1、配置helm redis repo
helm repo add bitnami https://charts.bitnami.com/bitnami2 安装下载helm redis
下面是默认安装，不过前往别直接拿着下面安装命令就安装，官方默认安装的默认参数配置往往和我们实际场景不一样，需要配置一些参数
helm install my-redis bitnami/redis --version 18.7.02.1 下载helm redis
helm pull bitnami/redis --version 18.7.02.2 查看storageclass
如果环境中没有storageclass，就需自己安装存储支持或者采用云厂商的storageclass，内网环境推荐openebs，测试nfs就行了。
我的默认storageclass是openebs-hostpath，我的k8s环境上安装的openebs来做存储支持。当然如果有其他支持storageclass的也可以，比如nfs、云厂商sc，这里不做过多解释。
[root@k8s-master01 redis]# kubectl get storageclass
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
openebs-device openebs.io/local Delete WaitForFirstConsumer false 20d
openebs-hostpath (default) openebs.io/local Delete WaitForFirstConsumer false 20d2.3 通过指定my-values.yaml安装
不过在这里因为是安装单机版，并且需要配置一些参数，所以需要通过--values配置一些参数
global:storageClass: "openebs-hostpath"redis:password: "redis123"architecture: standalonecommonConfiguration: |-appendonly yessave "300 10"master:resources:limits: cpu: 2memory: 4Girequests: cpu: 500mmemory: 2GinodeSelector: {}tolerations: []persistence:size: 10Giservice:type: NodePortnodePorts:redis: "30202"- storageClass可以不用配置，因为我的默认storageClass已经配置。
- password 配置密码
- architecture 配置单机部署
- commonConfiguration 配置redis的存储策略
- master 主redis相关配置
安装前测试：
helm -n newland install redis -f my-values.yaml ./redis --dry-run安装：
helm -n newland install redis -f my-values.yaml ./redis2.4 直接修改values.yaml
我用的比较多的是直接修改values.yaml，修改的参数和上面的一样，找到对应的位置修改
安装测试：
[root@k8s-master01 redis]# helm install redis -n newland ../redis --dry-run安装：
[root@k8s-master01 redis]# helm install redis -n newland ../redis2.5 查看安装情况
helm查看安装：

127.0.0.1:6379> get a
(nil)通过测试可以看出安装成功了，我们本地需要连接redis直接使用nodeport端口30379，如果是k8s内直接使用service:6379就行了
