#1、虛擬機網絡正常，網頁控制台報錯 "錯誤：無法連接到Neutron"
#查詢原因如下：
#Dashboard默認配置開啟了路由,而Neutron配置沒開啟，造成沖突

#解決辦法1
#Dashboard配置關閉路由，重啟http
#修改/etc/openstack-dashboard/local_settings配置'enable_router': True改為'enable_router': False
sed -i "s#'enable_router': True#'enable_router': False#" /etc/openstack-dashboard/local_settings
systemctl restart httpd.service

#解決辦法2
#Neutron配置開啟route，重啟Neutron服務
openstack-config --set /etc/neutron/neutron.conf DEFAULT service_plugins router
systemctl restart neutron-server.service
