OpenStack Mitaka for Ubuntu 16.04 LTS 部署指南
http://docs.openstack.org/mitaka/install-guide-rdo/
官方文档
把上面的Ubuntu 换成Centos,其他详情请看上面的部署指南
4.1配置OpenStack
yum install centos-release-openstack-mitaka 安装OpenStack client: yum install python-openstackclient 安装MariaDB yum install mariadb mariadb-server python2-Pymysql [[email protected] ~]# vim /etc/my.cnf.d/openstack.cnf [mysqld] bind-address = 10.0.0.11 default-storage-engine = innodb innodb_file_per_table max_connections = 4096 collation-server = utf8_general_ci character-set-server = utf8 systemctl enable mariadb.service systemctl start mariadb.service mysql_secure_installation ##设置密码
安装NoSQL数据库(MongoDB)
注:只有计量服务(Telemetry Service)用到
Controller Node
① 安装MongoDB yum install mongodb-server mongodb [[email protected] ~]# vim /etc/mongod.conf bind_ip = 10.0.0.11 smallfiles = true systemctl enable mongod.service systemctl start mongod.service
安装消息队列服务(RabbitMQ)
Controller Node
① 安装RabbitMQ
yum install rabbitmq-server systemctl enable rabbitmq-server.service systemctl start rabbitmq-server.service rabbitmqctl add_user openstack openstack ##密码 Creating user "openstack" ... rabbitmqctl set_permissions openstack ".*" ".*" ".*" ##权限 Setting permissions for user "openstack" in vhost "/" ...
安装Memcached
身份服务(Identity Service)认证机制需要使用Memcached缓存令牌(Token)
Controller Node
① 安装Memcached
yum install memcached python-memcached systemctl enable memcached.service systemctl start memcached.service
4.2 身份服务配置(Identity Service Keystone)
Identity服务采用RESTful设计,使用REST API提供Web服务接口。
注:常见的Web Service 方式有SOAP 、WSDL 、REST 。
部署节点:Controller Node
在MariaDB(MySQL)中创建Keystone数据库
mysql -uroot -p123456 CREATE DATABASE keystone; GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘localhost‘ IDENTIFIED BY ‘keystone‘; GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘%‘ IDENTIFIED BY ‘keystone‘; flush privileges; quit; % 则代表了所有的host都能远程访问该mysql。但MySQL官方文档指出, % 并不包括localhost 。因此需要对localhost 和% 都进行授权。
生成临时管理身份认证令牌(ADMIN_TOKEN)
生成一个随机值,作为keystone初始配置时的ADMIN_TOKEN
openssl rand -hex 10 2d3c132acf773c01838e
安装Keystone和Apache HTTP Server with mod_wsgi
本文采用Apache HTTP server with mod_wsgi 监听端口5000 和35357 提供身份服务。默认keystone 服务已经监听端口5000 和35357 ,为避免冲突,需首先关闭keystone服务
yum install openstack-keystone httpd mod_wsgi vim /etc/keystone/keystone.conf admin_token = ADMIN_TOKEN connection = mysql+pymysql://keystone:[email protected]/keystone provider = fernet #####Fernet令牌提供者 将配置信息写入到身份服务数据库keystone : su -s /bin/sh -c "keystone-manage db_sync" keystone 初始化Fernet keys: keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
vim /etc/httpd/conf/httpd.conf
ServerName controller
vim /etc/httpd/conf.d/wsgi-keystone.conf
Listen 5000Listen 35357
<VirtualHost *:5000>
WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-public
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-admin processes=5 threads=1 user=keystone group=keystone display-name=%{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>
systemctl enable httpd.service systemctl start httpd.service
创建服务实体(Service Entity)和API路径(API Endpoints)
vim admin ##设置环境变量 export OS_TOKEN=2d3c132acf773c01838e export OS_URL=http://controller:35357/v3 export OS_IDENTITY_API_VERSION=3 source admin
创建服务实体
身份服务管理着一个OpenStack的服务目录,通过服务目录确定其他服务是否可用
openstack service create --name keystone --description "OpenStack Identity" identity
创建API路径
OpenStack每个服务可使用三种API路径变体: admin , internal 和public 。默认情况, admin 类型的
API路径可修改用户(user)和租户(tenant),而internal 和public 类型的API路径不允许该操作。
openstack endpoint create --region RegionOne identity public http://controller:5000/v3 openstack endpoint create --region RegionOne identity internal http://controller:5000/v3 openstack endpoint create --region RegionOne identity admin http://controller:35357/v3
创建域(Domain)、计划(Project)、用户(User)、角色(Role):
