Enable automatic logrotation MOngodb

HI There,

this document will help to enable automatic logrotate for mongod instance.


Manually you can rotate the logfile as below

    > use admin
    > db.runCommand( { logRotate : 1 } )

For automating it, follow below

Go to directory  /etc/logrotate.d

vi mongodb

--add below to mongodb file

++++++++++++++++++++++++++++++++++++++++++++++++

/var/log/mongodb/mongod.log

{

   rotate 7

   daily

   size 1M

   missingok

   create 0600 mongod mongod

   delaycompress

   compress

   sharedscripts

   postrotate

     /bin/kill -SIGUSR1 $(cat /var/run/mongodb/mongod.pid)

   endscript

}

+++++++++++++++++++++++++++++++++++++++++++++++++++

'Daily' means that logs are rotated every day, 

'rotate 30' - logs will be kept for 30 days before being sent via email or deleted, 

'compress' - old logs are compressed with gzip, 

'missingok' - skip any errors in any log file is missing, 

'sharedscript's - scripts that are run script once, 

'postrotate' and 'endscript' - execute script after log rotation.

Note: In above script

"/var/log/mongodb/mongod.log" --- Should be replaced by your logfile 

To test if logrotate is working use below

logrotate --force /etc/logrotate.d/mongodb

Thanks
