如何在 nginx 上为子域名配置 SSL

目前，Nginx 配置为接受域名通配符 SSL 证书，例如：*.website.com。

我没有购买昂贵的通配符证书，而是为顶级域名 website.com 购买了单域 SSL 证书

现在，我发现该服务实际上使用了两个也需要使用 SSL 的子域。

例如：a.website.com 和 b.website.com

问题。

我如何更改 nginx 配置，以便当我为 a.website.com 购买单个子域 SSL 证书时，我可以指向 nginx 使用它。

Nginx 文件当前的样子如下：

server {
        listen 80;
        server_name website.io www.website.io;
        return 301 https://website.io$request_uri;
}

server {
        listen 443 ssl;
        ssl on;
        server_name website.io www.website.io;
    client_max_body_size 5m;
        add_header X-UA-Compatible    "IE=Edge,chrome=1";

    access_log /var/log/nginx/website.io_access.log;
    error_log /var/log/nginx/website.io_error.log;  

        ssl_certificate /srv/ssl/website.io/ssl.crt;
        ssl_certificate_key /srv/ssl/website.io/ssl.key;

        error_page 500 502 503 504 /500.html;
        location /500.html {
                root  /srv/static/website/maintenance;
        }

        location / {
        #auth_basic            "Restricted";
                #auth_basic_user_file  /etc/nginx/htpasswd.conf;

                include uwsgi_params;
        uwsgi_connect_timeout 30;
        uwsgi_read_timeout 30;
                uwsgi_pass 127.0.0.4:3031;
        }
}

您的配置将变成这样（为了清楚起见，我已将您示例中的域更改为域a.website.com并b.website.com按照您的问题正文进行更改）

server {
        listen 80;
        server_name a.website.com;
        return 301 https://a.website.com$request_uri;
        }   

server {
        listen 443 ssl;
        server_name a.website.com;
        client_max_body_size 5m;
        add_header X-UA-Compatible    "IE=Edge,chrome=1";

        access_log /var/log/nginx/a.website_access.log;
        error_log /var/log/nginx/a.website_error.log;  

        ssl_certificate /srv/ssl/a.website/ssl.crt;
        ssl_certificate_key /srv/ssl/a.website/ssl.key;

        error_page 500 502 503 504 /500.html;
        location /500.html {
                root  /srv/static/website/maintenance;
        }

        location / {
                #auth_basic            "Restricted";
                #auth_basic_user_file  /etc/nginx/htpasswd.conf;
                include uwsgi_params;
                uwsgi_connect_timeout 30;
                uwsgi_read_timeout 30;
                uwsgi_pass 127.0.0.4:3031;
        }
}

server {
        listen 80;
        server_name b.website.com;
        return 301 https://b.website.com$request_uri;
        }   

server {
        listen 443 ssl;
        server_name b.website.com;
        client_max_body_size 5m;
        add_header X-UA-Compatible    "IE=Edge,chrome=1";

        access_log /var/log/nginx/b.website.com_access.log;
        error_log /var/log/nginx/b.website.com_error.log;  

        ssl_certificate /srv/ssl/b.website.com/ssl.crt;
        ssl_certificate_key /srv/ssl/b.website.com/ssl.key;

        error_page 500 502 503 504 /500.html;
        location /500.html {
                root  /srv/static/website/maintenance;
        }

        location / {
                #auth_basic            "Restricted";
                #auth_basic_user_file  /etc/nginx/htpasswd.conf;
                include uwsgi_params;
                uwsgi_connect_timeout 30;
                uwsgi_read_timeout 30;
                uwsgi_pass 127.0.0.4:3031;
        }
}

您可以根据需要对任意数量的站点重复此操作，它只会为每个站点定义一个或多个额外的服务器块
