0、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
  • OpenStack官网安装手册：https://docs.openstack.org/install-guide/

1、搭建基础环境

1.1、安装VMWare

使用VMWare16 pro版本，下载地址：https://www.vmware.com/cn/products/workstation-pro/workstation-pro-evaluation.html

1.2、下载CentoOS7

1.3、安装虚拟机

  • 安装教程：
  • 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

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

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

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:

WSGIApplicationGroup %{GLOBAL}
  • 配置环境
#重启httpd、memcached服务
[root@controller /]# systemctl restart httpd.service memcached.service

4.6.2、验证是否成功安装

  • 在浏览器，登录下面的地址
#方式1：
http://controller/dashboard

#方式2：
http://本机网卡IP/dashboard
  • 登录选项
  • domain：default
  • username：admin
  • password：ADMIN_PASS
  • 结果

4.7、安装Cinder

4.7.1、安装、配置存储节点

  • 安装LVM
[root@controller /]# yum install lvm2 device-mapper-persistent-data

#设置开机自启动
[root@controller /]# systemctl enable lvm2-lvmetad.service
[root@controller /]# systemctl start lvm2-lvmetad.service
  • 创建LVM物理卷
    注意：此处的sdb，表示的是第二块硬盘。（同理，sda表示第一块硬盘）
[root@controller /]# pvcreate /dev/sdb
Physical volume "/dev/sdb" successfully created
  • 创建 LVM 卷组cinder-volumes：
[root@controller /]# vgcreate cinder-volumes /dev/sdb
Volume group "cinder-volumes" successfully created
  • 配置lvm.conf
[root@controller /]# vim /etc/lvm/lvm.conf
#设置过滤器，a：接受。 r：拒绝
#下面的filter，只需要选择一个进行配置即可。

#存储节点使用LVM （本教程使用这个）
filter  =  [ "a/sda/", "a/sdb/", "r/.*/"]

#计算节点使用LVM
filter  =  [ "a/sda/", "r/.*/"]
  • 安装cinder组件
[root@controller /]# yum install openstack-cinder targetcli python-keystone
  • 配置cinder.conf
[root@controller /]# vim /etc/cinder/cinder.conf
[database]
connection = mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder

[DEFAULT]
transport_url = rabbit://openstack:RABBIT_PASS@controller
auth_strategy = keystone

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = CINDER_PASS

[DEFAULT]
#配置为本机的网卡IP
my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm

[DEFAULT]
enabled_backends = lvm
glance_api_servers = http://controller:9292

[oslo_concurrency]
lock_path = /var/lib/cinder/tmp
  • 配置环境
[root@controller /]# systemctl enable openstack-cinder-volume.service target.service
[root@controller /]# systemctl start openstack-cinder-volume.service target.service

4.7.2、安装、配置控制节点

在控制器节点上安装和配置块存储服务.

  • 创建数据库
#进入数据库
[root@controller /]# mysql -u root -p

#创建cinder数据库
MariaDB [(none)]> CREATE DATABASE cinder;

#数据库授权
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
  IDENTIFIED BY 'CINDER_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
  IDENTIFIED BY 'CINDER_DBPASS';
  • 创建服务凭证
#获取管理员的CLI命令
[root@controller /]# . admin-openrc

#创建cinde用户
[root@controller /]#openstack user create --domain default --password-prompt cinder
#此处使用默认密码：CINDER_PASS
User Password:

4.7.3、（可选）安装、配置备份服务

本教程没有安装swift组件，因此可省略此步骤

  • 安装cinder
[root@controller /]# yum install openstack-cinder
  • 配置cinder.conf
[root@controller /]# /etc/cinder/cinder.conf
[DEFAULT]

5、常见问题

1、安装keystone后，执行命令：openstack domain create --description “An Example Domain” example

出现错误：

Failed to discover available identity versions when contacting http://controller:5000/v3. Attempting to parse version from URL.
Unable to establish connection to http://controller:5000/v3/auth/tokens: HTTPConnectionPool(host='controller', port=5000): Max retries exceeded with url: /v3/auth/tokens (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fa20bba02b0>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution',))

解决方式：

关闭SELinux，然后使用命令setnforce 0（或者重启系统）

2、配置网卡时，需要注意的事项

配置网络时，需要先使用dhcp，获取虚拟机网卡ip，然后再使用static的方式，配置网卡ip。如果直接使用dhcp的方式，可能会导致该ip无法使用，无法ping通。

3.2、安装OpenStack各个组件时，使用命令： yum install xxxx -y。

出现错误：

Error downloading packages:
  python-dogpile-cache-0.6.2-1.el7.noarch: [Errno 256] No more mirrors to try.
  python-keyring-5.7.1-1.el7.noarch: [Errno 256] No more mirrors to try.
  python-dogpile-core-0.4.1-2.el7.noarch: [Errno 256] No more mirrors to try.
  python-cmd2-0.6.8-8.el7.noarch: [Errno 256] No more mirrors to try.

