Hello,
I'd like to increase on centos queens the threads for openstack dashboard.
At this time my /etc/httpd/conf.d/openstack-dashboard.conf is the following:

WSGIDaemonProcess dashboard
WSGIProcessGroup dashboard
WSGISocketPrefix run/wsgi
WSGIApplicationGroup %{GLOBAL}
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>

I tired to modify the first line  like this:
WSGIDaemonProcess dashboard user=apache group=apache processes=3 threads=10
I restartded httpd but now I am not able to log on the the dashboard.
I am sure keystone is working because I am able do execute all commands with command line.
Any help, please ?
Regards
Ignazio
