没有定义解析s3-eu-west-1.amazonaws.com的解析器

Question

我的所有xml文件都存储在AWS S3中，我想通过我的网站显示它们：

Nginx conf：

location ~ \.xml$ {

    proxy_pass https://s3-eu-west-1.amazonaws.com/bucket-name/sitemap$request_uri;

}

但我得到了502并且日志说

[error] 13295#13295: *26 no resolver defined to resolve s3-eu-west-1.amazonaws.com

如果我定义一个像

这样的解析器

resolver s3-eu-west-1.amazonaws.com;

我得到了

[error] 14430#14430: *7 s3-eu-west-1.amazonaws.com could not be resolved (110: Operation timed out),

感谢您的帮助

Answer 1

我找到了解决方案：

location ~ \.xml$ {

    rewrite ^ /<bucket>/sitemap$request_uri break;
    proxy_pass https://s3-eu-west-1.amazonaws.com;
}

Answer 2

您的VPC中的AWS DNS为likely at 10.0.0.2（它是基本CIDR加2）。

添加resolver和resolver_timeout：

location ~ \.xml$ {
    resolver         10.0.0.2 valid=300s;
    resolver_timeout 10s;

    proxy_pass https://s3-eu-west-1.amazonaws.com/bucketname/sitemap$request_uri;
}

注意：在EC2 Classic中AWS DNS server is located at 172.16.0.23。

Answer 3

此实例中的解析程序将是您用于解析DNS名称的本地或外部DNS服务器，而不是s3网址。
