logrotate 无法旋转日志

Question

logrotate 无法旋转我的日志。我检查了文件权限，它们很好。

我什至尝试将“su root root”放在配置文件中，但我仍然面临同样的问题。

请在下面找到相关详细信息：

logrotate.conf 文件：

/var/log/testlog {
    compress
    delaycompress
     maxage 180
    rotate 15
    size 1024M
    start 1
    rotate 15
    missingok
}

调试日志：[使用“-d]

ls /var/log/testlog* 的输出：

有人可以给我一些提示来解决这个问题吗？

谢谢

我在这里一瘸一拐地出去，但联机帮助页指出

-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. 

所以 logrotate 不做任何事情。它只是写出它会做什么。如果您想要详细的输出，请提供 -v 而不是 -d 作为选项。

编辑： logrotate 发出类似消息的事实

 log /var/log/testlog.16.gz doesn't exist -- won't try to dispose of it

没什么好担心的。事实上，这是预期的行为！详细的输出准确地显示了它在做什么。它试图增加与不存在的最古老的文件testlog.15.gz开头的版本号还没有。一旦执行了 15 次旋转，它将。这不是错误。一直持续到最后 testlog.1.gz确实存在并重命名为 testlog.2.gz

既然你指定

start 1 

testlog.0.gz 再次不在那里，但仍然：testlog 被移动到 testlog.1（没有压缩，因为延迟压缩）

最后它尝试处理第 16 个日志文件，因为

rotate 15

被给予。该文件不存在（再次：尚未），但这对您或程序都无关紧要。目录列表显示它完全按照我的要求执行。随着日志反复轮换，“丢失”的文件将出现，消息将消退。

毕竟你是在详细模式下运行程序，所以你应该期待这样的输出。
