PHP实现CMDB系统

CMDB（配置管理数据库）用于集中管理IT基础设施的配置项信息。以下是基于PHP实现CMDB系统的关键要点：

数据库设计

创建核心表结构存储配置项信息：

CREATE TABLE ci (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255) NOT NULL,
    type_id INT NOT NULL,
    status TINYINT DEFAULT 1,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE ci_types (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100) NOT NULL,
    description TEXT
);

CREATE TABLE ci_attributes (
    ci_id INT NOT NULL,
    attr_name VARCHAR(100) NOT NULL,
    attr_value TEXT,
    PRIMARY KEY (ci_id, attr_name)
);

核心功能实现

配置项管理类示例：

class ConfigurationItem {
    private $db;

    public function __construct($dbConnection) {
        $this->db = $dbConnection;
    }

    public function addCI($name, $typeId, $attributes = []) {
        $stmt = $this->db->prepare("INSERT INTO ci (name, type_id) VALUES (?, ?)");
        $stmt->execute([$name, $typeId]);
        $ciId = $this->db->lastInsertId();

        foreach($attributes as $name => $value) {
            $this->addAttribute($ciId, $name, $value);
        }

        return $ciId;
    }

    private function addAttribute($ciId, $name, $value) {
        $stmt = $this->db->prepare("INSERT INTO ci_attributes VALUES (?, ?, ?)");
        $stmt->execute([$ciId, $name, $value]);
    }
}

关系建模

实现配置项之间的关系管理：

class CIRelationship {
    private $db;

    public function __construct($dbConnection) {
        $this->db = $dbConnection;
    }

    public function addRelationship($sourceId, $targetId, $relationType) {
        $stmt = $this->db->prepare("INSERT INTO ci_relationships VALUES (?, ?, ?)");
        return $stmt->execute([$sourceId, $targetId, $relationType]);
    }
}

前端界面

使用Bootstrap构建管理界面：

<div class="ci-form">
    <form method="post" action="save_ci.php">
        <div class="form-group">
            <label>CI名称</label>
            <input type="text" name="name" class="form-control" required>
        </div>

        <div class="form-group">
            <label>CI类型</label>
            <select name="type_id" class="form-control">
                <?php foreach($ciTypes as $type): ?>
                <option value="<?= $type['id'] ?>"><?= htmlspecialchars($type['name']) ?></option>
                <?php endforeach ?>
            </select>
        </div>
    </form>
</div>

扩展功能

实现自动发现功能示例：

class AutoDiscovery {
    public function scanNetwork($subnet) {
        // 实现网络扫描逻辑
        $devices = [];
        // ...
        return $devices;
    }

    public function importToCMDB($discoveredDevices) {
        foreach($discoveredDevices as $device) {
            $this->ciModel->addCI($device['name'], $device['type'], $device['attrs']);
        }
    }
}

安全考虑

实现基本的访问控制：

php实现cmdb

class AccessControl {
    public function checkPermission($userId, $action) {
        $stmt = $this->db->prepare("SELECT COUNT(*) FROM user_permissions WHERE user_id = ? AND permission = ?");
        $stmt->execute([$userId, $action]);
        return $stmt->fetchColumn() > 0;
    }
}

以上代码示例展示了PHP实现CMDB系统的核心组件，实际开发中需要根据具体需求进行扩展和完善。建议采用MVC架构组织代码，并使用Composer管理依赖。
