Hello, I tried :

Thanks for your answer.

I tried :

~$ sudo systemctl status devstack@keystone ● devstack@keystone.service - Devstack devstack@keystone.service Loaded: loaded (/etc/systemd/system/devstack@keystone.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since mer. 2017-05-10 09:18:29 CEST; 9min ago Process: 815 ExecStart=/usr/local/bin/uwsgi --ini /etc/keystone/keystone-uwsgi-public.ini (code=exited, status=1/FAILURE) Main PID: 815 (code=exited, status=1/FAILURE) Status: "initializing uWSGI"

And then, i tried to restart :

~$ sudo systemctl start devstack@keystone Job for devstack@keystone.service failed because the control process exited with error code. See "systemctl status devstack@keystone.service" and "journalctl -xe" for details.

So, I should not reboot openstack server, otherwise it will fail ?

How could I restart ? Should I unstack, and then, stack ?
