    2.3、创建tidb-operator

C#

create tidb-admin namespace

[root@r21 soft]# kubectl create namespace tidb-admin

create tidb-operator

[root@r21 soft]# kubectl apply -f tidb-operator-deploy.yaml -n tidb-admin2.4、检查tidb-operator状态

Kotlin[root@k8s-master tidb-operator]# kubectl get pods -n tidb-adminNAME READY STATUS RESTARTS AGEtidb-controller-manager-6fb99fdb64-5zssz 1/1 Running 28 13dtidb-scheduler-9f9c785c5-x42b4 2/2 Running 17 29d方法二:通过helm2.1、添加pingcap仓库

C#helm repo add pingcap https://charts.pingcap.org/2.2、创建命名空间

SQLkubectl create namespace tidb-admin2.3、安装tidb-operator

C++helm install --namespace tidb-admin tidb-operator pingcap/tidb-operator --version v1.3.3 \--set operatorImage=registry.cn-beijing.aliyuncs.com/tidb/tidb-operator:v1.3.3 \--set tidbBackupManagerImage=registry.cn-beijing.aliyuncs.com/tidb/tidb-backup-manager:v1.3.3 \--set scheduler.kubeSchedulerImageName=registry.cn-hangzhou.aliyuncs.com/google_containers/kube-scheduler2.4、检查tidb-operator是否正常运行

Kotlin[root@k8s-master tidb-operator]# kubectl get pods --namespace tidb-admin -l app.kubernetes.io/instance=tidb-operatorNAME READY STATUS RESTARTS AGEtidb-controller-manager-6fb99fdb64-5zssz 1/1 Running 28 13dtidb-scheduler-9f9c785c5-x42b4 2/2 Running 17 29d1、创建pv

Groovymount --bind /home/data/data1/ /home/data/data1/mount --bind /home/data/data2/ /home/data/data2/mount --bind /home/data/data3/ /home/data/data3/3、为TiDB Cluster创建PV创建PV有两种方式:一种是人工管理 PV 的方式就叫作 Static Provisioning;另一种可以是Local PV,可使用 local-static-provisioner 项目中的 local-volume-provisioner 程序创建本地存储对象方式一:人工管理Static Provisioning方式3.1、创建PV

YAML1、在不同的work节点上创建不同的目录,有几个计算节点分别在节点上执行for i in seq 9; do mkdir -p /home/data/pv0$i; done2、在K8S的master节点上执行创建pv的语句.

[root@r22 disks]# for i in seq 9; docat <<EOF | kubectl apply -f -apiVersion: v1kind: PersistentVolumemetadata:name: tidb-cluster-r22-pv0${i}spec:capacity:storage: 5GivolumeMode: FilesystemaccessModes:

Fortran##依次在K8S的各个计算节点依次执行1、创建对应的目录mkdir /home/data/{data1,data2,data3}2、依次挂载对应的节点mount --bind /home/data/data1/ /home/data/data1/mount --bind /home/data/data2/ /home/data/data2/mount --bind /home/data/data3/ /home/data/data3/###上述的/home/data/data1、/home/data/data2、/home/data/data13是 local-volume-provisioner使用的发现目录(discovery directory),local-volume-provisioner 会为发现目录下的每一个子目录创建对应的 PV3.2、下载和配置 local-volume-provisioner

YAML1、下载wget https://raw.githubusercontent.com/pingcap/tidb-operator/master/examples/local-pv/local-volume-provisioner.yaml

2、修改不同的路径。如果你使用与上一步中不同路径的发现目录,需要修改 ConfigMap 和 DaemonSet 定义。#cat local-volume-provisioner.yamlapiVersion: storage.k8s.io/v1kind: StorageClassmetadata:name: "local-storage"provisioner: "kubernetes.io/no-provisioner"volumeBindingMode: "WaitForFirstConsumer"
