after installed openstack by devstack , i can not find where is the logs of nova,neturon,keystone ....etc....

there is no directory like /var/logs/nova or /var/logs/neutron....

after i google the problem .i add SYSLOG=True SYSLOG_HOST=$HOST_IP  SYSLOG_PORT=516 in

the localrc ,then rerun the devstack ,but still no logs in syslog..

btw, i cannot run the command like service openstack-nova-compute restart ,because there is no bash script about openstack services in /etc/init.d how can i restart the services after edit these .conf .

 thx everyone...

In devstack, logs of openstack services are attached with linux screens. you can find them by running following command

screen -x stack

you can traverse forward through screens by pressing CTRL a n and backwards with CTRL a p

to restart a particular service, go to the relevant screen, press CTRL c (it will kill the process) and rerun the last command ( press up Arrow then Enter )

When you don't get an overview, do this first:

sudo chown stack:stack `readlink /proc/self/fd/0`

Then screen -x stack will work!

Also if you want logs to be redirected to some files, the log destination has to be configured before you run the ./

You should have added the entry SCREEN_LOGDIR=${DEST}/logs/screen

in the localrc or local.conf
