[openstack信息简介]
Openstack项目是一个开源的云计算平台,它为广大云平台提供了可大规模扩展的平台,全世界的云计算技术人员创造了这个项目,通过一组相互关联的服务来提供了Iaas基础解决方案,每一个服务都通过提供自身的API来提供服务,个人或者企业完全可以根据自身的需求来安装一部分或者全部的服务。
通过下面一张表格来描述一下当前openstack的各个组件及功能。
Service |
Project name |
Description |
Dashboard |
Horizon |
通过提供了web服务实现openstack服务的交互,比如创建实例,配置IP以及配置访问控制。 |
Compute |
Nova |
在系统环境中管理整个生态圈的计算。承担着经过请求后的孵化,调度和回收虚拟机等一系列的责任,是核心组件,可以说是真正实现的角色。 |
Networking |
Neutron |
提供了网络服务,连接起了其他服务。为用户提供API去定义网络并将它们联系起来。支持多种网络供应商和新兴的网络技术,比如vxlan等。 |
Object Storage |
Swift |
通过了RESTful API来存储和检索任务非结构化的数据对象,对数据同步和横向扩展有很高的容错性,不是挂载文件目录形势的使用方式,它是将对象和文件写入多个驱动程序以确保数据在服务器集群中的完整性。 |
Block |
Cinder |
提供了块存储和持久化,可插拔式的体系架构简化了创建和管理存储设备。 |
Identity |

Orchestration |
Heat |
通过组合模板来进行的服务。 |
Database service |
Trove |
为关系数据库和非关系数据库提供可扩展和可依赖的云数据库服务。 |
Data processing service |
Sahara |
属于openstack的大数据项目。是openstack与hadoop的融合。 |
[openstack体系架构]
下面这张图完整的体现了openstack服务之间的联系(Conceptualarchitecture概念架构):
从这张图稍作了解的话还是能够理解的,其他服务通过相互的写作和工作为中间是VMs提供了各种服务。Keystone提供了验证服务,Ceilometer作为了整个系统的监控,Horizon提供了UI访问界面,这3个服务主要起到了把控全局的作用。在左下角有一个Ironic,它的作用是解决物理机的添加、删除、安装部署等功能,类似为集群自动化增添节点。
可以看说,整个生态系统外围掌控整个系统,内部各个服务相互协作提供各种功能,并且系统伸缩性大,扩展性高。
[openstack环境准备]
软件:vmareworkstation 11
操作系统:CentOS7 3.10.0-327.e17.x86_64
2台:一台作为控制节点controller,一台作为计算节点compute。
基本设置:
1. 每一个都选择2张网卡,一张对外提供服务,需要连接互联网,可以是桥接或者nat模式。一张提供内部网络,作为openstack内部联系的网络,在VMware选择host only模式。
2. 修改对应的主机名,并在hosts做主机与IP的解析,
3. 做时间同步,可以是本地,也可以是时间服务器,在centos7中改为chrony,调整完毕后设置开机启动。
4. 注!:方便起见,把防火墙和selinux全部关闭,确保网络畅通。
到这一步,基本上的环境配置就搞定了,我相信有余力去学习openstack,那对linux有了基本的理解,上述步骤应该能搞定。最后重启系统准备安装。
[openstack基本安装]
在centos上默认包含openstack版本,可以直接用yum安装最新的版本不用费力去寻找相关的源码包。
[[email protected]_2~]# yum install centos-release-openstack-mitaka.noarch -y
安装openstack客户端
[[email protected]_2~]# yum install -y python-openstackclient
openstack自带有openstack-selinux来管理openstack服务之间的安装性能,这里,为了实验顺利,这里选择忽略,实际情况可以根据需求选择是否安装。
注!:如没有特殊说明以下安装说明都是在controller中执行。
[数据库及nosql安装]
[[email protected]~]yum install mariadb mariadb-server python2-PyMySQL
#yum安装数据库,用于到时候创建服务的数据库 port:3306
[[email protected]~]mysql_secure_installation #安全配置向导,包括root密码等。
[[email protected]]# vim openstack.cnf
[mysqld]
......
