说明:此次部署搭建采用三台物理节点手搭建社区openstack Queens环境

二.OpenStack概述

OpenStack项目是一个开源云计算平台,支持所有类型的云环境。该项目旨在实现简单,大规模的可扩展性和丰富的功能。

OpenStack通过各种补充服务提供基础架构即服务(IaaS)解决方案。每项服务都提供了一个应用程序编程接口(API),以促进这种集成。

本文涵盖了使用适用于具有足够Linux经验的OpenStack新用户的功能性示例体系结构,逐步部署主要OpenStack服务。只用于学习OpenStack最小化环境。

三、OpenStack架构总览

1.概念性架构
下图显示了OpenStack服务之间的关系:

社区OpenStack Queens版本部署安装详解

2.逻辑体系结构
下图显示了OpenStack云中最常见但不是唯一可能的体系结构:
社区OpenStack Queens版本部署安装详解
对于设计,部署和配置OpenStack,学习者必须了解逻辑体系结构。
如概念架构所示,OpenStack由几个独立的部分组成,称为OpenStack服务。所有服务都通过keystone服务进行身份验证。

各个服务通过公共API相互交互,除非需要特权管理员命令。

在内部,OpenStack服务由多个进程组成。所有服务都至少有一个API进程,它监听API请求,预处理它们并将它们传递给服务的其他部分。除身份服务外,实际工作由不同的流程完成。
对于一个服务的进程之间的通信,使用AMQP消息代理。该服务的状态存储在数据库中。部署和配置OpenStack云时,您可以选择多种消息代理和数据库解决方案,例如RabbitMQ,MySQL,MariaDB和SQLite。

用户可以通过Horizon Dashboard实现的基于Web的用户界面,通过命令行客户端以及通过浏览器插件或curl等工具发布API请求来访问OpenStack。对于应用程序,有几个SDK可用。最终,所有这些访问方法都会对各种OpenStack服务发出REST API调用。

四.OpenStack组件服务部署

部署前置条件(以下命令在所有节点执行)

1.配置节点网卡IP(略)
2.设置主机名

hostnamectl set-hostname 主机名
bash  ##使设置立即生效

3.配置域名解析,编辑编辑/etc/hosts文件,加入如下配置

10.71.11.12 controller
10.71.11.13 compute
10.71.11.14 cinder

4.验证网络连通性
在控制节点执行

root@controller ~]# ping -c 4 openstack.org
PING openstack.org (162.242.140.107) 56(84) bytes of data.
64 bytes from 162.242.140.107 (162.242.140.107): icmp_seq=1 ttl=46 time=248 ms

注意:日常运维中经常遇见时钟飘逸问题,导致集群服务脑裂

openstack服务安装、配置

说明:无特殊说明,以下操作在所有节点上执行
1.下载安装openstack软件仓库(queens版本)

yum install centos-release-openstack-queens -y

2.更新所有节点软件包

yum upgrade

3.安装openstack client端

yum install python-openstackclient -y

4.安装openstack-selinux

yum install openstack-selinux -y

安装数据库(controller节点执行)

大多数OpenStack服务使用SQL数据库来存储信息,数据库通常在控制器节点上运行。 本文主要使用MariaDB或MySQL。

安装软件包

yum install mariadb mariadb-server python2-PyMySQL -y

编辑/etc/my.cnf.d/mariadb-server.cnf并完成以下操作

[root@controller ~]# vi /etc/my.cnf.d/mariadb-server.cnf

#
# These groups are read by MariaDB server.
# Use it for options that only the server (but not clients) should see
#
# See the examples of server my.cnf files in /usr/share/mysql/
#

# this is read by the standalone daemon and embedded servers
[server]

# this is only for the mysqld standalone daemon
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mysqld/mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
bind-address = 10.71.11.12
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

说明:bind-address使用controller节点的管理IP

设置服务开机启动

systemctl enable mariadb.service
systemctl start mariadb.service

通过运行mysql_secure_installation脚本来保护数据库服务。

[root@controller ~]# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] 
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] 
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] 
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] 
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] 
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

经过判断,是SELinux引发的问题
解决办法:关闭防火墙

[root@controller ~]# vi /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 two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

再次重启服务报错解决

[root@controller ~]# systemctl enable httpd.service;systemctl start httpd.service

