The backward-compat redirect from www.ityb.me/careerbot/* to career.ityb.me/careerbot/* has been removed per user request. Now all /careerbot paths on the main domain return 404, except /careerbot/uploads/* which is served by branch1's secondary mount so trunk-uploaded photo URLs still render on branch1 pages.

|
||
|
||
## 5. 常用运维命令
|
||
|
||
### 5.1 服务管理
|
||
|
||
```bash
|
||
# ── CareerBot ──
|
||
sudo systemctl status careerbot # 查看状态
|
||
sudo systemctl restart careerbot # 重启
|
||
sudo systemctl stop careerbot # 停止
|
||
sudo systemctl start careerbot # 启动
|
||
sudo journalctl -u careerbot -f # 实时查看日志
|
||
sudo journalctl -u careerbot --since "1 hour ago" # 查看最近1小时日志
|
||
|
||
# ── Nginx ──
|
||
sudo systemctl status nginx
|
||
sudo systemctl reload nginx # 重载配置（不中断连接）
|
||
sudo systemctl restart nginx # 重启
|
||
sudo nginx -t # 测试配置文件语法
|
||
|
||
# ── Gitea ──
|
||
sudo systemctl status gitea
|
||
sudo systemctl restart gitea
|
||
sudo journalctl -u gitea -f
|
||
```
|
||
|
||
### 5.2 代码更新部署
|
||
|
||
**从本地推送代码并部署到线上（标准流程）：**
|
||
|
||
```bash
|
||
# 1. 本地：提交并推送到 Gitea
|
||
cd D:/Files/Projects/VibeCoding/CareerBot
|
||
git add .
|
||
git commit -m "描述改动"
|
||
git push origin main
|
||
|
||
# 2. 线上：拉取并重启
|
||
ssh ecs "cd ~/apps/CareerBot && git pull && sudo systemctl restart careerbot"
|
||
```
|
||
|
||
**一键部署脚本（在本地执行）：**
|
||
```bash
|
||
ssh ecs "cd ~/apps/CareerBot && git pull origin main && sudo systemctl restart careerbot && sleep 2 && sudo systemctl is-active careerbot"
|
||
```
|
||
|
||
### 5.3 数据库操作
|
||
|
||
```bash
|
||
# 连接到 SQLite 数据库
|
||
ssh ecs "cd ~/apps/CareerBot && sqlite3 careerbot.db"
|
||
|
||
# 常用 SQL
|
||
.tables # 查看所有表
|
||
SELECT * FROM admin_user; # 查看管理员
|
||
SELECT token, note, max_questions, used_questions, is_active FROM access_token; # 查看令牌
|
||
SELECT * FROM recruiter_message ORDER BY created_at DESC LIMIT 10; # 最近招聘消息
|
||
SELECT COUNT(*) FROM chat_history; # 对话记录总数
|
||
.quit # 退出
|
||
```
|
||
|
||
### 5.4 系统监控
|
||
|
||
```bash
|
||
# 查看内存使用
|
||
ssh ecs "free -h"
|
||
|
||
# 查看磁盘使用
|
||
ssh ecs "df -h /"
|
||
|
||
# 查看各服务内存占用
|
||
ssh ecs "ps aux --sort=-rss | head -10"
|
||
|
||
# 查看端口监听
|
||
ssh ecs "ss -tlnp"
|
||
```
|
||

|
||
## 6. 配置文件详情
|
||
|
||
### 6.1 CareerBot systemd 服务
|
||
|
||
**Trunk（main 分支）**：`/etc/systemd/system/careerbot.service`
|
||
```ini
|
||
[Unit]
|
||
Description=CareerBot Web Application
|
||
After=network.target
|
||
|
||
[Service]
|
||
Type=simple
|
||
User=deploy
|
||
WorkingDirectory=/home/deploy/apps/CareerBot
|
||
ExecStart=/home/deploy/apps/CareerBot/venv/bin/uvicorn app.main:app --host 127.0.0.1 --port 8000
|
||
Restart=always
|
||
RestartSec=5
|
||
Environment=PATH=/home/deploy/apps/CareerBot/venv/bin:/usr/bin
|
||
|
||
[Install]
|
||
WantedBy=multi-user.target
|
||
```
|
||
|
||
**Branch1（branch1 分支，共享 trunk 数据）**：`/etc/systemd/system/careerbot-branch1.service`
|