bind-address= 0.0.0.0 #这个地址表示能够让所有的地址能远程访问。
default-storage-engine= innodb
innodb_file_per_table
max_connections= 4096
collation-server= utf8_general_ci
character-set-server= utf8
#修改配置文件,定义字符集和引擎,其他可按需修改。
这是yum安装的数据库,是mariadb是兼容mysql的,也可以选择源码编译安装,安装过程这里不详细讲了。
MariaDB[(none)]> grant all on *.* to [email protected]‘%‘ identified by "root" ;
这里先添加远程登录的root用户。
[[email protected]]# yum install -y mongodb-server mongodb
安装mongodb数据库,提高web访问的性能。Port:27017
[[email protected]]# vim /etc/mongod.conf
bind_ip = 192.168.10.200 #将IP绑定在控制节点上。
......
[[email protected]]# systemctl enable mongod.service
Createdsymlink from /etc/systemd/system/multi-user.target.wants/mongod.service to/usr/lib/systemd/system/mongod.service.
[[email protected]]# systemctl start mongod.service
设置开机自启动。
[[email protected]]#yum install memcached python-memcached
[[email protected]]# systemctl enable memcached.service
Createdsymlink from /etc/systemd/system/multi-user.target.wants/memcached.service to /usr/lib/systemd/system/memcached.service.
[[email protected]]# systemctl start memcached.service
安装memcached并设置开机启动。Port:11211 memcache用于缓存tokens
[rabbitmq消息队列安装与配置]
为了保持openstack项目松耦合,扁平化架构的特性,因此消息队列在整个架构中扮演了交通枢纽的作用,所以消息队列对openstack来说是必不可少的。不一定适用RabbitMQ,也可以是其他产品。
[[email protected]]# yum install -y rabbitmq-server
[[email protected]]# systemctl enable rabbitmq-server.service
Createdsymlink from/etc/systemd/system/multi-user.target.wants/rabbitmq-server.service to/usr/lib/systemd/system/rabbitmq-server.service.
[[email protected]]# systemctl start rabbitmq-server.service
[[email protected]]# rabbitmqctl add_user openstack openstack
Creatinguser "openstack" ...
[[email protected]]# rabbitmqctl set_permissions openstack ".*" ".*"".*"
Settingpermissions for user "openstack" in vhost "/" ...
#安装rabbidmq,创建用户并设置允许读写操作。
[Identity service—keystone]
接下来是openstack第一个验证服务——keystone服务安装,它为项目管理提供了一系列重要的验证服务和服务目录。openstack的其他服务安装之后都需要再keystone进行验证过,之后能够跟踪所有在局域网内安装好的openstack服务。
安装keystone之前先配置好数据库环境。
[[email protected]~]# mysql -uroot -p
MariaDB[(none)]> CREATE DATABASE keystone;
QueryOK, 1 row affected (0.00 sec)
MariaDB[(none)]> grant all on keystone.* to [email protected] identified by‘keystone‘;
QueryOK, 0 rows affected (0.09 sec)
MariaDB[(none)]> grant all on keystone.* to [email protected]‘%‘ identified by‘keystone‘;
QueryOK, 0 rows affected (0.00 sec)
MariaDB[(none)]> flush privileges;
QueryOK, 0 rows affected (0.05 sec)
#生成admin tokens
[[email protected]~]# openssl rand -hex 10
bc6aec97cc5e93a009b1
安装keystone httpd wsgi
WSGI是Web Server Gateway Interface的缩写,是python定义的web服务器或者框架的一种接口,位于web应用程序和web服务器之间。
[[email protected]~]# yum install -y openstack-keystone httpd mod_wsgi
修改keystone配置文件
[[email protected]~]# vim /etc/keystone/keystone.conf
[default]
[DEFAULT]
...
admin_token= bc6aec97cc5e93a009b1 #这里填之前生成的admintokens
[database]
......
connection= mysql+pymysql://keystone:[email protected]/keystone
[token]
......
provider= fernet #控制tokens验证、建设和撤销的操作方式
[[email protected]~]# sh -c "keystone-manage db_sync" keystone #设置数据库同步
[[email protected]~]# keystone-manage fernet_setup --keystone-user keystone --keystone-groupkeystone #生成fernetkeys
[[email protected]~]# vim /etc/httpd/conf/httpd.conf #修改配置文件
...
