로그 관리를 위한 logrotate.d

logrotate  is  designed to ease administration of systems that generate
       large numbers of log files.  It allows automatic rotation, compression,
       removal, and mailing of log files.  Each log file may be handled daily,
       weekly, monthly, or when it grows too large.

로그파일이 너무 많아져서 30% 정도의 디스크 용량을 사용하고 있었다.

일정한 주기로 불필요한 많은 양의 로그 파일을 관리에 logrotate command가 있어 활용하였다.

-v     Turn on verbose mode.


       -d     Turns  on  debug mode and implies -v.  In debug mode, no changes
              will be made to the logs or to the logrotate state file.


       -f, --force
              Tells logrotate to force the rotation, even if it doesn’t  think
              this  is  necessary.   Sometimes this is useful after adding new
              entries to logrotate, or if old log files have been  removed  by
              hand,  as  the  new files will be created, and logging will con-
              tinue correctly.


       -m, --mail <command>
              Tells logrotate which command to use  when  mailing  logs.  This
              command  should accept two arguments: 1) the subject of the mes-
              sage, and 2) the recipient. The command must then read a message
              on standard input and mail it to the recipient. The default mail
              command is /bin/mail -s.


       -s, --state <statefile>
              Tells logrotate to use an alternate state file.  This is  useful
              if  logrotate  is being run as a different user for various sets
              of log files.  The default state file is /var/lib/logrotate/sta-
              tus.


       --usage
              Prints a short usage message.

 다음과 같은 옵션이 있는데, 훑어보면 되겠다.

/etc/logrotate.d 

ex) compress_log

$logpath/*.log {

        copytruncate // copy 파일을 생성한 후에 원래의 로그 파일들을 truncate한다

        daily

        rotate 365

        missingok

        compress<!-- 오래된 로그파일을 압축 (default : gzip) -->

}

$ logrotate -d /etc/logrotate.d/compress_log

$ logrotate -f /etc/logrotate.d/compress_log (강제로 실행)
