什么是SSH？
SSH（Secure Shell）是一种安全的远程连接协议，允许你在不传输明文数据的情况下，安全地连接到远程服务器，它通过加密通信确保数据的安全性,防止未经授权的访问。
SSH远程连接VPS的步骤
配置SSH服务器
安装SSH
你必须在VPS上安装SSH服务，大多数VPS提供商都会提供这个服务,但有时可能需要手动安装。
sudo apt-get update sudo apt-get install -y ssh sudo systemctl enable ssh sudo systemctl start ssh
启用SSH配置文件
SSH默认配置通常存储在~/.ssh/config文件中，这个文件中包含了连接远程服务器的详细信息，包括公钥认证、端口映射等。
配置SSH客户端
添加远程服务器
在SSH客户端（比如终端）中,首先需要添加你要连接的远程服务器。
ssh -i ~/.ssh/config machine hosts
输入服务器的IP地址或域名，点击“Add Host”,填写服务器名称和端口。
设置公钥认证
SSH默认支持两种认证方式：公钥认证和密码认证，公钥认证更安全,建议使用公钥认证。
在~/.ssh/config文件中找到[Host]部分,添加公钥认证配置。
