Question

如何将不同的应用/服务日志消息从一台服务器转发到中央rsyslog服务器？为了澄清： server1：swift（一体化）服务器2：rsyslog现在 swift日志位置：/ var / log / swift / all / log（server1） sshd日志位置：/ var / log / secure（server1）

我想将swift和sshd日志存储在server2的不同位置，问题是server2将日志记录在不同的位置，但这两个位置都存储来自all.log和安全的日志！我怎么过滤这个？

这是server1（swift）rsyslog.conf

Answer 1

当您通过imfile从文件中读取消息时，您可以分配标记（分别为swift-log和sshd）。您可以在接收服务器上使用这些标记进行过滤。类似的东西：

if $syslogtag == "sshd" then {
  action(type="omfile" file="/var/log/secure"
} else if $syslogtag == "swift-log" then {
  action(type="omfile" file="/var/log/swift
}

或者，您也可以更改imfile配置，以便为有尾文件（例如local6和local7）分配不同的工具。然后你可以使用BSD风格的配置进行过滤，如：

local6.* /var/log/secure # assuming local6 is assigned to sshd logs
local7.* /var/log/swift  # and local7 for swift logs

虽然对于某些事情你可能需要升级到最新版本的rsyslog（例如8.13是最新的，但许多发行版仍然带有5.x）。您可以在此处找到热门发行版的软件包：http://www.rsyslog.com/downloads/download-other/
