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。
在执行任何操作前，务必确保：
如果 VPS 不支持 root 密码登录，必须先通过 VNC/控制台 开启！
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：
通过 VPS 平台控制台（VNC）执行以下命令：
# 1. 开启密码认证
sed -i 's/^#\?PasswordAuthentication.*/PasswordAuthentication yes/' /etc/ssh/sshd_config
# 2. 开启 root 登录
sed -i 's/^#\?PermitRootLogin.*/PermitRootLogin yes/' /etc/ssh/sshd_config
# 3. 重启 SSH 服务
systemctl restart ssh
# 4. 设置 root 密码（会提示输入两次）
passwd root
执行完成后，才能使用此 Skill 进行 SSH 登录和后续配置。
运行此 Skill 时，需要用户提供：
| 参数 | 说明 | 示例 |
|---|---|---|
VPS_IP | VPS 的 IP 地址 | 192.168.1.100 |
ROOT_PASSWORD | root 密码 | MyP@ssw0rd |
NEW_USER | 新建的 sudo 用户名 | admin |
NEW_USER_PASSWORD | 新用户密码 | UserP@ss123 |
SSH_PORT | 新的 SSH 端口 | 22222 |
# 检查本地是否安装 sshpass（用于自动输入密码）
which sshpass || echo "需要安装 sshpass: brew install sshpass 或 apt install sshpass"
# 检测 Ubuntu 版本
lsb_release -a
# 更新系统
apt update && apt upgrade -y
# 检查必要工具
which ufw || apt install ufw -y
which sudo || apt install sudo -y
which fail2ban-client || apt install fail2ban -y
Ubuntu 版本与 SSH 配置方式：
| Ubuntu 版本 | SSH 配置方式 |
|---|---|
| 22.10, 23.04, 23.10 | socket 激活，需配置 /etc/systemd/system/ssh.socket.d/ |
| 24.04+ | 直接修改 /etc/ssh/sshd_config 或 sshd_config.d/ |
# 创建用户
useradd -m -G sudo -s /bin/bash ${NEW_USER}
# 设置密码
echo "${NEW_USER}:${NEW_USER_PASSWORD}" | chpasswd
# 验证用户创建成功
id ${NEW_USER}
方式A：Ubuntu 24.04+ / 传统方式
创建专用配置文件 /etc/ssh/sshd_config.d/99-hardening.conf：
# VPS Security Hardening - generated by vps-security-hardening skill
# Author: github.com/wlzh
# Version: 1.0.0
Port ${SSH_PORT}
PermitRootLogin prohibit-password
PasswordAuthentication yes
PubkeyAuthentication yes
MaxAuthTries 3
ClientAliveInterval 300
ClientAliveCountMax 2
方式B：Ubuntu 22.10/23.04/23.10（socket 激活）
# 创建 socket 覆盖配置
mkdir -p /etc/systemd/system/ssh.socket.d
cat > /etc/systemd/system/ssh.socket.d/listen.conf << EOF
[Socket]
ListenStream=
ListenStream=${SSH_PORT}
EOF
# 禁用 socket 激活，改用传统服务
systemctl disable --now ssh.socket
systemctl enable --now ssh.service
配置说明：
Port: 自定义 SSH 端口，避开默认 22PermitRootLogin prohibit-password: root 仅允许密钥登录（比 without-password 更严格）PasswordAuthentication yes: 普通用户允许密码登录（配置密钥后可改为 no）PubkeyAuthentication yes: 启用密钥认证MaxAuthTries 3: 最多尝试 3 次认证ClientAliveInterval/CountMax: 5 分钟无活动断开# 安装 fail2ban
apt install fail2ban -y
# 创建自定义配置
cat > /etc/fail2ban/jail.local << 'EOF'
[sshd]
ignoreip = 127.0.0.1/8
enabled = true
filter = sshd
port = ${SSH_PORT}
maxretry = 5
findtime = 300
bantime = 600
logpath = /var/log/auth.log
action = %(action_)s
EOF
# 启动服务
systemctl enable fail2ban
systemctl start fail2ban
配置说明：
ignoreip: 白名单 IP，不会被封maxretry: 允许失败 5 次findtime: 5 分钟内bantime: 封禁 10 分钟（设为 -1 永久封禁，但不推荐）# 检查配置语法
