我在同一个 Nginx 服务器上有 2 个站点。
我的第一个网站https://www.example.com以下所有地址均必须重定向到此域：
xx.xx.xx.xxx
我的第二个网站https://analytics.example.com以下地址必须重定向至该域：
如果我禁用第二个站点，第一个站点仍能正常工作。
当我使用 Nginx 激活多个站点时，会发生冲突。我该如何解决？
使用以下设置：
ubuntu@www-example-com ~ $ sudo nginx -t

对于这两个站点，我遇到了相同的错误：
答案1
ipv6only=on是多余的，因为这是默认设置。它不需要出现在listen配置中的任何指令中。
如果存在，它也只能对于任何给定的地址和端口对出现一次。
您应该将其从所有listen指令中删除。
答案2
错误消息nginx: [emerg] duplicate listen options for...意味着您对同一个端口多次应用了同一个参数。也就是说，ipv6only=on此处代码中的第二个参数：
示例.com：
listen [::]:80 ipv6only=on default_server;
analytics.example.com
listen [::]:80 ipv6only=on; # <- this is duplicate and raises the error
线索就隐藏在nginx 文档：
listen 指令可以包含多个特定于套接字相关系统调用的附加参数。这些参数可以在任何 listen 指令中指定，但对于给定的地址：端口对只能指定一次。
这适用于任何“附加”参数（例如，，，deferred等）。当然，正如前面提到的，您不再需要指定任何内容。reuseportso_keepaliveipv6only=on
那么最好的做法是仅在第一个或 default_server 声明中指定任何参数。可以假设后续listen指令将继承这些。
