负载均衡器设置

概述

部署和配置负载均衡器，将流量分发到多个后端服务器，确保基础设施的高可用性、容错能力和最优资源利用率。

使用场景

多服务器流量分发
高可用性和故障转移
会话持久化和粘性会话
健康检查和自动恢复
SSL/TLS 终止
跨区域负载均衡
在负载均衡器层面进行 API 速率限制
DDoS 缓解

快速开始

最小工作示例：

# /etc/haproxy/haproxy.cfg
global
    log stdout local0
    log stdout local1 notice
    maxconn 4096
    daemon

    # Security
    tune.ssl.default-dh-param 2048
    ssl-default-bind-ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256
    ssl-default-bind-options ssl-min-ver TLSv1.2

defaults
    log global
    mode http
    option httplog
    option denylogin
    option forwardfor
    option http-server-close

    # Timeouts
    timeout connect 5000
    timeout client 50000
    timeout server 50000

Load Balancer Setup

Overview

Quick Start
Reference Guides
Best Practices

Overview

Deploy and configure load balancers to distribute traffic across multiple backend servers, ensuring high availability, fault tolerance, and optimal resource utilization across your infrastructure.

When to Use

Multi-server traffic distribution
High availability and failover
Session persistence and sticky sessions
Health checking and auto-recovery
SSL/TLS termination
Cross-region load balancing
API rate limiting at load balancer
DDoS mitigation

Quick Start

Minimal working example:

# /etc/haproxy/haproxy.cfg
global
    log stdout local0
    log stdout local1 notice
    maxconn 4096
    daemon

    # Security
    tune.ssl.default-dh-param 2048
    ssl-default-bind-ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256
    ssl-default-bind-options ssl-min-ver TLSv1.2

defaults
    log global
    mode http
    option httplog
    option denylogin
    option forwardfor
    option http-server-close

    # Timeouts
    timeout connect 5000
    timeout client 50000
    timeout server 50000

Best Practices

✅ DO

Implement health checks
Use connection pooling
Enable session persistence when needed
Monitor load balancer metrics
Implement rate limiting
Use multiple availability zones
Enable SSL/TLS termination
Implement graceful connection draining

❌ DON'T

Allow single point of failure
Skip health check configuration
Mix HTTP and HTTPS without redirect
Ignore backend server limits
Over-provision without monitoring
Cache sensitive responses
Use default security groups
Neglect backup load balancers
