Overview
logrotate is a tool that is run periodically - by default, daily - by cron. Every tine it is executed, logrotate reads its configuration files and manages log files declared in those configuration files, according to the specified rules.
A log rotation consists in renaming the current log fie, so my.log becomes my.log.1, my.log.1 becomes my.log.2 and so forth, and setting up a new my.log log file. The number of log files to be retained is specified in the configuration. Additional operations like compression may be specified.

yum install -y logrotate
