说明:

本教程安装QueenS版本的OpenStack,采用all in one的方式安装(即:所有组件均安装在同一个机器上)。

本教程亲测可用,已经部署完成。


1、搭建基础环境


1.1、安装VMWare

使用VMWare16 pro版本,下载地址:

vmware.com/cn/products/

1.2、下载CentoOS7

使用CentOS7系统,下载地址:

vmware.com/cn/products/

1.3、安装虚拟机

虚拟机配置如下:

  • RAM:大于10GB,否则OpenStack安装完成后,虚拟机运行会卡顿。

  • ROM:100GB,分两块磁盘,sda用于存放CentOS系统,sdb用于存放LVM(cinder的数据卷)。

  • 网卡:enss33用于虚拟机访问网络,enss37用于OpenStack组件之间的通信(all in one的方式,实际上不需要用到enss37网卡)。

2、准备工作


2.1、禁用SELinux

作用:不禁用SELinux可能会导致openstack newton Apache无法启动。

错误如下:"Devstack fail to start apache2 -“Address already in use”:“coild not bind to address”

解决方式:配置/etc/selinux/config,关闭SELINUX。

[root@controller /]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

2.2、关闭防火墙

作用:免去配置OpenStack各个节点时,需要不断手动开启端口的麻烦。但是在实际生产环境中绝对不允许这样做,这会引起安全问题。

[root@controller ~]# systemctl stop firewalld 
[root@controller ~]# systemctl disable firewalld


2.3、配置网卡

CentOS系统默认使用DHCP(动态主机配置协议)分配网卡IP。此处,建议使用static(静态)网卡IP,因为在VMWare的虚拟机重启之后,虚拟机的网卡IP可能会变化,这就会导致OpenStack其他节点配置的网卡IP无法使用。

查看当前网卡IP:

[root@controller /]# ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.83.139  netmask 255.255.255.0  broadcast 192.168.83.255
        inet6 fe80::c62f:bd78:ba20:b81  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:5b:0e:1c  txqueuelen 1000  (Ethernet)
        RX packets 15733  bytes 10884363 (10.3 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 11840  bytes 6242032 (5.9 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0


配置网卡IP:

[root@controller /]# cat /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=038e74ab-c77d-4f83-b67b-dabde3a03c1d
DEVICE=ens33
#更改的部分
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.83.139
GATEWAY=192.168.83.2
NETMASK=255.255.255.0
DNS1=114.114.114.114


若需要配置第二张网卡enss37,则将上面的NAME、DEVICE更改后,删除UUID,并配置新的IPADDR,即可。

2.4、配置主机名

#设置主机名
[root@controller ~]# hostnamectl set-hostname controller 
#查看设置
[root@controller ~]# hostname 
controller 
#修改hosts文件:controller域名,解析时指向本机的网卡IP
[root@controller ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.83.139 controller


2.5、设置时区

[root@controller ~]# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime cp: overwrite ‘/etc/localtime’? y 
[root@controller ~]# date Tue Jul 20 16:13:44 CST 2021


3、安装软件


注意:安装软件时,如果出现安装失败的情况,可能是因为网络原因导致的。只需要再次执行安装命令即可。

3.1、安装NTP

用于同步各个节点的时间。需要安装Chrony,通常情况下安装在控制器节点,其他节点则同步控制节点的时间,来达到各个节点时间一致的效果。

#安装chrony
[root@controller /]# yum install chrony -y
#配置(可选)
[root@controller /]# vim /etc/chrony.conf
server 0.centos.pool.ntp.org iburst
#启动软件、设置开机启动
[root@controller /]# systemctl start chronyd.service
[root@controller /]# systemctl enable chronyd.service


3.2、添加OpenStack软件源

网络上发布的OpenStack存在多个不同版本,eg:Victoria、Queens、Train等。本次使用的时Queens版本。

#添加Queens版本源
[root@controller ~]# yum install centos-release-openstack-queens -y 
#升级软件包
[root@controller ~]# yum upgrade -y
#安装OpenStack Client
[root@controller ~]# yum install python-openstackclient -y


3.3、安装SQL数据库

通常情况下,数据库安装在控制节点上,用于存储OpenStack的数据。

#安装SQL
[root@controller ~]# yum install mariadb mariadb-server python2-PyMySQL -y
#配置SQL
[root@controller /]# vim /etc/my.cnf.d/openstack.cnf
[mysqld]
#修改为本机的网卡IP
bind-address = 192.168.83.139
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
#设置开机自启、启动SQL
[root@controller /]# systemctl enable mariadb.service
[root@controller /]# systemctl start mariadb.service
#设置SQL数据库的root账号、密码
[root@controller /]# mysql_secure_installation

3.4、安装消息队列

消息队列服务通常安装在控制器节点上。用于协调服务之间的操作和状态信息。

#安装MQ[root@controller /]# yum install rabbitmq-server#设置开机自启、启动MQ[root@controller /]# systemctl enable rabbitmq-server.service[root@controller /]# systemctl start rabbitmq-server.service#添加MQ用户,设置密码[root@controller /]# rabbitmqctl add_user openstack RABBIT_PASS#允许openstack用户进行配置、写入和读取访问[root@controller /]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"


3.5、安装Memcached

Memcached服务通常安装在控制器节点上。服务的身份服务认证机制使用 Memcached来缓存token令牌。

#安装
[root@controller /]# yum install memcached python-memcached
#配置
[root@controller /]# vim /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
#新增controller域名,其他节点可以通过该域名直接访问
OPTIONS="-l 127.0.0.1,::1,controller"
#设置开机自启、启动软件
[root@controller /]# systemctl enable memcached.service
[root@controller /]# systemctl start memcached.service


