repos.d/rhel7.repo 192.168.4.3:/etc/yum.repos.d/

\[root@vh02 ~\]\# scp /etc/yum.repos.d/osp8.repo 192.168.4.3:/etc/yum.repos.d/

\[root@vh02 ~\]\# scp -r openstack/ 192.168.4.3:/root

\[root@vh03 ~\]\# cd openstack/

\[root@vh03 openstack\]\# rpm --import rabbitmq-signing-key-public.asc

\[root@vh03 openstack\]\# yum install -y rpms/\*rpm

\[root@vh02 openstack(keystone\_admin)\]\# vim answer.txt

CONFIG\_COMPUTE\_HOSTS=192.168.4.2,192.168.4.3

\[root@vh02 openstack(keystone\_admin)\]\# packstack --answer-file answer.txt
