openstack（queens版本）安装（二）：安装keystone服务

keystone服务安装在controller节点上，通过restful接口为其它节点提供认证。

1.创建数据库

CREATE DATABASE keystone；
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY 'KEYSTONE_DBPASS';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY 'KEYSTONE_DBPASS';
FLUSH PRIVILEGES;

2.安装并配置相关组件

安装组件

yum -y install openstack-keystone httpd mod_wsgi

配置/etc/keystone/keystone.conf

[default]
admin_token = ADMIN_TOEKN

[database]
# ...
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone
....
[token]
# ...
provider = fernet

数据库初始化

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

初始化Fernet key

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

配置httpd服务

#配置/etc/httpd/conf/httpd.conf,修改ServerName

ServerName controller

#设置wsgi配置/usr/share/keystone/wsgi-keystone.conf

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

#启动服务

systemctl enable httpd.service
systemctl start httpd.service

#设置环境变量

export OS_TOKEN=ADMIN_TOKEN
export OS_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3

source /opt/adminrc

3.创建domain，project，user，role

$ openstack domain create --description "An Example Domain" example

| name        | service                          |
| parent_id   | default                          |
+-------------+----------------------------------+

$ openstack project create --domain default  --description "Demo Project" demo
+-------------+----------------------------------+

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://controller:5000/v3
export OS_IMAGE_API_VERSION=2
export OS_IDENTITY_API_VERSION=3

修改/root/.bashrc添加 source /opt/admin-openrc
