附录一 OpenStack概念、部署、与高级网络应用

首先在这里我会使用RDO快速部署一个具有基本功能的OpenStack环境,如果你想要更完整的部署(比如Heat、Trove组件),可以参考 官方文档

也可以使用Mirantis来进行快速部署,参考 Mirantis ;StackOps部署,参考 StackOps

如果不想安装任何东西,只是在线使用的话,可以访问 http://trystack.org/

要学习更多关于OpenStack的内容,可以参考 陈沙克的日志

API使用请参考http://developer.openstack.org/api-ref.html 以及 http://docs.openstack.org/developer/openstack-projects.html

关于在centos/ubuntu/debian上部署OpenStack请参考 Server-World ,这个更新较为及时。

笔者最近仿照Mirantis撸了一个脚本,全自动安装部署OpenStack,打算再写个Django拖拽安装。当然,要配上kubernestes部署了。请参考 https://github.com/lofyer/openstack-pxe-deployment

OpenStack 部署

在开始之前需要将这些关键组件关系理清。

  • nova:提供compute服务,即保证虚拟机运行的必须服务之一,虚拟机运行于所有提供compute服务的主机之上。
  • neutron:提供network服务,同时提供Open vSwitch、L3、DHCP代理服务。
  • cinder:提供块存储服务,可配合swift使用。
  • swift:提供对象存储服务,目录与文件皆视为对象,外部可以方便取用。
  • glance:提供镜像管理服务。
  • ceilometer:主要功能是监测、收集用户对资源的使用情况,以方便计费、报警等。
  • heat:orchestration模块驱动服务,即从模板根据需求更改配置创建新虚拟机。
  • keystone:身份认证服务。
  • trove:数据库服务。
  • sahara:Hadoop模块。
  • ironic:提供从模板创建新应用程序。

Mirantis Fuel 部署

现在国内使用Mirantis部署的人已经越来越多了,而我们同样使用它来一次快速部署。精通了Mirantis就掌握了大规模集群的部署方式,不只是OpenStack。

RDO 快速部署

使用 RDO 来部署OpenStack。

安装说明

在一台安装有RedHat系列(CentOS)系统上部署,将selinux置为permissive;禁用NetworkManager,启用network服务,详细配置请参考以前章节。

如果安装失败,请查看你的CentOS或者Fedora是否为最新发行版。笔者在写时使用的是CentOS6,目前为CentOS7。

# yum install -y http://rdo.fedorapeople.org/rdo-release.rpm
# yum install -y epel-release
# yum update -y
# yum install -y openstack-packstack
# packstack --allinone

请耐心等待,以上过程预计花费一到两小时。有关此次部署的详细信息,在安装完成后可以看到:

**** Installation completed successfully ******

Additional information:
* A new answerfile was created in: /root/packstack-answers-20140730-110621.txt
* Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
* File /root/keystonerc_admin has been created on OpenStack client host 192.168.2.160. To use the command line tools you need to source the file.
* To access the OpenStack Dashboard browse to http://192.168.2.160/dashboard .
Please, find your login credentials stored in the keystonerc_admin in your home directory.
* To use Nagios, browse to http://192.168.2.160/nagios username: nagiosadmin, password: ea65dc070f034776
* Because of the kernel update the host 192.168.2.160 requires reboot.
* The installation log file is available at: /var/tmp/packstack/20140730-110621-upxlZJ/openstack-setup.log
* The generated manifests are available at: /var/tmp/packstack/20140730-110621-upxlZJ/manifests

可修改 /root/packstack-answers-20140730-110621.txt 内容以 增加计算节点 ;同理可增加网络节点(待实验)。

:::{note}

假如更换了admin/demo/services的密码,不要忘记在此配置文件中将其修改为新密码。

添加计算节点

使用Neutron网络

分步详细部署

CentOS 7以及Ubuntu等发行版部署OpenStack的过程基本一致,在此以CentOS 7示例。

机器准备

控制节点:controller0(192.168.77.50)

计算节点:controller0(192.168.77.50),compute0(192.168.77.51)

网络节点:neutron0(192.168.77.30)

存储节点:cinder0(192.168.77.60),swift0(192.168.77.70),swift-stor0(192.168.77.71),swift-stor1(192.168.77.72),swift-stor2(192.168.77.73)

Heat节点:heat0(192.168.77.80)

每台机器首先将selinux设置为permissive或者disable、打开ssh服务、禁用防火墙(可安装iptables-services服务,关闭firewalld,iptables -F后再service iptables save)、关闭NetworkManager服务、打开network服务并配置IP。

:::{note}

bash_rc文件用例

bash_rc文件比如os_bootstrap、admin_keystone,其中os_bootstrap用于创建基本keystone服务使用,admin_keystone为创建的admin用户。

:::

:::{note}

认证服务

OpenStack中的keystone服务负责绝大部分authentication的工作,其中属于service组的用户(nova、glance)也是基于keystone认证的,所以不要认为service中的服务仅仅是一个服务而已。

export OS_TENANT_NAME=admin
export OS_AUTH_URL=http://localhost:35357/v2.0/

初始化控制节点

在控制节点controller0,配置源、数据库、RabbitMQ、Memcached。

/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

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.

