Question

我最近发现我的Linux测试服务器/ var / log /已满，它已使用3.8g。但是当我列出其中的文件时，它只能显示大约800M。

df -hl

我也尝试过 du -h ，似乎也在800M左右

那是为什么？如何解决这个问题？

谢谢

坦率

你好

使用du -h /var/log或ls -hal -R /var/log显示全部。在Linux上，即Raspberry Pi，我使用了一个简单的软链接来接收不需要的垃圾邮件日志。目标是像黑洞一样，吃掉了一切……

ln -sf /dev/null /var/log/anaconda.log

当然，您必须以超级Q用户 root
的身份执行此操作

为什么/ var / log /文件夹已满
