Docker 安全提醒\n \n Author: github.com/wlzh\n Version: 1.0.0\n---\n\n# VPS 安全加固 Skill\n\n> 版本: 1.0.7 | 作者: github.com/wlzh | 参考: https://x.com/gxjdian/status/2033751314208059507\n\n## 概述\n\n本 Skill 用于自动化 VPS 安全加固流程，基于「7招安全加固」最佳实践，通过 SSH 远程执行一系列安全配置命令。\n\n## ⚠️ 重要警告\n\n**在执行任何操作前，务必确保：**\n\n1. **VPS 平台防火墙已开放新的 SSH 端口** - 否则将被锁死无法登录！\n2. 如使用云服务商（AWS/阿里云/腾讯云等），需在安全组/防火墙规则中放行端口\n3. 建议先保持原 22 端口连接，新开一个终端测试新端口成功后再关闭 22\n\n## 🔴 前置条件：开启 root 密码登录\n\n**如果 VPS 不支持 root 密码登录，必须先通过 VNC/控制台开启！**\n\n很多云服务商（AWS、阿里云等）默认禁用 root 密码登录，只允许密钥登录。在运行此 Skill 前，需要先开启：\n\n**通过 VPS 平台控制台（VNC）执行以下命令：**\n\n```bash\n# 1. 开启密码认证\nsed -i 's/^#\\?PasswordAuthentication.*/PasswordAuthentication yes/' /etc/ssh/sshd_config\n\n# 2. 开启 root 登录\nsed -i 's/^#\\?PermitRootLogin.*/PermitRootLogin yes/' /etc/ssh/sshd_config\n\n# 3. 重启 SSH 服务\nsystemctl restart ssh\n\n# 4. 设置 root 密码（会提示输入两次）\npasswd root\n```\n\n**执行完成后，才能使用此 Skill 进行 SSH 登录和后续配置。**\n\n## 所需信息（执行时收集）\n\n运行此 Skill 时，需要用户提供：\n\n| 参数 | 说明 | 示例 |\n|------|------|------|\n| `VPS_IP` | VPS 的 IP 地址 | `192.168.1.100` |\n| `ROOT_PASSWORD` | root 密码 | `MyP@ssw0rd` |\n| `NEW_USER` | 新建的 sudo 用户名 | `admin` |\n| `NEW_USER_PASSWORD` | 新用户密码 | `UserP@ss123` |\n| `SSH_PORT` | 新的 SSH 端口 | `22222` |\n\n## 执行流程\n\n### Phase 0: 环境检查\n\n```bash\n# 检查本地是否安装 sshpass（用于自动输入密码）\nwhich sshpass || echo \"需要安装 sshpass: brew install sshpass 或 apt install sshpass\"\n```\n\n### Phase 1: SSH 连接与系统检测\n\n1. **检测 root 密码登录是否开启**\n2. **检测 Ubuntu 版本**（影响 SSH 配置方式）\n3. **登录后执行系统更新**\n\n```bash\n# 检测 Ubuntu 版本\nlsb_release -a\n\n# 更新系统\napt update && apt upgrade -y\n\n# 检查必要工具\nwhich ufw || apt install ufw -y\nwhich sudo || apt install sudo -y\nwhich fail2ban-client || apt install fail2ban -y\n```\n\n**Ubuntu 版本与 SSH 配置方式：**\n\n| Ubuntu 版本 | SSH 配置方式 |\n|-------------|-------------|\n| 22.10, 23.04, 23.10 | socket 激活，需配置 `/etc/systemd/system/ssh.socket.d/` |\n| 24.04+ | 直接修改 `/etc/ssh/sshd_config` 或 `sshd_config.d/` |\n\n### Phase 2: 创建 Sudo 用户（第一招）\n\n```bash\n# 创建用户\nuseradd -m -G sudo -s /bin/bash ${NEW_USER}\n\n# 设置密码\necho \"${NEW_USER}:${NEW_USER_PASSWORD}\" | chpasswd\n\n# 验证用户创建成功\nid ${NEW_USER}\n```\n\n### Phase 3: 配置 SSH 安全设置（第二招）\n\n**方式A：Ubuntu 24.04+ / 传统方式**\n\n创建专用配置文件 `/etc/ssh/sshd_config.d/99-hardening.conf`：\n\n```ssh\n# VPS Security Hardening - generated by vps-security-hardening skill\n# Author: github.com/wlzh\n# Version: 1.0.0\n\nPort ${SSH_PORT}\nPermitRootLogin prohibit-password\nPasswordAuthentication yes\nPubkeyAuthentication yes\nMaxAuthTries 3\nClientAliveInterval 300\nClientAliveCountMax 2\n```\n\n**方式B：Ubuntu 22.10/23.04/23.10（socket 激活）**\n\n```bash\n# 创建 socket 覆盖配置\nmkdir -p /etc/systemd/system/ssh.socket.d\ncat > /etc/systemd/system/ssh.socket.d/listen.conf << EOF\n[Socket]\nListenStream=\nListenStream=${SSH_PORT}\nEOF\n\n# 禁用 socket 激活，改用传统服务\nsystemctl disable --now