按照openstack官网安装，执行：

openstack project create --domain default \
  --description "Service Project" service

出现 ：

Missing value auth-url required for auth plugin password

[root@controller ~]# openstack project create --domain default \
>   --description "Service Project" service
Missing value auth-url required for auth plugin password

解决方法：

新建admin-openrc.sh（目录位置不重要，记住位置就行），内容如下，记得修改OS_PASSWORD的值，我的是123123

export OS_USERNAME=admin
export OS_PASSWORD=123123
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

source admin-openrc.sh

补充：清除export设置的环境变量

unset OS_USERNAME
unset OS_PASSWORD
unset OS_PROJECT_NAME
unset OS_USER_DOMAIN_NAME
unset OS_PROJECT_DOMAIN_NAME
unset OS_AUTH_URL
unset OS_IDENTITY_API_VERSION

查看环境变量

 env | grep OS
