helm3 安装 redis-ha 高可用集群（过程超详细：包含k8s、nfs、storageclass安装步骤）

2022年6月9日09:08:33

一、资源准备 (所有机器上执行)

主机名	公网 IP	私网 IP
k8s-master01	39.104.173.77	172.24.114.3
k8s-node01	39.104.179.210	172.24.114.4
k8s-node02	39.104.173.12	172.24.114.1
k8s-node03	39.104.177.2	172.24.114.2

更改主机名

# 在虚拟机 172.24.114.3 上，设置 k8s-master01 节点
hostnamectl set-hostname k8s-master01bash#立马生效# 在虚拟机 172.24.114.4 上，设置 k8s-node01 节点
hostnamectl set-hostname k8s-node01bash#立马生效# 在虚拟机 172.24.114.1 上，设置 k8s-node02 节点
hostnamectl set-hostname k8s-node02bash#立马生效# 在虚拟机 172.24.114.2 上，设置 k8s-node03 节点
hostnamectl set-hostname k8s-node03bash#立马生效

关闭防火墙

systemctl stop firewalld
systemctl disable firewalld

允许 iptables 检查桥接流量

cat<<EOF|sudotee /etc/modules-load.d/k8s.conf
br_netfilter
EOFcat<<EOF|sudotee /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOFsudo sysctl --system

将 SELinux 设置为 permissive 模式（相当于将其禁用）

sudo setenforce0sudosed -i's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/config

关闭swap(k8s禁止虚拟内存提供性能)

swapoff -ased -ri's/.*swap.*/#&/' /etc/fstab#关闭swap分区

配置/etc/hosts

# 自定义master与node IP，请根据个人情况修改cat>> /etc/hosts<<EOF
172.28.12.148 master1
172.28.12.149 node1
EOF

6.1 安装docker

#清理过往版本dockersudo yum remove docker\
                  docker-client\
                  docker-client-latest\
                  docker-common\
                  docker-latest\
                  docker-latest-logrotate\
                  docker-logrotate\
                  docker-engine

#安装dockersudo yuminstall -y yum-utilssudo yum-config-manager\
    --add-repo\
    http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.reposudo yum makecache fastsudo yuminstall docker-ce docker-ce-cli containerd.io -ysudo systemctl start dockersudo systemctlenable dockersudo systemctl status docker

6.2 修改docker驱动

执行kubeadm init集群初始化时遇到：

[WARNING IsDockerSystemdCheck]: detected “cgroupfs” as the Docker
cgroup driver. The recommended driver is “systemd”.

[警告IsDockerSystemdCheck]：检测到“cgroupfs”作为Docker cgroup驱动程序。
推荐的驱动程序是“systemd”

#新增配置文件cat>> /etc/docker/daemon.json<<EOF
{
 "exec-opts":["native.cgroupdriver=systemd"]
}
EOF#重启docker
systemctl restart docker
systemctl status docker

配置阿里云kubernetes软件源
报错：[Errno -1] repomd.xml signature could not be verified for kubernetes Trying other mirror.
解决：https://github.com/kubernetes/kubernetes/issues/60134
处理：repo_gpgcheck=0

cat<<EOF> /etc/yum.repos.d/kubernetes.repo

EOF

安装kubelet kubeadm kubectl

sudo yum update -y#针对修改repo_gpgcheck=0# sudo yum install -y kubelet-1.19.4 kubeadm-1.19.4 kubectl-1.19.4 #可以根据github发布版本，指定# sudo yum install -y kubelet-1.20.0 kubeadm-1.20.0 kubectl-1.20.0 #可以根据github发布版本，指定sudo  yuminstall -y kubelet kubeadm kubectl#最好不要指定版本，默认更新为最新sudo systemctlenable --now kubeletsudo systemctl start kubelet#sudo systemctl status kubelet 此时kubelet还没有正常准备，待kubeadm init后master节点会ok，将node节点join添加后kubelet也会正常

helm3 安装 redis-ha 高可用集群（过程超详细：包含k8s、nfs、storageclass安装步骤）

检查工具安装

yum list installed|grep kubelet
yum list installed|grep kubeadm
yum list installed|grep kubectl

kubelet --version#查看集群版本结果 Kubernetes v1.23.3

二、kubeadm创建集群

kubeadm初始化集群 #在master上执行
切记修改为master的IP地址， --apiserver-advertise-address 172.24.114.3

#apiserver-advertise-address 172.28.12.148为master节点IP，根据个人master IP修改
kubeadm init --apiserver-advertise-address172.24.114.3\
--image-repository registry.aliyuncs.com/google_containers\
--pod-network-cidr10.244.0.0/16\
--service-cidr10.96.0.0/12#--kubernetes-version v1.23.3 \ #本行，可以不添加，默认使用最新的版本

