问题点：

安装完pike后发现只能使用 ip:80 登录到http的主页面不能使用 http://controller_ip:80/dashboard 登录openstack登录页面。如下图

重启httpd 服务

systemctl restart httpd

查看日志 /var/log/httpd/error_log

 [core:error] [pid 3285] [client 192.168.70.1:49887] End of script output before headers: django.wsgi
 [autoindex:error] [pid 3481] [client 192.168.70.1:52306] 
AH01276: Cannot serve directory /var/www/html/: No matching DirectoryIndex (index.html) found, 
and server-generated directory index forbidden by Options directive

查了一下这个horizon的一个bug：

具体解决方法：

fix bug:
Resolvent：

../httpd/conf.d/openstack-dashboard.conf

add a line:
-------------------------------------
WSGIDaemonProcess dashboard
WSGIProcessGroup dashboard
WSGISocketPrefix run/wsgi
WSGIApplicationGroup %{GLOBAL}                     <======== add a line

WSGIScriptAlias /dashboard /usr/share/openstack-dashboard/openstack_dashboard/wsgi/django.wsgi
Alias /dashboard/static /usr/share/openstack-dashboard/static

<Directory /usr/share/openstack-dashboard/openstack_dashboard/wsgi>
  Options All
  AllowOverride All
  Require all granted
</Directory>

<Directory /usr/share/openstack-dashboard/static>
  Options All
  AllowOverride All
  Require all granted
</Directory>
-------------------------------------
systemctl restart httpd

Because there is no time to look at the code, give the solution for the time being
