二、ctrl节点
2.1必要的软件安装
yum -y install python-openstackclient ##python软件包安装
yum -y install openstack-selinux ##python模块安装
yum -y install openstack-keystone httpd mod_wsgi
2.2和数据库做关联
vim /etc/keystone/keystone.conf ##通过密码访问base节点keystone的数据库，做keystone组件与数据库的连接，token采用的加密方式 fernet
[database]
Connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@base.blue.edu/keystone
[token]
provider = fernet
su -s /bin/sh -c "keystone-manage db_sync" keystone ##同步数据
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
##给keystone用户以及所在的组进行加密
keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
##给keystone用户配置凭证
keystone-manage bootstrap --bootstrap-password ADMIN_PASS \
--bootstrap-admin-url http://ctrl.blue.edu:35357/v3/ \
--bootstrap-internal-url http://ctrl.blue.edu:5000/v3/ \
--bootstrap-public-url http://ctrl.blue.edu:5000/v3/ \
--bootstrap-region-id RegionOne
##给keystone声明访问点设置通道，密码为ADMIN_PASS
2.3给keystone 提供http服务
vim /etc/httpd/conf/httpd.conf
serverName ctrl.xiaoai.edu
ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/
##软连接建立,当每个组件做认证注册时，默认的token+URL以HTTP服务形式访问
2.4声明环境变量
export OS_USERNAME=admin
export OS_PASSWORD=ADMIN_PASS
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://ctrl.blue.edu:35357/v3
export OS_IDENTITY_API_VERSION=3
2.5openstack环境的设置
openstack project create --domain default --description "Service Project" service
openstack project create --domain default --description "Demo Project" demo
openstack user create --domain default --password DEMO_PASS demo
openstack role create user
openstack role add --project demo --user demo user
##创建用户密码，创建角色，给demo项目下的用户赋予user角色;在default域下创建service项目非管理员任务应用非特权项目和用户。在defalut域下创建Demo项目创建demo用户密码DEMO_PASS;创建user角色将User角色添加到demo项目和demo用户
2.6编辑openstack配置文件
cp /etc/keystone/keystone-paste.ini /etc/keystone/keystone-paste.ini.ds.bak
vim /etc/keystone/keystone-paste.ini
[pipeline:public_api]
# The last item in this pipeline must be public_service or an equivalent
# application. It cannot be a filter.
pipeline = healthcheck cors sizelimit http_proxy_to_wsgi osprofiler url_normalize request_id build_auth_context token_auth json_body ec2_extension public_service
[pipeline:admin_api]
# The last item in this pipeline must be admin_service or an equivalent
# application. It cannot be a filter.
pipeline = healthcheck cors sizelimit http_proxy_to_wsgi osprofiler url_normalize request_id build_auth_context token_auth json_body ec2_extension s3_extension admin_service
[pipeline:api_v3]
# The last item in this pipeline must be service_v3 or an equivalent
# application. It cannot be a filter.
pipeline = healthcheck cors sizelimit http_proxy_to_wsgi osprofiler url_normalize request_id build_auth_context token_auth json_body ec2_extension_v3 s3_extension service_v3
##删除多的功能模块：admin_token_auth
2.7取消密码方式的登陆的环境变量
unset OS_AUTH_URL OS_PASSWORD
##改为token的方式
2.8获取admin的token
openstack --os-auth-url http://ctrl.blue.edu:35357/v3 \
--os-project-domain-name default \
--os-user-domain-name default \
--os-project-name admin \
--os-username admin token issue
ADMIN_PASS
2.9获取demo的token
openstack --os-auth-url http://ctrl.blue.edu:5000/v3 \
--os-project-domain-name default \
--os-user-domain-name default \
--os-project-name demo \
--os-username demo token issue
DEMO_PASS
2.10生成管理员获取token脚本
vim ~/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=ADMIN_PASS
export OS_AUTH_URL=http://ctrl.blue.edu:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
2.11普通用户获取token脚本
Vim ~/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=DEMO_PASS
export OS_AUTH_URL=http://ctrl.blue.edu:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
2.12执行脚本获取token
.admin-openrc
openstack token issue
.demo-openrc
openstack token issue
crtl节点glance配置
3.1执行脚本
