为什么Syslog没有将日志写入指定文件？

Question

我一直在尝试通过 Syslog 路由 Apache 的日志（由于某种原因，日志轮换已停止，使用 Syslog 和 logrotate 似乎是一个合理的解决方案）。

我已将 Apache 的错误日志发送到 local7，并通过记录器程序将访问日志通过管道传送到 local6。

我希望 Syslog分别将错误和访问日志写入/var/log/apache2/error.log和/var/log/apache2/access.log。

为此，我添加了以下内容/etc/syslog.conf：

# Logging for Apache using local7 facility for error messages
# and local6 for access log
# Added 20/06/2010 by Chris Bunney
local7.*                        /var/log/apache2/error.log
local6.*                        /var/log/apache2/access.log

我知道错误和访问日志被正确发送到 Syslog，因为它们显示在 中/var/log/syslog，但是它们没有被写入我想要的文件。

目标文件的原始文件权限：

-rw-r----- 1 root adm       0 2010-06-20 23:01 access.log

我一直在使用的目标文件的当前文件权限试图排除导致问题的此类事情：

-rw-rw-rw- 1 syslog adm       0 2010-06-20 23:01 access.log

对我来说一切都很好，那么为什么 Syslog 收到的消息没有写入我想要的文件？我错过了一些简单的东西吗？

Answer 1

您是否重新启动了 syslogd？您还可以使用lsof -f -p <pid-of-syslogd>查看它打开了哪些日志文件。syslog.conf 看起来不错，您可能想发布您的 apache 配置。

Answer 2

对于那些在从 Ubuntu LTS 12.04 更新到 14.04.1 后在谷歌搜索中迷失了类似症状的人：syslog 被 rsyslog 取代，由于某种原因，它没有被发行版升级安装。

解决方法是 apt-get install rsyslog
