云计算管理平台之OpenStack认证服务Keystone
一、keystone简介
keystone是openstack中的核心服务,它主要作用是实现用户认证和授权以及服务目录;所谓服务目录指所有可用服务的信息库,包含所有可用服务及其API endport路径;简单点讲就是存储各服务的API endport路径和各服务的其他信息;对于openstack的认证服务来讲,有几个核心的术语要了解下;
user:这里指使用openstack的用户,一个用户可以以关联多个tenant(租户)
tenant:租户,这里的租户指openstack上的项目project,或者一个组织;通常一个租户对应一个project或一个组织;
role:角色,这里的角色类似Linux用户里的用户组概念,拥有授权为一个用户为一个角色,那么这个用户就拥有这个角色所对应的权限;
token:令牌,用于认证和授权;这是另一种认证的方式;在openstack中各服务之间通过令牌来做认证的;
service:服务,这个和我们理解的服务一样,没有特别的不一样;
endport:服务端点,通常指服务访问入口;
上述这些术语对应的数据,通常会用一个数据库来存储,我们把这个数据库统称为driver,对于不同类型的数据我们可以选择不同的driver来存储;比如对于token我们可以选择存储到k/v键值存储系统中,也可以选择存储在memcached中或者mysql中;catalog我们可以选择存储在k/v键值存储系统中,也可选择存储到mysql中,也可以选择存储到一个模板中;identity我们可以存储k/v键值存储系统中,也可选择存储到mysql中或者pam中也可以;
提示:上图是一个用户在openstack上创建一个虚拟机内部验证的过程;首先用户要登入openstack上要把用户的用户名和密码发送给keystone进行验证,如果在keystone中验证通过后,keystone会给用户返回一个token,此时用户就可以拿着这个返回的token去计算节点请求nova服务,进行创建虚拟机请求,在nova服务接受到用户的请求后,nova它不能直接相信用户的token是否是keystone给的,它会把这个token发送给keystone进行验证,如果keystone验证通过,此时nova才会拿着这个token去请求glance进行虚拟机镜像请求,同样的glance也不相信nova拿到这个token,它会去找keystone验证,只有keystone通过后,glance才会把镜像发送给nova,nova拿到镜像启动虚拟机;启动虚拟机过程中nova还会拿着用户的token去请求neutron服务给虚拟机分配网络,同样neutron也是不相信nova的token,它也会去keystone上验证token,只有验证通过后才给nova创建的虚拟机分配网络;最后nova启动好虚拟以后在返回,告诉用户虚拟机启动成功;从上面的过程来看,几乎所有服务都会去keystone上验证用户的token,所以keystone服务会非常繁忙;
二、keystone服务安装、配置、测试
1、创建数据库
[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、创建keystone用户并授权允许从任何主机连接数据库
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)]>
验证:在node01上使用keystone用户连接数据库,看看是否能够正常连接?
[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:能够从别的主机用keystone账号连接到mysql,并看到我们刚才创建的数据库,说明我们创建的keystone账号没有问题;
3、在控制节点安装openstack-keystone、httpd和mod_wsgi
[root@node01 ~]# yum install -y openstack-keystone httpd mod_wsgi

[root@node01 ~]#
4、生成token
[root@node01 ~]# openssl rand -hex 10
752e7981c9f3bb1b1a91
[root@node01 ~]#
5、编辑keystone配置文件/etc/keystone/keystone.conf,在default配置段里添加admin_token,把我们生成的token配置上;
在database配置段配置连接数据库的地址;
提示:连接数据库前边的mysql+pymysql://这一段不用变,默认格式就是这个,双斜线后面的是keystone用户,冒号后面是对应keystone用户的密码;@后面是数据库服务器地址;斜线后面是指连接那个数据库;我这里是因为配置了主机名解析,所以数据库服务器我用主机名代替了;
在token配置段配置provider = fernet
keystone的最终配置
[root@node01 ~]# grep "^[a-Z\[]" /etc/keystone/keystone.conf
[DEFAULT]
admin_token = 752e7981c9f3bb1b1a91
[application_credential]

[wsgi]
[root@node01 ~]#
提示:这个配置文件是ini风格的配置文件,里面有很多配置段,其实生效的就只有我们刚才配置的三段;
6、在控制节点初始化keystone数据库
[root@node01 ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone
[root@node01 ~]#
提示:以上命令会通过我们刚才配置的连接数据库的地址,通过keystone连接到数据库中创建一堆表;
验证:在node02上验证,看看keystone库中是否多了很多表?

