我有nginx conf如下：
server { listen 127.0.0.1:8080; server_name 127.0.0.1; client_max_body_size 20m; include /etc/nginx/conf.d/services/*.conf; # redirect server error pages to the static page /50x.html # error_page 500 /500.json; error_page 501 /501.json; error_page 502 /502.json; error_page 503 /503.json; error_page 504 /504.json; error_page 404 /404.json; location = /500.json { root /opt/lj/nginx; } location = /501.json { root /opt/lj/nginx; } location = /502.json { root /opt/lj/nginx; } location = /503.json { root /opt/lj/nginx; } location = /504.json { root /opt/lj/nginx; } location = /404.json { root /opt/lj/nginx; } } 在conf.d / services目录下，我有一个文件：
location /api/auth {proxy_pass http://127.0.0.1:8081;}
我有一个上游进程侦听8081的请求。 几乎准确2我们3次，请求得到适当的redirect，但每三次，我得到这个错误：
2014/10/09 03:03:52 [alert] 4572#0: *16 socket() failed (97: Address family not supported by protocol) while connecting to upstream, client: 127.0.0.1, server: 127.0.0.1, request: "GET /api/auth/1.0/companies/1/clients HTTP/1.1", upstream: "http://[::1]:8081/api/auth/1.0/companies/1/clients", host: "localhost:8080"
我不知道如何让nginx只转发上游能够理解的IPv4地址。
访问日志:(请注意，3次尝试中的1次会导致500次，其余次数会通过）

任何帮助将不胜感激！ 谢谢。
也许你的配置中有“localhost”而不是“127.0.0.1”。 你可以指定一个解析器，并设置ipv6关闭。
resolver 8.8.8.8 4.2.2.2 ipv6=off;
如果您的端口8081上的web服务也在nginx上，那么启用IPv6可以解决这个问题。
server { listen 8081; listen [::]:8081; .... }
