查看“Rsyslog Journal日志 syslog清理”的源代码


=var/log/日志文件太大，清理journal=
<pre>
# journalctl --disk-usage
Archived and active journals take up 4G on disk.

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1天的日志，最大500M

#执行这个就行了
journalctl --vacuum-time=1d

journalctl --vacuum-size=500M


# journalctl --disk-usage
Archived and active journals take up 96.1M on disk.

</pre>
