# Jenkins CI/CD迁移实施计划

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** 将novalon-website项目从Woodpecker CI迁移到Jenkins，实现稳定可靠的CI/CD流程。

**Architecture:** 在生产服务器（139.155.109.62）上使用Docker部署Jenkins Master，通过Shell模式直接在宿主机执行构建和部署，避免创建临时Docker容器，实现零网络传输的高效构建流程。

**Tech Stack:** Jenkins LTS, Docker, Nginx, Node.js 20, npm, Git, Shell Script

---

## 前置条件

- 生产服务器：139.155.109.62
- 域名：ci.f.novalon.cn
- 项目路径：/home/novalon/docker-app/novalon-website
- SSH访问权限：root用户
- Docker已安装并运行

**Step 1: SSH连接到生产服务器**

```bash
ssh root@139.155.109.62
```

Expected: 成功登录到服务器

**Step 2: 创建Jenkins目录**

```bash
mkdir -p /home/novalon/docker-app/jenkins
cd /home/novalon/docker-app/jenkins
```

Expected: 目录创建成功

**Step 3: 创建docker-compose.yml文件**

```yaml
version: '3.8'

services:
  jenkins:
    image: jenkins/jenkins:lts
    container_name: jenkins
    restart: unless-stopped
    ports:
      - "8080:8080"
      - "50000:50000"
    volumes:
      - jenkins_home:/var/jenkins_home
      - /var/run/docker.sock:/var/run/docker.sock
      - /home/novalon/docker-app:/home/novalon/docker-app
      - /root/.ssh:/root/.ssh:ro

      interval: 30s
      timeout: 10s
      retries: 5

volumes:
  jenkins_home:
    driver: local
```

**Step 4: 创建环境变量文件**

```bash
cat > .env << 'EOF'
JENKINS_VERSION=lts
JAVA_OPTS=-Xmx2g -Xms512m -Duser.timezone=Asia/Shanghai
EOF
```

**Step 5: 创建备份脚本**

cat > backup.sh << 'EOF'
#!/bin/bash
BACKUP_DIR="/home/novalon/backups/jenkins"
DATE=$(date +%Y%m%d_%H%M%S)

mkdir -p $BACKUP_DIR

docker exec jenkins tar czf - /var/jenkins_home > $BACKUP_DIR/jenkins_backup_$DATE.tar.gz

find $BACKUP_DIR -name "jenkins_backup_*.tar.gz" -mtime +7 -delete

echo "Backup completed: jenkins_backup_$DATE.tar.gz"
EOF

chmod +x backup.sh

### Task 13: 配置邮件通知

**Files:**
- None (通过Web界面操作)

**Step 1: 配置邮件服务器**

导航到：Manage Jenkins → Configure System

找到"Extended E-mail Notification"：
- SMTP server: smtp.novalon.cn
- Default Content Type: HTML
- Default Recipients: team@novalon.cn

**Step 2: 在Jenkinsfile添加邮件通知**

```groovy
post {
    success {
        emailext (
            subject: "✅ Jenkins Build Success: ${env.JOB_NAME} #${env.BUILD_NUMBER}",
            body: """
                <h2>Build Successful</h2>
                <p><strong>Project:</strong> ${env.JOB_NAME}</p>
                <p><strong>Build Number:</strong> ${env.BUILD_NUMBER}</p>
                <p><strong>Branch:</strong> ${env.GIT_BRANCH}</p>
                <p><strong>Commit:</strong> ${env.GIT_COMMIT}</p>
                <p><a href="${env.BUILD_URL}">View Build Details</a></p>
            """,
            to: 'team@novalon.cn'
        )
    }
    
    failure {
        emailext (
            subject: "❌ Jenkins Build Failed: ${env.JOB_NAME} #${env.BUILD_NUMBER}",
            body: """
                <h2>Build Failed</h2>
                <p><strong>Project:</strong> ${env.JOB_NAME}</p>
                <p><strong>Build Number:</strong> ${env.BUILD_NUMBER}</p>
                <p><strong>Branch:</strong> ${env.GIT_BRANCH}</p>
                <p><strong>Commit:</strong> ${env.GIT_COMMIT}</p>
                <p><a href="${env.BUILD_URL}console">View Console Output</a></p>
            """,
            to: 'team@novalon.cn'
        )
    }
}
```