sshd -t
# 验证配置生效（重启前）
sshd -T | grep -iE "^(port|permitrootlogin|passwordauthentication|pubkeyauthentication) "
# 预期输出：
# port ${SSH_PORT}
# permitrootlogin prohibit-password
# passwordauthentication yes
# pubkeyauthentication yes
# 设置默认策略
ufw default deny incoming
ufw default allow outgoing
# 允许新 SSH 端口（必须在启用前配置！）
ufw allow ${SSH_PORT}/tcp comment 'SSH custom port'
# 如果有网站服务
# ufw allow 80/tcp
# ufw allow 443/tcp
# 启用防火墙
ufw --force enable
# 删除默认 22 端口（确认新端口可用后）
ufw delete allow 22/tcp 2>/dev/null || ufw status numbered
# 查看状态
ufw status verbose
# 重载配置
systemctl daemon-reload
systemctl restart ssh.service
systemctl restart fail2ban
# 验证服务状态
systemctl is-active ssh.service
systemctl is-active fail2ban
如需配置登录通知（企业微信/Telegram/钉钉）：
# 编辑 PAM 配置
vim /etc/pam.d/sshd
# 添加：session optional pam_exec.so /usr/local/bin/notify_ssh_login.sh
# 创建通知脚本
vim /usr/local/bin/notify_ssh_login.sh
chmod +x /usr/local/bin/notify_ssh_login.sh
企业微信通知脚本示例：
#!/bin/bash
if [ "$PAM_TYPE" != "open_session" ]; then
exit 0
fi
ip=$PAM_RHOST
date=$(date +"%e %b %Y, %a %r")
name=$PAM_USER
webhook_url="https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=你的webhook密钥"
curl -s -X POST "$webhook_url" \
-H "Content-Type: application/json" \
-d "{
\"msgtype\": \"markdown\",
\"markdown\": {
\"content\": \"**SSH登录提醒**\n> 登录用户: $name\n> 客户端IP: $ip\n> 登录时间: $date\"
}
}"
执行完成后，生成包含以下内容的报告：

--user-pass <NEW_USER_PASSWORD> \
--port <SSH_PORT>
如果 VPS 上运行 Docker，需要注意：
内部服务不暴露端口 - 数据库、Redis 等只在容器内部通信
services:
redis:
image: redis:alpine
# 不需要 ports 配置！
需要反代的服务只监听 127.0.0.1
services:
app:
ports:
- "127.0.0.1:3000:3000" # 只在本地监听
需要公网访问的服务才暴露端口
services:
web:
ports:
- "80:80"
- "443:443"
原因：Docker 会直接修改 iptables 规则，绕过 UFW！
A: 手动安装：
brew install hudochenkov/sshpass/sshpasssudo apt install sshpass -ysudo yum install sshpass -yA: 需要通过 VPS 控制台（VNC/控制台）执行：
sed -i 's/^#\?PasswordAuthentication.*/PasswordAuthentication yes/' /etc/ssh/sshd_config
sed -i 's/^#\?PermitRootLogin.*/PermitRootLogin yes/' /etc/ssh/sshd_config
systemctl restart ssh
passwd root # 设置 root 密码
A: 通过 VPS 平台控制台（VNC）登录，执行：

# VPS 安全加固 Skill
> 版本: 1.0.7 | 作者: github.com/wlzh | 参考: https://x.com/gxjdian/status/2033751314208059507
## 概述
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。
## ⚠️ 重要警告
**在执行任何操作前，务必确保：**
1. **VPS 平台防火墙已开放新的 SSH 端口** - 否则将被锁死无法登录！
2. 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
3. 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
## 🔴 前置条件：开启 root 密码登录
**如果 VPS 不支持 root 密码登录，必须先通过 VNC/控制台 开启！**
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：
**通过 VPS 平台控制台（VNC）执行以下命令：**
```bash
