HAProxy 1.7 统计设置

我尝试了多个有关启用 HAProxy 统计信息的网络教程（只需谷歌搜索 haproxy 统计信息并尝试前 10 个链接），但我相信这些适用于较旧的 HAProxy 版本。我在 Ubuntu 16.04 LTS 上运行 1.7。

这是我的 /etc/haproxy/haproxy.cfg 文件（其中包括 Datadog 提供的有关启用统计数据的说明）。

如果我删除 listen.... 块，它就可以正常启动。当它在那里时，我收到以下错误：

sudo service haproxy stop
sudo service haproxy start
Job for haproxy.service failed because the control process exited with error code. See "systemctl status haproxy.service" and "journalctl -xe" for details.

journalctl 和 systemctl 输出都显示“服务启动太快错误

有任何想法吗？

您对旧版本的看法是正确的。自从 HAProxy 1.5 中删除以来，绑定到代理（frontend或）声明开始的那一行上的端口就不再有效。listen

这是正确的形式：

listen stats
    bind :9000

请注意，您已经在frontend声明中这样做了。Alisten本质上是前端和后端的组合。
