雲計算管理平台之OpenStack認證服務Keystone

  一、keystone簡介

  keystone是openstack中的核心服務,它主要作用是實現用戶認證和授權以及服務目錄;所謂服務目錄指所有可用服務的資訊庫,包含所有可用服務及其API endport路徑;簡單點講就是存儲各服務的API endport路徑和各服務的其他資訊;對於openstack的認證服務來講,有幾個核心的術語要了解下;

  user:這裡指使用openstack的用戶,一個用戶可以以關聯多個tenant(租戶)

  tenant:租戶,這裡的租戶指openstack上的項目project,或者一個組織;通常一個租戶對應一個project或一個組織;

  role:角色,這裡的角色類似Linux用戶里的用戶組概念,擁有授權為一個用戶為一個角色,那麼這個用戶就擁有這個角色所對應的許可權;

  token:令牌,用於認證和授權;這是另一種認證的方式;在openstack中各服務之間通過令牌來做認證的;

  service:服務,這個和我們理解的服務一樣,沒有特別的不一樣;

  endport:服務端點,通常指服務訪問入口;

  上述這些術語對應的數據,通常會用一個資料庫來存儲,我們把這個資料庫統稱為driver,對於不同類型的數據我們可以選擇不同的driver來存儲;比如對於token我們可以選擇存儲到k/v鍵值存儲系統中,也可以選擇存儲在memcached中或者mysql中;catalog我們可以選擇存儲在k/v鍵值存儲系統中,也可選擇存儲到mysql中,也可以選擇存儲到一個模板中;identity我們可以存儲k/v鍵值存儲系統中,也可選擇存儲到mysql中或者pam中也可以;

  提示:上圖是一個用戶在openstack上創建一個虛擬機內部驗證的過程;首先用戶要登入openstack上要把用戶的用戶名和密碼發送給keystone進行驗證,如果在keystone中驗證通過後,keystone會給用戶返回一個token,此時用戶就可以拿著這個返回的token去計算節點請求nova服務,進行創建虛擬機請求,在nova服務接受到用戶的請求後,nova它不能直接相信用戶的token是否是keystone給的,它會把這個token發送給keystone進行驗證,如果keystone驗證通過,此時nova才會拿著這個token去請求glance進行虛擬機鏡像請求,同樣的glance也不相信nova拿到這個token,它會去找keystone驗證,只有keystone通過後,glance才會把鏡像發送給nova,nova拿到鏡像啟動虛擬機;啟動虛擬機過程中nova還會拿著用戶的token去請求neutron服務給虛擬機分配網路,同樣neutron也是不相信nova的token,它也會去keystone上驗證token,只有驗證通過後才給nova創建的虛擬機分配網路;最後nova啟動好虛擬以後在返回,告訴用戶虛擬機啟動成功;從上面的過程來看,幾乎所有服務都會去keystone上驗證用戶的token,所以keystone服務會非常繁忙;

  二、keystone服務安裝、配置、測試

  1、創建資料庫

[root@node02 ~]# mysql
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 2
Server version: 10.1.20-MariaDB MariaDB Server

Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> CREATE DATABASE keystone;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> SHOW DATABASES;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| keystone           |
| mysql              |
| performance_schema |
| test               |
+--------------------+
5 rows in set (0.04 sec)

MariaDB [(none)]> 

  2、創建keystone用戶並授權允許從任何主機連接資料庫

MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%'  IDENTIFIED BY 'keystone123';
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> 

  驗證:在node01上使用keystone用戶連接資料庫,看看是否能夠正常連接?

[root@node01 ~]# mysql -ukeystone -pkeystone123 -hnode02
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 4
Server version: 10.1.20-MariaDB MariaDB Server

Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| keystone           |
| test               |
+--------------------+
3 rows in set (0.00 sec)

MariaDB [(none)]> 

  提示:能夠從別的主機用keystone帳號連接到mysql,並看到我們剛才創建的資料庫,說明我們創建的keystone帳號沒有問題;

  3、在控制節點安裝openstack-keystone、httpd和mod_wsgi

  qpid-proton-c.x86_64 0:0.32.0-2.el7                         

Complete!
[root@node01 ~]# 

  4、生成token

[root@node01 ~]# openssl  rand -hex 10
752e7981c9f3bb1b1a91
[root@node01 ~]# 

  5、編輯keystone配置文件/etc/keystone/keystone.conf,在default配置段里添加admin_token,把我們生成的token配置上;

