我们设置了syslogd，将来自几个不同服务器的所有日志发送到一个名为/var/log/centrallogs的文件夹中。
我们使用下面的日志循环配置这个目录：
/etc/logrotate.d/centrallogs：

/var/log/centrallogs/*log {
        rotate 5
        compress
        missingok
        notifempty
        sharedscripts
        postrotate
        /etc/init.d/httpd restart > /dev/null 2>/dev/null || true
        endscript
}

在测试中（使用logrotate -d centrallogs）LR似乎没有尝试做任何旋转。
下面是输出（注意，我已经重命名了站点，但这是我所做的唯一更改）：

compressing log with: /bin/gzip

error: error opening /var/log/centrallogs/site1_access.log.6.gz: No such file or directory

我也试过使用delaycompress，因为有些人已经成功了。
LR可以很好地旋转日志，只是根本不对它们执行压缩。
看看输出中唯一错误的部分：

error: error opening /var/log/centrallogs/site1_access.log.6.gz: No such file or directory

我想LR可能会崩溃，因为它没有一个.gz文件要删除，所以我创建了所需的日志文件的每一个变化，它运行了一夜，清除了gz的，旋转，但仍然没有压缩。
这让我有点抓狂，任何帮助都将受到感激。

根据日志，它看起来像是在运行/bin/gzip，通常gzip会压缩所有列出的文件--跳过任何丢失的文件--没有任何问题。请注意，如果结果较大，gzip不会强制压缩文件，这很容易发生在非常小的文件上。“错误：error [..]”消息可能不是来自gzip，它倾向于在错误前面加上“gzip：：“.
检查文件大小，看看它们是否很小（或者更具体地说，如果gzip认为压缩它们会使它们更大）。
类似的注解为notifempty。
delaycompress只是意味着你可以有.1.2.3.4.gz.5.gz等。这是 * 没有 * 必要使压缩工作，实际上使它跳过压缩最近的几个文件。您可以同时使用这两个函数，或者只使用compress函数，而不是delaycompress函数本身。
奇怪的是，你没有频率/大小{每天|周刊|size ___ }。我从来没有试过不戴眼镜就用。

针对您观察到的延迟压缩不起作用的问题，请注意，delaycompress功能仅在下一个循环周期中压缩前一个日志文件。如man logrotate中所述

delaycompress
      Postpone compression of the previous log file to the next rotation cycle.  
      This only has effect when used in combination with compress.

logrotate -fv /etc/logrotate.d/centrallogs

-f强制旋转，-d调试模式仅显示更多信息，-v详细模式

linux 对数旋转未压缩
