一、准备工作
创建两台虚拟机：linux-node1、linux-node2
node1：
修改主机名
[root@localhost ~]# hostnamectl set-hostname linux-node1.example.com
[root@localhost ~]# su -
Last login: Sat May 19 18:28:37 CST 2018 from 192.168.43.1 on pts/0
[root@linux-node1 ~]#
配置IP：
[root@linux-node1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens32
TYPE=Ethernet
BOOTPROTO=static
NAME=ens32
DEVICE=ens32
ONBOOT=yes
IPADDR=192.168.43.11
NETMASK=255.255.255.0
GATEWAY=192.168.43.2
DNS1=192.168.43.2
关闭防火墙、永久关闭selinux：
[root@linux-node1 ~]# systemctl disable NetworkManager
[root@linux-node1 ~]# systemctl disable firewalld
[root@linux-node1 ~]# setenforce 0
[root@linux-node1 ~]# vi /etc/selinux/config
修改hosts文件：
[root@linux-node1 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.43.11 linux-node1 linux-node1.example.com
192.168.43.12 linux-node2 linux-node2.example.com
配置yum源：
[root@linux-node1 ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
[root@linux-node1 ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@linux-node1 ~]# yum makecache
[root@linux-node1 ~]# yum install wget -y
[root@linux-node1 ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
安装常用工具包：
[root@linux-node1 ~]# yum install -y net-tools vim lrzsz tree screen lsof tcpdump nc mtr nmap
以上的环境都接下来把linux-node1克隆：
然后我们就只修改node2的主机名、IP：
[root@linux-node1 ~]# hostnamectl set-hostname linux-node2.example.com
[root@linux-node1 ~]# su -
Last login: Sat May 19 18:51:51 CST 2018 from 192.168.43.1 on pts/0
[root@linux-node2 ~]#
[root@linux-node2 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens32
TYPE=Ethernet
BOOTPROTO=static
NAME=ens32
DEVICE=ens32
ONBOOT=yes
IPADDR=192.168.43.12
NETMASK=255.255.255.0
GATEWAY=192.168.43.2
DNS1=192.168.43.2
node1上操作：

2.修改MySQL配置文件
[root@linux-node1 ~]# vim /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 192.168.43.11 #设置监听的IP地址
default-storage-engine = innodb #设置默认的存储引擎
innodb_file_per_table = on#使用独享表空间
collation-server = utf8_general_ci #服务器的默认校对规则
character-set-server = utf8 #服务器安装时指定的默认字符集设定
max_connections = 4096 #设置MySQL的最大连接数，生产请根据实际情况设置。
3.启动MySQL Server并设置开机启动
[root@linux-node1 ~]# systemctl enable mariadb.service
[root@linux-node1 ~]# systemctl start mariadb.service
4.进行数据库安全设置
[root@linux-node1 ~]# mysql_secure_installation
5.数据库创建
[root@linux-node1 ~]# mysql -u root -p
Enter password:
…
MariaDB [(none)]>
Keystone数据库

7.Glance服务注册
想要让别的服务可以使用Glance，就需要在Keystone上完成服务的注册。注意需要先source一下admin的环境变量。
[root@linux-node1 ~]# source admin-openstack.sh
# openstack service create --name glance --description "OpenStack Image service" image
# openstack endpoint create --region RegionOne image public http://192.168.43.11:9292

8.测试Glance状态
[root@linux-node1 ~]# source admin-openstack.sh
[root@linux-node1 ~]# openstack image list
9.Glance镜像
在刚开始实施OpenStack平台阶段，如果没有制作镜像。可以使用一个实验的镜像进行测试，这是一个小的Linux系统。
[root@linux-node1 ~]# cd /usr/local/src
[root@linux-node1 src]# wget http://download.cirros-cloud.n ... k.img
[root@linux-node1 src]# openstack image create "cirros" --disk-format qcow2 \

14.同步nova数据库
[root@linux-node1 ~]# su -s /bin/sh -c "nova-manage db sync" nova
15.验证cell0和cell1的注册是否正确
[root@linux-node1 ~]# nova-manage cell_v2 list_cells
16.测试数据库同步情况

# systemctl start openstack-nova-api.service \
openstack-nova-consoleauth.service \
openstack-nova-scheduler.service openstack-nova-conductor.service \
openstack-nova-novncproxy.service
11.Nova服务注册
# source admin-openstack.sh # openstack service create --name nova --description "OpenStack Compute" compute
# openstack endpoint create --region RegionOne compute public http://192.168.43.11:8774/v2.1
# openstack endpoint create --region RegionOne compute internal http://192.168.43.11:8774/v2.1 # openstack endpoint create --region RegionOne compute admin http://192.168.43.11:8774/v2.1
# openstack service create --name placement --description "Placement API" placement
# openstack endpoint create --region RegionOne placement public http://192.168.43.11:8778
# openstack endpoint create --region RegionOne placement internal http://192.168.43.11:8778
# openstack endpoint create --region RegionOne placement admin http://192.168.43.11:8778

