云计算管理平台之OpenStack认证服务Keystone
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；
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 Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * centos-qemu-ev: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Resolving Dependencies --> Running transaction check ---> Package httpd.x86_64 0:2.4.6-93.el7.centos will be installed --> Processing Dependency: httpd-tools = 2.4.6-93.el7.centos for package: httpd-2.4.6-93.el7.centos.x86_64 --> Processing Dependency: /etc/mime.types for package: httpd-2.4.6-93.el7.centos.x86_64 --> Processing Dependency: libaprutil-1.so.0()(64bit) for package: httpd-2.4.6-93.el7.centos.x86_64 --> Processing Dependency: libapr-1.so.0()(64bit) for package: httpd-2.4.6-93.el7.centos.x86_64 ---> Package mod_wsgi.x86_64 0:3.4-18.el7 will be installed ……省略部分内容…… Dependency Installed: MySQL-python.x86_64 0:1.2.5-1.el7 apr.x86_64 0:1.4.8-5.el7 apr-util.x86_64 0:1.5.2-6.el7 httpd-tools.x86_64 0:2.4.6-93.el7.centos mailcap.noarch 0:2.1.41-2.el7 python-aniso8601.noarch 0:0.82-3.el7 python-beaker.noarch 0:1.5.4-10.el7 python-editor.noarch 0:0.4-4.el7 python-jwcrypto.noarch 0:0.4.2-1.el7 python-keystone.noarch 1:14.2.0-1.el7 python-mako.noarch 0:0.8.1-2.el7 python-migrate.noarch 0:0.11.0-1.el7 python-oslo-cache-lang.noarch 0:1.30.4-1.el7 python-oslo-concurrency-lang.noarch 0:3.27.0-1.el7 python-oslo-db-lang.noarch 0:4.40.2-1.el7 python-oslo-middleware-lang.noarch 0:3.36.0-1.el7 python-oslo-policy-lang.noarch 0:1.38.1-1.el7 python-paste.noarch 0:1.7.5.1-9.20111221hg1498.el7 python-paste-deploy.noarch 0:1.5.2-6.el7 python-pycadf-common.noarch 0:2.8.0-1.el7 python-routes.noarch 0:2.4.1-1.el7 python-sqlparse.noarch 0:0.1.18-5.el7 python-tempita.noarch 0:0.5.1-8.el7 python2-alembic.noarch 0:0.9.7-1.el7 python2-amqp.noarch 0:2.4.0-1.el7 python2-bcrypt.x86_64 0:3.1.6-2.el7 python2-cachetools.noarch 0:2.1.0-1.el7 python2-click.noarch 0:6.7-8.el7 python2-defusedxml.noarch 0:0.5.0-2.el7 python2-eventlet.noarch 0:0.20.1-6.el7 python2-fasteners.noarch 0:0.14.1-6.el7 python2-flask.noarch 1:1.0.2-1.el7 python2-flask-restful.noarch 0:0.3.6-7.el7 python2-future.noarch 0:0.18.2-2.el7 python2-futurist.noarch 0:1.7.0-1.el7 python2-greenlet.x86_64 0:0.4.12-1.el7 python2-itsdangerous.noarch 0:0.24-14.el7 python2-jinja2.noarch 0:2.10-2.el7 python2-keystonemiddleware.noarch 0:5.2.2-1.el7 python2-kombu.noarch 1:4.2.2-1.el7 python2-ldap.x86_64 0:3.1.0-1.el7 python2-ldappool.noarch 0:2.3.1-1.el7 python2-markupsafe.x86_64 0:0.23-16.el7 python2-oauthlib.noarch 0:2.0.1-8.el7 python2-oslo-cache.noarch 0:1.30.4-1.el7 python2-oslo-concurrency.noarch 0:3.27.0-1.el7 python2-oslo-db.noarch 0:4.40.2-1.el7 python2-oslo-messaging.noarch 0:8.1.4-1.el7 python2-oslo-middleware.noarch 0:3.36.0-1.el7 python2-oslo-policy.noarch 0:1.38.1-1.el7 python2-oslo-service.noarch 0:1.31.8-1.el7 python2-osprofiler.noarch 0:2.3.1-1.el7 python2-passlib.noarch 0:1.7.1-1.el7 python2-pyasn1.noarch 0:0.3.7-6.el7 python2-pyasn1-modules.noarch 0:0.3.7-6.el7 python2-pycadf.noarch 0:2.8.0-1.el7 python2-pyngus.noarch 0:2.3.0-1.el7 python2-pysaml2.noarch 0:4.5.0-4.el7 python2-qpid-proton.x86_64 0:0.32.0-2.el7 python2-scrypt.x86_64 0:0.8.0-2.el7 python2-sqlalchemy.x86_64 0:1.2.7-1.el7 python2-statsd.noarch 0:3.2.1-5.el7 python2-tenacity.noarch 0:4.12.0-1.el7 python2-vine.noarch 0:1.2.0-1.el7 python2-webob.noarch 0:1.8.2-1.el7 python2-werkzeug.noarch 0:0.14.1-3.el7 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、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] [assignment] [auth] [cache] [catalog] [cors] [credential] [database] connection = mysql+pymysql://keystone:keystone123@node02/keystone [domain_config] [endpoint_filter] [endpoint_policy] [eventlet_server] [federation] [fernet_tokens] [healthcheck] [identity] [identity_mapping] [ldap] [matchmaker_redis] [memcache] [oauth1] [oslo_messaging_amqp] [oslo_messaging_kafka] [oslo_messaging_notifications] [oslo_messaging_rabbit] [oslo_messaging_zmq] [oslo_middleware] [oslo_policy] [policy] [profiler] [resource] [revoke] [role] [saml] [security_compliance] [shadow_users] [signing] [token] provider = fernet [tokenless_auth] [trust] [unified_limit] [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？