3.6、安装ETCD数据库

用于分布式密钥锁定、存储配置、跟踪服务实时性和其他场景:

#安装etcd[root@controller /]# yum install etcd#配置etcd:#ETCD_INITIAL_CLUSTER, ETCD_INITIAL_ADVERTISE_PEER_URLS, ETCD_ADVERTISE_CLIENT_URLS,ETCD_LISTEN_CLIENT_URLS设置为控制节点的IP(即:本机的网卡IP)[root@controller /]# vim /etc/etcd/etcd.conf[Member]ETCD_DATA_DIR="/var/lib/etcd/default.etcd"ETCD_LISTEN_PEER_URLS="http://192.168.83.139:2380"ETCD_LISTEN_CLIENT_URLS="http://localhost:2379,http://192.168.83.139:2379"ETCD_NAME="controller"[Clustering]ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.83.139:2380"ETCD_ADVERTISE_CLIENT_URLS="http://192.168.83.139:2379"ETCD_INITIAL_CLUSTER="controller=http://192.168.83.139:2380"ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01"ETCD_INITIAL_CLUSTER_STATE="new"#设置开机自启、启动软件[root@controller /]# systemctl enable etcd[root@controller /]# systemctl start etcd


4、安装OpenStack


注意:本次安装的是Queens版本。

4.1、默认密码

本次安装OpenStack所有的组件,均使用默认密码。

WX20221219-152730@2x.png


4.2、安装Keystone

4.2.1、安装Keystone步骤

作用:用于管理身份验证、授权和服务目录。通过身份验证后,最终用户可以使用他们的身份访问其他OpenStack服务。

创建数据库:

#登录数据库
[root@controller /]# mysql -u root -p
#创建keystone数据库
MariaDB [(none)]> CREATE DATABASE keystone;
#用户登录授权
#本地登录
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY 'KEYSTONE_DBPASS';
#远程登录
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY 'KEYSTONE_DBPASS';


安装、配置keystone:

#安装软件[root@controller /]# yum install openstack-keystone httpd mod_wsgi#配置keystone.conf[root@controller /]# vim /etc/keystone/keystone.conf [database]connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone[token]provider = fernet#填充keystone数据库[root@controller /]# su -s /bin/sh -c "keystone-manage db_sync" keystone#初始化Fernet密钥库[root@controller /]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone[root@controller /]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone#引导身份服务[root@controller /]# keystone-manage bootstrap --bootstrap-password ADMIN_PASS \                      --bootstrap-admin-url http://controller:5000/v3/ \                      --bootstrap-internal-url http://controller:5000/v3/ \                      --bootstrap-public-url http://controller:5000/v3/ \                      --bootstrap-region-id RegionOne

配置Apache HTTP服务:

#配置httpd.conf
[root@controller /]# vim /etc/httpd/conf/httpd.conf
ServerName controller
#创建软链接
[root@controller /]# /usr/share/keystone/wsgi-keystone.conf


配置系统环境:

[root@controller /]# systemctl enable httpd.service
[root@controller /]# systemctl start httpd.service
#配置管理账户
[root@controller /]# export OS_USERNAME=admin \
 export OS_PASSWORD=ADMIN_PASS \
 export OS_PROJECT_NAME=admin \

+------------+-----------------------------------------------------------------+


4.2.3、创建OpenStack客户端脚本

为什么需要使用脚本?

由于之前,配置系统环境时,使用的是export命令,该命令用于临时配置环境变量,当系统重启或者执行export明令的终端关闭后,该环境变量就无法使用了,导致openstack命令无法被执行。

需要创建的脚本如下:

为管理(admin)和演示(demo)项目以及用户创建客户端环境脚本。即:获取相应权限的CLI命令(Command Line Interface),通过命令的方式进行交互。这两个脚本可以存放在同一个目录中。

admin-openrc:

export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=ADMIN_PASS
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2


demo-openrc:

export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=DEMO_PASS
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2


使用脚本的方式:

[root@controller /]# . admin-openrc
#请求身份验证令牌
[root@controller /]# openstack token issue
+------------+-----------------------------------------------------------------+
| Field      | Value                                                           |
+------------+-----------------------------------------------------------------+
| expires    | 2016-02-12T20:44:35.659723Z                                     |
| id         | gAAAAABWvjYj-Zjfg8WXFaQnUd1DMYTBVrKw4h3fIagi5NoEmh21U72SrRv2trl |

| user_id    | ac3377633149401296f6c0d92d79dc16                                |
+------------+-----------------------------------------------------------------+


4.3、安装Glance

4.3.1、安装Glance步骤

作用:提供发现、注册和检索虚拟机镜像的功能。

创建数据库:

#登录数据库
[root@controller /]# mysql -u root -p
#创建glance数据库
MariaDB [(none)]> CREATE DATABASE glance;
#授权
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
  IDENTIFIED BY 'GLANCE_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
  IDENTIFIED BY 'GLANCE_DBPASS';


获取管理员的CLI命令:

[root@controller /]# . admin-openrc


创建服务凭证:用户、角色信息,镜像服务端点:

#创建glance用户
[root@controller /]# openstack user create --domain default --password-prompt glance
#此处使用默认密码:GLANCE_PASS
User Password:
Repeat User Password:
+---------------------+----------------------------------+

#进入数据库
[root@controller /]# mysql -u root -p
#创建数据库
MariaDB [(none)]> CREATE DATABASE nova_api;
MariaDB [(none)]> CREATE DATABASE nova;
MariaDB [(none)]> CREATE DATABASE nova_cell0;
#数据库授权
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \
  IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \
  IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
  IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \
  IDENTIFIED BY 'NOVA_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' \
