keystone标准配置文件位置及优先规则

~/.keystone/
~/
/etc/keystone/
/etc/

也可以通过指定参数 --config-file 形式指定配置文件位置来配置keystone

安装依赖包，yum源先配置好

yum install -y python2-pip  python-devel openssl-devel mariadb-server mariadb-devel libxslt-devel  libudev-devel  libffi-devel  libvirt  qemu-kvm  virt-install python-numdisplay rabbitmq-server memcached python-memcached

安装keystone依赖包

 升级pip
 pip install --upgrade pip
 安装包分发工具
 pip install pbr
 升级安装six，newton要求six>=1.10.，默认的系统six模块不满足
 pip install six --upgrade
 安装keystone依赖
 pip install .
 安装keystone服务
 python setup.py install

安装其它依赖

pip install Mysql-python
pip install uwsgi
pip install pymysql

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

设置项目，用户，和角色

keystone-manage bootstrap命令通过指定对应的参数
创建用户 --bootstrap-username
创建项目 --bootstrap-project-name
创建角色 --bootstrap-role-name
 
同样的，也可以预定义系统环境变量
对应的变量名
OS_BOOTSTRAP_USERNAME
OS_BOOTSTRAP_PROJECT_NAME
OS_BOOTSTRAP_ROLE_NAME
 
对于创建用户是必须提供一个密码参数的，通过
--bootstrap-password 指定用户密码
同样也支持系统预定义变量
OS_BOOTSTRAP_PASSWORD
 
可选的参数
--bootstrap-public-url
--bootstrap-admin-url
--bootstrap-internal-url
以上参数通过指定不同的端点创建一个身份认证服务，同样如果有需要可以配置
--bootstrap-region-id
--bootstrap-service-name

执行命令至少需要指定的参数

keystone-manage bootstrap --bootstrap-password s3cr3t

完整的命令参数

keystone-manage bootstrap \
    --bootstrap-password s3cr3t \
    --bootstrap-username admin \
    --bootstrap-project-name admin \
    --bootstrap-role-name admin \
    --bootstrap-service-name keystone \
    --bootstrap-region-id RegionOne \
    --bootstrap-admin-url http://localhost:35357 \
    --bootstrap-public-url http://localhost:5000 \
    --bootstrap-internal-url http://localhost:5000

以上命令将会创建一个admin用户，角色为admin，在admin项目上，这个用户指定了一个认证密码，

⚠️ 这个用户和这个项目将被创建到default 域

通过命令验证

openstack project list --os-username admin --os-project-name admin \
    --os-user-domain-id default --os-project-domain-id default \
    --os-identity-api-version  --os-auth-url http://localhost:5000 \
    --os-password s3cr3t