7、在控制节点上初始化Fernet密钥
[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:以上命令会在/etc/keystone/fernet-keys/目录下生成两个key文件;
验证:查看/etc/keystone/fernet-keys/目录下是否有两个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监听地址,其实这里不修改也行,不影响;重要的是下面的配置;
把/usr/share/keystone/wsgi-keystone.conf连接至/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的配置导入到httpd中,默认安装keystone以后就会有一个这样的配置文件;我们只需要把这个配置文件软连接到httpd的配置目录下即可;
启动httpd,并设置为开机启动
[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.
[root@node01 ~]# ss -tnl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:22 *:*
LISTEN 0 100 127.0.0.1:25 *:*
LISTEN 0 128 :::80 :::*
LISTEN 0 128 :::22 :::*
LISTEN 0 100 ::1:25 :::*
LISTEN 0 128 :::5000 :::*
[root@node01 ~]#
提示:如果能够看到5000端口正常监听,说明我们导入的配置没有问题;
9、通过OS_TOKEN环境变量导出admin的token,使用OS_URL环境变量导出控制节点api接口地址,使用OS_IDENTITY_API_VERSION环境变量导出api的版本号
[root@node01 ~]# export OS_TOKEN=752e7981c9f3bb1b1a91
[root@node01 ~]# export OS_URL=http://node01:5000/v3
[root@node01 ~]# export OS_IDENTITY_API_VERSION=3
提示:这里的admin_token就是我们刚才在配置文件中配置的token;因为最开始我们只有手动生成一个token进行验证;
10、在导出以上三个环境变量的终端上创建域、用户、项目、角色、服务;
创建default域
[root@node01 ~]# openstack domain create --description "Default Domain" default
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+

[root@node01 ~]#
把demo用户添加到demo项目,然后赋予user角色权限
[root@node01 ~]# openstack role add --project demo --user demo user
[root@node01 ~]#
验证:查看现有的用户、项目、角色、域是否是我们创建的
[root@node01 ~]# openstack user list

[root@node01 ~]#
提示:可以看到当前控制节点上有两个用户,两个项目,两个角色,分别是admin和demo;一个default域;这都是我们刚才创建的;
创建一个service项目,各服务之间与keystone进行访问和认证,service用于给服务创建用户;
[root@node01 ~]# openstack project create --domain default --description "Service Project" service

提示:如果创建错误或者多创建了,就需要全部删除,重新注册;
到此keystone服务就配置完了;接下来测试keystone是否可以用来做认证服务
验证:重新打开一个终端窗口,导出OS_IDENTITY_API_VERSION环境变量,使用命令的方式验证admin用户密码是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 http://node01:5000/v3 --os-project-domain-name default --os-user-domain-name default --os-project-name admin --os-username admin token issue

提示:输入正确的密码会返回一个表,记录的有过期时长,id,和项目id和用户id;如果输入密码错误则不会返回这些内容,其实这些内容主要用来描述返回给用户token属性,我们可以理解它就是返回了这样一个token给我们;
[root@node01 ~]# openstack --os-auth-url http://node01:5000/v3 --os-project-domain-name default --os-user-domain-name default --os-project-name admin --os-username admin token issue

[root@node01 ~]#
提示:输入错误的密码它给我们返回了响应码为401,表示验证未通过;
创建admin用户环境变量脚本
[root@node01 ~]# cat admin.sh
#!/bin/bash
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:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
[root@node01 ~]# chmod a+x admin.sh
[root@node01 ~]#
创建demo用户环境变量脚本
[root@node01 ~]# cat demo.sh
#!/bin/bash
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_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
[root@node01 ~]# chmod a+x demo.sh
[root@node01 ~]#
提示:有了上面两个脚本以后,我们就实现要使用那个用户测试,直接把对应的用户环境变量导出即可;
验证:测试admin用户的环境变量脚本是否可用?
[root@node01 ~]# ll

提示:重新开一个终端,导出admin用户环境变量,然后直接使用openstack token issue命令就能验证admin用户;有了这个环境变量脚本,我们不用输密码和不用写那么长的命令了;
验证demo用户的环境变量脚本
