Question

在haproxy 1.5中检查健康状况时出现问题。在sample-backend或sample-backend2中，haproxy不会在tcp模式下检查状态，即使我指定tcp模式，它也始终检查L7模式。它总是UP。

这是我的配置：

global
log         127.0.0.1 local2
chroot      /var/lib/haproxy
pidfile     /var/run/haproxy.pid
maxconn     4000
user        haproxy
group       haproxy
daemon
defaults

option http-server-close
option forwardfor       except 127.0.0.0/8
option                  redispatch

timeout check           10s
maxconn                 3000

我的错误在哪里？谢谢！

Answer 1

我的版本是1.5.4，所以它在tcpcheck中有错误。更新到最新版本，它可以工作。

Haproxy不会在tcp模式下检查后端
