Learn how to use the Logrotate utility to set up automatic rotation, compression and deletion of log files in Linux

Log rotation is closing a log file and opening a new log file when the first file is considered to be complete. Log rotation is typically performed according to a schedule (e.g., hourly, daily, weekly) or when a log file reaches a certain size.

That’s where the logrotate command in Linux comes into play. logrotate will periodically take the current log files, rename them, optionally compress them, and generate a fresh file to which an application can continue sending its logs.

在 Linux 系統上大部分的系統記錄檔都會放在 /var/log 目錄以及子目錄中，但系統各種記錄檔的內容會持續累積，若沒有定期管理與清理，就會不斷增長，造成記錄檔過於龐大的問題。

Log rotation solves these problems by periodically archiving active log files and creating new ones for incoming entries. This process typically involves renaming the current log file (such as by adding a timestamp or number) and then starting a new file

Log rotation 是一个创建新日志文件和存档&删除旧文件以节省磁盘空间的过程。 例如：apport.log 变为 apport.log.1，并创建一个新的 apport.log 日志文件记录新的日志项。
