[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

    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

    ErrorLog /var/log/httpd/keystone-error.log
    CustomLog /var/log/httpd/keystone-access.log combined

   
        Require all granted
   

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 

# openstack endpoint create --region RegionOne \
  volumev2 admin 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

1.7.4 启动cinder服务
# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service

192.168.0.230 controller

####################配置ceph存储后端#################################
1.1 创建pools
# ceph osd pool create volumes 128
# ceph osd pool create images 128
# ceph osd pool create backups 128
# ceph osd pool create vms 128

1.2 安装ceph包
# yum install ceph-common

~~~~~如果此节点没有ceph配置，需拷贝ceph.conf~~~~~~~~~~
1.3 创建cephx用户
# ceph auth get-or-create client.cinder mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=volumes, allow rwx pool=vms, allow rwx pool=images'

1.4 创建本地配置
# ceph auth get-or-create client.cinder | sudo tee /etc/ceph/ceph.client.cinder.keyring
# ceph auth get-key client.cinder | tee client.cinder.key

1.5 创建secret-key(计算节点ovirt需要)
# uuidgen
457eb676-33da-42ec-9a8c-9293d545c337

# cat > secret.xml <
  457eb676-33da-42ec-9a8c-9293d545c337
 
    client.cinder 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

1.6 修改cinder.conf
# vi /etc/cinder/cinder.conf 
[DEFAULT]
enabled_backends = ceph

[ceph]
volume_driver = cinder.volume.drivers.rbd.RBDDriver
volume_backend_name = ceph
rbd_pool = volumes
rbd_ceph_conf = /etc/ceph/ceph.conf
rbd_flatten_volume_from_snapshot = false
rbd_max_clone_depth = 5
rbd_store_chunk_size = 4
rados_connect_timeout = -1
glance_api_version = 2
rbd_user = cinder
rbd_secret_uuid = 457eb676-33da-42ec-9a8c-9293d545c337

# 1.7 启动cinder-volume服务
# systemctl enable openstack-cinder-volume.service target.service
# systemctl start openstack-cinder-volume.service target.service