ServerAdmincontroller
...
接下来配置虚拟主机
[[email protected]troller~]# vim /etc/httpd/conf.d/wsgi-keystone.conf
WSGIScriptAlias //usr/bin/keystone-wsgi-public
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog/var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
Require all granted
</Directory>
</VirtualHost>
<VirtualHost*:35357>
WSGIDaemonProcess keystone-adminprocesses=5 threads=1 user=keystone group=keystone display-na
me=%{GROUP}
WSGIProcessGroup keystone-admin
WSGIScriptAlias //usr/bin/keystone-wsgi-admin
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog/var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
Require all granted
</Directory>
</VirtualHost>
设置开机自启动。
[[email protected]~]# systemctl enable httpd.service
[[email protected]~]# systemctl start httpd.service
配置上述生成的admin token
[[email protected]~]# export OS_TOKEN=bc6aec97cc5e93a009b1
配置endpoint URL
[[email protected]~]# export OS_URL=http://controller:35357/v3
Identity 版本
[[email protected]~]# export OS_IDENTITY_API_VERSION=3
创建identity service 。
[[email protected]~]# openstack service create --namekeystone --description "OpenStack Identity" identity
验证服务管理着openstack项目中所有服务的API endpoint,服务之间的相互联系取决于验证服务中的API endpoint。根据用户不同,它提供了三种形式的API endpoint,分别是admin、internal、public。admin默认允许管理用户和租户,internal和public不允许管理用户和租户。因为在openstack中一般都会设置为2张网卡,一张对外提供服务,一张是内部交互提供的网络,因此对外一般使用public API 能够使得用户对他们自己的云进行管理。Admin API 一般对管理员提供服务,而internal API 是针对用户对自己所使用opservice服务进行管理。因此一般一个openstack服务都会创建多个API,针对不用的用户提供不同等级的服务。
[[email protected]~]# openstack endpoint create --region RegionOne identity publichttp://controller:5000/v3
[[email protected]~]# openstack endpoint create --region RegionOne identity internalhttp://controller:5000/v3
[[email protected]~]# openstack endpoint create --region RegionOne identity adminhttp://controller:35357/v3
接下来是创建默认的域、工程(租户)、角色、用户以及绑定。
[[email protected]~]# openstack domain create --description "Default Domain" default
[[email protected]~]# openstack project create --domain default \
> --description "Admin Project"admin
[[email protected]~]# openstack user create --domain default --password-prompt admin
UserPassword:
RepeatUser Password:#密码admin
[[email protected]~]# openstack role add --project admin --user admin admin
对demo工程、用户、角色进行绑定。
[[email protected]~]# openstack project create --domain default --description "Service Project" service
[[email protected]~]# openstack project create --domain default \
> --description "Demo Project" demo
[[email protected]~]# openstack user create --domain default --password-prompt demo
UserPassword:
RepeatUser Password: #demo
[[email protected]~]# openstack role add --project demo --user demo user
测试验证服务是否安装有效。
1.在keystone-paste.ini中的这3个字段中删除admin_token_auth
[[email protected]~]# vim /etc/keystone/keystone-paste.ini
[pipeline:public_api]
......admin_token_auth
[pipeline:admin_api]
......
[pipeline:api_v3]
......