MariaDB [(none)]> use keystone Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed MariaDB [keystone]> show tables; +-----------------------------+ | Tables_in_keystone | +-----------------------------+ | access_token | | application_credential | | application_credential_role | | assignment | | config_register | | consumer | | credential | | endpoint | | endpoint_group | | federated_user | | federation_protocol | | group | | id_mapping | | identity_provider | | idp_remote_ids | | implied_role | | limit | | local_user | | mapping | | migrate_version | | nonlocal_user | | password | | policy | | policy_association | | project | | project_endpoint | | project_endpoint_group | | project_tag | | region | | registered_limit | | request_token | | revocation_event | | role | | sensitive_config | | service | | service_provider | | system_assignment | | token | | trust | | trust_role | | user | | user_group_membership | | user_option | | whitelisted_config | +-----------------------------+ 44 rows in set (0.00 sec) MariaDB [keystone]>
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 | +-------------+----------------------------------+ | description | Default Domain | | enabled | True | | id | 47c0915c914c49bb8670703e4315a80f | | name | default | | tags | [] | +-------------+----------------------------------+ [root@node01 ~]#
创建一个admin的项目 并把域指向default
[root@node01 ~]# openstack project create --domain default --description "Admin Project" admin +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | Admin Project | | domain_id | 47c0915c914c49bb8670703e4315a80f | | enabled | True | | id | b4e56eeb160948c581e98d685133d19a | | is_domain | False | | name | admin | | parent_id | 47c0915c914c49bb8670703e4315a80f | | tags | [] | +-------------+----------------------------------+ [root@node01 ~]#
创建admin用户并设置密码为admin
[root@node01 ~]# openstack user create --domain default --password-prompt admin
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | 47c0915c914c49bb8670703e4315a80f |
| enabled | True |
| id | a105f256dc9f42438212e9d96d46b60d |
| name | admin |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+
[root@node01 ~]#
创建admin角色
[root@node01 ~]# openstack role create admin +-----------+----------------------------------+ | Field | Value | +-----------+----------------------------------+ | domain_id | None | | id | 7f1f7aa119034c2fbd15b46b90632d18 | | name | admin | +-----------+----------------------------------+ [root@node01 ~]#
给admin用户授权，将admin用户授予admin项目的admin角色
[root@node01 ~]# openstack role add --project admin --user admin admin [root@node01 ~]#
创建一个用于测试的demo项目
[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 ~]#
创建demo用户并设置密码为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 ~]#
创建一个user角色
[root@node01 ~]# openstack role create user +-----------+----------------------------------+ | Field | Value | +-----------+----------------------------------+ | domain_id | None | | id | ee2f38096e42409eb47ae67a8c289279 | | name | user | +-----------+----------------------------------+ [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 +----------------------------------+-------+ | ID | Name | +----------------------------------+-------+ | 5453d68782a34429a7dab7da9c51f0d9 | demo | | a105f256dc9f42438212e9d96d46b60d | admin | +----------------------------------+-------+ [root@node01 ~]# openstack project list +----------------------------------+-------+ | ID | Name | +----------------------------------+-------+ | 1a918887f38a42c28f9d0d3774f34b16 | demo | | b4e56eeb160948c581e98d685133d19a | admin | +----------------------------------+-------+ [root@node01 ~]# openstack role list +----------------------------------+-------+ | ID | Name | +----------------------------------+-------+ | 7f1f7aa119034c2fbd15b46b90632d18 | admin | | ee2f38096e42409eb47ae67a8c289279 | user | +----------------------------------+-------+ [root@node01 ~]# openstack domain list +----------------------------------+---------+---------+----------------+ | ID | Name | Enabled | Description | +----------------------------------+---------+---------+----------------+ | 47c0915c914c49bb8670703e4315a80f | default | True | Default Domain | +----------------------------------+---------+---------+----------------+ [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 +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | Service Project | | domain_id | 47c0915c914c49bb8670703e4315a80f | | enabled | True | | id | 9c9d6f24fc23464a810ef97ce199bffa | | is_domain | False | | name | service | | parent_id | 47c0915c914c49bb8670703e4315a80f | | tags | [] | +-------------+----------------------------------+ [root@node01 ~]#
