Few Logrotate Configs

Engineering Jan 18, 2018

Logrotate is a linux utility which rotates files upon certain conditions.If it's not installed, you can do via apt-get install logrotate or yum install logrotate

The usual tricky part of logrotate is to reload the process when rotation is complete.

Here I'm storing a few logrotate configurations which are useful for me. Hope they're useful for you too.

NOTE: You should change paths appropriately. All the files go in /etc/logrotate.d/

Mongodb

/var/log/mongodb/*.log {
    daily
    size 100M
    rotate 1
    compress
    dateext
    missingok
    notifempty
    sharedscripts
    copytruncate
    postrotate
        /bin/kill -SIGUSR1 `cat /vol/mongo/mongod.lock 2> /dev/null` 2> /dev/null || true
    endscript
}

Other examples:

/var/logs/randomdump.log 
{
   size 100k
   copytruncate
   rotate 0
}
#The above config will rotate the file every 100kb, truncates the log file and deletes the rotated file.

/var/logs/access.log
{
   size 100k
   copytruncate
   rotate 7
}

/var/log/postgresql/*.log {
       weekly
       rotate 10
       copytruncate
       delaycompress
       compress
       notifempty
       missingok
       su root root
}
