Nginx 代理通行证 - 禁用 ipv6

Question

我有如下的nginx conf:

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 目录中，我有一个文件:

location /api/auth {proxy_pass     http://127.0.0.1:8081;}

我有一个上游进程在 8081 上监听请求。几乎准确地 2 我们的 3 次，请求被适本地重定向，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 只转发到上游理解的 IPv4 地址。

访问日志:(请注意 3 次尝试中的 1 次结果为 500，其余通过)

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”。您可以指定解析器并将 ipv6 设置为关闭。

resolver 8.8.8.8 4.2.2.2 ipv6=off;

如果您在 8081 端口上的 Web 服务也在 nginx 上，那么为此启用 IPv6 可以解决问题。

server {
    listen 8081;
    listen [::]:8081;
    ....
}
