journalctl 로그 용량/보존 기한 설정하기

var/log 에 용량이 많아 확인해보니 journal log 가 4G 넘게 쌓여있는걸 보고, 

stackoverflow 를 참고해 해결했다.

 

 

The self maintenance method is to vacuum the logs by size or time.

Retain only the past two days:

journalctl --vacuum-time=2d

Retain only the past 500 MB:

journalctl --vacuum-size=500M

man journalctl for more information.
