Package: nginx-common Version: 0.8.54-3 Severity: important Recently I noticed that logrotate does not actually rotate the files correctly. I noticed this in 0.8.54-3 and is an issue in what will be 0.8.54-4.
The issue seems to be that neither -USR1 or -s reopen will reopen the log files after they've been rotated. I'm not sure if this specific to the version packaged in Debian but I've seen it as an issue on both Ubuntu and Debian. Below is what I tried to do to figure out what's going on... ### Clean slate root@liber:/var/log/nginx# /etc/init.d/nginx stop Stopping nginx: nginx. root@liber:/var/log/nginx# rm * ### Start Nginx: Creates new log files root@liber:/var/log/nginx# /etc/init.d/nginx start Starting nginx: nginx. root@liber:/var/log/nginx# du access.log access.log.1 8 access.log du: cannot access `access.log.1': No such file or directory ### Force logrotate to run (which runs the kill -USR1) root@liber:/var/log/nginx# logrotate -f /etc/logrotate.d/nginx ### Log files rotated root@liber:/var/log/nginx# du access.log access.log.1 0 access.log 8 access.log.1 ### At this point files should already be getting written to the new file ### because of the -USR1 in the logrotate script root@liber:/var/log/nginx# du access.log access.log.1 0 access.log 24 access.log.1 ### To make sure the kill was run, we invoke it ourselves root@liber:/var/log/nginx# kill -USR1 `cat /var/run/nginx.pid` ### And see that nginx still isn't using the new file root@liber:/var/log/nginx# du access.log access.log.1 0 access.log 48 access.log.1 ### Using the more proper approach root@liber:/var/log/nginx# nginx -s reopen ### We get the same thing root@liber:/var/log/nginx# du access.log access.log.1 0 access.log 68 access.log.1 ### Trying a less appropriate option.... root@liber:/var/log/nginx# /etc/init.d/nginx reload Reloading nginx configuration: nginx. ### It's finally reopened the files root@liber:/var/log/nginx# du access.log access.log.1 20 access.log 68 access.log.1 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
