基于K8S构建云原生数据基础设施平台 KubeBlocks
一、基于Kubekey快速部署K8S集群
如果需要使用playgroup功能，容器运行时必须要使用Docker。

| ipset | 可选，但推荐安装 |
| ipvsadm | 可选，但推荐安装 |
# yum -y install socat conntrack ebtables ipset ipvsadm1.3 使用Kubekey部署多节点K8S集群
1.3.1 Kubekey工具下载
[root@k8s-master01 ~]# curl -sfL https://get-kk.kubesphere.io | sh -[root@k8s-master01 ~]# ls
kk kubekey-v3.0.7-linux-amd64.tar.gz[root@k8s-master01 ~]# mv kk /usr/local/bin/1.3.2 多节点K8S集群部署
参考网址：https://www.kubesphere.io/zh/docs/v3.3/installing-on-linux/introduction/multioverview/
1.3.2.1 创建kk部署K8S集群配置文件
[root@k8s-master01 ~]# kk create config -f k8s.yaml
输出内容如下：

1.3.2.2 执行kk创建k8s集群
[root@k8s-master01 ~]# kk create cluster -f k8s.yaml执行安装结束后：
18:28:03 CST Pipeline[CreateClusterPipeline] execute successfully
Installation is complete.
Please check the result using the command:
kubectl get pod -A二、为K8S集群提供后端持久存储 NFS
2.1 准备硬盘
查看准备的磁盘
[root@nfsserver ~]# lsblk

sda 8:0 0 100G 0 disk
├─sda1 8:1 0 1G 0 part /boot
└─sda2 8:2 0 99G 0 part

└─centos-home 253:2 0 47G 0 lvm /home
sdb 8:16 0 100G 0 disk2.2 安装NFS软件
安装NFS软件，即是客户端也是服务器端
# yum -y install nfs-utils2.3 NFS配置
创建挂载点
# mkdir /netshare格式化硬盘
# mkfs.xfs /dev/sdb编辑文件系统配置文件
# vim /etc/fstab
在文件最后添加此行内容
/dev/sdb /netshare xfs defaults 0 0手动挂载全部分区
# mount -a在本地查看文件系统挂载情况
# df -h
文件系统 容量 已用 可用 已用% 挂载点
/dev/sdb 100G 33M 100G 1% /netshare添加共享目录到配置文件
# vim /etc/exports
# cat /etc/exports
/netshare *(rw,sync,no_root_squash)启动服务及设置开机自启动
# systemctl enable nfs-server
# systemctl start nfs-server2.4 验证
本地验证目录是否共享
# showmount -e
Export list for nfsserver:
/netshare *在k8s master节点验证目录是否共享
# showmount -e 192.168.10.144
Export list for 192.168.10.144:

# showmount -e 192.168.10.144
Export list for 192.168.10.144:
/netshare *2.5 部署存储动态供给
2.5.1 获取资源清单文件
在k8s master节点获取NFS后端存储动态供给配置资源清单文件
# for file in class.yaml deployment.yaml rbac.yaml ; do wget https://raw.githubusercontent.com/kubernetes-incubator/external-storage/master/nfs-client/deploy/$file ; done查看是否下载
# ls

3.1 KubeBlocks介绍
KubeBlocks 这个名字来源于 Kubernetes 和 LEGO 积木，这表明在 Kubernetes 上构建数据库和分析型工作负载既高效又愉快，就像玩乐高玩具一样。KubeBlocks 将顶级云服务提供商的大规模生产经验与增强的可用性和稳定性改进相结合，帮助用户轻松构建容器化、声明式的关系型、NoSQL、流计算和向量型数据库服务。
为什么需要 KubeBlocks？
Kubernetes 已经成为容器编排的事实标准。它利用 ReplicaSet 提供的可扩展性和可用性以及部署提供的推出和回滚功能来管理数量不断增加的无状态工作负载。然而，管理有状态工作负载给 Kubernetes 带来了巨大的挑战。尽管 StatefulSet 提供了稳定的持久存储和唯一的网络标识符，但这些功能对于复杂的有状态工作负载来说远远不够。
为了应对这些挑战，并解决复杂性问题，KubeBlocks 引入了新的 workload——RSM（Replicated State Machines），具有以下能力：
- 基于角色的更新顺序可减少因升级版本、缩放和重新启动而导致的停机时间。
- 维护数据复制的状态，并自动修复复制错误或延迟。
它带来什么收益？
- KubeBlocks 具备构建数据库专业能力，实现了数据库服务容器化的技术壁垒，达到“开箱即用”数据库服务能力。
- KubeBlocks 使数据库服务在Kubernetes中具备自动化运维的专业能力，不仅简化了数据库的云化改造，也使数据库应用交付更加快速和可靠。

KubeBlocks 支持创建两种类型的 MySQL 集群：Standalone 和 RaftGroup Cluster。Standalone仅支持一份副本，可用于对可用性要求较低的场景。对于可用性要求较高的场景，建议创建RaftGroup集群，即创建一个三副本集群。并且为了保证高可用性，所有副本默认分布在不同的节点上。
创建一个独立的,本次部署名称为:mysql-cluster1,如果需要被监控需要使用--monitoring-interval=15
# kbcli cluster create mysql <clustername>创建 RaftGroup 集群
