尽管已从配置中删除，但 nginx 仍继续使用“默认 nginx 站点”进行应答

我希望有人能帮我解决这个奇怪的问题。在“干净”的服务器安装中，我有以下“website.com”和 nginx 配置，但如果您尝试转到 版本http，www.website.com它会呈现默认nginx 页面，而不是像配置的那样转发到https版本。该站点使用 AWS Linux ami，并且位于 elb 后面（因此有 elb-check 指令）。

在我的/sites-available（并且ln -s已经/sites-enabled）中，我所拥有的（即使在执行时# ls -lah）是： default_server website.com elb-check

配置（以及nginx.conf下面的）。

提前谢谢您！如果您需要其他信息/配置，请告诉我。

website.com：

    server {
    listen 80;
    server_name www.website.com;
    return 301 $scheme://www.website.com$request_uri;

nginx.conf：

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;


    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

    # Load Virtual Sites
    include /etc/nginx/sites-enabled/*;
    include /etc/nginx/sites-available/*;

    index   index.php index.html index.htm;
    server_tokens off;
}

默认服务器：

# To black-hole all other subdomain requests
server {
    listen 80;
    server_name _;
    return 444;
}

elb 检查：

# So the ELB sees the instance as still being alive
server {
    location /home/elb-check { 
    access_log off;
    return 200;
    add_header Content-Type text/plain;
    }
}

答案1

如果没有明确定义默认服务器，Nginx 将选择配置中的第一个服务器。安装一个虚拟默认服务器。

# This just prevents Nginx picking a random default server if it doesn't know which
# server block to send a request to
server {
  listen      80 default_server;
  server_name _;
  return 444;
  access_log off; log_not_found off;
}

您可能还想定义一个默认的 https 服务器，尽管如果它不在特定域上，它可能会生成证书警告。我不介意。

我认为另一个问题与 nginx.conf 有关，在底部您包含了 sites-enabled/*。您同时包含了可用配置和已启用配置。您加载了两次配置，因此 nginx 在找不到有效配置时将始终默认使用基本配置。

# Load Virtual Sites
    include /etc/nginx/sites-enabled/*;
    include /etc/nginx/sites-available/*; <-- do not need this too.
