基于openstack安装部署私有云教程

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。

  1. 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。
  2. 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。
  3. 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。
  4. 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。
  5. 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。
  6. 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。
  7. 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)

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。

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。

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。

# service mysqld start

# chkconfig mysqld on

# mysql_install_db

# mysql_secure_installation

赋权,使其可以远程登录。

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

yum install qpid-cpp-server

启动服务

service qpidd start

chkconfig qpidd on

权限认证服务(keystone)

安装权限认证服务:

yum install openstack-keystone python-keystoneclient -y

创建用户,写入到配置文件中:

openstack-config --set /etc/keystone/keystone.conf \

database connection mysql://keystone:KEYSTONE_DBPASS@controller/keystone

创建keystone数据库表:

$ 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:

su -s /bin/sh -c "keystone-manage db_sync" keystone

设置用户环境变量:

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:

service openstack-keystone start

chkconfig openstack-keystone on

将admin_token设置到环境变量中去。

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-create --name=admin --pass=ADMIN_PASS --email=ADMIN_EMAIL

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

| Property | Value |

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

| email | ADMIN_EMAIL|

| enabled | True |

|id| 332f5ecb18c64bf687b154facd629fb6 |

| name | admin |

| username | admin |

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

[root@controller keystone]# keystone role-create --name=admin

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

| Property | Value |

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

|id| ab5da2c50d7443efb0514e84c2b4adb7 |

| name | admin |

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

[root@controller keystone]# keystone tenant-create --name=admin --description="Admin Tenant"

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

| Property | Value |

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

| description | Admin Tenant |

| enabled | True |

| id | b89723a38b154eeea6416a83b293b0ad |

| name| admin |

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

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

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

[root@controller keystone]#

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 service-create --name=keystone --type=identity \

> --description="OpenStack Identity"

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

| Property | Value |

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

| description |OpenStack Identity|

| enabled | True |

| id | 4bfd5f39b86c45edb92d5c0488987dd8 |

| name| keystone |

| type| identity |

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

[root@controller keystone]# keystone endpoint-create \

> --service-id=$(keystone service-list | awk '/ identity / {print $2}') \

> --publicurl=http://controller:5000/v2.0 \

> --internalurl=http://controller:5000/v2.0 \

> --adminurl=http://controller:35357/v2.0

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

| Property | Value |

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

| adminurl | http://controller:35357/v2.0 |

| id | 0350b72901a141498fe48304b13a1b98 |

| internalurl | http://controller:5000/v2.0|

| publicurl | http://controller:5000/v2.0|

|region |regionOne |

| service_id | 4bfd5f39b86c45edb92d5c0488987dd8 |

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

[root@controller keystone]# keystone user-create --name=demo --pass=DEMO_PASS --email=DEMO_EMAIL

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

| Property | Value |

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

| email |DEMO_EMAIL|

| enabled | True |

|id| b44a9a1462d74f4e928b3b339289a2ae |

| name | demo |

| username | demo |

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

[root@controller keystone]# keystone tenant-create --name=demo --description="Demo Tenant"

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

| Property | Value |

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

| description | Demo Tenant|

| enabled | True |

| id | 7bd79509ee184a2098ca0644679b60a8 |

| name| demo |

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

[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:

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:

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:

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/

http://files.jb51.net/file_images/article/201702/201702040838512.png

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:

$ 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:

su -s /bin/sh -c "glance-manage db_sync" glance

在keystone上创建用户:

keystone user-create --name=glance --pass=GLANCE_PASS --email=glance@example.com

$ keystone user-role-add --user=glance --tenant=service --role=admin

配置授权服务:

openstack-config --set /etc/glance/glance-api.conf keystone_authtoken \

auth_uri http://controller:5000

openstack-config --set /etc/glance/glance-api.conf keystone_authtoken \

auth_host controller

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken \

auth_port 35357

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken \

auth_protocol http

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken \

admin_tenant_name service

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken \

admin_user glance

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken \

admin_password GLANCE_PASS

openstack-config --set /etc/glance/glance-registry.conf paste_deploy \

flavor keystone

启动服务:

service openstack-glance-api start

# service openstack-glance-registry start

# chkconfig openstack-glance-api on

# chkconfig openstack-glance-registry on

创建服务:

$ keystone service-create --name=glance --type=image \

--description="OpenStack Image Service"

$ keystone endpoint-create \

--service-id=$(keystone service-list | awk '/ image / {print $2}') \

--publicurl=http://controller:9292 \

--internalurl=http://controller:9292 \

--adminurl=http://controller:9292

[root@controller ~]# keystone service-create --name=glance --type=image \

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:

复制代码 代码如下:

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

http://files.jb51.net/file_images/article/201702/201702040838513.png

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。

服务器管理(Nova)

