# Docker安装nginx 启动后报错 #

这是nginx error.log原话

#### \[error\] 5\#5: \*1 connect() failed (111: Connection refused) while connecting to upstream, client: xxx.xxx.xxx.xxx, server: xxx.xxx.com, request: “GET /v1/api/xxxx HTTP/1.1”, upstream: “http://127.0.0.1:8091/v1/xxx”, host: “xxx.xxx.com” ####

我这个服务相对简单 Docker容器 spring cloud服务分别是：service服务提供、网关api、运营api、 端口分别是8090服务、8091网关api、8092运营 api  
效果如下：

这没什么好说的  
然后开始搭建nginx

docker run --name nginx -d -p 80:80 -p 443:443 -v /docker/nginx/logs:/var/log/nginx -v /docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /docker/nginx/www:/usr/share/nginx/html nginx

> 开启ssl  
> 最后把安全证书 cp到容器 ：docker cp /root/cert/ 0f186a79f090:/root/  
> 最后启动访问：docker start 0f186a79f090  
> 访问后：

## Nginx Error: ##

2020/03/18 04:45:15 [error] 5#5: *1 connect() failed (111: Connection refused) while connecting to upstream, client: xxx.xxx.xxx.xxx, server: xxx.xxx.xxx.xxx, request: "GET /v1/api/xxx HTTP/1.1", upstream: "http://127.0.0.1:8091/v1/api/xxx", host: "xxx.xxx.xxx.xxx"
    2020/03/18 04:45:15 [error] 5#5: *1 connect() failed (111: Connection refused) while connecting to upstream, client: xxx.xxx.xxx.xxx, server: xxx.xxx.xxx.xxx, request: "GET /favicon.ico HTTP/1.1", upstream: "http://127.0.0.1:8091/xxx", host: "xxx.xxx.xxx.xxx", referrer: "https://xxx.xxx.xxx.xxx/v1/api/xxxx"

解决方案：  
我的conf server是这样配置的

server { 
        # IPv4
        listen  80;
        listen  443 ssl;
        # IPv6
        listen  [::]:80;
        listen  [::]:443 ssl;
    
        server_name xxx.xxx.xxx.xxx;
    
        # certs sent to the client in SERVER HELLO are concatenated in ssl_certificate
        ssl_certificate     /root/cert/xxx.xxx.xxx.xxx.pem;
        ssl_certificate_key /root/cert/xxx.xxx.xxx.xxx.key;
    
        # curl https://ssl-config.mozilla.org/ffdhe2048.txt > /etc/nginx/ssl/dhparam.pem
        # ssl_dhparam ssl/dhparam.pem;
        location / { 
    	client_max_body_size 20M;
    	proxy_pass  http://xxx.xxx.xxx.xxx:8091;
    	proxy_set_header Host       $host;
        proxy_set_header X-Real-IP  $remote_addr;
        }
    
        access_log  /var/log/nginx/xxx.xxx.xxx.xxx.log main;
        error_log   /var/log/nginx/xxx.xxx.xxx.xxx.log;
    }

## **注意这里：** ##

location / { 
    	client_max_body_size 20M;
    	# 我的问题就是这里 原来是：proxy_pass http://localhost:8091;
    	# 后来改成：proxy_pass http://127.0.0.1:8091; 也不行！
    	# 改成解决：proxy_pass http://xxx.xxx.xxx:8091; ok了！（xxx.xxx.xxx是你服务器公网IP 如：139.172.99.21:8091）
    	proxy_pass  http://xxx.xxx.xxx.xxx:8091;
    	proxy_set_header Host       $host;
        proxy_set_header X-Real-IP  $remote_addr;
        }

## 效果 ##
