[root@controller ~]
# vim /etc/mongod.conf
bind_ip = 10.0.0.11
smallfiles =
true
systemctl
enable

...
|
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

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

yum

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

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
|
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

|
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）：
|
1

|
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
[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
|
1
|
unset
OS_TOKEN OS_URL
|

/v3
--os-project-domain-name default --os-user-domain-name default --os-project-name demo --os-username demo token issue