创建一个keystone认证服务
[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 ~]#
查看当前服务列表
[root@node01 ~]# openstack service list +----------------------------------+----------+----------+ | ID | Name | Type | +----------------------------------+----------+----------+ | a32cffed26924a87b21b4e86e00c63b4 | keystone | identity | +----------------------------------+----------+----------+ [root@node01 ~]#
11、创建endpoint（注册服务）
创建公共端
[root@node01 ~]# openstack endpoint create --region RegionOne identity public http://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 | http://controller:5000/v3 | +--------------+----------------------------------+ [root@node01 ~]#
创建私有端
[root@node01 ~]# openstack endpoint create --region RegionOne identity internal http://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 | http://controller:5000/v3 | +--------------+----------------------------------+ [root@node01 ~]#
创建管理端
[root@node01 ~]# openstack endpoint create --region RegionOne identity admin http://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 | http://controller:5000/v3 | +--------------+----------------------------------+ [root@node01 ~]#
验证：看看endport 列表是否都已经有我们刚才创建的三个端点？
[root@node01 ~]# openstack endpoint list +----------------------------------+-----------+--------------+--------------+---------+-----------+---------------------------+ | ID | Region | Service Name | Service Type | Enabled | Interface | URL | +----------------------------------+-----------+--------------+--------------+---------+-----------+---------------------------+ | 3bd05493999b462eb4b4af8d5e5c1fa9 | RegionOne | keystone | identity | True | admin | http://controller:5000/v3 | | 5293ad18db674ea1b01d8f401cb2cf14 | RegionOne | keystone | identity | True | public | http://controller:5000/v3 | | 6593f8d808094b01a6311828f2ef72bd | RegionOne | keystone | identity | True | internal | http://controller:5000/v3 | +----------------------------------+-----------+--------------+--------------+---------+-----------+---------------------------+ [root@node01 ~]#
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 Password: +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Field | Value | +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | expires | 2020-10-28T13:16:54+0000 | | id | gAAAAABfmWE2udKuo4ambgxh3RsrzoDwrA8IHa1dx5gYk_sZoU5HmZUM9qHTguwMasYGzRIno0LawlZDbB4i3IJold3sZdAlEZGwiNuPtYJMgP5nikDUR8YrXNPNQNDMjCchDMMN6bWhZ26pQXVEZ0VXcN5v5xOj_bx7nskJ8bnvKWFiRf4ckPQ | | project_id | b4e56eeb160948c581e98d685133d19a | | user_id | a105f256dc9f42438212e9d96d46b60d | +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ [root@node01 ~]#
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 Password: The request you have made requires authentication. (HTTP 401) (Request-ID: req-79d8afbe-56dc-47f9-ab4e-8065a295923e) [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 total 8 -rwxr-xr-x 1 root root 272 Oct 28 20:23 admin.sh -rwxr-xr-x 1 root root 269 Oct 28 20:24 demo.sh [root@node01 ~]# source admin.sh [root@node01 ~]# openstack token issue +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Field | Value | +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | expires | 2020-10-28T13:29:08+0000 | | id | gAAAAABfmWQU2Z97wzxv94lLY4hcSWe4X6Udp_OyeYw3_wY54_znLFb4TFLcMnR96-ogNAcJEvXiQcJWdvQJHBObYbR-gAEulagQq2sjXLxedMYLUN4j2y_L4G5NhbaogGKtHed4WMR0N72Js4INyHjKWCwwSd2d4NJpZUe14pQjNX8ihleP09g | | project_id | b4e56eeb160948c581e98d685133d19a | | user_id | a105f256dc9f42438212e9d96d46b60d | +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ [root@node01 ~]#
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
[root@node01 ~]# ll total 8 -rwxr-xr-x 1 root root 272 Oct 28 20:23 admin.sh -rwxr-xr-x 1 root root 269 Oct 28 20:24 demo.sh [root@node01 ~]# source demo.sh [root@node01 ~]# openstack token issue +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Field | Value | +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | expires | 2020-10-28T13:31:34+0000 | | id | gAAAAABfmWSmj5PHp8x3m3szKwZ0_dWSdY-JM-TBbo-bMk4OaTHl3BLNVrglKXRMe5jpbCOBPb5l2AyHWVvzvJdi2Jx4va7PJksJGlx_JluhOx9vry1kjiZoKcW7Ri3Y7qkYFvDcpDHXy0KkYeHSyMW9zjNaFvvJtrPpozgfw7gsghYJNfZoYz0 | | project_id | 1a918887f38a42c28f9d0d3774f34b16 | | user_id | 5453d68782a34429a7dab7da9c51f0d9 | +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ [root@node01 ~]#
提示：demo用户的环境变量脚本也都能够正常通过验证；到此keystone服务的安装配置测试就完成了；
