How to keep logs longer with less space and logrotate.conf configuration

  
 

 
 Normally logs rotate monthly, over writing all the old data.  Here's a
  sample "/etc/logrotate.conf" that will keep 12 months of backup
  compressing the logfiles

    $ cat /etc/logrotate.conf

          # see "man logrotate" for details
          # rotate log files weekly
          #chirico changes to monthly
          monthly

          # keep 4 weeks worth of backlogs
          # keep 12 months of backup
          rotate 12

          # create new (empty) log files after rotating old ones
          create

          # uncomment this if you want your log files compressed
          compress

          # RPM packages drop log rotation information into this directory
          include /etc/logrotate.d

          # no packages own wtmp -- we'll rotate them here
          /var/log/wtmp {
              monthly
              create 0664 root utmp
              rotate 1
          }

          # system-specific logs may be also be configured here.