openstack domain create --description "Default Domain" default openstack project create --domain default --description "Admin Project" admin openstack user create --domain default --password-prompt admin openstack role create admin
创建的任何角色都必须映射到OpenStack配置文件policy.json 指定的角色:
openstack role add --project admin --user admin admin
创建服务计划
openstack project create --domain default --description "Service Project" service
常规(非管理员)的任务应该使用一个普通的项目和用户。
openstack project create --domain default --description "Demo Project" demo openstack user create --domain default --password-prompt demo openstack role create user
将普通用户角色授予示例计划和示例用户:
openstack role add --project demo --user demo user
处于安全考虑,禁用临时身份认证令牌机制
修改文件vi /etc/keystone/keystone‐paste.ini ,从
[pipeline:public_api] 、[pipeline:admin_api] , [pipeline:api_v3] 处移除admin_token_auth 配置信息。
取消环境变量OS_TOKEN 和OS_URL
unset OS_TOKEN OS_URL
为admin 用户申请一个身份认证令牌
openstack ‐‐os‐auth‐url http://controller:35357/v3 ‐‐os‐project‐domain‐name default ‐‐osuser‐domain‐name default ‐‐os‐project‐name admin ‐‐os‐username admin token issue 为demo 用户申请一个身份认证令牌 openstack --os-auth-url http://controller:5000/v3 --os-project-domain-name default --os-user-domain-name default --os-project-name demo --os-username demo token issue
其他申请方法:
创建OpenStack客户端环境脚本方法
vim admin-openrc 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_AUTH_TYPE=password export OS_IDENTITY_API_VERSION=3 export OS_IMAGE_API_VERSION=2 source admin-openrc openstack token issue vim demo-openrc export OS_PROJECT_DOMAIN_NAME=default export OS_USER_DOMAIN_NAME=default export OS_PROJECT_NAME=demo export OS_USERNAME=demo export OS_PASSWORD=demo export OS_AUTH_URL=http://controller:5000/v3 export OS_AUTH_TYPE=password export OS_IDENTITY_API_VERSION=3 export OS_IMAGE_API_VERSION=2 source demo-openrc openstack token issue
4.3 镜像服务配置(Image Service Glance)
用户可使用OpenStack镜像服务提供的REST API 查询、注册、恢复虚拟机镜像。
部署节点:Controller Node
mysql -uroot -p123456 CREATE DATABASE glance; GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘localhost‘ IDENTIFIED BY ‘glance‘; GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘%‘ IDENTIFIED BY ‘glance‘; flush privileges;
. admin-openrc
在OpenStack中创建一个glance用户
openstack user create --domain default --password-prompt glance User Password: glance Repeat User Password:glance
将admin 角色授予glance 用户和service 计划
openstack role add --project service --user glance admin
创建glance服务实体
openstack service create --name glance --description "OpenStack Image" image
创建镜像服务API路径
openstack endpoint create --region RegionOne image public http://controller:9292 openstack endpoint create --region RegionOne image internal http://controller:9292 openstack endpoint create --region RegionOne image admin http://controller:9292
安装和配置Glance服务组件
yum install openstack-glance vim /etc/glance/glance-api.conf
connection = mysql+pymysql://glance:[email protected]/glance
在[keystone_authtoken] 和[paste_deploy] 处,配置身份服务访问。
注:注释掉[keystone_authtoken] 处所有默认内容 M版默认是全注释掉的
[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 = GLANCE_PASS
[paste_deploy]
...
flavor = keystone
在[glance_store]处配置本地文件系统存储和镜像文件存储位置。
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
vim /etc/glance/glance-registry.conf connection = mysql+pymysql://glance:[email protected]/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 = GLANCE_PASS [paste_deploy] flavor = keystone
将配置信息写入glance数据库
su -s /bin/sh -c "glance-manage db_sync" glance
忽略所有有关’弃用’(deprecate)的输出
Option "verbose" from group "DEFAULT" is deprecated for removal. Its value may be silently ignored in the future.
/usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:1056: OsloDBDeprecationWarning: EngineFacade is deprecated; please use oslo_db.sqlalchemy.enginefacade
