本文主要分享的是云计算、openstack的使用、私有云平台建设、云服务器云硬盘的构建和使用。从基本概念入手到私有云建设,信息量非常大。对于openstack的安装部署都是从官方文档中一步步的介绍,内容非常详细。
一、云计算 基本概念
云计算(cloud computing)是基于互联网的相关服务的增加、使用和交付模式,通常涉及通过互联网来提供动态易扩展且经常是虚拟化的资源。云是网络、互联网的一种比喻说法。过去在图中往往用云来表示电信网,后来也用来表示互联网和底层基础设施的抽象。因此,云计算甚至可以让你体验每秒10万亿次的运算能力,拥有这么强大的计算能力可以模拟核爆炸、预测气候变化和市场发展趋势。用户通过电脑、笔记本、手机等方式接入数据中心,按自己的需求进行运算。
云计算分类
简单来说,就是把应用程序和数据都放在由大量服务器组成的云中,用户需要什么只要购买相应服务并使用即可。
云计算分为私有云、公有云、混合云。
云计算的服务分类:基础设施即服务、平台即服务、软件即服务。
- 超大规模。“云”具有相当的规模,google云计算已经拥有100多万台服务器,亚马逊、ibm、微软和yahoo等公司的“云”均拥有几十万台服务器。“云”能赋予用户前所未有的计算能力。
- 虚拟化。云计算支持用户在任意位置使用各种终端获取服务。所请求的资源来自“云”,而不是固定的有形的实体。应用在“云”中某处运行,但实际上用户无需了解应用运行的具体位置,只需要一台笔记本或一个pda,就可以通过网络服务来获取各种能力超强的服务。
- 高可靠性。“云”使用了数据多副本容错、计算节点同构可互换等措施来保障服务的高可靠性,使用云计算比使用本地计算机更加可靠。
- 通用性。云计算不针对特定的应用,在“云”的支撑下可以构造出于变万化的应用,同一片“云”可以同时支撑不同的应用运行。
- 高可伸缩性。“云”的规模可以动态伸缩,满足应用和用户规模增长的需要。
- 按需服务。“云”是一个庞大的资源池,用户按需购买,像自来水、电和煤气那样计费。
- 极其廉价。“云”的特殊容错措施使得可以采用极其廉价的节点来构成云;“云”的自动化管理使数据中心管理成本大幅降低;“云”的公用性和通用性使资源的利用率大幅提升;“云”设施可以建在电力资源丰富的地区,从而大幅降低能源成本。
二、openstack基本概念
openstack是一个开源的云计算管理平台项目,由几个主要的组件组合起来完成
具体工作。openstack支持几乎所有类型的云环境,项目目标是提供实施简单、
可大规模扩展、丰富、标准统一的云计算管理平台。openstack通过各种互补的
服务提供了基础设施即服务(iaas)的解决方案,每个服务提供api以进行集成。
常见组件:
- dashboard(web项目)
- keystone(权限管理)
- nova(管理虚拟机)
- nova-network(管理网络流量和ip)
- glance(镜像管理项目)
- cinder(磁盘管理)
- swift(网盘,对象)
基础的系统图
openstack安装部署
下面来说一说openstack的安装部署。首先说明openstack的整体安装非常复杂,文末提供官方安装文档下载,我就是根据这个英文的官方文档来安装部署的。以下内容是参照官方文档“openstack-install-guide-yum-icehouse.pdf”来的。
首先需要准备3台linux的机器。我这里选用的是centos6.6的64位的系统。配置ip地址,关闭防火墙,修改主机名。
• controller node: 1 processor, 2 gb memory, and 5 gb storage
• compute01: 1 processor, 512 mb memory, and 5 gb storage
• compute02 node: 1 processor, 2 gb memory, and 10 gb storage
我这里controller的ip地址是:192.168.44.147
computer01:192.168.44.148
computer02:192.168.44.149
基本环境配置
以下内容是在controller机器上配置的。
1、数据库安装。
因为需要一个数据库,所以这里选用了mysql数据库。
1
|
yum install mysql mysql-server mysql-python
|
编辑/etc/my.cnf文件,在里面添加如下内容,主要意思就是设置编码为utf-8。
1
2
3
4
5
|
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect = 'set names utf8'
character- set -server = utf8
|
然后启动服务,开机启动。
1
2
3
4
|
# service mysqld start
# chkconfig mysqld on
# mysql_install_db
# mysql_secure_installation
|
赋权,使其可以远程登录。
1
|
grant all privileges on *.* to 'root' @ '%' identified by 'a' ;
|
2、openstack基本包安装。

