# ⚠️ 安装问题解决方案
|
||
|
||
## 你遇到的错误
|
||
|
||
```
|
||
go: github.com/google/gopacket@v1.2.3: reading github.com/google/gopacket/go.mod at revision v1.2.3: unknown revision v1.2.3
|
||
```
|
||
|
||
## ✅ 已修复
|
||
|
||
这个问题已经解决！原因是 `go.mod` 文件中包含了一个不存在的依赖版本。
|
||
|
||
### 修复内容
|
||
|
||
1. **删除了无效依赖** - `github.com/google/gopacket`（实际未使用）
|
||
2. **添加了正确的 SQLite 驱动** - `github.com/mattn/go-sqlite3`
|
||
3. **更新了 `go.mod`** - 使用稳定版本

## 📋 完整安装步骤（从零开始）
|
||
|
||
### 1. 安装系统依赖
|
||
|
||
```bash
|
||
# Debian/Ubuntu
|
||
sudo apt update
|
||
sudo apt install -y git build-essential libsqlite3-dev
|
||
|
||
# RHEL/CentOS
|
||
sudo yum install -y git gcc make sqlite-devel
|
||
```
|
||
|
||
### 2. 安装 Go（如果未安装）
|
||
|
||
```bash
|
||
# 下载 Go 1.21
|
||
wget https://go.dev/dl/go1.21.0.linux-amd64.tar.gz
|
||
|
||
# 解压
|
||
sudo tar -C /usr/local -xzf go1.21.0.linux-amd64.tar.gz
|
||
|
||
# 添加到 PATH
|
||
echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.bashrc
|
||
source ~/.bashrc
|
||
|
||
# 验证
|
||
go version
|
||
```
|
||
|
||
### 3. 安装项目
|
||
|
||
```bash
|
||
# 进入项目目录
|
||
cd /path/to/dhcp-dns-manager
|
||
|
||
# 运行修复脚本（如果有依赖问题）
|
||
./fix-deps.sh
|
||
|
||
# 运行安装脚本
|
||
sudo ./install.sh
|
||
```

## 🔍 验证安装
|
||
|
||
### 检查服务状态
|
||
```bash
|
||
systemctl status dhcp-dns-manager
|
||
```
|
||
|
||
应该显示：
|
||
```
|
||
● dhcp-dns-manager.service - DHCP & DNS Manager Service
|
||
Active: active (running)
|
||
```
|
||
|
||
### 检查端口
|
||
```bash
|
||
sudo netstat -ulpn | grep -E ':(53|67|8080)'
|
||
```
|
||
|
||
应该看到：
|
||
- UDP 53 - DNS
|
||
- UDP 67 - DHCP
|
||
- TCP 8080 - Web UI
|
||
|
||
### 访问 Web 界面
|
||
|
||
浏览器打开：`http://your-server-ip:8080`
|
||
|
||
默认账号：`admin` / `admin`
|

## ❓ 其他常见问题
|
||
|
||
### 问题：`gcc: command not found`
|
||
|
||
**解决：**
|
||
```bash
|
||
sudo apt install build-essential
|
||
```
|
||
|
||
### 问题：`sqlite3.h: No such file or directory`
|
||
|
||
**解决：**
|
||
```bash
|
||
sudo apt install libsqlite3-dev
|
||
```
|
||
|
||
### 问题：`port 8080 already in use`
|
||
|
||
**解决：**
|
||
1. 查找占用进程：
|
||
```bash
|
||
sudo lsof -i :8080
|
||
```
|
||
2. 停止占用进程或修改 `configs/config.json` 中的端口
|
||
|
||
### 问题：`permission denied` 绑定端口
|
||
|
||
**解决：**
|
||
DHCP (67) 和 DNS (53) 需要 root 权限：
|
||
```bash
|
||
sudo systemctl restart dhcp-dns-manager
|
||
```
|
||
|
||
或使用 Docker 部署（自动处理权限）。
