openstack登陆dashboard界面认证错误

openstack打开dashboard界面登陆的时候显示认证错误，已确定域账户密码都是对的

解决方案：

先查看日志文件：

首先查看keystone的日志

2019-04-03 13:51:36.969 11355 INFO keystone.token.providers.fernet.utils [req-76bb2d23-6fb6-4386-a573-9649962bbbdf - - - - -] Loaded 2 encryption keys (max_active_keys=3) from: /etc/keystone/fernet-keys/

keystone认证一切正常

再去看下http的报错日志

[Wed Apr 03 13:54:47.543826 2019] [core:notice] [pid 12469] AH00094: Command line: '/usr/sbin/httpd -D FOREGROUND'
[Wed Apr 03 17:55:26.923891 2019] [:error] [pid 12471] Could not process panel theme_preview: Dashboard with slug "developer" is not registered.
[Wed Apr 03 17:55:27.732959 2019] [:error] [pid 12471] Logging out user "".
[Wed Apr 03 17:55:34.724240 2019] [:error] [pid 12471] Login failed for user "admin".

看来是dashboard配置文件出错了导致dashboard无法认证用户登录

检查/etc/openstack-dashboard/local_settings 配置文件

OPENSTACK_HOST字段未填写

OPENSTACK_HOST = "controller"

保存退出并重启http服务和缓存服务

systemctl restart httpd.service memcached.service

刷新页面重新登录

成功登陆。