|
# yum install yum-plugin-priorities
# yum install http://repos.fedorapeople.org/repos/openstack/openstackicehouse/rdo-release-icehouse-3.noarch.rpm
# yum install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.
noarch.rpm
# yum install openstack-utils
# yum install openstack-selinux
|
3、安装消息队列
1
|
yum install qpid-cpp-server
|
启动服务
1
2
|
service qpidd start
chkconfig qpidd on
|
权限认证服务(keystone)
安装权限认证服务:
1
|
yum install openstack-keystone python-keystoneclient -y
|
创建用户,写入到配置文件中:
1
2
|
openstack-config -- set /etc/keystone/keystone .conf \
database connection mysql: //keystone :keystone_dbpass@controller /keystone
|
创建keystone数据库表:
1
2
3
4
5
6
7
|
$ mysql -u root -p
mysql> create database keystone;
mysql> grant all privileges on keystone.* to 'keystone' @ 'localhost' \
identified by 'keystone_dbpass' ;
mysql> grant all privileges on keystone.* to 'keystone' @ '%' \
identified by 'keystone_dbpass' ;
mysql> exit
|
自动生成表:
1
|
su -s /bin/sh -c "keystone-manage db_sync" keystone
|
设置用户环境变量:
1
2
3
4
5
6
7
8
|
admin_token=$(openssl rand -hex 10)
echo $admin_token
openstack-config -- set /etc/keystone/keystone .conf default \
admin_token $admin_token
# keystone-manage pki_setup --keystone-user keystone --keystone-group keystone
# chown -r keystone:keystone /etc/keystone/ssl
# chmod -r o-rwx /etc/keystone/ssl
|
启动keystone服务:
1
2
|
service openstack-keystone start
chkconfig openstack-keystone on
|
将admin_token设置到环境变量中去。
1
2
|
export os_service_token=$admin_token
export os_service_endpoint=http: //controller :35357 /v2 .0
|
创建管理员用户,默认的用户名为admin,密码为admin_pass,你可以自定义修改:

[root@controller keystone] # keystone user-role-add --user=admin --role=_member_ --tenant=admin

|
创建一个权限认证服务,因为我这里的主机名是controller,所以下面有 http://controller:35357/v2.0 这些信息,可以自定义修改:

[root@controller keystone] # keystone user-role-add --user=demo --role=_member_ --tenant=demo
[root@controller keystone] #
|
为了方便我们取到token,我们可以vi admin-openrc.sh,然后添加如下内容:
1
2
3
4
|
export os_username=admin
export os_password=admin_pass
export os_tenant_name=admin
export os_auth_url=http: //controller :35357 /v2 .0
|
在每次关机重启之后都要重新执行下面的命令,让环境变量起作用。否则会报”expecting an auth url via either –os-auth-url or env[os_auth_url]”的错误:
1
|
source admin-openrc.sh
|
我们可以使用下面的命令查看keystone目前的用户有哪些:
1
|
keystone user-list
|
测试效果:
打开restclient-ui-3.5-jar-with-dependencies.jar来测试效果:
url地址是: http://192.168.44.147:5000/v2.0/
访问成功。
配置镜像服务(glance)
在controller服务器中安装服务:

|
yum install openstack-glance python-glanceclient
openstack-config -- set /etc/glance/glance-api .conf database \
connection mysql: //glance :glance_dbpass@controller /glance
openstack-config -- set /etc/glance/glance-registry .conf database \
connection mysql: //glance :glance_dbpass@controller /glance
|
在mysql数据库中创建glance数据库:
1
2
3
4
5
6
7
8
|
$ mysql -u root -p
mysql> create database glance;
mysql> grant all privileges on glance.* to 'glance' @ 'localhost' \
identified by 'glance_dbpass' ;
mysql> grant all privileges on glance.* to 'glance' @ '%' \
identified by 'glance_dbpass' ;
flush privileges;
|
自动生成表:
1
|
su -s /bin/sh -c "glance-manage db_sync" glance
|
在keystone上创建用户:
1
2
|
keystone user-create --name=glance --pass=glance_pass --email=glance@example.com
$ keystone user-role-add --user=glance --tenant=service --role=admin

