K8s搭建redis集群
示例redis1：将每个redis.yaml 的路径以及名称进行更改，如果不暴露端口可以将 type: NodePort 改为 ClusterIP，去掉nodePort: 32255，内部端口想修改可以将redis-2改为7001以此类推 vi redis-1.yaml kind: Service apiVersion: v1 metadata: name: redis-1 namespace: default labels: app: redis-1 spec: type: NodePort selector: app: redis-1 ports: - port: 6379 name: rest targetPort: 6379 protocol: TCP nodePort: 32255 --- apiVersion: apps/v1 kind: Deployment metadata: name: redis-1 namespace: default spec: replicas: 1 minReadySeconds: 120 strategy: type: RollingUpdate rollingUpdate: maxSurge: 1 maxUnavailable: 1 selector: matchLabels: app: redis-1 template: metadata: labels: app: redis-1 spec: containers: - name: redis-1 image: redis:latest imagePullPolicy: Always command: - "redis-server" args: - "/etc/redis/redis.conf" resources: limits: cpu: 1024m memory: 1024Mi requests: cpu: 50m memory: 500Mi ports: - containerPort: 6379 name: rest protocol: TCP volumeMounts: - mountPath: /var/lib/redis name: data - mountPath: /etc/redis/redis.conf name: conf securityContext: privileged: true dnsPolicy: ClusterFirst nodeName: 主机名或ip volumes: - hostPath: path: /srv/redis/test/data name: data - hostPath: path: /srv/redis/test/redis.conf name: conf kubectl apply -f redis-1.yaml 示例redis2：创建4个或6个自行决定将每个redis.yaml 的路径以及名称进行更改 vi redis-2.yaml kind: Service apiVersion: v1 metadata: name: redis-2 namespace: default labels: app: redis-2 spec: type: NodePort selector: app: redis-2 ports: - port: 6379 name: rest targetPort: 6379 protocol: TCP nodePort: 32266 --- apiVersion: apps/v1 kind: Deployment metadata: name: redis-2 namespace: default spec: replicas: 1 minReadySeconds: 120 strategy: type: RollingUpdate rollingUpdate: maxSurge: 1 maxUnavailable: 1 selector: matchLabels: app: redis-2 template: metadata: labels: app: redis-2 spec: containers: - name: redis-2 image: redis:latest imagePullPolicy: Never command: - "redis-server" args: - "/etc/redis/redis.conf" resources: limits: cpu: 1024m memory: 1024Mi requests: cpu: 50m memory: 500Mi ports: - containerPort: 6379 name: rest protocol: TCP volumeMounts: - mountPath: /var/lib/redis name: data - mountPath: /etc/redis/redis.conf name: conf securityContext: privileged: true dnsPolicy: ClusterFirst nodeName: 主机名或ip volumes: - hostPath: path: /srv/redis/test/data2 name: data - hostPath: path: /srv/redis/test/redis.conf name: conf kubectl apply -f redis-2.yaml node 节点操作 vi /srv/redis/test/redis.conf bind 0.0.0.0 masterauth 123456 requirepass 123456 slowlog-log-slower-than 100000 appendonly yes cluster-enabled yes cluster-config-file /var/lib/redis/nodes.conf cluster-node-timeout 5000 dir /var/lib/redis port 6379 node节点进行操作（本人是在单台node操作，如果有多个节点可以在多个节点进行创建，reids.conf也需要在多个节点进行创建）先创建data1-data6 mkdir -p /srv/redis/test/data{1..6} 主节点操作，查看redis 容器ip kubectl get pods -o wide | grep redis 启动好reids后进入容器后执行组建集群 redis-cli --cluster create --cluster-replicas 1 -a "密码" 192.168.68.117:7000 192.168.94.253:7001 192.168.70.33:7002 192.168.68.117:7003 192.168.94.253:7004 192.168.70.33:7005 查看集群信息在任意一个 redis 节点的主机上执行以下命令： # redis-cli -c -a "12345" -h 192.168.190.133 -p 7002 cluster info # redis-cli -c -a "12345" -h 192.168.190.133 -p 7002 cluster nodes
