游戏服务器部署双十二活动

# 示例代码：使用Nginx配置负载均衡
upstream backend {
    server 192.168.1.1:8000;
    server 192.168.1.2:8000;
    server 192.168.1.3:8000;
}

server {
    listen 80;
    location / {
        proxy_pass http://backend;
    }
}

# 示例代码：使用Redis缓存
import redis

r = redis.Redis(host='localhost', port=6379, db=0)

def get_data(key):
    data = r.get(key)
    if data is None:
        data = fetch_from_database(key)
        r.setex(key, 3600, data)  # 缓存1小时
    return data

# 示例代码：Kubernetes自动扩展配置

# 示例代码：使用分布式锁保证数据一致性
from redis import StrictRedis
from redis_lock import Lock

r = StrictRedis()

def update_data(key, value):
    with Lock(r, key + '_lock'):
        # 执行数据更新操作
        r.set(key, value)
