这里以https://i.hivps.cn直接访问Seafile为例

server {
    listen 80;
    server_name i.hivps.cn;
    rewrite ^ https://$http_host$request_uri? permanent;
  }
server {
    listen 443 ssl;
    ssl on;
    ssl_certificate fullchain.pem;
    ssl_certificate_key privkey.pem;
    server_name i.hivps.cn;
    proxy_set_header X-Forwarded-For $remote_addr;
    
    location / {
        fastcgi_pass    127.0.0.1:8000;
        fastcgi_param   SCRIPT_FILENAME     $document_root$fastcgi_script_name;
        fastcgi_param   PATH_INFO           $fastcgi_script_name;

        fastcgi_param    SERVER_PROTOCOL        $server_protocol;
        fastcgi_param   QUERY_STRING        $query_string;
        fastcgi_param   REQUEST_METHOD      $request_method;
        fastcgi_param   CONTENT_TYPE        $content_type;
        fastcgi_param   CONTENT_LENGTH      $content_length;
        fastcgi_param    SERVER_ADDR         $server_addr;
        fastcgi_param    SERVER_PORT         $server_port;
        fastcgi_param    SERVER_NAME         $server_name;
        fastcgi_param   REMOTE_ADDR         $remote_addr;

        access_log /www/server/nginx/logs/seahub.access.log;
        error_log /www/server/nginx/logs/seahub.error.log;
    }

    location /seafhttp {
        rewrite ^/seafhttp(.*)$ $1 break;
        proxy_pass http://127.0.0.1:8082;
        client_max_body_size 0;
        proxy_connect_timeout  36000s;
        proxy_read_timeout  36000s;
    }

    location /media {
        root /data/ifiles/seafile-server-latest/seahub;
    }
}

补充：配置文件中的

/data/ifiles/seafile-server-latest/seahub 请自行替换为你的seahub所在目录，不然会CSS丢失

location/media{ 

root/data/ifiles/seafile-server-latest/seahub;}

设置后，Seafile后台对应设置参考如下：