ssh.socket\nsystemctl enable --now ssh.service\n```\n\n**配置说明：**\n- `Port`: 自定义 SSH 端口，避开默认 22\n- `PermitRootLogin prohibit-password`: root 仅允许密钥登录（比 without-password 更严格）\n- `PasswordAuthentication yes`: 普通用户允许密码登录（配置密钥后可改为 no）\n- `PubkeyAuthentication yes`: 启用密钥认证\n- `MaxAuthTries 3`: 最多尝试 3 次认证\n- `ClientAliveInterval/CountMax`: 5 分钟无活动断开\n\n### Phase 4: 配置 Fail2ban（第三招）\n\n```bash\n# 安装 fail2ban\napt install fail2ban -y\n\n# 创建自定义配置\ncat > /etc/fail2ban/jail.local << 'EOF'\n[sshd]\nignoreip = 127.0.0.1/8\nenabled = true\nfilter = sshd\nport = ${SSH_PORT}\nmaxretry = 5\nfindtime = 300\nbantime = 600\nlogpath = /var/log/auth.log\naction = %(action_)s\nEOF\n\n# 启动服务\nsystemctl enable fail2ban\nsystemctl start fail2ban\n```\n\n**配置说明：**\n- `ignoreip`: 白名单 IP，不会被封\n- `maxretry`: 允许失败 5 次\n- `findtime`: 5 分钟内\n- `bantime`: 封禁 10 分钟（设为 -1 永久封禁，但不推荐）\n\n### Phase 5: 验证 SSH 配置\n\n```bash\n# 检查配置语法\nsshd -t\n\n# 验证配置生效（重启前）\nsshd -T | grep -iE \"^(port|permitrootlogin|passwordauthentication|pubkeyauthentication) \"\n\n# 预期输出：\n# port ${SSH_PORT}\n# permitrootlogin prohibit-password\n# passwordauthentication yes\n# pubkeyauthentication yes\n```\n\n### Phase 6: 配置 UFW 防火墙（第六招）\n\n```bash\n# 设置默认策略\nufw default deny incoming\nufw default allow outgoing\n\n# 允许新 SSH 端口（必须在启用前配置！）\nufw allow ${SSH_PORT}/tcp comment 'SSH custom port'\n\n# 如果有网站服务\n# ufw allow 80/tcp\n# ufw allow 443/tcp\n\n# 启用防火墙\nufw --force enable\n\n# 删除默认 22 端口（确认新端口可用后）\nufw delete allow 22/tcp 2>/dev/null || ufw status numbered\n\n# 查看状态\nufw status verbose\n```\n\n### Phase 7: 重启服务\n\n```bash\n# 重载配置\nsystemctl daemon-reload\nsystemctl restart ssh.service\nsystemctl restart fail2ban\n\n# 验证服务状态\nsystemctl is-active ssh.service\nsystemctl is-active fail2ban\n```\n\n### Phase 8: SSH 登录通知（第五招，可选）\n\n如需配置登录通知（企业微信/Telegram/钉钉）：\n\n```bash\n# 编辑 PAM 配置\nvim /etc/pam.d/sshd\n# 添加：session optional pam_exec.so /usr/local/bin/notify_ssh_login.sh\n\n# 创建通知脚本\nvim /usr/local/bin/notify_ssh_login.sh\nchmod +x /usr/local/bin/notify_ssh_login.sh\n```\n\n**企业微信通知脚本示例：**\n\n```bash\n#!/bin/bash\nif [ \"$PAM_TYPE\" != \"open_session\" ]; then\n exit 0\nfi\n\nip=$PAM_RHOST\ndate=$(date +\"%e %b %Y, %a %r\")\nname=$PAM_USER\nwebhook_url=\"https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=你的webhook密钥\"\n\ncurl -s -X POST \"$webhook_url\" \\\n -H \"Content-Type: application/json\" \\\n -d \"{\n \\\"msgtype\\\": \\\"markdown\\\",\n \\\"markdown\\\": {\n \\\"content\\\": \\\"**SSH登录提醒**\\n> 登录用户: $name\\n> 客户端IP: $ip\\n> 登录时间: $date\\\"\n }\n }\"\n```\n\n### Phase 9: 生成报告\n\n执行完成后，生成包含以下内容的报告：\n\n```\n════════════════════════════════════════════════════════════\n VPS 安全加固报告\n════════════════════════════════════════════════════════════\n执行时间: $(date)\nVPS IP: ${VPS_IP}\n系统版本: $(lsb_release -ds)\n\n[✓] 系统更新: apt update && apt upgrade 完成\n[✓] 新用户: ${NEW_USER} 已创建并加入 sudo 组\n[✓] SSH 端口: ${SSH_PORT}\n[✓] Root 登录: 仅允许密钥登录 (prohibit-password)\n[✓] 密码认证: 已启用（普通用户）\n[✓] Fail2ban: 已安装并启动\n[✓] UFW 防火墙: 已启用\n\n防火墙状态:\n$(ufw status verbose)\n\nFail2ban 状态:\n$(fail2ban-client status sshd)\n\nSSH 配置验证:\n$(sshd -T | grep -iE \"^(port|permitrootlogin|passwordauthentication) \")\n\n════════════════════════════════════════════════════════════\n 登录信息\n════════════════════════════════════════════════════════════\n新登录命令: ssh -p ${SSH_PORT} ${NEW_USER}@${VPS_IP}\n\n⚠️ 重要提醒:\n1. 请确保 VPS 平台防火墙已开放端口 ${SSH_PORT}\n2. 建议配置 SSH 密钥登录后禁用密码认证\n3. 保存好新用户密码: ${NEW_USER_PASSWORD}\n4. 如使用 Docker，注意配置端口映射安全（见第七招）\n════════════════════════════════════════════════════════════\n```\n\n## 执行脚本\n\n完整的自动化脚本见 `scripts/harden-vps.sh`，支持以下参数：\n\n```bash\n./scripts/harden-vps.sh \\\n --ip \\\n --root-pass \\\n --user \\\n --user-pass \\\n --port \n```\n\n## Docker 安全提醒（第七招）\n\n如果 VPS 上运行 Docker，需要注意：\n\n1. **内部服务不暴露端口** - 数据库、Redis 等只在容器内部通信\n ```yaml\n services:\n redis:\n image: redis:alpine\n # 不需要 ports 配置！\n ```\n\n2. **需要反代的服务只监听 127.0.0.1**\n ```yaml\n services:\n app:\n ports:\n - \"127.0.0.1:3000:3000\" # 只在本地监听\n ```\n\n3. **需要公网访问的服务才暴露端口**\n ```yaml\n services:\n web:\n ports:\n - \"80:80\"\n - \"443:443\"\n ```\n\n**原因**：Docker 会直接修改 iptables 规则，绕过 UFW！\n\n## 常见问题\n\n### Q: sshpass 未安装怎么办？\n\nA: 手动安装：\n- macOS: `brew install hudochenkov/sshpass/sshpass`\n- Ubuntu/Debian: `sudo apt install sshpass -y`\n- CentOS/RHEL: `sudo yum install sshpass -y`\n\n### Q: root 密码登录未开启怎么办？\n\nA: 需要通过 VPS 控制台（VNC/控制台）执行：\n\n```bash\nsed -i 's/^#\\?PasswordAuthentication.*/PasswordAuthentication yes/' /etc/ssh/sshd_config\nsed -i 's/^#\\?PermitRootLogin.*/PermitRootLogin yes/' /etc/ssh/sshd_config\nsystemctl restart ssh\npasswd root # 设置 root 密码\n```\n\n### Q: 被防火墙锁死怎么办？\n\nA: 通过 VPS 平台控制台（VNC）登录，执行：\n\n```bash\nufw disable\n# 或添加规则\nufw allow 22/tcp\nufw allow ${SSH_PORT}/tcp\n```\n\n### Q: 如何配置 SSH 密钥登录？\n\n```bash\n# 本地生成密钥\nssh-keygen -t ed25519 -C \"your@email.com\"\n\n# 复制公钥到服务器\nssh-copy-id -p ${SSH_PORT} ${NEW_USER}@${VPS_IP}\n\n# 测试密钥登录成功后，禁用密码认证\n# 修改 /etc/ssh/sshd_config.d/99-hardening.conf\nPasswordAuthentication no\nsystemctl restart ssh\n```\n\n## 安全检查清单\n\n- [ ] 系统已更新 (`apt update && apt upgrade`)\n- [ ] sudo 用户已创建\n- [ ] SSH 端口已修改\n- [ ] root 密码登录已禁用\n- [ ] Fail2ban 已安装并运行\n- [ ] UFW 防火墙已配置\n- [ ] 云平台防火墙已开放新端口\n- [ ] SSH 密钥已配置（推荐）\n- [ ] SSH 登录通知已配置（可选）\n- [ ] Docker 端口映射已检查（如适用）\n\n## 版本历史\n\n- **v1.0.0** (2026-03-17): 初始版本\n - 7 招安全加固完整实现\n - 支持 Ubuntu 多版本检测\n - Fail2ban 自动安装配置\n - SSH 登录通知支持\n - Docker 安全提醒\n","tagline":"VPS 安全加固自动化 Skill。通过 SSH 登录 VPS 并执行完整的安全策略配置。\n\n触发场景：\n- \"加固VPS安全\"、\"VPS安全配置\"、\"新VPS初始化\"\n- \"配置SSH安全\"、\"修改SSH端口\"、\"禁用root密码登录\"\n- \"VPS安全加固\"、\"服务器安全设置\"、\"hardening\"\n\n功能（7招安全加固）：\n1. 创建 sudo 用户，禁用 root 密码登录\n2. 修改 SSH 端口（支持 Ubuntu 不同版本）\n3.