创建镜像,先将下载好的cirros-0.3.2-x86_64-disk.img放置在/root目录下,然后执行下面的命令:
glance image-create --name "cirros-0.3.2-x86_64" --disk-format qcow2 \
--container-format bare --is-public true --progress < cirros-0.3.2-x86_64-disk.img
查看镜像列表:

glance image-list

在前面我们已经对kvm虚拟化有所了解,所以我们现在知道qcow2就是一个镜像文件。

# openstack-config --set /etc/nova/nova.conf default \
share_dhcp_address true
# openstack-config --set /etc/nova/nova.conf default \
force_dhcp_release true
# openstack-config --set /etc/nova/nova.conf default \
flat_network_bridge br100
# openstack-config --set /etc/nova/nova.conf default \

public_interface eth0
|
nova network-create demo-net –bridge br100 –multi-host t \
–fixed-range-v4 88.8.8.16/28
然后使用nova net-list来查看:
创建虚拟机
1、配置ssh密码登录:
1
|
ssh -keygen
|
2、增加公钥到openstack环境中:
1
|
nova keypair-add --pub-key ~/. ssh /id_rsa .pub demo-key
|
3、验证是否配置成功:
1
2
3
|
nova keypair-list
nova flavor-list
|
4、创建实例:
--security-group default --key-name demo-key demo-instance1
说明:
demo_net_id:指的是nova net-list的id。
demo-instance1指的是虚拟机的名字。
例如我的成功执行如下:
nova boot --flavor m1.tiny --image cirros-0.3.2-x86_64 --nic net-id=55fc305f-570f-4d4f-89d0-ce303e589f20 \ --security-group default --key-name demo-key tfjt
5、使用nova list进行查看。
从这里我们看到我这上面有一个ip地址192.168.44.17.这个地址就是浮动ip。
6、配置浮动ip
浮动ip
1
|
nova-manage floating create --ip_range=192.168.44.16 /28
|
查看可用地址
1
|
nova-manage floating list
|
nova floating-ip-create
给创建的虚拟机绑定浮动ip,这个7bc0086…就是我之前创建的虚拟机的id。后面接上ip地址即可。
1
|
nova add-floating-ip 7bc00086-1870-4367-9f05-666d5067ccff 192.168.44.17
|
监听
cpdump -n -i eth0 icmp
在controller上:
nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
7、使用下面的命令可以输出一个url地址:
1
|
nova get-vnc-console tfjt novnc
|
8、我们可以在浏览器中进行访问。
到这里为止,我们的云服务器就算完成了。可以在浏览器*问我们的云服务器,怎么样是不是很激动。
界面服务(dashboard)
上面我们可以看到很多操作是在终端进行的,那么肯定是有界面版的,所以我们在computer02中进行配置。
1、安装服务
yum install memcached python-memcached mod_wsgi openstack-dashboard
2、文件配置。
在controller中
配置/etc/openstack-dashboard/local_settings。修改为如下内容。
1
2
3
4
5
6

allowed_hosts = ['*']
caches = {
'default': {
'backend' : 'django.core.cache.backends.memcached.memcachedcache',
'location' : '127.0.0.1:11211'
}
}
openstack_host = "controller"
|
3、连接
1

3
4
5
6
|
setsebool -p httpd_can_network_connect on
service httpd start
# service memcached start
# chkconfig httpd on
# chkconfig memcached on
|
4、浏览器中访问。
1
|
http: //192 .168.44.147 /dashboard/project/
|
用户名就是我们之前配置的admin,密码是admin_pass
在这个界面版里面的各种操作我这里就不细说了,可以自己去体验。
在这里可以看到我们的云服务器实例。
云硬盘服务(cinder)
了解过阿里云或者腾讯云的就知道,里面都有一个云硬盘服务,可以给我们的机器增加磁盘。
在controller端:

|
yum stall openstack-cinde
openstack-config -- set /etc/cinder/cinder .conf \
database connection mysql: //cinder :cinder_dbpass@controller /cinder
mysql> create database cinder;
mysql> grant all privileges on cinder.* to 'cinder' @ 'localhost' \
identified by 'cinder_dbpass' ;
mysql> grant all privileges on cinder.* to 'cinder' @ '%' \
identified by 'cinder_dbpass' ;
|
创建数据库表:
1
|
# su -s /bin/sh -c "cinder-manage db sync" cinder
|
创建用户并赋予角色:
1
2
|
$ keystone user-create --name=cinder --pass=cinder_pass--email=cinder@example.com
$ keystone user-role-add --user=cinder --tenant=service --role=admin

总结:整个操作流程非常复杂,我也是花了几天才慢慢搭建好的,这其实也就是个基础,给的其实是一个思路,后面需要怎样的扩展可以根据自己的业务需要进行不同的设置。对于不明白的地方可以查阅官方文档。
