yum install centos-release-openstack-mitaka

安装OpenStack client：
yum install python-openstackclient


安装MariaDB
yum install mariadb mariadb-server python2-PyMySQL


# vim /etc/my.cnf.d/openstack.cnf

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 enablemariadb.service
systemctl startmariadb.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
# 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

1
2
3
4
5
6
7
yum install rabbitmq-server
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
rabbitmqctl add_user openstackopenstack ##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

1
2
3
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


1
2
3
4
5
6
7
8
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

1
2
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

1
2
3

9
yum install openstack-keystone httpd mod_wsgi
vim/etc/keystone/keystone.conf
admin_token = ADMIN_TOKEN
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/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>

    <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）

1
2
3
4
5
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

1
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。

1
2
3
openstack endpoint create --region RegionOneidentity public http://controller:5000/v3
openstack endpoint create --region RegionOneidentity 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）：

1
2
3
4
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：

1
openstack role add --project admin --user admin admin





创建服务计划

1
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。

1
2
3
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：

1
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
、 ， 处移除admin_token_auth 配置信息。
取消环境变量OS_TOKEN 和OS_URL

1
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 demotoken issue
