nginx如何设置IP直接访问自动跳转到域名

编辑 /etc/nginx/sites-available/default 文件

添加绿色部分代码

server {
listen 80 default_server;
listen [::]:80 default_server;
return 301 https://servername.com:443$request_uri;
}

server {
        listen 443 ssl default;
        server_name _;
        ssl_certificate /etc/letsencrypt/live/servername.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/servername.com/privkey.pem;
        return 301 https://servername.com:443$request_uri;
}

保存，然后重启nginx服务器

# systemctl nginx restart
