Log rotatation in Linux is so handy as its name implies, it rotates log files. If you have a look at the /var/log path you can see
some compressed files some files which ends with .1

/var/log/my-app.log {
     weekly
     rotate 4
     compress
     delaycompress
     missingok
     notifempty
     create 644 root root
 }

The location of log rotation configs is in /etc/logrotate.d/. I have created a file in it with the config above.

Explanation of some parameters:
- weekly: weekly says that you want to Linux to rotate your log files weekly, you can also set daily, monthly, yearly.

- rotate 4: it says that how many rotated files should be kept, here I keep 4 rotated files (one month).

- compress: well you tell me what this parameter does.

- delaycompress: some programs do not close file handlers immediately, here we tell log rotate to delay the compression.

- missingok: don't return error if the log file is missing

OK, the list goes on. Take a look at the manual yourself and see its options.