删掉多余配置：
[root@linux-node2 ~]# vim /etc/nova/nova.conf
connection=mysql+pymysql://nova:[email protected]/nova_api
connection=mysql+pymysql://nova:[email protected]/nova
2.修改VNC配置
计算节点需要监听所有IP，同时设置novncproxy的访问地址
[vnc]
enabled=true
server_listen = 0.0.0.0
server_proxyclient_address = 192.168.43.12
novncproxy_base_url = http://192.168.43.11:6080/vnc_auto.html
3.虚拟化适配
[root@linux-node2 ~]# egrep -c '(vmx|svm)' /proc/cpuinfo
[libvirt]
virt_type=qemu
如果返回的是非0的值，那么表示计算节点服务器支持硬件虚拟化，需要在nova.conf里面设置
[libvirt]
virt_type=kvm

1.Keystone连接配置
[root@linux-node2 ~]# vim /etc/neutron/neutron.conf
[DEFAULT]
…
auth_strategy = keystone
[keystone_authtoken]
auth_uri = http://192.168.43.11:5000
auth_url = http://192.168.43.11:35357
memcached_servers = 192.168.43.11:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron
2.RabbitMQ相关设置
[root@linux-node2 ~]# vim /etc/neutron/neutron.conf
[DEFAULT]
transport_url = rabbit://openstack:[email protected] #请注意是在DEFAULT配置栏目下，因为该配置文件有多个transport_url的配置
3.锁路径
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
4.配置LinuxBridge配置
[root@linux-node1 ~]# scp /etc/neutron/plugins/ml2/linuxbridge_agent.ini 192.168.43.12:/etc/neutron/plugins/ml2/
5.设置计算节点的nova.conf
[root@linux-node2 ~]# vim /etc/nova/nova.conf
[neutron]
url = http://192.168.43.11:9696
auth_url = http://192.168.43.11:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron
重启计算服务
[root@linux-node2 ~]# systemctl restart openstack-nova-compute.service
启动计算节点linuxbridge-agent
[root@linux-node2 ~]# systemctl enable neutron-linuxbridge-agent.service
[root@linux-node2 ~]# systemctl start neutron-linuxbridge-agent.service
在控制节点上测试Neutron安装
[root@linux-node1 ~]# source admin-openstack.sh
[root@linux-node1 ~]# openstack network agent list
使用命令创建云主机；后者也可以通过web界面创建
1.创建网络
[root@linux-node1 ~]# openstack network create --share --external \
--provider-physical-network provider \
--provider-network-type flat provider
2.创建子网
[root@linux-node1 ~]# openstack subnet create --network provider \
--allocation-pool start=192.168.43.100,end=192.168.43.200 \
--dns-nameserver 223.5.5.5 --gateway 192.168.43.2 \
--subnet-range 192.168.43.0/24 provider-subnet
3. 创建云主机类型
[root@linux-node1 ~]# openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano
4.创建密钥对
[root@linux-node1 ~]# source demo-openstack.sh
[root@linux-node1 ~]# ssh-keygen -q -N ""
[root@linux-node1 ~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey [root@linux-node1 ~]# openstack keypair list
5.添加安全组规则
[root@linux-node1 ~]# openstack security group rule create --proto icmp default
[root@linux-node1 ~]# openstack security group rule create --proto tcp --dst-port 22 default
启动实例
[root@linux-node1 ~]# source demo-openstack.sh
[root@linux-node1 ~]# openstack flavor list
1.查看可用的镜像
[root@linux-node1 ~]# openstack image list
2.查看可用的网络
[root@linux-node1 ~]# openstack network list
3.查看可用的安全组
[root@linux-node1 ~]# openstack security group list
4.创建虚拟机
[root@linux-node1 ~]# openstack server create --flavor m1.nano --image cirros \
--nic net-id=5c4d0706-24cd-4d42-ba78-36a05b6c81c8 --security-group default \
--key-name mykey demo-instance #注意指定网络的时候需要使用ID，而不是名称
5.查看虚拟机
[root@linux-node1 ~]# openstack server list
[root@linux-node1 ~]# openstack console url show demo-instance
安装Horizon服务
1.安装Horizon
[root@linux-node2 ~]# yum install -y openstack-dashboard
2.Horizon配置
[root@linux-node2 ~]# vim /etc/openstack-dashboard/local_settings