||
```ini
|
||
[Unit]
|
||
Description=CareerBot branch1 (display-only, shared DB with trunk)
|
||
After=network.target
|
||
|
||
[Service]
|
||
Type=simple
|
||
User=deploy
|
||
WorkingDirectory=/home/deploy/apps/CareerBot-branch1
|
||
ExecStart=/home/deploy/apps/CareerBot-branch1/venv/bin/uvicorn app.main:app --host 127.0.0.1 --port 8001
|
||
Restart=always
|
||
Environment=PATH=/home/deploy/apps/CareerBot-branch1/venv/bin:/usr/bin
|
||
Environment=DATABASE_URL=sqlite:////home/deploy/apps/CareerBot/careerbot.db
|
||
Environment=UPLOAD_DIR=/home/deploy/apps/CareerBot/uploads
|
||
Environment=BASE_PATH=
|
||
|
||
[Install]
|
||
WantedBy=multi-user.target
|
||
```
|
||
|
||
关键差异：
|
||
- **端口**：trunk 用 8000，branch1 用 8001
|
||
- **数据共享**：branch1 通过 `DATABASE_URL` 和 `UPLOAD_DIR` 环境变量指向 trunk 的数据库和上传目录
|
||
- **BASE_PATH**：branch1 设置为空串，应用部署在根路径
|
||
- **FAB 显示**：branch1 的 `templates/index.html` 已修改，对话按钮 `style="display:none;"`
|
||
- `Restart=always`：崩溃后自动重启
|
||
|
||
### 6.2 Nginx 站点配置
|
||
|
||
文件：`/etc/nginx/sites-available/careerbot.conf`（含三段 server block + certbot 自动追加的 HTTPS 块）
|
||
|
||
```nginx
|
||
# ===== TRUNK: career.ityb.me (完整版，/careerbot/ 子路径) =====
|
||
server {
|
||
server_name career.ityb.me;
|
||
client_max_body_size 10M;
|
||
|
||
location /careerbot/ {
|
||
proxy_pass http://127.0.0.1:8000/careerbot/;
|
||
proxy_set_header Host $host;
|
||
proxy_set_header X-Real-IP $remote_addr;
|
||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||
proxy_set_header X-Forwarded-Proto $scheme;
|
||
proxy_buffering off; proxy_cache off; proxy_read_timeout 300s;
|
||
}
|
||
location = / { return 302 /careerbot/; }
|
||
|
||
listen 443 ssl; # by certbot
|
||
ssl_certificate /etc/letsencrypt/live/career.ityb.me/fullchain.pem;
|
||
ssl_certificate_key /etc/letsencrypt/live/career.ityb.me/privkey.pem;
|
||
}
|
||
|
||
# ===== BRANCH1: www.ityb.me + ityb.me (展示版，根路径) =====
|
||
server {
|
||
listen 80;
|
||
server_name www.ityb.me ityb.me;
|
||
return 301 https://$host$request_uri;
|
||
}
|
||
server {
|
||
listen 443 ssl;
|
||
server_name www.ityb.me ityb.me;
|
||
client_max_body_size 10M;
|
||
|
||
ssl_certificate /etc/letsencrypt/live/www.ityb.me/fullchain.pem;
|
||
ssl_certificate_key /etc/letsencrypt/live/www.ityb.me/privkey.pem;
|
||
|
||
location / {
|
||
proxy_pass http://127.0.0.1:8001/; # branch1
|
||
proxy_set_header Host $host;
|
||
proxy_set_header X-Real-IP $remote_addr;
|
||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||
proxy_set_header X-Forwarded-Proto $scheme;
|
||
proxy_buffering off; proxy_cache off; proxy_read_timeout 300s;
|
||
}
|
||
}
|
||
|
||
# ===== IP 直连（向后兼容，HTTP only） =====
|
||
server {
|
||
listen 80 default_server;
|
||
server_name 39.106.14.107;
|
||
client_max_body_size 10M;
|
||
|
||
location /careerbot/ {
|
||
proxy_pass http://127.0.0.1:8000/careerbot/;
