3.1 CNI 确认

kubectl get pods -n kube-system|grepcilium-agent

结果:

cilium-7hjkj 1/1 Running 0 9d cilium-fk6px 1/1 Running 0 9d cilium-gsn82 1/1 Running 1 (5d ago) 9d cilium-mgjrg 1/1 Running 0 9d

结果: (无输出)集群中无 kube-proxy

3.2 Cilium kube-proxy 替代模式

kubectl get cm -n kube-system cilium-config -ojsonpath='{.data.kube-proxy-replacement}'

结果:

strict # Cilium 完全替代 kube-proxy

3.3 Cilium BPF LB 配置

kubectl get cm -n kube-system cilium-config -ojsonpath='{.data.bpf-lb-sock}'

结果:

false # 使用标准 eBPF LB (非 socket level)

3.4 Cilium Service 负载均衡详情

kubectlexec-n kube-system cilium-7hjkj -- ciliumservicelist|grep-A5"246.99.91.187"

ID Frontend Service Type Backend 134 246.99.91.187:6379 ClusterIP 1 => 245.0.2.240:7617 (active) 2 => 245.0.1.147:7617 (active)

3.5 BPF Maps

kubectlexec-n kube-system cilium-7hjkj -- bpftool map list|grep-E"cilium.*lb"

结果:

929: lru_hash name cilium_lb4_reve flags 0x0 930: hash name cilium_lb4_serv flags 0x1 # Service 映射表 931: hash name cilium_lb4_back flags 0x1 # Backend 映射表 932: hash name cilium_lb4_reve flags 0x1 941: hash name cilium_lb_affin flags 0x1 # 会话亲和 942: lru_hash name cilium_lb4_affi flags 0x0 943: lpm_trie name cilium_lb4_sour flags 0x1

3.6 流量策略配置

kubectl get svc -n qfusion-admin redis-2305e2850 -o yaml|grep-E"sessionAffinity|internalTrafficPolicy"

结果:

internalTrafficPolicy: Cluster # 集群内流量可路由到所有节点 sessionAffinity: None # 无会话亲和

3.7 负载均衡总结

四、Predixy 后端 Redis 连接配置

4.1 Predixy ConfigMap

kubectl get configmap redis-2305e285-predixy-conf -n qfusion-admin -o yaml

cluster.conf 配置:

ClusterServerPool { Password MasterReadPriority 60 # 主节点读优先级 StaticSlaveReadPriority 50 # 静态从节点读优先级 DynamicSlaveReadPriority 50 # 动态从节点读优先级 RefreshInterval 1 # 配置刷新间隔(秒) ServerTimeout 1 # 服务器超时(秒) ServerFailureLimit 10 # 故障阈值 ServerRetryTimeout 1 # 重试超时(秒) KeepAlive 120 # 连接保活(秒) Servers { + redis-2305e285.qfusion-admin:6379 } }

读写策略:

• 写操作: 发往 Master
• 读操作: 优先 Master (60)，其次 Slave (50)

4.2 后端 Redis Server Pods 分布

kubectl get pods -n qfusion-admin -l redis.resource.type=server -o wide|grepredis-2305e285

结果:

NAME READY STATUS RESTARTS AGE IP NODE drc-redis-2305e285-0-0 3/3 Running 0 2d17h 245.0.1.48 qfusion2 drc-redis-2305e285-0-1 3/3 Running 0 2d17h 245.0.3.84 qfusion4 drc-redis-2305e285-1-0 3/3 Running 0 2d17h 245.0.0.107 qfusion1 drc-redis-2305e285-1-1 3/3 Running 0 2d17h 245.0.2.168 qfusion3 drc-redis-2305e285-2-0 3/3 Running 0 2d17h 245.0.2.214 qfusion3 drc-redis-2305e285-2-1 3/3 Running 0 2d17h 245.0.3.200 qfusion4

4.3 Redis 主从角色分布

kubectl get QfrCluster redis-2305e285 -n qfusion-admin -ojsonpath='{.metadata.annotations}'

结果:

drc-redis-2305e285-0-0/info.role: slave drc-redis-2305e285-0-1/info.role: master drc-redis-2305e285-1-0/info.role: slave drc-redis-2305e285-1-1/info.role: master drc-redis-2305e285-2-0/info.role: slave drc-redis-2305e285-2-1/info.role: master

架构: 3 分片，每分片 1主1从

4.4 Redis Service Endpoints

kubectl get endpoints redis-2305e285 -n qfusion-admin

结果:

NAME ENDPOINTS AGE redis-2305e285 245.0.0.107:6379,245.0.1.48:6379,245.0.2.168:6379 + 15 more...

五、高可用机制

5.1 Predixy 健康检查

kubectl get pod redis-2305e285-predixy-0 -n qfusion-admin -ojsonpath='{.spec.containers[0].livenessProbe}'

结果:

{"exec":{"command":["sh","-c","redis-cli -h $(hostname) -p 7617 ping"]},"failureThreshold":3,"initialDelaySeconds":30,"periodSeconds":10,"successThreshold":1,"timeoutSeconds":5}

kubectl get pod redis-2305e285-predixy-0 -n qfusion-admin -ojsonpath='{.spec.containers[0].readinessProbe}'

结果:

{"exec":{"command":["sh","-c","redis-cli -h $(hostname) -p 7617 ping"]},"failureThreshold":5,"initialDelaySeconds":30,"periodSeconds":15,"successThreshold":1,"timeoutSeconds":5}

健康检查策略:

5.2 Cilium 服务发现与故障转移

Cilium 通过以下机制实现高可用:

1. eBPF Map 实时更新: 当 Pod 状态变化时，Cilium 自动更新 BPF maps
2. Backend 健康监控: Cilium 监控 Backend 状态，自动剔除不健康的后端
3. 无状态转发: 内核态直接转发，无需中间代理

5.3 节点级容错

容错能力: 任一节点故障，另一个节点的 Predixy 仍可处理全部流量
