1.创建NFS存储

安装NFS

yum install nfs-utils -y

准备一个共享目录

mkdir /opt/nfs/data/{pv1,pv2,pv3} -pv

将共享目录以读写权限暴露给192.168.60.0/24网段中的所有主机

cat > /etc/exports << EOF
/opt/nfs/data/pv1 192.168.60.0/24(rw,sync,no_root_squash)
/opt/nfs/data/pv2 192.168.60.0/24(rw,sync,no_root_squash)
/opt/nfs/data/pv3 192.168.60.0/24(rw,sync,no_root_squash)

EOF

启动nfs服务

systemctl start nfs

2.创建PV PVC存储

pv.yaml 如下：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv1
  namespace: dev
spec:
  capacity:
    storage: 1Gi
  accessModes:
  - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: redis-nfs1
  nfs:
    path: /opt/nfs/data/pv1
    server: 192.168.60.128


---


apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv2
  namespace: dev
spec:
  capacity:
    storage: 1Gi
  accessModes:
  - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: redis-nfs2
  nfs:
    path: /opt/nfs/data/pv2
    server: 192.168.60.128
    
---


apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv3
  namespace: dev
spec:
  capacity:
    storage: 1Gi
  accessModes:
  - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: redis-nfs3
  nfs:
    path: /opt/nfs/data/pv3
    server: 192.168.60.128
    
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: redis-pvc1
  namespace: dev
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  storageClassName: redis-nfs1

1.使用命令创建pv pvc

kubectl create -f pv.yaml

2.使用命令查看pv和pvc绑定情况

kubectl get pv,pvc -n dev

3.创建ConfigMap

redis-configMap.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: redis
  namespace: dev
data:
  redis.conf: |+
    requirepass 123456
    protected-mode no
    port 6379
    tcp-backlog 511
    timeout 0
    tcp-keepalive 300
    daemonize no
    supervised no
    pidfile /var/run/redis_6379.pid
    loglevel notice
    logfile ""
    databases 16
    always-show-logo yes
    save 900 1
    save 300 10
    save 60 10000
    stop-writes-on-bgsave-error yes
    rdbcompression yes
    rdbchecksum yes
    dbfilename dump.rdb
    dir /data
    slave-serve-stale-data yes
    slave-read-only yes
    repl-diskless-sync no
    repl-diskless-sync-delay 5
    repl-disable-tcp-nodelay no
    slave-priority 100
    lazyfree-lazy-eviction no
    lazyfree-lazy-expire no
    lazyfree-lazy-server-del no
    slave-lazy-flush no
    appendonly yes
    appendfilename "appendonly.aof"
    appendfsync everysec
    no-appendfsync-on-rewrite no
    auto-aof-rewrite-percentage 100
    auto-aof-rewrite-min-size 64mb
    aof-load-truncated yes
    aof-use-rdb-preamble no
    lua-time-limit 5000
    slowlog-log-slower-than 10000
    slowlog-max-len 128
    latency-monitor-threshold 0
    notify-keyspace-events Ex
    hash-max-ziplist-entries 512
    hash-max-ziplist-value 64
    list-max-ziplist-size -2
    list-compress-depth 0
    set-max-intset-entries 512
    zset-max-ziplist-entries 128

    hz 10
    aof-rewrite-incremental-fsync yes

使用命令：

kubectl apply -f redis-configMap.yaml

4.Redis Deploy 创建

redis-deploy.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis
  namespace: dev
  labels:
    app: redis
spec:
  strategy:
    type: Recreate
  selector:
    matchLabels:
      app: redis
  template:
    metadata:
      labels:
        app: redis
    spec:
      containers:
      - name: redis
        image: redis
        imagePullPolicy: IfNotPresent
        command: ["redis-server","/etc/redis/redis.conf"]
        ports:
        - containerPort: 6379
        volumeMounts:
        - name: redis-config
          mountPath: /etc/redis/redis.conf
          subPath: redis.conf
        - name: redis-persistent-storage
          mountPath: /data
      volumes:
      - name: redis-config
        configMap:
          name: redis
          items:
          - key: redis.conf
            path: redis.conf
      - name: redis-persistent-storage
        persistentVolumeClaim:
          claimName: redis-pvc1
          
---
kind: Service
apiVersion: v1
metadata:
  name: redis
  namespace: dev
spec:
  type: NodePort
  selector:
    app: redis
  ports:
  - port: 6379
    targetPort: 6379
