黑马2025 AI运维云计算课详解：AI赋能+云计算部署+故障预测实战指南
一、AI赋能运维核心架构
1. 智能监控系统实现
Python
import pandas as pd
from sklearn.ensemble import IsolationForest
from prometheus_client import start_http_server, Gauge
# 异常检测模型
class AnomalyDetector:
def __init__(self):
self.model = IsolationForest(n_estimators=100, contamination=0.01)
def train(self, historical_data):
"""使用历史数据训练模型"""
self.model.fit(historical_data[['cpu', 'memory', 'disk']])
def predict(self, metrics):
"""实时预测异常"""
return self.model.predict([[metrics['cpu'], metrics['memory'], metrics['disk']]])
# Prometheus监控集成
cpu_usage = Gauge('cpu_usage', 'Current CPU usage percentage')
anomaly_score = Gauge('anomaly_score', 'Anomaly detection score')
def monitor_loop():
detector = AnomalyDetector()
detector.train(pd.read_csv('historical_metrics.csv'))
while True:
current_metrics = get_system_metrics() # 获取当前指标
prediction = detector.predict(current_metrics)
# 上报指标
cpu_usage.set(current_metrics['cpu'])
anomaly_score.set(prediction[0])
if prediction[0] == -1: # 异常检测
alert_ops_team(current_metrics)
if __name__ == '__main__':
start_http_server(8000) # 启动Prometheus指标暴露
monitor_loop()
二、云原生部署实战
1. Kubernetes智能调度器
Python
from kubernetes import client, config
from sklearn.cluster import KMeans
import numpy as np
# 加载K8s配置
config.load_kube_config()
v1 = client.CoreV1Api()
class AIScheduler:
def __init__(self):
self.model = KMeans(n_clusters=3)
def analyze_node_metrics(self):
"""收集节点指标并聚类"""
nodes = v1.list_node().items
metrics = []
for node in nodes:
cpu = node.status.capacity['cpu']
memory = node.status.capacity['memory']
metrics.append([cpu, memory])
self.model.fit(np.array(metrics))
return self.model.labels_
def schedule_pod(self, pod_spec):
"""智能调度Pod"""
node_labels = self.analyze_node_metrics()
best_node = self.select_optimal_node(pod_spec, node_labels)
# 创建绑定
binding = client.V1Binding(
target=client.V1ObjectReference(
kind="Node",
name=best_node
)
)
v1.create_namespaced_pod_binding(
name=pod_spec.metadata.name,
namespace=pod_spec.metadata.namespace,
body=binding
)
# 使用示例
scheduler = AIScheduler()
pod = client.V1Pod(metadata=client.V1ObjectMeta(name="ai-app"))
scheduler.schedule_pod(pod)
三、故障预测系统
1. LSTM故障预测模型
Python
import tensorflow as tf
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import LSTM, Dense
from sklearn.preprocessing import MinMaxScaler
# 准备时序数据
def prepare_data(data, n_steps=10):
scaler = MinMaxScaler()
scaled = scaler.fit_transform(data)
X, y = [], []
for i in range(len(scaled)-n_steps):
X.append(scaled[i:i+n_steps])
y.append(scaled[i+n_steps])
return np.array(X), np.array(y)
# 构建LSTM模型
def build_model(n_steps, n_features):
model = Sequential([
LSTM(50, activation='relu', input_shape=(n_steps, n_features)),
Dense(n_features)
])
model.compile(optimizer='adam', loss='mse')
return model
# 训练预测模型
historical_data = pd.read_csv('system_logs.csv')[['cpu', 'memory', 'disk']]
X, y = prepare_data(historical_data.values)
model = build_model(X.shape[1], X.shape[2])
model.fit(X, y, epochs=20, verbose=1)
# 预测未来状态
def predict_failure(window_data):
scaler = MinMaxScaler()
scaled_window = scaler.fit_transform(window_data)
prediction = model.predict(np.array([scaled_window]))
return scaler.inverse_transform(prediction)

五、智能运维平台核心代码
1. 自动化故障处理
Python
import requests
from datetime import datetime
class AutoHealer:
def __init__(self):
self.incident_db = IncidentDatabase()
self.solution_db = SolutionKnowledgeBase()
def handle_alert(self, alert):
# 相似事件检索
similar_incidents = self.incident_db.search(
metrics=alert['metrics'],
timestamp=alert['timestamp']
)
if similar_incidents:
# 应用已知解决方案
solution = self.solution_db.get(similar_incidents[0]['id'])
self.execute_playbook(solution['playbook'])
else:
# 启动诊断流程
root_cause = self.diagnose(alert)
new_solution = self.generate_solution(root_cause)
self.solution_db.add(new_solution)
self.execute_playbook(new_solution['playbook'])
def diagnose(self, alert):
# 使用知识图谱+机器学习诊断
diagnostic_data = {
'metrics': alert['metrics'],
'log_patterns': self.analyze_logs(alert['host']),
'dependency_graph': self.get_dependencies(alert['service'])
}
return self.predict_root_cause(diagnostic_data)
def execute_playbook(self, playbook):
for step in playbook['steps']:
if step['type'] == 'k8s':
self.k8s_operation(step['command'])
elif step['type'] == 'shell':
self.run_shell(step['command'])
# 使用示例
healer = AutoHealer()
healer.handle_alert({
'host': 'node-1',
'service': 'payment-service',
'metrics': {'cpu': 95, 'memory': 90},
'timestamp': datetime.now()
})
2. 云资源优化推荐
Python
import pulp
from collections import defaultdict
class ResourceOptimizer:
def __init__(self, cluster_data):
self.nodes = cluster_data['nodes']
self.pods = cluster_data['pods']
def optimize(self):
# 创建线性规划问题
prob = pulp.LpProblem("Resource_Optimization", pulp.LpMinimize)
# 决策变量：Pod是否部署到Node (0或1)
x = pulp.LpVariable.dicts(
"x",
((p, n) for p in self.pods for n in self.nodes),
cat='Binary'
)
# 目标函数：最小化资源碎片
prob += pulp.lpSum(
x[p, n] * self.calculate_fragmentation(p, n)
for p in self.pods for n in self.nodes
)
# 约束条件：每个Pod只能部署到一个Node
for p in self.pods:
prob += pulp.lpSum(x[p, n] for n in self.nodes) == 1
# 约束条件：Node资源不能超限
for n in self.nodes:
prob += pulp.lpSum(
x[p, n] * self.pods[p]['cpu'] for p in self.pods
) <= self.nodes[n]['cpu_capacity']
prob += pulp.lpSum(
x[p, n] * self.pods[p]['memory'] for p in self.pods
) <= self.nodes[n]['memory_capacity']
# 求解问题
prob.solve()
# 返回优化方案
return {
p: n for p in self.pods
for n in self.nodes
if pulp.value(x[p, n]) == 1
}
# 使用示例
optimizer = ResourceOptimizer({
'nodes': {
'node1': {'cpu_capacity': 8, 'memory_capacity': 32},
'node2': {'cpu_capacity': 16, 'memory_capacity': 64}
},
'pods': {
'podA': {'cpu': 2, 'memory': 8},
'podB': {'cpu': 4, 'memory': 16}
}
})
print(optimizer.optimize()) # 输出最优部署方案
