如何让 rsyslog 将日志文件发送到 /var/log 之外的位置？

我有一个中央系统日志服务器（ubuntu 14.04 服务器），我将其设置为从许多服务器获取日志。

该服务器有一个非常大的存储硬盘，安装在/home/username/logs

我想将 rsyslog 日志发送到该位置，每个服务器都有不同的目录。

现在，我已经完成了所有工作，只是它只会将文件存储在 /var/log 目录中。

我的/etc/rsyslog.conf设置允许根据 IP 来存储来自不同服务器的日志文件

/etc/rsyslog.conf

#  /etc/rsyslog.conf    Configuration file for rsyslog.
#
#                       For more information see
#                       /usr/share/doc/rsyslog-doc/html/rsyslog_conf.html
#
#  Default logging rules can be found in /etc/rsyslog.d/50-default.conf

下面几行具体是我想要的

# This one is the template to generate the log filename dynamically, depending on the client's IP address.
$template FILENAME,"/var/log/%fromhost-ip%/syslog.log"

# Log all messages to the dynamically formed file. Now each clients log (192.168.1.2, 192.168.1.3,etc...), will be under a separate directory which is formed by the template FILENAME.
*.* ?FILENAME

但我不想有$template FILENAME,"var/log/...."，我希望它类似于$template FILENAME,"/home/username/logs/ "

是什么阻止我将目录更改为 /var/log 之外的目录，我该如何解决这个问题？

我知道我可能可以将该驱动器安装在 /var/log 下的某个地方，但我现在很好奇。

答案1

当我创建要存储 syslog 数据的目录时，我以 root 身份运行该命令。一旦我将所有者更改为 syslog，一切就都正常了。

呃，由于权限问题而创建 SE 问题很尴尬。