  在database配置段配置連接資料庫的地址;

  提示:連接資料庫前邊的mysql+pymysql://這一段不用變,默認格式就是這個,雙斜線後面的是keystone用戶,冒號後面是對應keystone用戶的密碼;@後面是資料庫伺服器地址;斜線後面是指連接那個資料庫;我這裡是因為配置了主機名解析,所以資料庫伺服器我用主機名代替了;

  在token配置段配置provider = fernet

  keystone的最終配置

[root@node01 ~]# grep  "^[a-Z\[]" /etc/keystone/keystone.conf   
[DEFAULT]
admin_token = 752e7981c9f3bb1b1a91
[application_credential]
[assignment]
[auth]
[cache]
[catalog]

[token]
provider = fernet
[tokenless_auth]
[trust]
[unified_limit]
[wsgi]
[root@node01 ~]# 

  提示:這個配置文件是ini風格的配置文件,裡面有很多配置段,其實生效的就只有我們剛才配置的三段;

  6、在控制節點初始化keystone資料庫

[root@node01 ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone
[root@node01 ~]# 

  提示:以上命令會通過我們剛才配置的連接資料庫的地址,通過keystone連接到資料庫中創建一堆表;

  驗證:在node02上驗證,看看keystone庫中是否多了很多表?

  7、在控制節點上初始化Fernet密鑰

[root@node01 ~]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
[root@node01 ~]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
[root@node01 ~]# 

  提示:以上命令會在/etc/keystone/fernet-keys/目錄下生成兩個key文件;

  驗證:查看/etc/keystone/fernet-keys/目錄下是否有兩個key生成?

[root@node01 ~]# ll /etc/keystone/fernet-keys/
total 8
-rw------- 1 keystone keystone 44 Oct 28 19:23 0
-rw------- 1 keystone keystone 44 Oct 28 19:23 1
[root@node01 ~]# 

  8、配置httpd代理keystone

  提示:以上主要修改了httpd的servername監聽地址,其實這裡不修改也行,不影響;重要的是下面的配置;

  把/usr/share/keystone/wsgi-keystone.conf連接至/etc/httpd/conf.d/下

[root@node01 ~]# ln -sv /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/
『/etc/httpd/conf.d/wsgi-keystone.conf』 -> 『/usr/share/keystone/wsgi-keystone.conf』
[root@node01 ~]# ll /etc/httpd/conf.d/
total 16
-rw-r--r-- 1 root root 2926 Apr  2  2020 autoindex.conf
-rw-r--r-- 1 root root  366 Apr  2  2020 README
-rw-r--r-- 1 root root 1252 Nov 27  2019 userdir.conf
-rw-r--r-- 1 root root  824 Nov 27  2019 welcome.conf
lrwxrwxrwx 1 root root   38 Oct 28 19:30 wsgi-keystone.conf -> /usr/share/keystone/wsgi-keystone.conf
[root@node01 ~]# 

  提示:以上操作就是把httpd代理keystone的配置導入到httpd中,默認安裝keystone以後就會有一個這樣的配置文件;我們只需要把這個配置文件軟連接到httpd的配置目錄下即可;

  啟動httpd,並設置為開機啟動

[root@node01 ~]# systemctl start httpd
[root@node01 ~]# systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

LISTEN     0      100                               ::1:25                                             :::*                  
LISTEN     0      128                                :::5000                                           :::*                  
[root@node01 ~]# 

  提示:如果能夠看到5000埠正常監聽,說明我們導入的配置沒有問題;

  9、通過OS_TOKEN環境變數導出admin的token,使用OS_URL環境變數導出控制節點api介面地址,使用OS_IDENTITY_API_VERSION環境變數導出api的版本號

[root@node01 ~]# export  OS_TOKEN=752e7981c9f3bb1b1a91
[root@node01 ~]# export  OS_URL=//node01:5000/v3
[root@node01 ~]# export  OS_IDENTITY_API_VERSION=3

  提示:這裡的admin_token就是我們剛才在配置文件中配置的token;因為最開始我們只有手動生成一個token進行驗證;

  10、在導出以上三個環境變數的終端上創建域、用戶、項目、角色、服務;

  創建default域

[root@node01 ~]# openstack domain create --description "Default Domain" default
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | Default Domain                   |
| enabled     | True                             |
| id          | 47c0915c914c49bb8670703e4315a80f |
| name        | default                          |
| tags        | []                               |
+-------------+----------------------------------+
[root@node01 ~]# 

