linux - logrotate 不压缩

Question

我们将 syslogd 设置为将来自几个不同服务器的所有日志发送到一个服务器中，全部发送到一个名为/var/log/centrallogs 的文件夹中。

我们为此目录使用以下日志轮换配置:

/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 似乎没有尝试进行任何旋转。

这是输出(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

我也尝试过使用 delaycompress，因为有些人已经成功了。

LR 可以很好地轮换日志，只是根本不对它们执行压缩。

查看该输出中唯一听起来有错误的部分:

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

我认为 LR 可能会被吓坏，因为它没有要删除的 .gz 文件，所以我创建了所需的日志文件的每个变体，它运行了一整夜，清除了 gz，旋转，但仍然没有压缩。

这让我有点生气，我们将不胜感激。

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。 “error: error [..]”消息可能不是来自 gzip，它倾向于在错误前加上“gzip: :”。

检查文件大小以查看它们是否很小(或者更具体地说，如果 gzip 认为压缩它们会使它们变大)。

notifempty 的类似评论。

delaycompress 只是意味着您可以拥有 .1 .2 .3 .4.gz .5.gz 等。 不是 compress 工作所必需的，并且实际上使它跳过压缩最近的几个文件。您可以同时使用两者，或者只使用压缩，而不是单独使用 delaycompress。

奇怪的是你没有频率/大小 { daily |每周 |大小 ___ } 在你的文件中。我从来没有尝试过在没有它们的情况下使用它们。
