Chuẩn bị

Tạo database và phân quyền cho user keystone

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';

Cài đặt và cấu hình

Cài packages

# yum install openstack-keystone httpd mod_wsgi

Cấu hình keystone

/etc/keystone/keystone.conf
[database]
connection = mysql+pymysql://keystone:[email protected]/keystone
[token]
provider = fernet

Khởi tạo database

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

Khởi tạo Fernet key repository

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

Khởi tạo dịch vụ Keystone

# keystone-manage bootstrap --bootstrap-password ADMIN_PASS \
--bootstrap-admin-url http://controller:35357/v3/ \
--bootstrap-internal-url http://controller:5000/v3/ \
--bootstrap-public-url http://controller:5000/v3/ \
--bootstrap-region-id RegionOne

Cấu hình Apache để phục vụ API

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

Start dịch vụ

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

Khởi tạo console admin

$ 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:35357/v3
$ export OS_IDENTITY_API_VERSION=3