      # 设置mysql的root密码
      Set root password? [Y/n] y
      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
    Remove anonymous users? [Y/n] y
     ... 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
  Disallow root login remotely? [Y/n] y
   ... 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
Remove test database and access to it? [Y/n] y
 - 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
     Reload privilege tables now? [Y/n] y
      ... 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!

[root@neutron0 ~]# ovs-vsctl add-br br-ext
# eno50332208对应eth2

[root@neutron0 ~]# vi /etc/neutron/l3_agent.ini
# line 63
external_network_bridge = br-ext
[root@neutron0 ~]# systemctl restart neutron-l3-agent

在任意节点修改(neutron的配置属于集群全局配置,此处在控制节点修改,其他节点也可):

使用示例

基本操作

一些常用操作。

添加镜像

以admin或者demo用户身份登录dashboard后,选择“镜像”,上传ISO。

```{image} ../images/apx01-01.png :align: center

#### 从ISO安装新实例

在“实例”选项卡中,选择“添加实例”,并从现有镜像启动。

```{image} ../images/apx01-02.png
:align: center

与owncloud集成

  1. 创建一个指定region的endpoint于swift服务中

```{code}

source ./keystone_admin

# keystone endpoint-create --service swift --region swift_region \ --publicurl "http://192.168.2.160:8080/v1/AUTH_7d11dd5a3f3544149e8b6a9799a2aa48/oc"

```

其中的publicurl可以从container的详细信息中查看。

  1. 使用owncloud的第三方app——external storage,如下进行填写
  • 目录名称:显示在owncloud中的目录名称。
  • user:project用户名。
  • bucket:容器名。
  • region:上一步指定的region。
  • key:用户密码。
  • tenant:project名。
  • password:用户密码。
  • service_name:服务名,即swift。
  • url:使用keystone认证的url,即http://192.168.2.160:5000/v2.0 。
  • timeout:超时时长,可不填。

oVirt使用Glance与Neutron服务

oVirt自3.3版本起,便可以添加外部组件,比如Foreman、OpenStack的网络或镜像服务。

在添加OpenStack相关组件之前,oVirt管理端需要配置OpenStack的KeyStone URL:

1
2
# engine-config --set KeystoneAuthUrl=http://192.168.2.160:35357/v2.0
# service ovirt-engine restart

添加OpenStack镜像服务Glance至oVirt

  1. 在OpenStack的控制台中,添加一个新镜像,比如my_test_image,格式为raw。

```{image} ../images/apx01-03.png :align: center

1
2
3
4
2. 在oVirt左边栏,选择External Provider添加OpenStack Image服务。

```{image} ../images/apx01-04.png
:align: center

:::{note}

认证选项

用户名:glance

密码:存于RDO配置文件中,形如 CONFIG_GLANCE_KS_PW=bf83b75a635843b4

Tenant:services

:::

  1. 然后可以在oVirt的存储域中看到刚刚添加的Glance服务。

```{image} ../images/apx01-05.png :align: center

#### Neutron

```{image} ../images/apx01-06.jpeg
:align: center

可参考 NeutronVirtualAppliance 以及 Overlay_Networks_with_Neutron_Integration ,另外提供 操作视频

  1. 配置oVirt。
1
2
3
# engine-config --set OnlyRequiredNetworksMandatoryForVdsSelection=true
# yum install vdsm-hook-openstacknet
# service ovirt-engine restart
  1. 如图添加Neutron组件。

```{image} ../images/apx01-07.png :align: center

2
```{image} ../images/apx01-08.png
:align: center

:::{note}

认证选项

用户名:neutron

密码:存于RDO配置文件中,形如 CONFIG_NEUTRON_KS_PW=a16c52e3ea634324

Tenant:services

agent 配置相同

OpenStack常见问题

Q:如何校验密码是否正确?

A:keystone --os-username=neutron --os-password=servicepassword --os-auth-url=http://localhost:35357/v2.0 token-get

Q:管理界面Swift不能删除目录?

A:使用命令 swift delete public_container aaa/ 进行删除。

Q: Neutron 网络快速开始?

A:参考https://www.ustack.com/blog/neutron_intro/

Q:OpenStack组件间的通信是靠什么?

A:AMQP,比如RabbitMQ、Apache的ActiveMQ,部署时候可以选择,如果对这种消息传输工具有兴趣可以参考 rabbitmq tutorial 以及 各种有用的插件(web监视等)

Q:Swift有什么好用的客户端么?

A:python-swiftclientGladient Cloud DesktopCloudberryCyberduckWebDriveS3 Browser 等。
