逻辑架构

架构设计
参考: https://docs.openstack.org/arch-design

本地测试

本地测试最小资源需求，参考材料：https://docs.openstack.org/install-guide/overview.html

配置
准备基础资源和环境
创建虚拟机或者使用物理服务器。
以虚拟机为例，最低需求，1CPU，2核，50G存储，双网卡，一个桥接，一个NAT，这是最低配置的建议，如果低于这个配置，很多组件将无法安装使用。
按照该最低配置，部署后的内容，不包含存储节点，不包含独立的网络节点，只有一个控制节点和计算节点。
物理服务器，也是双网卡，需要额外的交换机配置，通过vlan区分不同的网络即可。
安装系统可以使用centos7 64bit，最小化安装，关闭kdump，网卡配置IP，第一个网卡配置为管理网络使用的网卡，第二个网卡配置为业务网络使用的网卡。两个网卡的IP地址不同网段，不同vlan即可。
务必保证虚拟机或服务器可以访问到外网，因为安装需要访问外网下载安装包。
网卡样例示意图：

网卡配置
配置文件路径：/etc/sysconfig/network-scripts/ifcfg-INTERFACE_NAME
检查以下配置：
DEVICE=INTERFACE_NAME
TYPE=Ethernet
ONBOOT=“yes”
BOOTPROTO=“none”
这里需要学习过最低水准为RHCSA课程的人员进行操作。因为网卡名字是随机的，这里容易出现理解误差导致操作失败。
网卡中其他配置，如果没有明确的需求，请勿随意改动，IP地址务必自定义配置。请不要自动分配。
控制节点和计算节点都需要进行网卡配置。

配置hosts文件
文件路径：/etc/hosts
配置样例：
#127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
#::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

#controller
192.168.32.132 controller

#compute
192.168.32.133 compute

这里的IP地址是管理网络的IP地址。
控制节点和计算节点都需要进行一样的配置。

配置DNS

vi /etc/resolv.conf

Generated by NetworkManager

nameserver 114.114.114.114
nameserver 8.8.8.8

控制节点和计算节点都需要进行一样的配置。

验证网络连通性
控制节点：

ping -c 4 docs.openstack.org

ping -c 4 compute

计算节点：

ping -c 4 openstack.org

ping -c 4 controller

务必确保都可以ping通。

防火墙

iptables -F

systemctl stop firewalld

如果只是简单的进行使用测试，可以选择关闭防火墙。控制节点和计算节点都配置。

NTP时钟
控制节点：

yum install chrony

编辑配置文件 /etc/chrony.conf
server NTP_SERVER iburst

默认情况下，控制节点就是NTP服务器，给其他节点提供时间同步，这里可以选择外部的NTP时钟源。
配置接入客户端的许可，允许其他节点向本节点申请时间同步。

Allow NTP client access from local network.

#allow 192.168.0.0/16
allow 192.168.32.0/24

启动服务：

systemctl enable chronyd.service

systemctl start chronyd.service

验证
chronyc sources

计算节点：

yum install chrony

编辑配置文件 /etc/chrony.conf
server controller iburst

启动服务

systemctl enable chronyd.service

systemctl start chronyd.service

验证
chronyc sources

添加OpenStack资源仓库

yum install centos-release-openstack-rocky

在控制节点和计算节点都执行。
备注：如果出现安装失败，建议将base源换成国内的，例如华为和阿里的。
更新软件包

yum upgrade

在控制节点和计算节点都执行。

重启节点

reboot

在控制节点和计算节点都执行。

安装OpenStack客户端

yum install python-openstackclient

在控制节点和计算节点都执行。

安装OpenStack的SELinux管理包

yum install openstack-selinux

在控制节点和计算节点都执行。

安装数据库
只在控制节点操作。

yum install mariadb mariadb-server python2-PyMySQL

编辑配置文件
vi /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 192.168.32.132
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

192.168.32.132是指控制节点的管理网络的网卡上的IP

启动服务

systemctl enable mariadb.service

systemctl start mariadb.service

保护数据库

mysql_secure_installation

用密码的方式保护数据库

安装配置消息队列
只在控制节点操作。
安装

yum install rabbitmq-server

开启服务

systemctl enable rabbitmq-server.service

systemctl start rabbitmq-server.service

添加用户

rabbitmqctl add_user openstack qwe123456

qwe123456是rabbitmq的密码。

配置权限

rabbitmqctl set_permissions openstack “." ".” “.*”

安装Memcached
只安装在控制节点

安装

yum install memcached python-memcached

修改配置文件
vi /etc/sysconfig/memcached
OPTIONS="-l 127.0.0.1,::1,controller"

添加关于控制节点的信息，让其他节点可以通过管理网络访问控制节点的服务。

启动服务

systemctl enable memcached.service

systemctl start memcached.service

安装etcd
只安装在控制节点

安装

yum install etcd

修改配置文件

vi /etc/etcd/etcd.conf

#[Member]
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_PEER_URLS=“http://10.0.0.11:2380”
ETCD_LISTEN_CLIENT_URLS=“http://10.0.0.11:2379”
ETCD_NAME=“controller”
#[Clustering]
ETCD_INITIAL_ADVERTISE_PEER_URLS=“http://10.0.0.11:2380”
ETCD_ADVERTISE_CLIENT_URLS=“http://10.0.0.11:2379”
ETCD_INITIAL_CLUSTER=“controller=http://10.0.0.11:2380”
ETCD_INITIAL_CLUSTER_TOKEN=“etcd-cluster-01”
ETCD_INITIAL_CLUSTER_STATE=“new”

10.0.0.11是控制节点管理网络的IP。

启动服务

IDENTIFIED BY ‘qwe123456’;
exit

访问和使用
访问http://192.168.32.132/dashboard
域是default
用户是admin或者demo，密码是qwe123456
效果如图

部署以后，当前是没有存储可以使用的，需要部署cinder：https://docs.openstack.org/cinder/rocky/install/ 总体参考: https://docs.openstack.org/install-guide/openstack-services.html#minimal-deployment-for-rocky

部署Block Storage service

因为需要一个额外的存储节点，需要100G存储空间，以便进行存储使用的操作，当前本地资源不足，这部分暂时不做。
实验暂停。
如果没有存储节点，ECS（弹性伸缩实例，即云主机）是无法正常发放的。
安装结束后，参考https://docs.openstack.org/install-guide/launch-instance.html 进行测试
