# Mac Mini 配置 SSH 免密登录到 NAS
|
||
|
||
## 概述
|
||
|
||
本文档记录 Mac Mini (192.168.3.189) 配置 SSH 免密登录到 NAS (192.168.3.17) 的详细步骤。
|
||
|
||
## 前提条件
|
||
|
||
- Mac Mini 已安装 SSH 客户端（内置）
|
||
- NAS 已开启 SSH 服务
|
||
- 拥有 NAS 用户名和密码
|
||
|
||
## SSH 密钥配置
|
||
|
||
### 1. 生成 SSH 密钥（如不存在）
|
||
|
||
```bash
|
||
ssh-keygen -t ed25519 -N "" -f ~/.ssh/id_ed25519
|
||
```
|
||
|
||
### 2. 传输公钥到 NAS
|
||
|
||
```bash
|
||
# 方法1：使用 sshpass（需要安装）
|
||
sshpass -p 'NAS密码' ssh -o StrictHostKeyChecking=no shenwei@192.168.3.17 'cat >> ~/.ssh/authorized_keys'
|
||
|
||
# 方法2：手动复制
|
||
# 1. 查看公钥
|
||
cat ~/.ssh/id_ed25519.pub
|
||
# 2. 登录 NAS
|
||
ssh shenwei@192.168.3.17
|
||
# 3. 追加公钥到 authorized_keys
|
||
echo '公钥内容' >> ~/.ssh/authorized_keys
|
||
```
|
||
|
||
## ~/.ssh/config 配置
|
||
|
||
### 完整配置示例
|
||
|
||
```bash
|
||
# NAS
|
||
Host nas
|
||
HostName 192.168.3.17
|
||
User shenwei
|
||
IdentityFile ~/.ssh/id_ed25519
|
||
ProxyCommand none
|
||
|
||
# Ubuntu1
|
||
Host ubuntu1
|
||
HostName 192.168.3.47
|
||
User shenwei
|
||
IdentityFile ~/.ssh/id_ed25519
|
||
ProxyCommand none
|
||
|
||
# Ubuntu2
|
||
Host ubuntu2
|
||
HostName 192.168.3.45
|
||
User shenwei
|
||
IdentityFile ~/.ssh/id_ed25519
|
||
ProxyCommand none
|
||
|
||
# Mac Mini (本地)
|
||
Host macmini
|
||
HostName 192.168.3.189
|
||
User weishen
|
||
IdentityFile ~/.ssh/id_ed25519
|
||
ProxyCommand none
|
||
|
||
# VPS1
|
||
Host vps1
|
||
HostName 192.227.222.142
|
||
User root
|
||
IdentityFile ~/.ssh/id_ed25519
|
||
ProxyCommand none
|
||
|
||
# VPS2
|
||
Host vps2
|
||
HostName 104.194.92.188
|
||
User root
|
||
IdentityFile ~/.ssh/id_ed25519
|
||
ProxyCommand none
|
||
```
|
||
|
||
## 测试免密登录
|
||
|
||
```bash
|
||
# 测试 NAS 连接
|
||
ssh nas "echo success"
|
||
|
||
# 测试所有服务器
|
||
for server in macmini ubuntu1 ubuntu2 nas; do
|
||
ssh $server "echo $server OK"
|
||
done
|
||
```
|
||
|
||
## 已配置的服务器
|
||
|
||
| 主机 | IP | 用户 | 状态 |
|
||
|------|-----|------|------|
|
||
| nas | 192.168.3.17 | shenwei | ✅ 已配置 |
|
||
| ubuntu1 | 192.168.3.47 | shenwei | ✅ 已配置 |
|
||
| ubuntu2 | 192.168.3.45 | shenwei | ✅ 已配置 |
|
||
| macmini | 192.168.3.189 | weishen | ✅ 已配置 |
|
||
| vps1 | 192.227.222.142 | root | ✅ 已配置 |
|
||
| vps2 | 104.194.92.188 | root | ✅ 已配置 |
|
||
|
||
## 故障排查
|
||
|
||
### 问题：Could not resolve hostname nas
|
||
|
||
**解决**：确保 ~/.ssh/config 中已添加 nas 别名配置
|
||
|
||
### 问题：Permission denied
|
||
|
||
**解决**：
|
||
1. 检查公钥是否已添加到目标服务器的 ~/.ssh/authorized_keys
|
||
2. 检查 ~/.ssh 目录权限应为 700
|
||
3. 检查 ~/.ssh/authorized_keys 权限应为 600
