同一服务器上同一后端的多个端口

同一服务器上同一后端的多个端口

我将 haproxy 与 ceph 集群结合使用，并在一台服务器上创建了多个具有不同端口的网关。我已将不同的端口号添加到后端配置，但似乎 haproxy 忽略了它。配置中缺少什么？

这是在网关运行的服务器上：

netstat -an|grep :808
tcp        0      0 10.118.199.1:8084       0.0.0.0:*               LISTEN
tcp        0      0 10.118.199.1:8080       0.0.0.0:*               LISTEN
tcp        0      0 10.118.199.1:8081       0.0.0.0:*               LISTEN
tcp        0      0 10.118.199.1:8082       0.0.0.0:*               LISTEN
tcp        0      0 10.118.199.1:8083       0.0.0.0:*               LISTEN
tcp        0      0 10.118.199.1:8080       10.100.112.111:56906    TIME_WAIT

这是我的 haproxy 配置：

我遗漏了什么或者误解了什么？

似乎多次查看 iptables -L 来判断操作系统防火墙是否正在运行还不够。即使它返回空表，服务是否正在运行，我都快疯了……