|
||
# ... 同 trunk ...
|
||
}
|
||
location = / { return 302 /careerbot/; }
|
||
}
|
||
```
|
||
|
||
关键配置说明：
|
||
- **双域双实例**：career 子域名走 trunk（:8000），主域名走 branch1（:8001）
|
||
- **SSL 证书**：`career.ityb.me` 和 `www.ityb.me+ityb.me` 分别独立证书（均由 certbot 自动申请续期）
|
||
- **主域路径隔离**：`www.ityb.me/careerbot/*` 返回 404（nginx 层不做任何特殊处理，请求透传到 branch1 后端，branch1 没有 /careerbot 前缀路由因此 404）；仅 `/careerbot/uploads/*` 能命中 branch1 的二级挂载，用于显示 trunk 管理员上传的头像
|
||
- `proxy_buffering off` + `proxy_cache off`：**必须关闭**，否则 SSE 流式对话无法实时返回
|
||
- `proxy_read_timeout 300s`：LLM 长回复可能需要较长时间
|
||
|
||
### 6.3 Gitea 站点配置
|
||
|
||
文件：`/etc/nginx/sites-available/gitea.conf`（HTTPS 部分由 certbot 自动生成）
|
||
```nginx
|
||
server {
|
||
listen 80;
|
||
server_name git.ityb.me;
|
||
client_max_body_size 512M;
|
||
|
||
location / {
|
||
proxy_pass http://127.0.0.1:3000;
|
||
proxy_set_header Host $host;
|
||
proxy_set_header X-Real-IP $remote_addr;
|
||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||
proxy_set_header X-Forwarded-Proto $scheme;
|
||
proxy_read_timeout 300s;
|
||
}
|
||
|
||
# certbot 自动追加 443 监听块 + 80→443 重定向
|
||
listen 443 ssl;
|
||
ssl_certificate /etc/letsencrypt/live/git.ityb.me/fullchain.pem;
|
||
ssl_certificate_key /etc/letsencrypt/live/git.ityb.me/privkey.pem;
|
||
}
|
||
```
|
||
|
||
关键说明：
|
||
- `client_max_body_size 512M`：支持大仓库 push/pull
|
||
- Gitea 仍在本机 3000 端口监听，Nginx 反向代理到 443（HTTPS）
|
||
- 端口 3000 保持对外开放作为备用访问方式
|
||
- 对应 Gitea 配置 `/etc/gitea/app.ini`：`ROOT_URL=https://git.ityb.me/`、`DOMAIN=git.ityb.me`、`SSH_DOMAIN=git.ityb.me`
|
||
|
||
### 6.3 防火墙规则
|
||
|
||
```bash
|
||
# 查看当前规则
|
||
sudo firewall-cmd --list-ports
|
||
# 输出: 22/tcp 80/tcp 443/tcp 3000/tcp
|
||
|
||
# 添加新端口（如未来部署新项目）
|
||
sudo firewall-cmd --permanent --add-port=PORT/tcp
|
||
sudo firewall-cmd --reload
|
||
```
|
||
|
||
> **注意**：开放端口还需要在阿里云控制台的**安全组**中同步添加入方向规则，否则外部仍无法访问。
|
||
|
||
---
|
||
|
||
## 7. 备份策略
|
||
|
||
### 7.1 数据库备份
|
||
|
||
CareerBot 的所有业务数据存储在 SQLite 文件中：
|
||
|
||
```bash
|
||
# 手动备份
|
||
ssh ecs "cp ~/apps/CareerBot/careerbot.db ~/apps/CareerBot/careerbot.db.bak.$(date +%Y%m%d)"
|
||
|
||
# 下载到本地
|
||
scp ecs:~/apps/CareerBot/careerbot.db ./careerbot_backup_$(date +%Y%m%d).db
|
||
```
|
||
|
||
### 7.2 Gitea 数据备份
|
||
|
||
```bash
|
||
# Gitea 数据和仓库
|
||
ssh ecs "sudo tar czf /tmp/gitea-backup.tar.gz /var/lib/gitea /etc/gitea"
|
||
scp ecs:/tmp/gitea-backup.tar.gz ./gitea-backup.tar.gz
|
||
```
|
||
|
||
### 7.3 需要备份的关键文件
|
||
|
||
| 文件/目录 | 说明 | 重要程度 |
