Question

我对HAProxy相当新，所以在这里寻找一个小方向。这里是问题的日志和配置。我试图强制使用特定的目标端口来使用特定的后端，但它无法正常工作。

Answer 1

修复是将mode tcp添加到后端部分，因此在这种情况下它默认为HTTP，显然SMTP并不知道如何与之交谈。无法相信我忘记了。

backend 890_imappop_25-smtp
    balance roundrobin
    mode tcp
    option redispatch
    stick-table type ip size 60k peers mypeers

    server filter1-mail 192.168.115.38:25 check
    server filter2-mail 192.168.115.39:25 check

根据端口重定向到后端