**Step 3: 测试邮件通知**

触发一次构建，检查邮件是否正常发送

---

### Task 14: 编写操作文档

**Files:**
- Create: `/home/novalon/docker-app/novalon-website/docs/jenkins/JENKINS_GUIDE.md`

**Step 1: 创建文档目录**

```bash
mkdir -p docs/jenkins
```

**Step 2: 编写操作指南**

```markdown
# Jenkins CI/CD 操作指南

## 访问Jenkins

- URL: https://ci.f.novalon.cn/jenkins/
- 用户名: admin
- 密码: <存储在安全位置>

## 触发构建

### 方式1: 自动触发
- 代码推送到main分支时自动触发
- Webhook配置在Git仓库设置中

### 方式2: 手动触发
1. 登录Jenkins
2. 选择Job: novalon-website
3. 点击"Build Now"

## 查看构建日志

1. 点击构建编号
2. 点击"Console Output"

## 回滚操作

如果部署失败，可以回滚到上一个版本：

\`\`\`bash
cd /home/novalon/docker-app/novalon-website
# 查看备份列表
ls -lt /home/novalon/backups/novalon-website/

# 恢复备份
tar xzf /home/novalon/backups/novalon-website/backup_YYYYMMDD_HHMMSS.tar.gz -C ./

# 重启容器
docker-compose -f docker-compose.server.yml restart
\`\`\`

## 故障排查

### 构建失败
1. 检查Console Output查看错误信息
2. 检查依赖是否正确安装
3. 检查代码是否有语法错误

### 部署失败
1. 检查容器日志: `docker-compose logs`
2. 检查端口占用: `netstat -tlnp | grep 3000`
3. 检查磁盘空间: `df -h`

### Webhook不触发
1. 检查Git仓库Webhook配置
2. 检查Jenkins是否可达
3. 查看Jenkins系统日志

## 维护操作

### 备份Jenkins数据
\`\`\`bash
cd /home/novalon/docker-app/jenkins
./backup.sh
\`\`\`

### 更新Jenkins
\`\`\`bash
cd /home/novalon/docker-app/jenkins
docker-compose pull
docker-compose up -d
\`\`\`

### 查看Jenkins日志
\`\`\`bash
docker logs jenkins -f
\`\`\`
```

**Step 3: 提交文档**

```bash
git add docs/jenkins/
git commit -m "docs: add Jenkins operation guide"
git push origin main
```

---

## Phase 4: 清理和收尾

### Task 15: 停用Woodpecker CI

**Files:**
- Modify: `/home/novalon/docker-app/novalon-website/.woodpecker.yml`

**Step 1: 备份Woodpecker配置**

```bash
cp .woodpecker.yml .woodpecker.yml.backup
```

**Step 2: 重命名Woodpecker配置**

```bash
mv .woodpecker.yml .woodpecker.yml.disabled
```

**Step 3: 提交更改**

```bash
git add .woodpecker.yml.disabled
git rm .woodpecker.yml
git commit -m "chore: disable Woodpecker CI, switch to Jenkins"
git push origin main
```

**Step 4: 验证Woodpecker不再触发**

推送代码后，确认Woodpecker不再创建新的Pipeline

---

### Task 16: 最终验证

**Files:**
- None

**Step 1: 执行完整构建流程**

```bash
# 在本地修改代码
echo "<!-- Test Jenkins CI/CD -->" >> src/app/layout.tsx

# 提交并推送
git add .
git commit -m "test: verify Jenkins CI/CD pipeline"
git push origin main
```

**Step 2: 验证自动触发**

- 检查Jenkins是否自动触发构建
- 检查构建是否成功
- 检查网站是否更新

**Step 3: 验证邮件通知**

检查是否收到构建成功邮件

**Step 4: 验证回滚功能**

```bash
# 恢复之前的代码
git reset --hard HEAD~1
git push -f origin main
```

确认Jenkins触发构建并成功回滚

## 风险评估和缓解措施

### 风险1: Jenkins容器故障
**缓解措施:**
- 定期备份Jenkins数据（每天自动备份）
- 使用Docker Volume持久化数据
- 监控容器健康状态

### 风险2: 构建失败
**缓解措施:**
- 自动备份当前版本
- 提供快速回滚机制
- 详细的错误日志和通知

### 风险3: 网络问题
**缓解措施:**
- Jenkins部署在同一台服务器，避免网络传输
- 配置超时和重试机制
- 使用本地缓存加速构建

### 风险4: 安全问题
**缓解措施:**
- 使用HTTPS加密通信
- 配置强密码和访问控制
- 定期更新Jenkins和插件
- 限制网络访问（仅允许必要IP）