|
||
|-----------|------|---------|
|
||
| `~/apps/CareerBot/careerbot.db` | CareerBot 全部业务数据 | **极高** |
|
||
| `~/apps/CareerBot/uploads/` | 用户上传的文件 | 高 |
|
||
| `/var/lib/gitea/` | Gitea 所有仓库和数据 | **极高** |
|
||
| `/etc/gitea/app.ini` | Gitea 配置 | 中 |
|
||
| `/etc/nginx/sites-available/` | Nginx 站点配置 | 中 |
|
||
| `/etc/systemd/system/careerbot.service` | 服务配置 | 低（可重建） |
|
||
|
||
---
|
||
|
||
## 8. 故障排查
|
||
|
||
### 8.1 CareerBot 无法访问
|
||
|
||
```bash
|
||
# 1. 检查服务状态
|
||
sudo systemctl status careerbot
|
||
|
||
# 2. 查看错误日志
|
||
sudo journalctl -u careerbot --since "10 min ago"
|
||
|
||
# 3. 检查端口
|
||
ss -tlnp | grep 8000
|
||
|
||
# 4. 检查 Nginx
|
||
sudo nginx -t
|
||
sudo systemctl status nginx
|
||
|
||
# 5. 手动启动测试
|
||
cd ~/apps/CareerBot
|
||
source venv/bin/activate
|
||
uvicorn app.main:app --host 127.0.0.1 --port 8000
|
||
```
|
||
|
||
### 8.2 AI 对话不工作
|
||
|
||
- 检查管理后台（`http://www.ityb.me/careerbot/admin/llm-config`）LLM Config 是否已配置（API URL、API Key、Model Name）
|
||
- 点击 "Test Connection" 测试连通性
|
||
- 确认 ECS 能访问外网：`curl https://api.deepseek.com`
|
||
|
||
### 8.3 Gitea 无法访问
|
||
|
||
```bash
|

### 8.4 磁盘/内存不足
|
||
|
||
```bash
|
||
# 查看磁盘
|
||
df -h /
|
||
|
||
# 清理日志
|
||
sudo journalctl --vacuum-time=7d
|
||
|
||
# 查看内存
|
||
free -h
|
||
|
||
# 查看占用最多的进程
|
||
ps aux --sort=-rss | head -10
|
||
```

## 9. 新项目部署指南
|
||
|
||
后续在同一台 ECS 上部署新项目的标准流程：
|
||
|
||
1. **Gitea 上创建仓库**：`https://git.ityb.me` → New Repository
|
||
|
||
2. **本地推送代码**
|
||
3. **ECS 上克隆并配置**：
|
||
```bash
|
||
cd ~/apps
|
||
git clone https://git.ityb.me/ln0422/新项目.git
|
||
# 安装依赖、初始化等
|
||
```
|
||
|
||
4. **创建 systemd 服务**（参考 careerbot.service，注意更换端口号）
|
||
|
||
5. **添加 Nginx 站点配置**（在同一个 `careerbot.conf` 文件或新建独立 conf 文件中，添加新的 `location /新路径/` 块）：
|
||
```bash
|
||
sudo vim /etc/nginx/sites-available/新项目.conf
|
||
sudo ln -s /etc/nginx/sites-available/新项目.conf /etc/nginx/sites-enabled/
|
||
sudo nginx -t && sudo systemctl reload nginx
|
||
```
|
||
> 建议参考 CareerBot 的子路径部署模式：`location /新路径/ { proxy_pass http://127.0.0.1:新端口/新路径/; }`
|
||
|
||
6. **如需新端口**：防火墙 + 阿里云安全组同步放行
|
||

||
## 10. 安全注意事项
|
||
|
||
1. **SSH 密钥**：本地私钥 `~/.ssh/id_ed25519` 请妥善保管，丢失需重新生成并更新服务器
|
||
2. **Gitea 端口**：3000 端口对外开放，建议设置强密码，或后续通过 Nginx 代理并限制访问
|
||
3. **数据库文件**：`careerbot.db` 不应对外暴露，uvicorn 仅监听 127.0.0.1 已确保安全
|
||
4. **定期更新**：定期执行 `sudo dnf update -y` 更新系统安全补丁
|
||
5. **HTTPS**：域名 `ityb.me` 已绑定，建议配置 Let's Encrypt SSL 证书（`certbot --nginx -d www.ityb.me -d ityb.me`）
