3.openstack之mitaka搭建keystone认证服务
认证服务keystone部署
一：安装和配置服务
1.建库建用户
mysql -u root -p
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '密码';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '密码';
flush privileges;
2.安装httpdweb服务器
yum install openstack-keystone httpd mod_wsgi -y
3.编辑/etc/keystone/keystone.conf
创建秘钥
# openssl rand -hex 10
ada2c9751d94be18d74a
#vim /etc/keystone/keystone.conf
[DEFAULT]
admin_token = ada2c9751d94be18d74a #建议用命令制作token:openssl rand -hex 10
[database]
connection = mysql+pymysql://keystone:liuyao@controller/keystone
[token]
provider = fernet
#学习博客
#Token Provider：UUID, PKI, PKIZ, or Fernet #http://blog.csdn.net/miss_yang_cloud/article/details/49633719
4.同步修改到数据库
#su -s /bin/sh -c "keystone-manage db_sync" keystone
5.初始化fernet keys
#keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
6.配置apache服务
编辑：/etc/httpd/conf/httpd.conf
ServerName controller
编辑：/etc/httpd/conf.d/wsgi-keystone.conf
新增配置
Listen 5000
Listen 35357
<VirtualHost *:5000>
WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-public
WSGIScriptAlias / /usr/bin/keystone-wsgi-public
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
Require all granted
</Directory>
</VirtualHost>
<VirtualHost *:35357>
WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-admin
WSGIScriptAlias / /usr/bin/keystone-wsgi-admin
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
Require all granted
</Directory>
</VirtualHost>
7.启动服务:
systemctl enable httpd.service
systemctl start httpd.service
二：创建服务实体和访问端点
1.实现配置管理员环境变量，用于获取后面创建的权限
export OS_TOKEN=ada2c9751d94be18d74a #此token是上面生成的
export OS_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
2.基于上一步给的权限，创建认证服务实体（目录服务）
#openstack service create \
--name keystone --description "OpenStack Identity" identity
3.基于上一步建立的服务实体，创建访问该实体的三个api端点
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
三：创建域，租户，用户，角色，把四个元素关联到一起
建立一个公共的域名：
#openstack domain create --description "Default Domain" default
管理员：admin
openstack project create --domain default \
--description "Admin Project" admin
openstack user create --domain default \
--password-prompt admin
openstack role create admin
openstack role add --project admin --user admin admin
普通用户：demo
openstack project create --domain default \
--description "Demo Project" demo
openstack user create --domain default \
--password-prompt demo
openstack role create user
openstack role add --project demo --user demo user
为后续的服务创建统一租户service
解释：后面每搭建一个新的服务都需要在keystone中执行四种操作：1.建租户 2.建用户 3.建角色 4.做关联
后面所有的服务公用一个租户service，都是管理员角色admin，所以实际上后续的服务安装关于keysotne
的操作只剩2，4
openstack project create --domain default \
--description "Service Project" service
四：验证操作：
编辑：/etc/keystone/keystone-paste.ini
在[pipeline:public_api], [pipeline:admin_api], and [pipeline:api_v3] 三个地方
移走：admin_token_auth
unset OS_TOKEN OS_URL
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
Password:

五：新建客户端脚本文件
管理员：admin-openrc
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=liuyao
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
普通用户demo：demo-openrc
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=liuyao
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
效果：
source admin-openrc
[root@controller01 ~]# openstack token issue
