前言

Web安掃提示Nginx使用了不安全的加密協議需要啟用TLSv1.2或者更高的協議，但是修改後還是一直掃出了TLSv1.0和TLSV1.1，總結下原因；

存在多個虛擬主機檔案

針對存在多個虛擬主機檔案的Nginx解析，每個虛擬主機檔案都需要修改；

Nginx的openssl套件不支援

配置符合PFS規範的加密套件

ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4:!DH:!DHE
 

開啟優先使用服務端加密套件

ssl_prefer_server_ciphers on;

配置示例

  listen 80;
  listen [::]:80;
  listen 443 ssl http2;
  listen [::]:443 ssl http2;