解决方式：
（1）方式1：再次执行安装命令 yum install python-openstackclient -y
（2）方式2：yum update =》yum install python-openstackclient -y
若还是出现错误：Error downloading packages: lttng-ust-2.10.0-1.el7.x86_64: [Errno 256] No more mirrors to try.
使用yum clean cache、yum makecache，然后再次进行yum update

4、horizon登录注意事项
地址：http://controller/dashboard
不行的话，换成: http://controller对用的IP地址/dashboard
登录填写的资料：
domain：default
username：admin
password：ADMIN_PASS

5、禁用 SELinux

  • **否则会出现错误：**the request you have made requires authentication(HTTPConnection 401)
  • 解决方式：
[root@controller /]# vim /etc/selinux/config
SELINUX=disabled 
SELINUXTYPE=targeted

然后setnforce 0（或者重启系统）

6、VMWare挂载磁盘的注意事项
查看挂载：

[root@controller /]# fdisk -l

若新增的磁盘未挂载上，处理方式：

#1、查看当前有的磁盘文件：
[root@controller /]# cd /sys/class/scsi_host/ 

#2、获取当前目录下的所有文件名
[root@controller /]# ls
host0 host1 host2

#3、逐个执行上面文件中出现的文件
[root@controller /]# echo "- - -" >  /sys/class/scsi_host/host0/scan
[root@controller /]# echo "- - -" >  /sys/class/scsi_host/host1/scan
[root@controller /]# echo "- - -" >  /sys/class/scsi_host/host2/scan

7、重启虚拟机后，无法使用openstack命令

  • 原因：
    因为使用export设置环境变量，因此该环境变量只限定于当前执行命令的终端使用。系统关机、开启新的终端均无法使用这个环境变量。
  • 解决方式：
    需要运行源文件命令，添加环境变量。
[root@controller /]# . admin-openrc
#admin-openrc文件中的内容
[root@controller /]# vim 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

8、执行openstack volume service list，cinder-volume运行失败

  • 原因：
    若，存储节点在操作系统磁盘上使用LVM，则需要将关联的设备添加到过滤器中。
  • 解决方式：
    配置存储节点时，需要挂载相应的卷。
#修改配置文件：/etc/lvm/lvm.conf
[root@controller /]# vim /etc/lvm/lvm.conf
devices {
...
filter = [ "a/sda/", "a/sdb/", "r/.*/"]
}

9、Nova无法启动

  • 原因：
    防火墙阻止访问5672端口
  • 解决方式：
#查看nova-comput日志：发现端口未启用
cat /var/log/nova/nova-compute.log

#关闭防火墙
systemctl stop firewalld
systemctl disable firewalld

#重启nova服务
systemctl start libvirtd.service openstack-nova-compute.service

执行安装命令 yum install python-openstackclient -y
（2）方式2：yum update =》yum install python-openstackclient -y
若还是出现错误：Error downloading packages: lttng-ust-2.10.0-1.el7.x86_64: [Errno 256] No more mirrors to try.
使用yum clean cache、yum makecache，然后再次进行yum update

4、horizon登录注意事项
地址：http://controller/dashboard
不行的话，换成: http://controller对用的IP地址/dashboard
登录填写的资料：
domain：default
username：admin
password：ADMIN_PASS

5、禁用 SELinux

  • **否则会出现错误：**the request you have made requires authentication(HTTPConnection 401)
  • 解决方式：
[root@controller /]# vim /etc/selinux/config
SELINUX=disabled 
SELINUXTYPE=targeted

然后setnforce 0（或者重启系统）

6、VMWare挂载磁盘的注意事项
查看挂载：

[root@controller /]# fdisk -l

若新增的磁盘未挂载上，处理方式：

#1、查看当前有的磁盘文件：
[root@controller /]# cd /sys/class/scsi_host/ 

#2、获取当前目录下的所有文件名
[root@controller /]# ls
host0 host1 host2

#3、逐个执行上面文件中出现的文件
[root@controller /]# echo "- - -" >  /sys/class/scsi_host/host0/scan
[root@controller /]# echo "- - -" >  /sys/class/scsi_host/host1/scan
[root@controller /]# echo "- - -" >  /sys/class/scsi_host/host2/scan

  • 原因：
    防火墙阻止访问5672端口
  • 解决方式：
#查看nova-comput日志：发现端口未启用
cat /var/log/nova/nova-compute.log

#关闭防火墙
systemctl stop firewalld
systemctl disable firewalld

#重启nova服务
systemctl start libvirtd.service openstack-nova-compute.service
