VS Code Remote-SSH 1.91 配置：3步实现免密连接与离线安装 Server

VS Code Remote-SSH 1.91 深度配置指南免密连接与离线安装实战1. 环境准备与SSH密钥配置在开始配置VS Code Remote-SSH之前确保您已满足以下基础条件本地机器已安装VS Code 1.91或更高版本远程服务器运行Linux系统并开启SSH服务默认端口22本地与远程服务器之间网络可达直接连接或通过跳板机生成SSH密钥对本地操作ssh-keygen -t ed25519 -C vscode_remote -f ~/.ssh/vscode_rsa执行后会生成两个文件vscode_rsa私钥保留在本地vscode_rsa.pub公钥需上传到服务器服务器端密钥配置将公钥上传到服务器ssh-copy-id -i ~/.ssh/vscode_rsa.pub userremote_host验证免密登录ssh -i ~/.ssh/vscode_rsa userremote_host注意如果使用非默认密钥路径或端口需要在~/.ssh/config中添加配置Host my_remote HostName remote_host User user Port 22 IdentityFile ~/.ssh/vscode_rsa StrictHostKeyChecking no2.
