OpenStack登入界面（dashboard）打不开，一直显示连接超时，图形界面登入后云主机和网络也创建不了一直报错。

dashboard界面报错

可以试着重启dashboard服务

#systemctl restart memcached.service

#service httpd restart

创建网络云主机也一直报错

（报错的图一般都是右上角出现红色字体的文字）

试着重启Neutron服务

#service openstack-nova-api restart
#service openstack-nova-scheduler restart
#service openstack-nova-conductor restart
#service neutron-server restart

再重启Nova服务（这里只重启部分）

#service openstack-nova-consoleauth restart
#service openstack-nova-novncproxy restart

然后就可以成功创建了

以上重启命令以编辑成脚本

#!/bin/bash
set -e
COLOR="\033[32m"
COLOREND="\033[0m"
COLOR1="\033[31m"
COLOREND1="\033[0m"
`systemctl restart memcached.service`  &&  echo -e "$COLOR restart memcached successful$COLOREND" || echo -e "$COLOR1 restart failed$COLOREND1"