  創建一個admin的項目 並把域指向default

[root@node01 ~]# openstack project create --domain default --description "Admin Project" admin
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+

| domain_id   | 47c0915c914c49bb8670703e4315a80f |
| enabled     | True                             |
| id          | b4e56eeb160948c581e98d685133d19a |
| is_domain   | False                            |
| name        | admin                            |
| parent_id   | 47c0915c914c49bb8670703e4315a80f |
| tags        | []                               |
+-------------+----------------------------------+
[root@node01 ~]# 

  創建admin用戶並設置密碼為admin

[root@node01 ~]# openstack user create --domain default --password-prompt admin
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+

| enabled             | True                             |
| id                  | a105f256dc9f42438212e9d96d46b60d |
| name                | admin                            |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+
[root@node01 ~]# 

  創建admin角色

[root@node01 ~]# openstack role create admin
+-----------+----------------------------------+
| Field     | Value                            |
+-----------+----------------------------------+
| domain_id | None                             |
| id        | 7f1f7aa119034c2fbd15b46b90632d18 |
| name      | admin                            |
+-----------+----------------------------------+
[root@node01 ~]# 

  給admin用戶授權,將admin用戶授予admin項目的admin角色

[root@node01 ~]# openstack role add --project admin --user admin admin
[root@node01 ~]# 

  創建一個用於測試的demo項目

[root@node01 ~]# openstack project create --domain default --description "Demo Project" demo
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | Demo Project                     |
| domain_id   | 47c0915c914c49bb8670703e4315a80f |
| enabled     | True                             |
| id          | 1a918887f38a42c28f9d0d3774f34b16 |
| is_domain   | False                            |
| name        | demo                             |
| parent_id   | 47c0915c914c49bb8670703e4315a80f |
| tags        | []                               |
+-------------+----------------------------------+
[root@node01 ~]# 

  創建demo用戶並設置密碼為demo

[root@node01 ~]# openstack user create --domain default --password-prompt demo
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | 47c0915c914c49bb8670703e4315a80f |
| enabled             | True                             |
| id                  | 5453d68782a34429a7dab7da9c51f0d9 |
| name                | demo                             |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+
[root@node01 ~]# 

  創建一個user角色

[root@node01 ~]# openstack role create user
+-----------+----------------------------------+
| Field     | Value                            |
+-----------+----------------------------------+
| domain_id | None                             |
| id        | ee2f38096e42409eb47ae67a8c289279 |
| name      | user                             |
+-----------+----------------------------------+
[root@node01 ~]# 

  把demo用戶添加到demo項目,然後賦予user角色許可權

[root@node01 ~]# openstack role add --project demo --user demo user
[root@node01 ~]# 

  驗證:查看現有的用戶、項目、角色、域是否是我們創建的

[root@node01 ~]# openstack user list
+----------------------------------+-------+
| ID                               | Name  |
+----------------------------------+-------+
| 5453d68782a34429a7dab7da9c51f0d9 | demo  |
| a105f256dc9f42438212e9d96d46b60d | admin |
+----------------------------------+-------+
[root@node01 ~]# openstack project list
+----------------------------------+-------+
| ID                               | Name  |
+----------------------------------+-------+
| 1a918887f38a42c28f9d0d3774f34b16 | demo  |
| b4e56eeb160948c581e98d685133d19a | admin |

+----------------------------------+---------+---------+----------------+
[root@node01 ~]# 

  提示:可以看到當前控制節點上有兩個用戶,兩個項目,兩個角色,分別是admin和demo;一個default域;這都是我們剛才創建的;

  創建一個service項目,各服務之間與keystone進行訪問和認證,service用於給服務創建用戶;

[root@node01 ~]# openstack project create --domain default   --description "Service Project" service
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | Service Project                  |
| domain_id   | 47c0915c914c49bb8670703e4315a80f |
| enabled     | True                             |
| id          | 9c9d6f24fc23464a810ef97ce199bffa |
| is_domain   | False                            |
| name        | service                          |
| parent_id   | 47c0915c914c49bb8670703e4315a80f |
| tags        | []                               |
+-------------+----------------------------------+
[root@node01 ~]# 

  創建一個keystone認證服務

[root@node01 ~]# openstack service create  --name keystone --description "OpenStack Identity" identity
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Identity               |
| enabled     | True                             |
| id          | a32cffed26924a87b21b4e86e00c63b4 |
| name        | keystone                         |
| type        | identity                         |
+-------------+----------------------------------+
[root@node01 ~]# 

