OpenStack(M版)之Keystone组件（安装、配置、创建域，项目，用户，角色等）

进入root权限

进入数据库

$ mysql -u root -p

#创建数据库
>>> CREATE DATABASE keystone;

#赋予数据库权限
# <KEYSTONE_DBPASS>为自定义密码 -建议换成1234 或者其他数字
>>> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY 'KEYSTONE_DBPASS';
>>> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY 'KEYSTONE_DBPASS';


#退出数据库
>>> exit

安装Keystone组件

#禁用Keystone服务在安装完成后自启
$ echo "manual" > /etc/init/keystone.override
# 安装软件包
$ apt-get install keystone apache2 libapache2-mod-wsgi

生成随机值作为临时令牌`token`

$ openssl rand -hex 10

---------
ce3a92ef9d6296a93eb4
--------------会生成一段类似上面的令牌，保存下来

#配置Glance服务
$ vim /etc/keystone/keystone.conf

# 文件内容
[DEFAULT]
#<ADMIN_TOKEN>为生成的随机值
admin_token = ADMIN_TOKEN

[database]
#<KEYSTONE_DBPASS>注意和前面赋予权限一致 （换成密码） 务必把原来的connection注释掉，只能有一个connection
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone

[token]
#大约在1987行 :1987可直接跳转
provider = fernet

# 同步数据库
$ su -s /bin/sh -c "keystone-manage db_sync" keystone

这里同步数据库容易出错，出错后参考：https://www.jianshu.com/p/3a2ce134b786

#初始化Fernet令牌
$ keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

# 配置Apache服务
$ vim /etc/apache2/apache2.conf

# 文件内容，在文件中靠前的位置添加该项
ServerName controller

#配置虚拟主机
$ vim /etc/apache2/sites-available/wsgi-keystone.conf

# 文件内容

#启用虚拟机
ln -s /etc/apache2/sites-available/wsgi-keystone.conf /etc/apache2/sites-enabled

#重启Apache服务
$ service apache2 restart

# 删除默认的SQLite数据库
$ rm -f /var/lib/keystone/keystone.db

#创建服务实体和API访问端点
#配置身份认证令牌`token`
# <ADMIN_TOKEN>为生成的随机值
$ export OS_TOKEN=ADMIN_TOKEN

#配置API访问端点
$ export OS_URL=http://controller:35357/v3

# 配置API的版本
$ export OS_IDENTITY_API_VERSION=3

#创建`identity`服务实体
$ openstack service create \
    --name keystone --description "OpenStack Identity" identity

创建`identity`服务的访问端点`endpoint`

$ 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)，项目(projects)，用户(users)与角色(roles)

# 创建域`default`
$ openstack domain create --description "Default Domain" default

#创建项目`admin`
$ openstack project create --domain default \
    --description "Admin Project" admin

#创建用户`admin`
$ openstack user create --domain default \
    --password-prompt admin

#创建角色`admin`
$ openstack role create admin

#为项目`admin`与用户`admin`添加角色`admin`
$ openstack role add --project admin --user admin admin

#创建项目`service`
$ openstack project create --domain default \
    --description "Service Project" service

#创建项目`demo`
$ openstack project create --domain default \
    --description "Demo Project" demo

#创建用户`demo`
$ openstack user create --domain default \
    --password-prompt demo

#创建角色`user`
$ openstack role create user

# 为项目`demo`与用户`demo`添加角色`user`
$ openstack role add --project demo --user demo user

测试操作

+ 配置Keystone服务
```bash
$ vim /etc/keystone/keystone-paste.ini

# 文件内容
## 分别从[pipeline:public_api]，[pipeline:admin_api] 和 [pipeline:api_v3] 中移除 admin_token_auth
[pipeline:public_api]
pipeline = cors sizelimit url_normalize request_id build_auth_context token_auth json_body ec2_extension public_service
[pipeline:admin_api]
pipeline = cors sizelimit url_normalize request_id build_auth_context token_auth json_body ec2_extension s3_extension admin_service
[pipeline:api_v3]
pipeline = cors sizelimit url_normalize request_id build_auth_context token_auth json_body ec2_extension_v3 s3_extension service_v3
```
+ 移除临时令牌`token`与访问URL
```bash
$ unset OS_TOKEN OS_URL
```
+ 使用`amdin`用户请求令牌`token`
```bash
$ openstack --os-auth-url http://controller:35357/v3 \
    --os-project-domain-name default --os-user-domain-name default \
    --os-project-name admin --os-username admin token issue
```
+ 使用`demo`用户请求令牌(token)
```bash
$ 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

创建脚本

+ 为`admin`用户创建脚本
```bash
$ mkdir /openstack

$ vim /openstack/admin-openrc

# 文件内容
## <ADMIN_PASS>为demo用户的密码
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_PASS
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
```
+ 为`demo`用户创建脚本
```bash
$ vim /openstack/demo-openrc

# 文件内容
## <DEMO_PASS>为demo用户的密码
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_PASS
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
```

使用脚本

```bash
# 使用admin-openrc脚本
$ source /openstack/admin-openrc
# 使用demo-openrc脚本
$ source /openstack/demo-openrc
```
+ 请求令牌`token`
```bash
openstack token issue
