在 **CentOS** 服务器上开启并配置 **SFTP Server**，可以按照以下步骤进行： --- ## ✅ **步骤 1：安装 OpenSSH** ```bash # 更新系统并安装 OpenSSH sudo yum update -y sudo yum install -y openssh-server ``` --- ## ✅ **步骤 2：启动并启用 SSH 服务** ```bash # 启动 SSH 服务 sudo systemctl start sshd # 设置开机自启动 sudo systemctl enable sshd ``` --- ## ✅ **步骤 3：创建 SFTP 用户** ```bash # 创建 SFTP 用户 sudo useradd -m sftpuser # 设置 SFTP 用户密码 sudo passwd sftpuser ``` --- ## ✅ **步骤 4：创建 SFTP 专用目录** ```bash # 创建上传目录 sudo mkdir -p /home/sftpuser/upload # 设置目录权限 sudo chown root:root /home/sftpuser sudo chmod 755 /home/sftpuser # 允许 sftpuser 访问 upload 目录 sudo chown sftpuser:sftpuser /home/sftpuser/upload ``` --- ## ✅ **步骤 5：修改 SSH 配置** 编辑 `sshd_config` 文件： ```bash sudo vim /etc/ssh/sshd_config ``` ### 添加或修改以下配置： ```bash # 禁止 SFTP 用户使用 shell Match User sftpuser ChrootDirectory /home/sftpuser ForceCommand internal-sftp AllowTcpForwarding no X11Forwarding no ``` > ⚠️ **注意：** - `Match User`：指定仅对 `sftpuser` 生效的规则。 - `ChrootDirectory`：将 SFTP 用户限制在 `/home/sftpuser` 目录中。 --- ## ✅ **步骤 6：重启 SSH 服务** ```bash sudo systemctl restart sshd ``` --- ## ✅ **步骤 7：验证 SFTP 连接** ### 测试使用 SFTP 连接 ```bash sftp sftpuser@<your-server-ip> ``` ### 常用 SFTP 命令： - `put <localfile>`：上传文件 - `get <remotefile>`：下载文件 - `ls`：列出远程目录 - `exit`：退出 --- ## ✅ **可选：开启防火墙 SFTP 端口（默认 22）** ```bash # 开启 SSH 端口 sudo firewall-cmd --permanent --zone=public --add-port=22/tcp # 重新加载防火墙 sudo firewall-cmd --reload ``` --- ## 🎉 **完成！** 现在 `sftpuser` 可以通过 SFTP 连接到服务器，并且只能访问 `/home/sftpuser/upload` 目录。

style="font-weight: bold;"><span leaf=""><span textstyle="" style="font-size: 20px;">一、为什么表格数据是大模型的“拦路虎”？</span></span></span></h3> <p style="text-indent: 2em;"><span style="white-space: pre-wrap;-en-paragraph:true;"><span leaf=""><span textstyle="" style="font-size: 17px;">先说说痛点。大模型天生擅长处理非结构化数据，比如一篇散文、一段聊天记录，它能迅速抓住重点。可表格不一样，表格是结构化的，字段清晰、数据规整，直接丢给模型，它可能会一脸茫然，完全不知道从哪儿下手。</span></span></span></p> <p style="text-indent: 2em;"><span style="white-space: pre-wrap;-en-paragraph:true;"><span leaf=""><span textstyle="" style="font-size: 17px;">那怎么办呢？其实很简单，核心思路就是把表格“翻译”成大模型能懂的语言，再搭配一个好用的存储和检索方案。听起来有点玄乎？别慌，接下来我会一步步拆解，带你把这事儿弄明白。</span></span></span></p> <p

style="font-size: 17px;">经过一番研究，我总结了大模型处理表格的四大核心步骤：向量化、存储、索引、检索。每一步都有多种方法可选，我不仅会讲清楚原理，还会直接上代码，方便你动手实践！</span></span></span></p> <h4><span leaf=""><span textstyle="" style="font-size: 17px;font-weight:

17px;">表格不像文本，不能直接喂给模型，得先把它转成向量。这里有三种主流方法，针对不同场景各有妙用：</span></span></span></p> <h5><span leaf=""><span textstyle="" style="font-size: 17px;font-weight: bold;">方法1：逐行向量化——每行变“文章”</span></span></h5> <p><span style="font-weight: bold;"><span leaf=""><span textstyle="" style="font-size: 17px;">思路</span></span></span><span leaf=""><span textstyle="" style="font-size: 17px;">：把表格的每一行拼接成一句话，用嵌入模型生成向量，再存进向量数据库。</span></span></p> <p><span style="font-weight: bold;"><span leaf=""><span textstyle="" style="font-size: 17px;">适用场景</span></span></span><span leaf=""><span textstyle="" style="font-size: 17px;">：想查单行数据，比如“收入最高的科技公司”。</span></span></p> <p><span style="font-weight: bold;-en-paragraph:true;"><span leaf=""><span textstyle="" style="font-size:
