环境：
安装消息队列rabbitMQ
安装调整缓存服务
安装etcd服务
安装keystone认证服务
glance安装
安装nova计算服务
安装Neutron网络服务
- 创建neutron认证服务
安装neutron网络组件
安装dashboard面板
- 重启服务
- 检查dashboard可用

环境：

一台控制节点两台计算节点的名称和ip地址：

	版本
centos	7.9
manager（controller）	192.168.80.143
master（compute）	192.168.80.144
worker（compute)	192.168.80.145

设置主机名

#控制节点
hostnamectl set-hostname manager.node
#计算节点1
hostnamectl set-hostname master.node
#计算节点2
hostnamectl set-hostname worker.node

配置域名和IP映射

编辑/etc/hosts文件

cat >> /etc/hosts <<EOF
192.168.80.143 manager.node
192.168.80.144 master.node
192.168.80.145 worker.node

域名解析

nameserver 8.8.8.8
nameserver 8.8.4.4

时间同步

manager对所有节点免密登陆
只需manager节点执行

#一直回车就可以
ssh-keygen -t rsa

分别分发到各个节点

ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.80.143
ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.80.144

配置OpenStack-rocky的yum源文件

官网是yum安装centos-release-openstack-rocky，用的是国外的源，会比较慢，手动配置阿里的源

cat <<EOF >  /etc/yum.repos.d/openstack.repo
[openstack-rocky]
name=openstack-rocky
baseurl=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-rocky/
enabled=1
gpgcheck=0
[qume-kvm]
name=qemu-kvm

可在manager节点创建后将该文件分发到所有其它节点

#发送给计算节点1
scp /etc/yum.repos.d/openstack.repo master.node:/etc/yum.repos.d/
#发送给计算节点2
scp /etc/yum.repos.d/openstack.repo worker.node:/etc/yum.repos.d/

安装数据库mariadb

只需要在manager节点操作

yum install -y mariadb mariadb-server python2-PyMySQL

cat <<EOF >  /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 192.168.80.143

验证 grep '^[a-z]' /etc/nova/nova.conf

查看该计算节点是否支持虚拟化

egrep -c '(vmx|svm)' /proc/cpuinfo
1

0说明不支持硬件加速，需要额外的配置
1或更大则无需操作
此处为0，仍然打开nova.conf文件进行编辑

openstack-config --set  /etc/nova/nova.conf libvirt virt_type  qemu
1

如果是通过Exsi创建的虚拟机，那么需要把虚拟机电源关闭，编辑设置中，把cpu选项的虚拟化功能开启。
在这里插入图片描述
之后再启动虚拟机，查看

[root@manager opt]# egrep -c '(vmx|svm)' /proc/cpuinfo

安装Neutron网络服务

以下在manager节点（controller）操作
创建neutron数据库，并赋权

CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY '123456';
flush privileges;

创建neutron网络服务的API端点（endpoint）

openstack endpoint create --region RegionOne network public http://manager.node:9696
openstack endpoint create --region RegionOne network internal http://manager.node:9696
openstack endpoint create --region RegionOne network admin http://manager.node:9696
