Ubuntu 12.04 中的 Squid3 logrotate 错误

在 Ubuntu 12.04 服务器中，Squid3 的 logrotate 不起作用。我发现这个问题时，注意到分区因 squid3 日志而变满。强制 logrotate 会产生以下错误：

~# logrotate -f /etc/logrotate.d/squid3
error: error running shared prerotate script for '/var/log/squid3/*.log

以下是完整的调试输出：

~# logrotate -f /etc/logrotate.d/squid3 -d
reading config file /etc/logrotate.d/squid3
reading config info for /var/log/squid3/*.log

知道这里可以检查什么吗？谢谢。

正如日志条目所示，脚本存在错误prerotate。

为了调试这个问题，可以从配置中删除脚本，然后逐个添加回来，直到找到有问题的脚本。

也可以手动执行它们以查看哪一个失败，但在这种情况下，OP 说它们默默失败了。

使用logrotate -vf /etc/logrotate.d/squid3（-v 表示 vervose，-f 表示 force）是另一种选择，在这种情况下有助于获取有关问题的数据。
