在nginx proxy_pass中禁用IPv6

我的服务器没有IPv6地址。

但是,当我使用Nginx的proxy_pass与IPv4和IPv6上游,有时它会尝试使用IPv6发送传出请求:

2013/07/30 00:25:06 [error] 1930#0: *1482670 connect() to [AAAA:BBBB:C:DDD:E:F:GGG:HHH]:443 failed (101: Network is unreachable) while connecting to upstream, client: AA.BB.CC.DD, server: example.com, request: "GET /download/file HTTP/1.0", upstream: "https://[AAAA:BBBB:C:DDD:E:F:GGG:HHH]:443/download/file", host: "example.com" 

如何在proxy_pass中为传出请求禁用IPv6?

nginx.conf:

 upstream download { server download.example.com:443; keepalive 8; } location /download { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Connection ""; proxy_ignore_headers X-Accel-Redirect; proxy_http_version 1.1; resolver 8.8.8.8; resolver_timeout 5s; proxy_pass https://download; } 

nginx -V:

ip a

看起来有一个解决scheme,因为nginx> = 1.5.8:

  resolver 8.8.8.8 ipv6=off;
