====环境==
openstack ：kilo
CentOS ： 7
====问题===
在没有关vm的情况下，重启了controller。
问题一：
在使用nova service-list 或者openstack-status的时候或者其他认证需求的时候出现以下错误
ERROR: openstack Unable to establish connection to http://controller:35357/v3/auth/tokens
ConnectionRefused: Unable to establish connection to http://controller:35357/v3/auth/tokens

问题二：
解决问题一之后发现dashboard无法正常启动了：
ImportError: Could not import settings 'openstack_dashboard.settings' (Is it on sys.path? Is there an import error in the settings file?): No module named main

openstack-dashboard也出现了变化

问题三：
使用nova boot 创建vm的时候出现错误：
1 ERROR (ClientException): The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-2f5571f4-aa54-4d45-a096-cb8797c5ff7a) 2 3 ConnectionRefused: Unable to establish connection to http://controller:9696/v2.0/ports.json?tenant_id=

问题二的解决方案：
I have resolved the "openstack service create" problem following this steps : HTTP and KEYSTONE service sharing the same port, so stop httpd and start openstack-keystone.service. Edit /etc/keystone/keystone.conf and replace "hostname or ip" to "localhost": connection = mysql://keystone:openstack@localhost/keystone Remember to stop service httpd and enable start service keystone: - systemctl stop httpd.service - systemctl enable openstack-keystone.service => systemctl start openstack-keystone.service And finally, exec "openstack service create --name keystone --description "OpenStack Identity" identity" command. Most important to remember, the dashboard horizon use apache so that keystone and apache service must be running. Into keystone.conf and wsgi-keystone.conf occur bind a single interface on ports 5000 and 35357 instead of all interface "*" or "0.0.0.0": edit /etc/keystone/keystone.conf => set admin_bind_host = <ip_mgmt> => set public_bind_host = <ip_mgmt> edit /etc/httpd/conf.d/wsgi-keystone.conf => set Listen 127.0.0.1:5000 => Listen 127.0.0.1:35357 => same for VirtualHost 127.0.0.1:5000 & 35357 After service openstack-keystone.service and httpd.service restart, both process will be running in the same time. 参考源网址：