对于虚拟机管理我们需要从controller和computer01进行配置。

先来看controller的配置:

yum install openstack-nova-api openstack-nova-cert openstack-nova-conductor \

openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler \

python-novaclient

$ mysql -u root -p

mysql> CREATE DATABASE nova;

mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \

IDENTIFIED BY 'NOVA_DBPASS';

mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \

IDENTIFIED BY 'NOVA_DBPASS';

openstack-config --set /etc/nova/nova.conf database connection mysql://nova:NOVA_DBPASS@controller/nova

openstack-config --set /etc/nova/nova.conf DEFAULT rpc_backend qpid

openstack-config --set /etc/nova/nova.conf DEFAULT qpid_hostname controller

openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 192.168.44.147

openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_listen 192.168.216.210

openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_proxyclient_address 192.168.44.147

openstack-config --set /etc/nova/nova.conf DEFAULT auth_strategy keystone

openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_uri http://controller:5000

openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_host controller

openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_protocol http

openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_port 35357

openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_user nova

openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_tenant_name service

openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_password NOVA_PASS

$ keystone user-create --name=nova --pass=NOVA_PASS --email=nova@example.com

$ keystone user-role-add --user=nova --tenant=service --role=admin

$ keystone service-create --name=nova --type=compute \

--description="OpenStack Compute"

$ keystone endpoint-create \

--service-id=$(keystone service-list | awk '/ compute / {print $2}') \

--publicurl=http://controller:8774/v2/%\(tenant_id\)s \

--internalurl=http://controller:8774/v2/%\(tenant_id\)s \

--adminurl=http://controller:8774/v2/%\(tenant_id\)s

然后是computer01的配置:

yum install openstack-nova-compute

openstack-config --set /etc/nova/nova.conf database connection mysql://nova:NOVA_DBPASS@controller/nova

openstack-config --set /etc/nova/nova.conf DEFAULT auth_strategy keystone

openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_uri http://controller:5000

openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_host controller

openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_protocol http

openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_port 35357

openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_user nova

openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_tenant_name service

openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_password NOVA_PASS

openstack-config --set /etc/nova/nova.conf DEFAULT rpc_backend qpid

openstack-config --set /etc/nova/nova.conf DEFAULT qpid_hostname controller

openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 192.168.44.148

openstack-config --set /etc/nova/nova.conf DEFAULT vnc_enabled True

openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_listen 0.0.0.0

openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_proxyclient_address 192.168.44.148

openstack-config --set /etc/nova/nova.conf DEFAULT novncproxy_base_url http://controller:6080/vnc_auto.html

openstack-config --set /etc/nova/nova.conf DEFAULT glance_host controller

openstack-config --set /etc/nova/nova.conf libvirt virt_type kvm

启动服务:

service libvirtd start

service messagebus start

service openstack-nova-compute start

chkconfig libvirtd on

chkconfig messagebus on

chkconfig openstack-nova-compute on

网络服务配置

在controller端:

openstack-config --set /etc/nova/nova.conf DEFAULT \

network_api_class nova.network.api.API

openstack-config --set /etc/nova/nova.conf DEFAULT \

security_group_api nova

在computer01端:

yum install openstack-nova-network openstack-nova-api

# openstack-config --set /etc/nova/nova.conf DEFAULT \

network_api_class nova.network.api.API

# openstack-config --set /etc/nova/nova.conf DEFAULT \

security_group_api nova

# openstack-config --set /etc/nova/nova.conf DEFAULT \

network_manager nova.network.manager.FlatDHCPManager

# openstack-config --set /etc/nova/nova.conf DEFAULT \

firewall_driver nova.virt.libvirt.firewall.IptablesFirewallDriver

# openstack-config --set /etc/nova/nova.conf DEFAULT \

network_size 254

# openstack-config --set /etc/nova/nova.conf DEFAULT \

allow_same_net_traffic False

# openstack-config --set /etc/nova/nova.conf DEFAULT \

multi_host True

# openstack-config --set /etc/nova/nova.conf DEFAULT \

send_arp_for_ha True

# 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 \

flat_interface eth1

# 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:

http://files.jb51.net/file_images/article/201702/201702040838514.png

创建虚拟机

1、配置ssh密码登录:

ssh-keygen

2、增加公钥到openstack环境中:

nova keypair-add --pub-key ~/.ssh/id_rsa.pub demo-key

3、验证是否配置成功:

nova keypair-list

nova flavor-list

4、创建实例:

复制代码 代码如下:

nova boot --flavor m1.tiny --image cirros-0.3.2-x86_64 --nic netid=DEMO_NET_ID\
--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:

  1. nova boot --flavor m1.tiny --image cirros-0.3.2-x86_64 --nic net-id=55fc305f-570f-4d4f-89d0-ce303e589f20 \
  2. --security-group default --key-name demo-key tfjt

5、使用nova list进行查看。

http://files.jb51.net/file_images/article/201702/201702040838515.png

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

nova-manage floating create --ip_range=192.168.44.16/28

查看可用地址

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。

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:

nova get-vnc-console tfjt novnc

http://files.jb51.net/file_images/article/201702/201702040838516.png

8、我们可以在浏览器中进行访问。

http://files.jb51.net/file_images/article/201702/201702040838517.png

到这里为止,我们的云服务器就算完成了。可以在浏览器上访问我们的云服务器,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。

ALLOWED_HOSTS = ['*']

CACHES = {

'default': {

'BACKEND' : 'django.core.cache.backends.memcached.MemcachedCache',

'LOCATION' : '127.0.0.1:11211'

}

}

OPENSTACK_HOST = "controller"

3、连接

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。

http://192.168.44.147/dashboard/project/

http://files.jb51.net/file_images/article/201702/201702040838518.png

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。

http://files.jb51.net/file_images/article/201702/201702040838529.png

在这里可以看到我们的云服务器实例。

http://files.jb51.net/file_images/article/201702/2017020408385210.png

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:

# su -s /bin/sh -c "cinder-manage db sync" cinder

创建用户并赋予角色:
