为什么我的configuration设置inheritance到子域服务器块？

我使用nginx和ssl通配符证书一样：

/etc/nginx/sites-enabled/example.com

server { listen 443 default_server ssl; server_name 192.168.0.1 example.com; include /etc/nginx/ssl.conf; error_log /var/log/nginx/example.com.error.ssl.log; access_log /var/log/nginx/example.com.access.ssl.log; root /var/www/example.com/; index index.html; location / { alias /var/www/example.com/example.com/; } } server { listen 80; server_name 192.168.0.1 example.com; return 301 https://$server_name$request_uri; } 

/etc/nginx/ssl.conf

包含的ssl.conf如下所示：

• 我们是否获得了一个access.log条目，用于cachingnginx中的内容
• nginx用php和两个node.js路由
• 来自代理caching的400个不良请求
• 增量子域名暴力强制？
• 将$ REMOTE_ADDR设置为真实的客户端IP

 ssl_certificate /etc/nginx/ssl/example.com/example.com.crt; ssl_certificate_key /etc/nginx/ssl/example.com/example.com.key; ssl_prefer_server_ciphers on; ssl_session_cache shared:SSL:10m; ssl_dhparam /etc/nginx/ssl/example.com/example.com_dhparam.pem; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers 'AES256+EECDH:AES256+EDH'; add_header Strict-Transport-Security "max-age=15768000; includeSubDomains"; add_header X-Frame-Options DENY; add_header X-Content-Type-Options nosniff; ssl_stapling on; ssl_stapling_verify on; resolver 8.8.4.4 8.8.8.8 valid=300s; resolver_timeout 10s; 

我的子域的服务器块如下所示：

/etc/nginx/sites-enabled/blog.example.com

 server { listen 443; server_name blog.example.com; error_log /var/log/nginx/blog.example.com.error.ssl.log; access_log /var/log/nginx/blog.example.com.access.ssl.log; root /var/www/blog.example.com/; index index.html; location / { proxy_pass http://localhost:2368/; proxy_set_header Host $host; proxy_buffering off; autoindex off; } } server { listen 80; server_name blog.example.com; return 301 https://$server_name$request_uri; } 

在子域上的https工作正常，但我想知道为什么它的工作，以及为什么blog.example.cominheritanceexample.com的设置，即使ssl.conf不包括在该服务器块。

在nginx文档中找不到有关从default_serverinheritance设置的任何内容。

这只是通配符证书的预期行为？

谢谢！
