无法在 RHEL7 中向 localdomain 127.0.0.1:80 发布请求

Question

当我尝试向 127.0.0.1 发送请求时，它显示以下错误：

Post http://localhost/users: dial tcp 127.0.0.1:80: connect: connection refused

我已尝试以下操作：

Wget：

wget 127.0.0.1
--2020-04-02 09:52:01--  http://127.0.0.1/
Connecting to 127.0.0.1:80... failed: Connection refused.

跟踪路由：

traceroute 127.0.0.1
traceroute to 127.0.0.1 (127.0.0.1), 30 hops max, 60 byte packets
 1  localhost (127.0.0.1)  0.062 ms  0.029 ms  0.027 ms

平安：

ping 127.0.0.1
PING 127.0.0.1 (127.0.0.1) 56(84) bytes of data.
^C
--- 127.0.0.1 ping statistics ---
87 packets transmitted, 0 received, 100% packet loss, time 86006ms

有人可以帮忙配置这个吗？