  查看當前服務列表

[root@node01 ~]# openstack service list
+----------------------------------+----------+----------+
| ID                               | Name     | Type     |

| a32cffed26924a87b21b4e86e00c63b4 | keystone | identity |
+----------------------------------+----------+----------+
[root@node01 ~]# 

  11、創建endpoint(註冊服務)

  創建公共端

[root@node01 ~]# openstack endpoint create --region RegionOne identity public //controller:5000/v3
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| enabled      | True                             |
| id           | 5293ad18db674ea1b01d8f401cb2cf14 |
| interface    | public                           |
| region       | RegionOne                        |
| region_id    | RegionOne                        |
| service_id   | a32cffed26924a87b21b4e86e00c63b4 |
| service_name | keystone                         |
| service_type | identity                         |
| url          | //controller:5000/v3        |
+--------------+----------------------------------+
[root@node01 ~]# 

  創建私有端

[root@node01 ~]# openstack endpoint create --region RegionOne identity internal //controller:5000/v3
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| enabled      | True                             |
| id           | 6593f8d808094b01a6311828f2ef72bd |
| interface    | internal                         |
| region       | RegionOne                        |
| region_id    | RegionOne                        |
| service_id   | a32cffed26924a87b21b4e86e00c63b4 |
| service_name | keystone                         |
| service_type | identity                         |
| url          | //controller:5000/v3        |
+--------------+----------------------------------+
[root@node01 ~]# 

  創建管理端

[root@node01 ~]# openstack endpoint create --region RegionOne identity admin //controller:5000/v3
+--------------+----------------------------------+
| Field        | Value                            |
+--------------+----------------------------------+
| enabled      | True                             |
| id           | 3bd05493999b462eb4b4af8d5e5c1fa9 |
| interface    | admin                            |
| region       | RegionOne                        |
| region_id    | RegionOne                        |
| service_id   | a32cffed26924a87b21b4e86e00c63b4 |
| service_name | keystone                         |
| service_type | identity                         |
| url          | //controller:5000/v3        |
+--------------+----------------------------------+
[root@node01 ~]# 

  驗證:看看endport 列表是否都已經有我們剛才創建的三個端點?

[root@node01 ~]# openstack endpoint list
+----------------------------------+-----------+--------------+--------------+---------+-----------+---------------------------+
| ID                               | Region    | Service Name | Service Type | Enabled | Interface | URL                       |
+----------------------------------+-----------+--------------+--------------+---------+-----------+---------------------------+
| 3bd05493999b462eb4b4af8d5e5c1fa9 | RegionOne | keystone     | identity     | True    | admin     | //controller:5000/v3 |
| 5293ad18db674ea1b01d8f401cb2cf14 | RegionOne | keystone     | identity     | True    | public    | //controller:5000/v3 |
| 6593f8d808094b01a6311828f2ef72bd | RegionOne | keystone     | identity     | True    | internal  | //controller:5000/v3 |
+----------------------------------+-----------+--------------+--------------+---------+-----------+---------------------------+
[root@node01 ~]# 

  提示:如果創建錯誤或者多創建了,就需要全部刪除,重新註冊;

  到此keystone服務就配置完了;接下來測試keystone是否可以用來做認證服務

  驗證:重新打開一個終端窗口,導出OS_IDENTITY_API_VERSION環境變數,使用命令的方式驗證admin用戶密碼是admin

[root@node01 ~]# echo $OS_IDENTITY_API_VERSION

[root@node01 ~]# export OS_IDENTITY_API_VERSION=3
[root@node01 ~]# echo $OS_IDENTITY_API_VERSION   
3
[root@node01 ~]# openstack --os-auth-url //node01:5000/v3 --os-project-domain-name default --os-user-domain-name default  --os-project-name admin  --os-username admin token issue

  提示:有了上面兩個腳本以後,我們就實現要使用那個用戶測試,直接把對應的用戶環境變數導出即可;

  驗證:測試admin用戶的環境變數腳本是否可用?

  提示:重新開一個終端,導出admin用戶環境變數,然後直接使用openstack token issue命令就能驗證admin用戶;有了這個環境變數腳本,我們不用輸密碼和不用寫那麼長的命令了;

  驗證demo用戶的環境變數腳本

  提示:demo用戶的環境變數腳本也都能夠正常通過驗證;到此keystone服務的安裝配置測試就完成了;
