# 2 部署redis #

## 2.1 准备ConfigMap ##

> 通过ConfigMap管理redis.conf文件

[root@uat-master standalone]# cat redis.conf 
    appendonly yes
    cluster-enabled no
    #cluster-config-file /var/lib/redis/nodes.conf
    #cluster-node-timeout 5000
    dir /var/lib/redis
    port 6379
    [root@uat-master standalone]# 
    [root@uat-master standalone]# kubectl create configmap redis-alone-conf -n middleware --from-file=redis.conf
    [root@uat-master standalone]# kubectl get cm -n middleware |grep redis-alone-
    redis-alone-conf   1      76m
    [root@uat-master standalone]#

## 2.1 准备pvc ##

> 创建、查看PVC

[root@uat-master standalone]# kubectl create -f pvc.yaml
    [root@uat-master standalone]# kubectl get pvc -n middleware |grep redis-alone-data

## 2.2 部署redis ##

> 创建redis Deployment

[root@uat-master standalone]# kubectl create -f redis-alone-deployment.yaml
    ······
    [root@uat-master standalone]# kubectl get pods -n middleware |grep redis
    redis-5b6ddfcd68-x22tq                    1/1     Running   0          70m
    [root@uat-master standalone]#

## 2.3 部署service ##

> 为便于远程访问，这里以NodePort方式部署service

[root@uat-master standalone]# cat redis-alone-service.yaml 
    apiVersion: v1
    kind: Service
    metadata:
      name: redis-alone-access
      namespace: middleware

        app: redis
    spec:
      selector:
        app: redis
        appCluster: redis-alone
      ports:
      - name: redis-access
        protocol: TCP
        port: 6379
        targetPort: 6379
      type: NodePort
    [root@uat-master standalone]#

> 创建、查看service

[root@uat-master standalone]# kubectl apply -f redis-alone-service.yaml 
    service/redis-alone-access unchanged
    [root@uat-master standalone]# kubectl get svc -n middleware |grep redis-alone-access
    redis-alone-access   NodePort    10.43.113.220   <none>        6379:31600/TCP                  69m

# 3 远程访问redis #

> **先要确保k8s集群主机31600端口能够远程访问**