# 1. 开启密码认证
sed -i 's/^#\?PasswordAuthentication.*/PasswordAuthentication yes/' /etc/ssh/sshd_config
# 2. 开启 root 登录
sed -i 's/^#\?PermitRootLogin.*/PermitRootLogin yes/' /etc/ssh/sshd_config
# 3. 重启 SSH 服务
systemctl restart ssh
# 4. 设置 root 密码（会提示输入两次）
passwd root
```
**执行完成后，才能使用此 Skill 进行 SSH 登录和后续配置。**
## 所需信息（执行时收集）
运行此 Skill 时，需要用户提供：
| 参数 | 说明 | 示例 |
|------|------|------|
| `VPS_IP` | VPS 的 IP 地址 | `192.168.1.100` |
| `ROOT_PASSWORD` | root 密码 | `MyP@ssw0rd` |
| `NEW_USER` | 新建的 sudo 用户名 | `admin` |
| `NEW_USER_PASSWORD` | 新用户密码 | `UserP@ss123` |
| `SSH_PORT` | 新的 SSH 端口 | `22222` |
## 执行流程
### Phase 0: 环境检查
```bash
# 检查本地是否安装 sshpass（用于自动输入密码）
which sshpass || echo "需要安装 sshpass: brew install sshpass 或 apt install sshpass"
```
### Phase 1: SSH 连接与系统检测
1. **检测 root 密码登录是否开启**
2. **检测 Ubuntu 版本**（影响 SSH 配置方式）
3. **登录后执行系统更新**
```bash
# 检测 Ubuntu 版本
lsb_release -a
# 更新系统
apt update && apt upgrade -y
# 检查必要工具
which ufw || apt install ufw -y
which sudo || apt install sudo -y
which fail2ban-client || apt install fail2ban -y
```
**Ubuntu 版本与 SSH 配置方式：**
| Ubuntu 版本 | SSH 配置方式 |
|-------------|-------------|
| 22.10, 23.04, 23.10 | socket 激活，需配置 `/etc/systemd/system/ssh.socket.d/` |
| 24.04+ | 直接修改 `/etc/ssh/sshd_config` 或 `sshd_config.d/` |
### Phase 2: 创建 Sudo 用户（第一招）
```bash
# 创建用户
useradd -m -G sudo -s /bin/bash ${NEW_USER}
# 设置密码
echo "${NEW_USER}:${NEW_USER_PASSWORD}" | chpasswd
# 验证用户创建成功
id ${NEW_USER}
```
### Phase 3: 配置 SSH 安全设置（第二招）
**方式A：Ubuntu 24.04+ / 传统方式**
创建专用配置文件 `/etc/ssh/sshd_config.d/99-hardening.conf`：
```ssh
# VPS Security Hardening - generated by vps-security-hardening skill
# Author: github.com/wlzh
# Version: 1.0.0
Port ${SSH_PORT}
PermitRootLogin prohibit-password
PasswordAuthentication yes
PubkeyAuthentication yes
MaxAuthTries 3
ClientAliveInterval 300
ClientAliveCountMax 2
```
**方式B：Ubuntu 22.10/23.04/23.10（socket 激活）**
```bash
# 创建 socket 覆盖配置
mkdir -p /etc/systemd/system/ssh.socket.d
cat > /etc/systemd/system/ssh.socket.d/listen.conf << EOF
[Socket]
ListenStream=
ListenStream=${SSH_PORT}
EOF
# 禁用 socket 激活，改用传统服务
systemctl disable --now ssh.socket
systemctl enable --now ssh.service
```
**配置说明：**
- `Port`: 自定义 SSH 端口，避开默认 22
- `PermitRootLogin prohibit-password`: root 仅允许密钥登录（比 without-password 更严格）
- `PasswordAuthentication yes`: 普通用户允许密码登录（配置密钥后可改为 no）
- `PubkeyAuthentication yes`: 启用密钥认证
- `MaxAuthTries 3`: 最多尝试 3 次认证
- `ClientAliveInterval/CountMax`: 5 分钟无活动断开
### Phase 4: 配置 Fail2ban（第三招）
```bash
# 安装 fail2ban
apt install fail2ban -y
# 创建自定义配置
cat > /etc/fail2ban/jail.local << 'EOF'
[sshd]
ignoreip = 127.0.0.1/8
enabled = true
filter = sshd
port = ${SSH_PORT}
maxretry = 5
findtime = 300
