MongoDB log is too large a workaround

MongoDB's log growth is fast,/Var space is immediately full, even if you change to another disk partition to save the log, the log is growing fast, the disk to see the chime.

A good way to do this is to use a rotational log.

MongoDB rotation Log a bit strange , the Linux mongd service accepts a KILL-SGIUSR1 command immediately renames the current log file to a file with a date, and then creates a new log file.

You can configure a rotation policy if you do not want a general rotation log. However, after testing, sending the command will not affect MongoDB's service.

Here is an example of finding the process ID and then sending the command.

[Email protected]:/etc/init.d# ps-def | grep Mongod
MongoDB 723 1 May04? 6-22:23:53/usr/bin/mongod--config/etc/mongodb.conf
Root 22035 22012 0 20:22 pts/2 00:00:00 grep--color=auto Mongod
[Email protected]:/etc/init.d#KILL-SIGUSR1 723
[Email protected]:/etc/init.d# cd/home/mongodb/log/
[Email protected]:/home/mongodb/log# ls
Mongodb.log mongodb.log.2014-05-18t12-23-51
[Email protected]:/home/mongodb/log# Ls-alh

drwxrwxrwx 4 root root 4.0K Apr 20 21:25..
-rw-r--r--1 MongoDB nogroup 34K may 20:24 Mongodb.log
-RWXRWXRWX 1 MongoDB nogroup 20G may 20:23 mongodb.log.2014-05-18t12-23-51

Official documents:

http://docs.mongodb.org/manual/tutorial/rotate-log-files/

You can now move or delete the log files for the previous 20G.

You can also make a regular script on your own and send commands to the Mongod service regularly.
