|
||
|
||
## 新旧对比
|
||
|
||
| 项目 | 旧服务器 (1panel-server) | 新服务器 (47.109.203.92) |
|
||
|------|------------------------|-------------------------|
|
||
| 系统 | - | Debian 13.5 |
|
||
| CPU | - | 2 核 |
|
||
| 内存 | - | 1.6 GiB |
|
||
| 磁盘 | - | 40G (可用 36G) |
|
||
| 区域 | - | 成都 |
|
||
| 角色 | 当前生产+开发 | 目标生产+开发 |
|
||
|
||
## 阶段 1 — 基础设施安装
|
||
|
||
### 1.1 安装 Docker
|
||
```bash
|
||
apt update && apt install -y docker.io docker-compose-v2
|
||
```
|
||
|
||
### 1.2 启动 PostgreSQL
|
||
```bash
|
||
docker run -d --name postgres \
|
||
--network host \
|
||
-e POSTGRES_PASSWORD=password \
|
||
-v /var/lib/postgresql/data:/var/lib/postgresql/data \
|
||
postgres:17.6-alpine
|
||
```
|
||
创建数据库：milkydata、milkydata_dev
|
||
|
||
### 1.3 从旧服务器迁移数据库
|
||
```bash
|
||
# 旧服务器导出
|
||
pg_dump -Fc milkydata > /tmp/milkydata.dump
|
||
# 新服务器导入
|
||
pg_restore -d milkydata /tmp/milkydata.dump
|
||
```
|
||
|
||
### 1.4 启动 OpenResty
|
||
```bash
|
||
docker run -d --name openresty \
|
||
--network host \
|
||
-v /www/sites:/www/sites \
|
||
1panel/openresty:1.21.4.3-3-3-focal
|
||
```
|
||
|
||
### 1.5 复制 SSL 证书 + nginx 配置
|
||
```bash
|
||
rsync -av root@1panel-server:/www/sites/ /www/sites/
|
||
```
|
||
|
||
## 阶段 2 — 后端部署
|
||
|
||
### 2.1 创建 systemd 服务（blue/green/dev）
|
||
```bash
|
||
# 创建目录
|
||
mkdir -p /root/rust/rust_backend_blue
|
||
mkdir -p /root/rust/rust_backend_green
|
||
mkdir -p /root/rust/rust_backend_dev
|
||
|
||
# 注册 systemd service（从 deploy/ 目录上传）
|
||
```
|
||
|
||
### 2.2 部署 Rust 后端
|
||
```bash
|
||
# 先部署到 dev 验证
|
||
cd ASD-backend/rust-backend
|
||
deploy.sh development --remote-host 47.109.203.92
|
||
|
||
# 再部署 blue/green
|
||
deploy.sh production --remote-host 47.109.203.92
|
||
```
|
||
|
||
### 2.3 更新 deploy.sh
|
||
将默认 REMOTE_HOST 改为新服务器 IP
|
||
|
||
## 阶段 3 — 切换
|
||
|
||
### 3.1 内部验证
|
||
```bash
|
||
curl http://127.0.0.1:8080/health # dev
|
||
curl -k https://127.0.0.1:4433/health # blue
|
||
curl -k https://127.0.0.1:4434/health # green
|
||
```
|
||
|
||
### 3.2 更新 DNS
|
||
将域名指向新服务器 IP
|
||
|
||
### 3.3 验证公网访问
|
||
```bash
|
||
curl https://dev.xmclassmate.top/health
|
||
curl https://xmclassmate.top/health
|
||
```
|
||
|
||
## 阶段 4 — 清理（可选）
|
||
|
||
- 迁移 GlitchTip (Sentry)
|
||
- 旧服务器保留 1 周作为回退
|
||
- 确认无问题后关闭旧服务器
