大家好，又见面了，我是你们的朋友全栈君。
在另外一种环境中，让我们假定你已经在机器上安装了一个名为“foobar”的应用程序，它会在/var/log下生成foobar.log日志文件。现在，你想要将它的日志定向到rsyslog服务器，这可以通过像下面这样在rsyslog配置文
件中加载imfile模块来实现。
首先，加载imfile模块，这只需做一次。
module(load=”imfile” PollingInterval=”5″)
然后，指定日志文件的路径以便imfile模块可以检测到：
mysql rsyslog配置:
uat-db01:/data01/mysql# cat /etc/rsyslog.conf | grep -v “^#” | grep -v “^$”
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$ModLoad imklog # provides kernel logging support (previously done by rklogd)
module(load=”imfile” PollingInterval=”5″)
$ModLoad imtcp
$InputTCPServerRun 514

installed software in a non-standard prefix.
