Nginx排错：Nginx日志报错connect() failed (110: Connection timed out) while connecting to upstream

项目概述

网上商城项目，SpringCloud框架，Eureka端口10086，zuul端口10010，商品后端端口8001，前端端口9001

环境：

1、本地主机win10，ip:192.168.0.110，起后端和前端
2、虚拟机centos7,ip192.168.0.112，做反向代理服务器
3、修改本地主机host(C:\Windows\System32\drivers\etc\hosts)文件通过域名指向192.168.0.112

192.168.0.112   manage.leyou.com   // 前端
192.168.0.112   api.leyou.com      // zuul
192.168.0.112	www.leyou.com      // 商城

4、nginx.conf文件添加以下内容

server {
    listen       80;server_name  api.leyou.com;proxy_set_header X-Forwarded-Host $host;proxy_set_header X-Forwarded-Server $host;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;location / {
    proxy_pass http://192.168.0.110:10010;proxy_connect_timeout 6000;proxy_read_timeout 6000;}}server {
    listen       80;server_name  localhost;location / {
    root   html;index  index.html index.htm;}error_page   500 502 503 504  /50x.html;location = /50x.html {
    root   html;}}

问题描述

本机通过浏览器访问manage.leyou.com可以获得前端页面，当需要向后端发送请求获取数据时报错：

2020/04/29 17:48:11 [error] 22845#0: *118 connect() failed (110: Connection timed out) while connecting to upstream, client: 192.168.0.110, server: api.leyou.com, request: "GET /favicon.ico HTTP/1.1", upstream: "http://192.168.0.110:10010/favicon.ico", host: "api.leyou.com", referrer: "http://api.leyou.com/api/item/category/list?pid=0"

浏览器直接访问api.leyou.com出现nginx的502页面

问题解决

关闭虚拟机防火墙，关闭本机防火墙。
