I think you should remove the line: sleep 15
It doesnt' anything useful, It just delay the restart, so during 15 seconds the request will end been registered in the old log file mv /mnt/vg0-lv0/access.log /mnt/vg0-lv0/access.log.OLD sudo kill -USR1 `cat /var/run/nginx.pid` sleep 2 head -n 5 /mnt/vg0-lv0/access.log If I would do this in a interactive way, I'd prefer mv /mnt/vg0-lv0/access.log /mnt/vg0-lv0/access.log.OLD sudo kill -USR1 `cat /var/run/nginx.pid` sleep 2 tail -f /mnt/vg0-lv0/access.log because I see the log request in real time On Thu, Oct 2, 2014 at 8:39 AM, Igor Sysoev <[email protected]> wrote: > > On 02 Oct 2014, at 01:30, jmobile <[email protected]> wrote: > > > Hi, > > > > I'd like to check how nginx handles command from > > http://wiki.nginx.org/LogRotation > > kill -USR1 `cat /var/run/nginx.pid` > > > > I'm using it to recreate log files during rotation. > > > > My question if any loglines can be lost in case time interval between > > physical log files rotation and USR1 is large enough, like seconds?