此处如果执行失败，可能master的IP填写错误或者未填写 --apiserver-advertise-address
172.24.114.3

kubeadm reset

然后输入：y
已完成 kubeadm init 重置，重新执行以上命令kubeadm init …

#客户端kubectl接入集群mkdir -p$HOME/.kubesudocp -i /etc/kubernetes/admin.conf$HOME/.kube/configsudochown$(id -u):$(id -g)$HOME/.kube/config

注意：在worker节点上执行

#worker节点添加到集群 ---> 在worker节点node1上执行#自动生成，请保留
kubeadmjoin172.24.114.3:6443 --token bofh8w.5r6qwmvargj3d0do\
    --discovery-token-ca-cert-hash sha256:0724d03bf5ca008808b4dc9c68643c90e54d36733a487dc7d73`在这里插入代码片`0dca35a952b89

kubectl apply -f ./kube-flannel.yml#此处应用后node状态由NotReady --> Ready

12.控制面master1查看集群

[root@iZ0jlhvtxignmaozy30vffZ ~]# kubectl get nodes
NAME                      STATUS   ROLES    AGE     VERSION

13.工作负载worker节点(k8s-node01、k8s-node02、k8s-node03 配置admin.conf，实现worker节点 kubectl get …)

# k8s-master01 传文件到k8s-node01、k8s-node02、k8s-node03# 其中172.24.114.4为 k8s-node01 节点scp -r /etc/kubernetes/admin.conf root@172.24.114.4:/etc/kubernetes/# 其中172.24.114.1为  k8s-node02 节点scp -r /etc/kubernetes/admin.conf root@172.24.114.1:/etc/kubernetes/# 其中172.24.114.2为 k8s-node03 节点scp -r /etc/kubernetes/admin.conf root@172.24.114.2:/etc/kubernetes/# 在k8s-node01、k8s-node02、k8s-node03 执行echo"export KUBECONFIG=/etc/kubernetes/admin.conf">> ~/.bash_profilesource ~/.bash_profile

helm3 安装 redis-ha 高可用集群（过程超详细：包含k8s、nfs、storageclass安装步骤）

三、新增work节点

14、请按顺序执行0-9步骤

15、新worker节点添加到集群

#在新worker节点上
kubeadmjoin --token<token>  --discovery-token-ca-cert-hash sha256:<hash>

kubeadm token list#集群创建在24小时以内，获取<token>
或者
kubeadm token create#集群创超过24小时，获取<token>

openssl x509 -pubkey -in /etc/kubernetes/pki/ca.crt| openssl rsa -pubin -outform der2>/dev/null|\
   openssl dgst -sha256 -hex|sed's/^.* //'#获取<hash>

16、新节点配置kubectl客户端工具
请执行第13步骤

四、安装 NFS

主机名	公网 IP	私网 IP
k8s-master01	39.104.173.77	172.24.114.3
k8s-node01	39.104.179.210	172.24.114.4
k8s-node02	39.104.173.12	172.24.114.1
k8s-node03	39.104.177.2	172.24.114.2

4.0、搭建 NFS （选择 k8s-master01 172.24.114.3 ）

       server:172.24.114.3 
       path: /data/redis

4.1 在提供 NFS 存储主机上执行，这里默认k8s-master01节点

yuminstall -y nfs-utils#这条命令所有节点master、worker都执行echo"/data/harbor *(insecure,rw,sync,no_root_squash)"> /etc/exports# 执行以下命令，启动 nfs 服务;创建共享目录mkdir -p /data/redis# 在master执行chmod -R777 /data/redis# 使配置生效
exportfs -r#检查配置是否生效
exportfs

systemctlenable rpcbind&& systemctl start rpcbind

systemctlenable nfs&& systemctl start nfs

4.2 在worker主机上执行(k8s-node01 k8s-node02 k8s-node03)

yuminstall -y nfs-utils#这条命令所有节点master、worker都执行

showmount -e172.24.114.3#查看worker节点是否能查到master节点的nfs文件

五、配置 StorageClass 存储

vim redis-storage.yaml

## 创建了一个存储类
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: nfs-storage
  annotations:
    storageclass.kubernetes.io/is-default-class:"true"

              mountPath: /persistentvolumes
          env:

kubectl apply -f redis-storage.yaml

六、安装 helm

6.1 安装包的下载地址：https://github.com/helm/helm/releases
6.2 下载软件包：helm-v3.6.3-linux-amd64.tar.gz，如下二选一

七、helm 安装 redis-ha 高可用 redis 集群

7.1 查找官方helm hub chart库：

[root@k8s-master01 ~]# helm search hub redis

7.2 Helm 添加第三方 Chart 库：

[root@k8s-master01 ~]# helm repo add stable http://mirror.azure.cn/kubernetes/charts/"stable" already exists with the same configuration, skipping[root@k8s-master01 ~]# helm repo list
NAME    	URL                                      
bitnami 	https://charts.bitnami.com/bitnami       
dandydev	https://dandydeveloper.github.io/charts  
stable  	http://mirror.azure.cn/kubernetes/charts/

7.3 添加第三库之后就可以使用以下方式查询：

[root@k8s-master01 ~]# helm search repo redis
