Set up logrotate for server

How it works

seaf-server, ccnet-server (since version 3.1) and seafile-controller (since version 6.0.8) support reopenning
logfiles by receiving a SIGUR1 signal.

This feature is very useful when you need cut logfiles while you don’t want
to shutdown the server. All you need to do now is cutting the logfile on the fly.

NOTE: signal is not supported by windows, so the feature is not available there.

Default logrotate configuration directory

For debian, the default directory for logrotate should be /etc/logrotate.d/

Sample configuration

Assuming your ccnet-server’s logfile is /home/haiwen/logs/ccnet.log and your
ccnet-server’s pidfile for ccnet-server is /home/haiwen/pids/ccnet.pid.

Assuming your seaf-server’s logfile is setup to /home/haiwen/logs/seafile.log and your
seaf-server’s pidfile for seaf-server is setup to /home/haiwen/pids/seaf-server.pid:

The configuration for logrotate could be like this:

  1. /home/haiwen/logs/seafile.log
  2. {
  3.         daily
  4.         missingok
  5.         rotate 15
  6.         compress
  7.         delaycompress
  8.         notifempty
  9.         sharedscripts
  10.         postrotate
  11.                 [ ! -f /home/haiwen/pids/seaf-server.pid ] || kill -USR1 `cat /home/haiwen/pids/seaf-server.pid`
  12.         endscript
  13. }
  15. /home/haiwen/logs/ccnet.log
  16. {
  17.         daily
  18.         missingok
  19.         rotate 15
  20.         compress
  21.         delaycompress
  22.         notifempty
  23.         sharedscripts
  24.         postrotate
  25.                 [ ! -f /home/haiwen/pids/ccnet.pid ] || kill -USR1 `cat /home/haiwen/pids/ccnet.pid`
  26.         endscript
  27. }
  29. /home/haiwen/logs/index.log
  30. {
  31.     monthly
  32.     missingok
  33.     rotate 15
  34.     compress
  35.     delaycompress
  36.     notifempty
  37.     sharedscripts
  38. }

You can save this file, in debian for example, at /etc/logrotate.d/seafile.
