Logrotate

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:

/home/haiwen/logs/seafile.log
{
daily
missingok
rotate 15
compress
delaycompress
notifempty
sharedscripts
postrotate
[ ! -f /home/haiwen/pids/seaf-server.pid ] || kill -USR1 `cat /home/haiwen/pids/seaf-server.pid`
endscript
}
/home/haiwen/logs/ccnet.log
{
daily
missingok
rotate 15
compress
delaycompress
notifempty
sharedscripts
postrotate
[ ! -f /home/haiwen/pids/ccnet.pid ] || kill -USR1 `cat /home/haiwen/pids/ccnet.pid`
endscript
}
/home/haiwen/logs/index.log
{
monthly
missingok
rotate 15
compress
delaycompress
notifempty
sharedscripts
}

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