即使有 rsyslog 配置，日志也不会进入日志文件

  • 772

我面临问题。我有两个不同的harpxoylinux 服务器（在不同的网络范围内）。在一台服务器上，我可以看到日志文件中生成了日志，但在另一台服务器上，日志文件中没有生成日志。

我已经比较了来自两台服务器的几乎所有可能的配置文件，它们看起来相同，但仍然找不到问题所在的线索。

Working服务器 -

配置中提到的两个端口haproxy都已启动。

这些文件在两台服务器上都是相同的

both are same
 
/usr/lib/systemd/system/rsyslog.service
 
/usr/lib/systemd/system/haproxy.service
 
/etc/sysconfig/haproxy
 
/etc/sysconfig/rsyslog
 
/etc/logrotate.d/haproxy

都有rsyslog-8.24.0-57.el7_9.1.x86_64和haproxy-1.5.18-9.el7_9.1.x86_64包。

两台服务器上的配置几乎相同，但在非工作服务器上，日志不会进入其自己的日志文件。

任何人都可以请帮忙。

谢谢，

    在前端部分下添加以下行后，日志现在正在日志文件中生成。
