Linux log日志清理

检查当前journal使用磁盘量

journalctl --disk-usage
journalctl --disk-usage

清理方法可以采用按照日期清理，或者按照允许保留的容量清理，只保存2天的日志，最大500M

journalctl --vacuum-time=2d
journalctl --vacuum-size=500M

如果要手工删除日志文件，则在删除前需要先轮转一次journal日志

systemctl kill --kill-who=main --signal=SIGUSR2 systemd-journald.service
systemctl kill --kill-who=main --signal=SIGUSR2 systemd-journald.service

统计文件夹中文件与目录大小（包含隐藏文件）

du -sh .[!.]*
