OpenStack-train版安装之安装Keystone（认证服务）、Glance（镜像服务）、Placement

安装Keystone（认证服务）

1. 数据库创建、创建用户并授权

 # mysql

MariaDB [(none)]> CREATE DATABASE keystone;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY 'KEYSTONE_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \IDENTIFIED BY 'KEYSTONE_DBPASS';

2. 安装和配置

 # yum install openstack-keystone httpd mod_wsgi -y

配置，修改配置文件/etc/keystone/keystone.conf，在对应分组【[组名]】下添加配置：
[database]
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone
[token]
provider = fernet

初始化数据库：

 # su -s /bin/sh -c "keystone-manage db_sync" keystone

初始化密钥库：

# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

引导认证服务：

# keystone-manage bootstrap --bootstrap-password ADMIN_PASS \--bootstrap-admin-url http://controller:5000/v3/ \--bootstrap-internal-url http://controller:5000/v3/ \--bootstrap-public-url http://controller:5000/v3/ \--bootstrap-region-id RegionOne

配置，修改配置文件/etc/httpd/conf/httpd.conf，在配置ServerAdmin root@localhost下一行添加ServerName controller：

创建软链：

# ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/

设置开机启动并启动服务：

# systemctl enable httpd.service
# systemctl start httpd.service

验证

# systemctl status httpd.service
# lsof -i:5000

3. 创建OpenStack客户端环境脚本

# mkdir -p /root/.openstack

# cat >> /root/.openstack/admin-openrc << EOF
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:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
EOF

加入环境变量，生效：

# cat >> /root/.bashrc << EOF
source  /root/.openstack/admin-openrc
EOF
# source /root/.bashrc

4. 验证
   可正常查询：

# openstack token issue

验证auth_url返回报文：

# curl controller:5000/v3

5. 创建域、项目、用户、角色

# openstack domain create --description "An Example Domain" example
# openstack project create --domain default   --description "Service Project" service
# openstack project create --domain default   --description "Demo Project" myproject
# openstack user create --domain default   --password-prompt myuser

输入用户密码、确认密码：MYUSER_PASS
创建角色、将用户加入角色：

# openstack role create myrole
# openstack role add --project myproject --user myuser myrole

6. 说明

• 详细说明参考官网：
  https://docs.openstack.org/keystone/train/install/keystone-install-rdo.html
• 安装mysql时做了安装初始化，将密码设置为无，如有设置密码，连接时请加账号密码。
• OpenStack部署完成后使用，dashboard中使用角色管理时提示【错误:在keystone中无法找到默认角色user】。解决方法一：创建user角色:openstack role create user。解决方法二：安装Horizon配置‘OPENSTACK_KEYSTONE_DEFAULT_ROLE = “user”’将user改为其他已存在的角色。

安装Glance（镜像服务）

1. 数据库创建、创建用户并授权

# mysql

MariaDB [(none)]> CREATE DATABASE glance;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
IDENTIFIED BY 'GLANCE_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \IDENTIFIED BY 'GLANCE_DBPASS';

2. 创建服务凭证

 # openstack user create --domain default --password-prompt glance

输入密码：GLANCE_PASS
确认密码：GLANCE_PASS

# openstack role add --project service --user glance admin# openstack service create --name glance   --description "OpenStack Image" image

3. 创建服务API接入点

# openstack endpoint create --region RegionOne   image public http://controller:9292
# openstack endpoint create --region RegionOne   image internal http://controller:9292
# openstack endpoint create --region RegionOne   image admin http://controller:9292

4. 安装和配置

# yum install openstack-glance -y

配置，修改配置文件/etc/glance/glance-api.conf，在对应分组【[组名]】下添加配置：
[database]
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance
password = GLANCE_PASS
[paste_deploy]
flavor = keystone
[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/

初始化数据库：

# su -s /bin/sh -c "glance-manage db_sync" glance

设置开机启动并启动服务：

# systemctl enable openstack-glance-api.service
# systemctl start openstack-glance-api.service

5. 验证
   公网下载镜像（下载失败可直接使用浏览器下载）：

# wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img

上传镜像到glance服务：

# glance image-create --name "cirros"   --file cirros-0.4.0-x86_64-disk.img   --disk-format qcow2 --container-format bare   --visibility public

查看镜像列表：

# glance image-list

或者

# openstack image list

验证镜像服务的接入点：

#curl controller:9292

IDENTIFIED BY 'PLACEMENT_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' \IDENTIFIED BY 'PLACEMENT_DBPASS';

2. 创建服务凭证

# openstack user create --domain default --password-prompt placement

输入密码：PLACEMENT_PASS
确认密码：PLACEMENT_PASS

# openstack role add --project service --user placement admin# openstack service create --name placement   --description "Placement API" placement

3. 创建服务API接入点

# openstack endpoint create --region RegionOne   placement public http://controller:8778
# openstack endpoint create --region RegionOne   placement internal http://controller:8778
# openstack endpoint create --region RegionOne   placement admin http://controller:8778

4. 安装和配置

# yum install openstack-placement-api -y

[placement_database]
connection = mysql+pymysql://placement:PLACEMENT_DBPASS@controller/placement
[api]
auth_strategy = keystone
[keystone_authtoken]
auth_url = http://controller:5000/v3
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = placement
password = PLACEMENT_PASS

配置，修改配置文件/etc/httpd/conf.d/00-placement-api.conf，添加配置：

<IfVersion < 2.4>
Order allow,deny
Allow from all

# placement-status upgrade check

验证接入点：

# curl controller:8778
