洛格旋转说它会旋转，但不会。

Question

我在Raspbian 9系统上有一个奇怪的问题。

Log转速似乎被配置为每七天旋转一次/var/log/syslog。当我运行logrotate -f -d /etc/logrotate.conf时，输出告诉我：

rotating pattern: /var/log/syslog
 forced from command line (7 rotations)
empty log files are not rotated, old logs are removed
considering log /var/log/syslog
  Now: 2021-03-16 09:56
  Last rotated at 2020-11-02 12:26
  log needs rotating
rotating log /var/log/syslog, log->rotateCount is 7
dateext suffix '-20210316'
glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
compressing log with: /bin/gzip
renaming /var/log/syslog.7.gz to /var/log/syslog.8.gz (rotatecount 7, logstart 1, i 7),
renaming /var/log/syslog.6.gz to /var/log/syslog.7.gz (rotatecount 7, logstart 1, i 6),
renaming /var/log/syslog.5.gz to /var/log/syslog.6.gz (rotatecount 7, logstart 1, i 5),
renaming /var/log/syslog.4.gz to /var/log/syslog.5.gz (rotatecount 7, logstart 1, i 4),
renaming /var/log/syslog.3.gz to /var/log/syslog.4.gz (rotatecount 7, logstart 1, i 3),
renaming /var/log/syslog.2.gz to /var/log/syslog.3.gz (rotatecount 7, logstart 1, i 2),
renaming /var/log/syslog.1.gz to /var/log/syslog.2.gz (rotatecount 7, logstart 1, i 1),
renaming /var/log/syslog.0.gz to /var/log/syslog.1.gz (rotatecount 7, logstart 1, i 0),
log /var/log/syslog.8.gz doesn't exist -- won't try to dispose of it
renaming /var/log/syslog to /var/log/syslog.1
creating new /var/log/syslog mode = 0640 uid = 0 gid = 4
running postrotate script
running script with arg /var/log/syslog: "
                invoke-rc.d rsyslog rotate > /dev/null
"

因此，它表示将/var/log/syslog重命名为/var/log/syslog.1，并创建一个新的syslog。所以到目前为止一切都还好。

只是它确实注意到了。之后不存在syAdd.1-.1，syslog文件与以前相同。什么都没发生。

值得一提的是: /var/log是tmpfs-这是否相关？挂载as：tmpfs on /var/log type tmpfs (rw,nosuid,nodev,relatime)

谢谢你的想法！

你说你在运行logrotate -f -d /etc/logrotate.conf。

选项-d (重点雷)的描述：

-d，--调试打开调试模式，这意味着不对日志进行任何更改，日志旋转状态文件也不会被更新。只打印调试消息。

不使用-d选项，再试一次。
