Rotate the log files. On OS X, newsyslog is the preferred utility to do that. Set up a file like this in /etc/newsyslog.d/nginx.conf:

# logfilename          [owner:group]    mode count size when  flags [/pid_file] [sig_num]
/var/log/nginx.log     deceze:wheel     644  2     1024 *     J

    shoudn't a SIGUSR1 signal be sent to the nginx master process? Or this can be skipped because the log file is not deleted but set to empty?

  • @Paolo Good point, I cannot actually answer that with certainty. You probably should.

Building on @deceze's answer, here's an adapted version of Apple's Apache configuration for a Homebrew-installed nginx:

#logfilename                            [owner:group]  mode count  size   when  [flags]  [/pid_file]                       [sig_num]
/opt/homebrew/var/log/nginx/access.log  _nginx:_nginx  644  10     20480  *     Z        /opt/homebrew/var/run/nginx.pid   30

This is assuming you're running as user:group _nginx:_nginx. It sends the correct SIGUSR1 signal (30 on macOS) to nginx. Also changed to using gzip instead of bzip2.
