UseNginxToUpgradeHttps

Using the nginx reverse proxy, you can upgrade the HTTPS to the website non-intrusively: Modify the default file:

vim /etc/nginx/sites-available/default

server {
    # https使用443端口
    listen 443 ssl default_server;
    listen [::]:443 ssl default_server;
    # 配置HTTPS证书(这里是letsencrypt的示例)
    ssl_certificate /etc/letsencrypt/live/blog.saber2pr.top/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/blog.saber2pr.top/privkey.pem;
    ssl_session_timeout 5m;
    # 设置域名
    server_name blog.saber2pr.top;
}