bantime = 600
logpath = /var/log/auth.log
action = %(action_)s
EOF
# 启动服务
systemctl enable fail2ban
systemctl start fail2ban
```
**配置说明：**
- `ignoreip`: 白名单 IP，不会被封
- `maxretry`: 允许失败 5 次
- `findtime`: 5 分钟内
- `bantime`: 封禁 10 分钟（设为 -1 永久封禁，但不推荐）
### Phase 5: 验证 SSH 配置
```bash
# 检查配置语法
sshd -t
# 验证配置生效（重启前）
sshd -T | grep -iE "^(port|permitrootlogin|passwordauthentication|pubkeyauthentication) "
# 预期输出：
# port ${SSH_PORT}
# permitrootlogin prohibit-password
# passwordauthentication yes
# pubkeyauthentication yes
```
### Phase 6: 配置 UFW 防火墙（第六招）
```bash
# 设置默认策略
ufw default deny incoming
ufw default allow outgoing
# 允许新 SSH 端口（必须在启用前配置！）
ufw allow ${SSH_PORT}/tcp comment 'SSH custom port'
# 如果有网站服务
# ufw allow 80/tcp
# ufw allow 443/tcp
# 启用防火墙
ufw --force enable
# 删除默认 22 端口（确认新端口可用后）
ufw delete allow 22/tcp 2>/dev/null || ufw status numbered
# 查看状态
ufw status verbose
```
### Phase 7: 重启服务
```bash
# 重载配置
systemctl daemon-reload
systemctl restart ssh.service
systemctl restart fail2ban
# 验证服务状态
systemctl is-active ssh.service
systemctl is-active fail2ban
```
### Phase 8: SSH 登录通知（第五招，可选）
如需配置登录通知（企业微信/Telegram/钉钉）：
```bash
# 编辑 PAM 配置
vim /etc/pam.d/sshd
# 添加：session optional pam_exec.so /usr/local/bin/notify_ssh_login.sh
# 创建通知脚本
vim /usr/local/bin/notify_ssh_login.sh
chmod +x /usr/local/bin/notify_ssh_login.sh
```
**企业微信通知脚本示例：**
```bash
#!/bin/bash
if [ "$PAM_TYPE" != "open_session" ]; then
exit 0
fi
ip=$PAM_RHOST
date=$(date +"%e %b %Y, %a %r")
name=$PAM_USER
webhook_url="https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=你的webhook密钥"
curl -s -X POST "$webhook_url" \
-H "Content-Type: application/json" \
-d "{
\"msgtype\": \"markdown\",
\"markdown\": {
\"content\": \"**SSH登录提醒**\n> 登录用户: $name\n> 客户端IP: $ip\n> 登录时间: $date\"
}
}"
```
### Phase 9: 生成报告
执行完成后，生成包含以下内容的报告：
```
════════════════════════════════════════════════════════════

⚠️ 重要提醒:
1. 请确保 VPS 平台防火墙已开放端口 ${SSH_PORT}
2. 建议配置 SSH 密钥登录后禁用密码认证
3. 保存好新用户密码: ${NEW_USER_PASSWORD}
4. 如使用 Docker，注意配置端口映射安全（见第七招）
════════════════════════════════════════════════════════════
```
## 执行脚本
完整的自动化脚本见 `scripts/harden-vps.sh`，支持以下参数：
```bash
./scripts/harden-vps.sh \
--ip <VPS_IP> \
--root-pass <ROOT_PASSWORD> \
--user <NEW_USER> \
--user-pass <NEW_USER_PASSWORD> \
--port <SSH_PORT>
```
## Docker 安全提醒（第七招）
如果 VPS 上运行 Docker，需要注意：
1. **内部服务不暴露端口** - 数据库、Redis 等只在容器内部通信
```yaml
services:
redis:
image: redis:alpine
# 不需要 ports 配置！
```
2. **需要反代的服务只监听 127.0.0.1**
```yaml
services:
app:
ports:
- "127.0.0.1:3000:3000" # 只在本地监听
```
3. **需要公网访问的服务才暴露端口**
```yaml
services:
web:
ports:
- "80:80"
- "443:443"
```
**原因**：Docker 会直接修改 iptables 规则，绕过 UFW！
## 常见问题
