#################### 以上部分为 openstack 基本环境要求 #######################

####################openstack 认证服务环境 ################################
1. 安装与配置
1.1 创建 keystone 数据库
# mysql -u root -p
# CREATE DATABASE keystone;
1.2 数据库授权
# GRANT ALL PRIVILEGES ON keystone.* TO keystone @ localhost \
IDENTIFIED BY KEYSTONE_DBPASS
GRANT ALL PRIVILEGES ON keystone.* TO keystone @ % \
IDENTIFIED BY KEYSTONE_DBPASS
1.3 生成一个随机值在初始的配置中作为管理员的令牌
# openssl rand -hex 10
1cc14ab18f01e6e33a2a

1.4 安装 keystone 相关包
# yum install openstack-keystone httpd mod_wsgi

1.5 修改 keystone 配置
vim /etc/keystone/keystone.conf
[DEFAULT]
admin_token = 1cc14ab18f01e6e33a2a
[database]
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone
[token]
provider = fernet

1.6 初始化身份认证服务的数据库
# su -s /bin/sh -c keystone-manage db_sync keystone

1.7 初始化 Fernet keys
# keystone-manage fernet_setup –keystone-user keystone –keystone-group keystone

1.8 配置 Apache HTTP 服务器

# vim /etc/httpd/conf/httpd.conf
ServerName controller

1.9 创建 wsgi-keystone.conf
# vim /etc/httpd/conf.d/wsgi-keystone.conf

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

/VirtualHost

1.10 关闭 selinux
# setenforce 0
1.11 配置 hosts
# vim /etc/hosts
192.168.0.230 controller

1.11 启动 apache 服务
# systemctl enable httpd.service
# systemctl start httpd.service

2 创建服务实体和 API 端点
2.1 配置环境变量
# export OS_TOKEN=1cc14ab18f01e6e33a2a
# export OS_URL=http://controller:35357/v3
# export OS_IDENTITY_API_VERSION=3

2.2 创建服务实体和 API 端点
2.2.1 创建服务实体和身份认证服务：
# openstack service create \
–name keystone –description OpenStack Identity identity

2.2.2 创建认证服务的 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

3 创建域、项目、用户和角色
3.1 创建域 “default“：
# openstack domain create –description Default Domain default

3.2 创建管理的项目、用户和角色

# 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

4. 验证操作

4.1 因为安全性的原因，关闭临时认证令牌机制：
编辑 /etc/keystone/keystone-paste.ini 文件，从 “[pipeline:public_api]“，[pipeline:admin_api]“ 和 “[pipeline:api_v3]“ 部分删除 “admin_token_auth。

重置 “OS_TOKEN“ 和 “OS_URL“ 环境变量：
# unset OS_TOKEN OS_URL

作为 admin 用户，请求认证令牌：
# 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

5 创建 OpenStack 客户端环境脚本
# 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://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

验证:
# . admin-openrc
# openstack token issue

################################openstack 块存储服务配置 #####################
1 openstack 块存储服务配置
1.1 创建 cinder 数据库
# mysql -u root -p
CREATE DATABASE cinder;

1.2 数据库授权
# GRANT ALL PRIVILEGES ON cinder.* TO cinder @ localhost \
IDENTIFIED BY CINDER_DBPASS
GRANT ALL PRIVILEGES ON cinder.* TO cinder @ % \
IDENTIFIED BY CINDER_DBPASS

1.3 获得 admin 凭证来获取只有管理员能执行的命令的访问权限
# . admin-openrc

要创建服务证书，完成这些步骤
1.4 创建 cinder 用户
# openstack user create –domain default –password-prompt cinder
# openstack role add –project admin –user cinder admin

1.5 创建 cinder 和 cinderv2 服务实体：
# openstack service create –name cinder \
–description OpenStack Block Storage volume
# openstack service create –name cinderv2 \
–description OpenStack Block Storage volumev2

1.6 创建块存储 api 入口
# openstack endpoint create –region RegionOne \
volume public http://controller:8776/v1/%$tenant_id$s

# openstack endpoint create –region RegionOne \
volume internal http://controller:8776/v1/%$tenant_id$s

# openstack endpoint create –region RegionOne \
volume admin http://controller:8776/v1/%$tenant_id$s

# openstack endpoint create –region RegionOne \
volumev2 public http://controller:8776/v2/%$tenant_id$s

# openstack endpoint create –region RegionOne \
volumev2 internal http://controller:8776/v2/%$tenant_id$s

1.7 cinder 安装并配置组件
1.7.1 安装包
# yum install openstack-cinder

1.7.2 设置 cinder.conf
# vim /etc/cinder/cinder.conf
[database]
connection = mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder

[DEFAULT]
rpc_backend = rabbit
auth_strategy = keystone
my_ip = 10.0.0.11

[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = admin
username = cinder
password = CINDER_PASS

[oslo_concurrency]

lock_path = /var/lib/cinder/tmp

说明：将 CINDER_PASS 替换为你在认证服务中为 cinder 用户选择的密码。
在 [DEFAULT 部分，配置 “my_ip“ 来使用控制节点的管理接口的 IP 地址。

1.7.3 初始化块设备服务的数据库
# su -s /bin/sh -c cinder-manage db sync cinder

457eb676-33da-42ec-9a8c-9293d545c337

# cat secret.xml EOF
secret ephemeral= no private= no
uuid 457eb676-33da-42ec-9a8c-9293d545c337 /uuid
usage type= ceph
name client.cinder secret /name
/usage
/secret
EOF
# sudo virsh secret-define –file secret.xml
Secret 457eb676-33da-42ec-9a8c-9293d545c337 created

#sudo virsh secret-set-value –secret 457eb676-33da-42ec-9a8c-9293d545c337 –base64 $(cat client.cinder.key) rm client.cinder.key secret.xml
