k8s 搭建redis集群

环境

master01  172.16.248.191
node01     172.16.248.171
node02     172.16.248.173

目录

1.创建NFS存储

2、创建PV

3、创建Configmap

4、创建Headless service

         5、创建Redis 集群节点

         6、初始化集群

         7、创建Service

1.创建NFS存储

（node02）安装NFS

yum -y install nfs-utils rpcbind

新建文件/etc/exports

/usr/local/k8s/redis/pv1 *(rw,all_squash)
/usr/local/k8s/redis/pv2 *(rw,all_squash)
/usr/local/k8s/redis/pv3 *(rw,all_squash)
/usr/local/k8s/redis/pv4 *(rw,all_squash)
/usr/local/k8s/redis/pv5 *(rw,all_squash)
/usr/local/k8s/redis/pv6 *(rw,all_squash)

创建相应目录

mkdir -p /usr/local/k8s/redis/pv{1..6}

给目录赋权限

chmod 777 /usr/local/k8s/redis/pv*

启动NFS和rpcbind服务

systemctl start rpcbind
systemctl start nfs

安装nfs服务不然启动pod会报错

yum -y install nfs-utils rpcbind

2、创建PV

master01

创建pv.yml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: nfs-pv1
spec:
  capacity:
    storage: 200M
  accessModes:
    - ReadWriteMany
  nfs:
    server: 172.16.248.173
    path: "/usr/local/k8s/redis/pv1"

---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: nfs-pv2

  nfs:
    server: 172.16.248.173
    path: "/usr/local/k8s/redis/pv2"