4.配置administrative账号

connection = mysql+pymysql://glance:123456@controller/glance

[keystone_authtoken]

auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = 123456

[paste_deploy]

flavor = keystone

[glance_store]

stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/

3.编辑/etc/glance/glance-registry.conf


[database]

connection = mysql+pymysql://glance:123456@controller/glance

[keystone_authtoken]

auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default

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

安装和配置组件

1.安装软件包

 yum install openstack-nova-api openstack-nova-conductor  openstack-nova-console openstack-nova-novncproxy  openstack-nova-scheduler openstack-nova-placement-api

2.编辑 /etc/nova/nova.conf

[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:123456@controller
my_ip = 10.71.11.12
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
[api_database]

connection = mysql+pymysql://nova:123456@controller/nova_api

[database]

connection = mysql+pymysql://nova:123456@controller/nova

[api]
auth_strategy = keystone

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = 123456

[vnc]
enabled = true
server_listen = $my_ip
server_proxyclient_address = $my_ip

[glance]
api_servers = http://controller:9292

[oslo_concurrency]
lock_path = /var/lib/nova/tmp

[placement]
os_region_name = RegionOne
project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:35357/v3
username = placement
password = 123456

3.由于软件包的一个bug,需要在/etc/httpd/conf.d/00-nova-placement-api.conf文件中添加如下配置

<Directory /usr/bin>
   <IfVersion >= 2.4>
      Require all granted
   </IfVersion>
   <IfVersion < 2.4>
      Order allow,deny
      Allow from all
   </IfVersion>
</Directory>

4.重新http服务

systemctl restart httpd

5.同步nova-api数据库

 su -s /bin/sh -c "nova-manage api_db sync" nova

同步数据库报错


[root@controller ~]# su -s /bin/sh -c "nova-manage api_db sync" nova
Traceback (most recent call last):
  File "/usr/bin/nova-manage", line 10, in <module>
    sys.exit(main())

安装和配置Cinder节点

本节介绍如何为Block Storage服务安装和配置存储节点。 为简单起见,此配置使用空的本地块存储设备引用一个存储节点。

该服务使用LVM驱动程序在该设备上配置逻辑卷,并通过iSCSI传输将其提供给实例。 您可以按照这些说明进行小的修改,以便使用其他存储节点水平扩展您的环境。

1.安装支持的软件包

安装LVM

yum install lvm2 device-mapper-persistent-data

设置LVM服务开机启动

systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service

2.创建LVM物理逻辑卷/dev/sdb

[root@cinder ~]# pvcreate /dev/sdb1
Device /dev/sdb not found (or ignored by filtering).

解决方案:

编辑 vim /etc/lvm/lvm.conf,找到global_filter一行,配置如下

   global_filter = [ "a|.*/|","a|sdb1|"]

之后再执行pvcreate命令,问题解决。

[root@cinder ~]# pvcreate /dev/sdb1
Physical volume "/dev/sdb1" successfully created.

3.创建cinder-volumes逻辑卷组

[root@cinder ~]# vgcreate cinder-volumes /dev/sdb1
Volume group "cinder-volumes" successfully created

4.安装和配置组件
安装软件包

yum install openstack-cinder targetcli python-keystone -y

编辑/etc/cinder/cinder.conf


[DEFAULT]

transport_url = rabbit://openstack:123456@controller
auth_strategy = keystone
my_ip = 10.71.11.14
enabled_backends = lvm
glance_api_servers = http://controller:9292

[database]

connection = mysql+pymysql://cinder:123456@controller/cinder

[keystone_authtoken]

auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = 123456

在[lvm]部分中,使用LVM驱动程序,cinder-volumes卷组,iSCSI协议和相应的iSCSI服务配置LVM后端。 如果[lvm]部分不存在,请创建它:

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

[oslo_concurrency]

lock_path = /var/lib/cinder/tmp

设置存储服务开机启动

systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service

五、登录Dashboard界面

社区Queens Web界面显示三个角色

  • 项目
  • 管理员
  • 身份管理

--share 允许所有项目使用虚拟网络
--external 定义外接虚拟网络 如果需要创建外网使用 --internal
--provider-physical-network provider && --provider-network-type flat 连接flat 虚拟网络

2.创建子网

openstack subnet create --network provider  --allocation-pool start=10.71.11.50,end=10.71.11.60 --dns-nameserver 114.114.114.114 --gateway 10.71.11.254 --subnet-range 10.71.11.0/24 provider
