logrotate

Log production.log increase little by little after you application is deployed in production environment.

If you want to maintain production log on CentOS, Debian, Ubuntu and Fedora, it is easy to use logrotate.

cd ~/webapp
mkdir logrotate
cd logrotate
vi logrotate.conf

The following setting is one example. Current log is copied to other file once per week. Logs before 12 weeks are deleted.

/home/ken/webapp/log/production.log {
  weekly
  copytruncate
  rotate 12
  missingok
}

Let's register the command which execute rotation to crontab.

crontab -e

You write the following setting.

0 0 * * * /usr/sbin/logrotate -s $HOME/webapp/logrotate/logrotate.status $HOME/webapp/logrotate/logrotate.conf
