性能优化策略

数据库优化

-- PostgreSQL性能优化配置
ALTER DATABASE headscale_prod SET work_mem = '16MB';
ALTER DATABASE headscale_prod SET maintenance_work_mem = '256MB';
ALTER DATABASE headscale_prod SET random_page_cost = 1.1;
ALTER DATABASE headscale_prod SET effective_cache_size = '4GB';

-- 关键表索引优化
CREATE INDEX idx_nodes_updated_at ON nodes(updated_at);
CREATE INDEX idx_users_created_at ON users(created_at);
CREATE INDEX idx_api_keys_expires_at ON api_keys(expires_at);
CREATE INDEX idx_preauth_keys_expiration ON preauth_keys(expiration);

内存缓存配置

caching:
  enabled: true
  # 节点信息缓存
  node_cache:
    ttl: 5m
    max_size: 10000
  # 用户信息缓存  
  user_cache:
    ttl: 10m
    max_size: 1000
  # ACL策略缓存
  policy_cache:
    ttl: 1m
    max_size: 100
  # 中继映射缓存
  relay_cache:
    ttl: 30m
    max_size: 50

故障排除与恢复

常见问题处理指南

问题现象	可能原因	解决方案
节点无法连接	中继服务器不可达	检查中继服务器状态和网络连通性
ACL策略不生效	策略文件语法错误	使用headscale configtest验证配置
数据库连接失败	连接数过多或认证失败	检查数据库连接池配置和凭据
性能下降	内存或CPU资源不足	调整资源限制和缓存配置
证书错误	TLS证书过期或配置错误	更新证书并验证配置路径

灾难恢复流程
