Hi,
I am trying to run UWSGI in emperor mode (for the first time in my life)
and i am having some issues in getting the vassals to spawn when uwsgi is
running with "--daemonize2". It works just fine with "--daemonize" but i
would really rather use "--daemonize2" for reasons outside of the scope of
this help request :)
UWSGI version is 1.4.8
My issue is that when UWSGI is started with --daemonize2 the uwsgi daemon
does not spawn any vassal until i SIGTERM it, when I do then it seems to
behave as expected, it finds the vassal and spawn the processes.
for example:
[root@mybox]# service uwsgi start
[root@mybox]# ps auxww | grep uwsgi
nobody 13075 0.0 0.0 19364 780 ? S 10:36 0:00
/usr/sbin/uwsgi --logto /var/log/uwsgi/error.log --daemonize2
/var/log/uwsgi/error.log --logfile-chmod 644 --logfile-chown --pidfile2
/var/run/uwsgi/uwsgi.pid --stats /var/run/uwsgi/uwsgi.stats --zerg-server
/var/run/uwsgi/uwsgi.zerg --need-app --ini /etc/uwsgi/uwsgi.ini
[root@mybox]#
Then i SIGTERM it
[root@mybox]# kill 13075
[root@mybox]# ps auxww | grep uwsgi
nobody 13075 0.0 0.0 18940 1480 ? S 10:36 0:00
/usr/sbin/uwsgi --logto /var/log/uwsgi/error.log --daemonize2

[uWSGI] getting INI configuration from /etc/uwsgi/vassals/test.ini
Mon Oct 21 11:08:23 2013 - [emperor] vassal /etc/uwsgi/vassals/test.ini is
now loyal
Mon Oct 21 11:08:23 2013 - [emperor] vassal /etc/uwsgi/vassals/test.ini is
now loyal
When i start it with just "--daemonize" this all happen at startup and
everything works.
Is there anything i can do (or i am doing wrong) to get it to work with
"--daemonize2" ?
Thanks
Francesco
