====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)

=======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
