#1、虚拟机网络正常，网页控制台报错 "错误：无法连接到Neutron"
#查询原因如下：
#Dashboard默认配置开启了路由,而Neutron配置没开启，造成冲突

#解决办法1
#Dashboard配置关闭路由，重启http
#修改/etc/openstack-dashboard/local_settings配置'enable_router': True改为'enable_router': False
sed -i "s#'enable_router': True#'enable_router': False#" /etc/openstack-dashboard/local_settings
systemctl restart httpd.service

#解决办法2
#Neutron配置开启route，重启Neutron服务
openstack-config --set /etc/neutron/neutron.conf DEFAULT service_plugins router
systemctl restart neutron-server.service
