1.dashboard打不开

编辑：/etc/httpd/conf.d/openstack-dashboard.conf
在WSGISocketPrefix run/wsgi下面加一行代码：
WSGIApplicationGroup %{GLOBAL}
保存，重启httpd服务。

2.无法创建虚机，nova-conductor.log提示domaintype=kvm

修改nova.conf，加入：

compute_driver = libvirt.LibvirtDriver
 
[libvirt]
virt_type = qemu

3.cinder问题

安装使用链接
https://docs.openstack.org/cinder/latest/install/cinder-controller-install-obs.html
3.1 需要注意各个服务在mysql里面配置的密码是否正确

mysql -u cinder -p

3.2 如果数据库为空，使用命令初始化
cinder-manage db sync

osadmin@controller:/tmp$ mysql -u cinder -p
Enter password:

4.添加白名单

neutron port-list
neutron port-update 90c7ef65-cbd1-4047-9d42-859042dfa836  --allowed-address-pairs type=dict list=true ip_address=192.168.2.244