2.删除刚才设置的OS_token和OS_URL
Unset OS_TOKEN OS_URL
然后开始验证,没报错说明成功了。
[[email protected]~]# openstack --os-auth-url http://controller:35357/v3 \
> --os-project-domain-name default--os-user-domain-name default \
> --os-project-name admin --os-username admintoken issue
Password:#admin
验证demo用户:
[[email protected]~]# openstack --os-auth-url http://controller:5000/v3 \
> --os-project-domain-name default--os-user-domain-name default \
> --os-project-name demo --os-username demotoken issue
Password:#demo
最后创建user脚本
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
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
这里如果是多个台服务器配置的话。这样的脚本就会方便你配置管理员的API。主要还是起到了方便的作用。
[Image service—glance]
依旧先创建数据库以及相关用户。
[[email protected]~]# mysql -u root -p
MariaDB[(none)]> CREATE DATABASE glance;
QueryOK, 1 row affected (0.04 sec)
MariaDB[(none)]> GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘localhost‘ \
-> IDENTIFIED BY ‘glance‘;
QueryOK, 0 rows affected (0.28 sec)
MariaDB[(none)]> GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘%‘ \
-> IDENTIFIED BY ‘glance‘;
QueryOK, 0 rows affected (0.01 sec)
MariaDB[(none)]> flush privileges;
QueryOK, 0 rows affected (0.08 sec)
[[email protected]~]# . admin-openrc注!如果在其他服务器上就需要执行这个脚本,来配置admin api
接来下创建glance用户以及绑定。
[[email protected]~]# openstack user create --domain default --password-prompt glance
UserPassword:
RepeatUser Password: #glance
将admin 角色增加到 service工程和 glance用户。
[[email protected]~]# openstack role add --project service --user glance admin
[[email protected]~]# openstack service create --name glance \
> --description "OpenStack Image"image
创建image服务的三种接口
[[email protected]~]# openstack endpoint create --region RegionOne \
> image public http://controller:9292
[[email protected]~]# openstack endpoint create --region RegionOne \
> image internal http://controller:9292
[[email protected]~]# openstack endpoint create --region RegionOne image admin http://controller:9292
安装openstack-glance并修改配置文件
[[email protected]~]# yum install -y openstack-glance
[[email protected]~]# vim /etc/glance/glance-api.conf
......

[Network service—neutron ]
Neutron最主要是功能是负责虚拟环境下的网络,但它之前并不叫neutron,是叫quantum,因为被注册然后才改名的。网络在openstack中最复杂的功能,配置也是最繁琐的,从官方文档中单独把网络向导列出来写一大篇文章就可以看出来。从L1到L7都有所涉及,openstack所有的服务都是通过网络练习起来。像glance一样,neutron本身并提供网络服务,它的大部分功能都是通过Plugin提供的,除了DHCP和L3-agent,这些信息在配置服务的过程中能体现出来。
Neutron本身有2种模式,一种是provider networks,指的是运营商提供网络,可以说是外网,还有一种是Self-service networks,这是私人网络,可以说内网,但是第二种网络模式包含第一种,所以基本上都会选择第二种部署方式,对外提供服务用外网,对内使用内网,因此部署openstack一般都会使用2张网卡。
在controller上配置数据库,赋权等操作。

[Dashboard-horizon]
其实将neutron安装完毕以后openstack项目最基本的已经能够运行起来了,但是为了操作更加方便直观,我们再安装WebUI,就是horizon。
[[email protected]~]# yum install -y openstack-dashboard
[[email protected]~]# vim /etc/openstack-dashboard/local_settings
......
OPENSTACK_HOST= "controller"
ALLOWED_HOSTS= [‘*‘,]
OPENSTACK_KEYSTONE_URL= "http://%s:5000/v3.0" % OPENSTACK_HOST
OPENSTACK_API_VERSIONS= {
"identity": 3,
"volume": 2,
"compute": 2,
}
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT= True
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN= "default"
OPENSTACK_KEYSTONE_DEFAULT_ROLE= "user"
TIME_ZONE= "UTC"#时区
SESSION_ENGINE= ‘django.contrib.sessions.backends.cache‘
CACHES= {
‘default‘: {
‘BACKEND‘:‘django.core.cache.backends.memcached.MemcachedCache‘,
‘LOCATION‘: ‘controller:11211‘,
}
}
重启httpd 和memcached服务。
[[email protected]~]# systemctl restart httpd.service
[[email protected]~]# systemctl restart memcached.service
最后打开http://controller/dashboard登录
登录之后能够对openstack进行基本的操作了,当然还有cinder,swift,heat等等组件并没有全部部署上去,这些可以根据需求自行部署。
