标题: openstack pike dashboard仪表盘无法登陆
问题现象 :

浏览器输入 http://controller/dashboard 访问仪表盘无法登陆，提示“出错啦！
遇到异常情况，请刷新。如需帮助请联系管理员。”

/var/log/httpd/error_log 中一直报以下错误:
... ...

[Wed Nov 01 02:41:09.576741 2017] [mpm_prefork:notice] [pid 16278] AH00170: caught SIGWINCH, shutting down gracefully

解决办法:
更改dashboard的local_settings配置文件并重启httpd和memcached，刷新后可正常登陆。
