Use syslog option in redis config and logrotate.

There is no "best way", as Redis doesn't currently do log rotation.

If you are careful, you can replace the file handle with a debugger,
but it's nasty.

Redis also allows you to send logs out to syslog, which you can then
use to handle log storage, rotation, etc.

Hi,

I'll try to use the "syslog" option.

Thanks for all replies.

Hi Darvin,

since Redis is not log-intensive (there is no case where requests are
logged) it reopens the file *every time* it adds a log line.
This means that log rotation is very easy to perform as you don't need
to send any special signal to Redis.

Just move the file away with "mv" and a new one is generated by Redis
for the first log line.

Or you can use syslog as many said.

Would this be a good logrotate configuration for redis ?

/var/log/redis/*.log {

  rotate 7

  weekly

  dateext

  size=+1M

  compress

  notifempty

  missingok

  create 0660 redis redis

}
