1. 一些存放路径
   nginx: /etc/nginx
   静态html文件夹: /var/www/html/

2. xftp向ubuntu上传文件失败
   原因： 当前登录的账户不是root账户，所上传的文件夹权限不够
   解决办法：修改文件夹权限

chmod 777 文件夹名称

3. 我的nginx.conf配置

http {
		# https
        server {
        listen 443 ssl; 
        server_name carolin-violet.cloud; 

            # 上传文件大小的限制
		client_max_body_size 1024m;

        ssl_certificate /etc/ssl/carolin-violet.cloud_bundle.crt; 
        ssl_certificate_key /etc/ssl/carolin-violet.cloud.key; 

        ssl_session_timeout 5m;
        ssl_protocols TLSv1.2 TLSv1.3; 
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE; 
        ssl_prefer_server_ciphers on;

		location / {
	        proxy_set_header HOST $host;

	        proxy_set_header X-Forwarded-Proto $scheme;

	        proxy_set_header X-Real-IP $remote_addr;

	        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

	        proxy_pass http://127.0.0.1:8090/;

        }
      	location /violet-nav {
      		alias /var/www/html/nav;
      		index index.html;
        }

    }
