CentOS 6.3：logrotate 和 btmp

Question

我必须在其他系统网络管理配置的服务器上配置 logrotate。首先，我检测到没有 crond，因此我必须安装sudo yum install vixie-cron。所有其他设置似乎都正常，/etc/cron.daily/logrotate文件存在。接下来我运行sudo logrotate -d -f logrotate.conf以检查它将如何工作。在执行结束时，我看到以下内容：

rotating pattern: /var/log/btmp  forced from command line (1 rotations)
empty log files are rotated, old logs are removed
considering log /var/log/btmp
  log needs rotating
rotating log /var/log/btmp, log->rotateCount is 1
dateext suffix '-20131004'
glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
glob finding old rotated logs failed
renaming /var/log/btmp to /var/log/btmp-20131004
creating new /var/log/btmp mode = 0600 uid = 0 gid = 22

但什么也没有发生，/var/log/btmp大小仍然相同，并且/var/log/btmp-20131004不存在。

Answer 1

你告诉它不要这么做。从manlogrotate 页面上可以看到：

   -d, --debug
          Turns on debug mode and implies -v.  In debug mode, no changes
          will be made to the logs or to the logrotate state file.

笔记 ” no changes will be made to the logs”。
