　　====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)

　　Unable to establish connection to http://controller:9696/v2.0/agents.json


　　=======解决方案===
　　问题一的解决方案：



1 ]# netstat -anp|grep 35357        //使用命令查看是否有这个服务端口
2
3
4
5 如果没有35357 端口
6 ]# vim /etc/keystone/keystone.conf
7
8 admin_port = 35357                //取消注释
9
10
11
12 重启keystone服务
13 在kilo中 keystone 服务名称为openstack-keystone.service
14 ]# systemctl enable openstack-keystone.service  && systemctl restart openstack-keystone.service

36 问题一解决
　　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.

　　问题三的解决方案：



1 查看9696端口：
2
3 ]# netstat -anp|grep 9696
4
5 如果没有端口开启，查看下面配置文件
6
7 ]# vim /etc/neutron/neutron.conf
8 bind_port = 9696         
9
10 重启neutron服务
11
12 ]# systemctl restart neutron-server neutron-dhcp-agent neutron-l3-agent  neutron-metadata-agent  neutron-openvswitch-agent
13
14 ]# netstat -anp|grep 9696
15 tcp 0 0 0.0.0.0:9696 0.0.0.0:* LISTEN 11895/python2
