# mc-gateway
|
||
|
||
一个简易的 Minecraft 网关,通过客户端握手里的 host 将流量转发到对应的后端 Minecraft 服务器。
|
||
|
||
## 启动
|
||
|
||
mc-gateway 默认不依赖配置文件。直接启动后会在 `25565` 端口同时提供 Minecraft TCP 转发入口和后台管理入口:
|
||
|
||
- Admin 页面:`/admin/`
|
||
- Admin API:`/admin/api`
|
||
- SQLite 数据库:`mc-gateway.sqlite3`
|
||
|
||
首次启动时,如果用户表为空,可以通过 Admin 页面初始化管理员账号。也可以用 `MC_GATEWAY_ADMIN_PASSWORD` 在启动时创建默认管理员用户 `admin`。
|
||
|
||
### 启动期环境变量
|
||
|
||
| 环境变量 | 默认值 | 说明 |
|
||
| --- | --- | --- |
|
||
| `MC_GATEWAY_TCP_ADMIN_PORT` | `25565` | TCP/Admin 共享监听端口 |
|
||
| `MC_GATEWAY_ADMIN_PATH` | `/admin/` | Admin 页面路径 |
|
||
| `MC_GATEWAY_ADMIN_API_PREFIX` | `/admin/api` | Admin API 前缀 |
|
||
| `MC_GATEWAY_DB` | `mc-gateway.sqlite3` | SQLite 数据库路径 |
|
||
| `MC_GATEWAY_ADMIN_PASSWORD` | 空 | 首次启动时创建默认管理员密码 |
|
||
|
||
服务启停、KCP/QUIC/WebSocket 参数、用户、权限和路由都通过后台管理写入 SQLite,不再使用 `config.toml` 作为启动配置或路由来源。
|
||
|
||
## 权限
|
||
|
||
后台管理内置三类角色:
|
||
|
||
| 角色 | 能力 |
|
||
| --- | --- |
|
||
| 管理员 | 管理用户、服务、路由和审计日志 |
|
||
| 成员 | 查看状态,管理路由 |
|
||
| 游客 | 查看当前路由 |
|
||
|
||
## 路由
|
||
|
||
路由记录存储在 SQLite 中,后台修改后会刷新内存快照。默认 fallback 路由的 host 为 `default`。
|
||
|
||
### upstream
|
||
|
||
路由上游支持多种协议。TCP 上游直接填写地址,其他协议在地址前加协议前缀:
|
||
|
||
| 协议 | 前缀 | 说明 |
|
||
| --- | --- | --- |
|
||
| tcp | 无 | 原始 TCP 连接 |
|
||
| kcp | `kcp://` | 使用 KCP 协议连接到服务器 |
|
||
| quic | `quic://` | 使用 QUIC 协议连接到服务器 |
|
||
| haproxy | `haproxy://` | 使用 HAProxy 协议连接到服务器 |
|
||
|
||
HAProxy 协议头会保存客户端真实 IP,适合需要在后端服务端获取真实客户端 IP 的场景。
|
||
|
||
## 可选服务
|
||
|
||
TCP/Admin listener 是基础入口,默认启用。KCP、QUIC、WebSocket 默认禁用,可以在后台管理中启用并配置端口和参数;配置修改后第一版按重启后生效处理。
|
||
|
||
| 服务 | 默认端口 | 说明 |
|
||
| --- | --- | --- |
|
||
| TCP/Admin | `25565` | Minecraft TCP 转发和后台管理共享入口 |
|
||
| KCP | `25565` | 可选 KCP 入口 |
|
||
| QUIC | `25565` | 可选 QUIC 入口 |
|
||
| WebSocket | `25566` | 可选 WebSocket 入口 |
|
||
|
||
## 日志
|
||
|
||
默认日志级别为 `info`,输出到标准输出。日志文件重开逻辑支持 logrotate 场景:
|
||
|
||
```logrotate
|
||
/var/log/mc-gateway.log {
|
||
copytruncate
|
||
daily
|
||
missingok
|
||
rotate 14
|
||
compress
|
||
compresscmd /usr/bin/zstd
|
||
compressext .zst
|
||
compressoptions -T0 --long
|
||
uncompresscmd /usr/bin/unzstd
|
||
notifempty
|
||
delaycompress
|
||
dateext
|
||
postrotate
|
||
if [ -f /dev/shm/mc-gateway.pid ]; then
|
||
kill -SIGHUP $(cat /dev/shm/mc-gateway.pid)
|
||
fi
|
||
endscript
|
||
}
|
||
```
