装置环境
本步骤将领导您如何装置Docker、kubectl、minikube和Helm3。
1.装置Docker。
1.1 执行如下命令，装置Docker。
curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun1.2 执行如下命令，启动Docker。
systemctl start docker2.装置kubectl。
2.1 执行如下命令，下载kubectl文件。
curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl2.2 执行如下命令，赋予可执行权限。
chmod +x ./kubectl2.2. 执行如下命令，挪动到系统目录。
mv ./kubectl /usr/local/bin/kubectl3.装置minikube。
执行如下命令，下载并装置minikube。
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 sudo install minikube-linux-amd64 /usr/local/bin/minikube4.装置Helm3。
4.1 执行如下命令，下载Helm3。
wget https://labfileapp.oss-cn-hangzhou.aliyuncs.com/helm-v3.9.0-linux-amd64.tar.gz4.2 执行如下命令，解压Helm3。
tar -zxvf helm-v3.9.0-linux-amd64.tar.gz4.3 执行如下命令，挪动到系统目录。
mv linux-amd64/helm /usr/local/bin/helm5.装置MySQL。
执行如下命令，装置MySQL。
yum install mysql -y装置配置参数模板的 PolarDB-X
本步骤将领导您如何创立一个简略的Kubernetes集群并部署PolarDB-X Operator ，应用Operator部署一个残缺的配置有参数模板的PolarDB-X集群，具体文档请参考通过Kubernetes装置PolarDB-X 和 配置参数模板 。
1.应用minikube创立Kubernetes集群。
minikube是由社区保护的用于疾速创立Kubernetes测试集群的工具，适宜测试和学习Kubernetes。应用minikube创立的Kubernetes集群能够运行在容器或是虚拟机中，本试验场景以CentOS 7.9上创立Kubernetes为例。
阐明：如果您应用其余操作系统部署minikube，例如macOS或Windows，局部步骤可能略有不同。
1.1 执行如下命令，新建账号galaxykube，并将galaxykube退出docker组中。
minikube要求应用非root账号进行部署，所以您须要新建一个账号。
useradd -ms /bin/bash galaxykube usermod -aG docker galaxykube1.2 执行如下命令，切换到账号galaxykube。
su galaxykube1.3 执行如下命令，进入到home/galaxykube目录。
cd1.4 执行如下命令，启动一个minikube。
阐明：这里咱们应用了阿里云的minikube镜像源以及USTC提供的docker镜像源来减速镜像的拉取。
minikube start --cpus 4 --memory 12288 --nodes=3 --image-mirror-country cn --registry-mirror=https://docker.mirrors.sjtug.sjtu.edu.cn --kubernetes-version 1.23.3返回后果如下，示意minikube曾经失常运行，minikube将主动设置kubectl的配置文件。
1.5 执行如下命令，应用kubectl查看集群信息。
kubectl cluster-info返回如下后果，您能够查看到集群相干信息。
2.部署 PolarDB-X Operator。
2.1 执行如下命令，创立一个名为polardbx-operator-system的命名空间。
kubectl create namespace polardbx-operator-system2.2 执行如下命令，装置PolarDB-X Operator。
helm repo add polardbx https://polardbx-charts.oss-cn-beijing.aliyuncs.com helm install --namespace polardbx-operator-system polardbx-operator polardbx/polardbx-operator --version 1.3.02.3 执行如下命令，查看PolarDB-X Operator组件的运行状况。
kubectl get pods --namespace polardbx-operator-system返回后果如下，请您急躁期待2分钟，期待所有组件都进入Running状态，示意PolarDB-X Operator曾经装置实现。
3.部署参数模板
3.1 执行如下命令，创立parameter-template.yaml。
vim parameter-template.yaml3.2 按i键进入编辑模式，将如下代码复制到文件中，而后按ECS退出编辑模式，输出:wq后按下Enter键保留并退出。

kubectl apply -f parameter-template.yaml3.4 执行如下命令，查看创立好的参数模板。
kubectl get PolarDBXParameterTemplate4.部署 PolarDB-X 集群。
4.1 执行如下命令，创立polardb-x.yaml。
vim polardb-x.yaml4.2 按i键进入编辑模式，将如下代码复制到文件中，而后按ECS退出编辑模式，输出:wq后按下Enter键保留并退出。
阐明：代码最下方蕴含了参数模板的名称。

kubectl apply -f polardb-x.yaml4.4 执行如下命令，查看PolarDB-X集群创立状态。
kubectl get polardbxCluster polardb-x -o wide -w返回后果如下，请您急躁期待七分钟左右，当PHASE显示为Running时，示意PolarDB-X集群曾经部署实现。
4.5 按Ctrl+C键，退出查看PolarDB-X集群创立状态。
连贯 PolarDB-X 集群
1.执行如下命令，查看PolarDB-X集群登录明码。
kubectl get secret polardb-x -o jsonpath="{.data['polardbx_root']}" | base64 -d - | xargs echo "Password: "返回后果如下，您能够查看到PolarDB-X集群登录明码。
2.执行如下命令，将PolarDB-X集群端口转发到3306端口。
阐明：应用MySQL Client形式登录通过k8s部署的PolarDB-X集群前，您须要进行获取PolarDB-X集群登录明码和端口转发。
kubectl port-forward svc/polardb-x 33063.在试验页面，单击右上角的➕图标，创立新的终端二。
4.执行如下命令，连贯PolarDB-X集群。
- 您须要将替换为理论获取到的PolarDB-X集群登录明码。
- 如遇到mysql: [Warning] Using a password on the command line interface can be insecure.ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 0报错，请您稍等一分钟，从新转发端口并连贯PolarDB-X集群即可。
mysql -h127.0.0.1 -Ac -P3306 -upolardbx_root -p<PolarDB-X集群登录明码>5.查看默认参数。
连贯到mysql后，您能够执行上面两条SQL别离查看CN和DN中的参数和它们的默认值，在下一步中咱们将动静批改这两个参数的值。
5.1 执行如下命令，设置显示所有参数。
set show_all_params = true;5.2 执行如下命令，查看CN参数。
参数阐明：
- XPROTO_MAX_DN_CONCURRENT：公有协定单DN最大并发数，默认值是500。
- XPROTO_MAX_DN_WAIT_CONNECTION：公有协定单DN最大建连数，默认值是32。
show global variables like "XPROTO_MAX_DN_CONCURRENT";show global variables like "XPROTO_MAX_DN_WAIT_CONNECTION";5.3 执行如下命令，查看DN参数（须要增加HINT下推SQL）。
参数阐明：
- sync_binlog：同步binog策略，默认值是1。
/*+TDDL:node(0)*/ show global variables like "sync_binlog";动静批改 PolarDB-X 的参数
本步骤将领导您如何动静批改PolarDB-X中的参数，具体文档请见动静批改参数。
1.部署动静参数
1.1 在试验页面，单击右上角的+图标，创立新的终端三。
1.2 在终端三种，执行如下命令，切换到galaxykube用户。
su galaxykube cd1.3 执行如下命令，创立parameter-modify.yaml。
vim parameter-modify.yaml1.4 按i键进入编辑模式，将如下代码复制到文件中，而后按ECS退出编辑模式，输出:wq后按下Enter键保留并退出。
阐明：您能够依据本身需要批改、增加、删除代码中CN或DN参数列表中的参数。

kubectl apply -f parameter-modify.yaml1.6 执行如下命令，查看参数批改的状态，当PHASE为Finished后示意更改曾经实现。
kubectl get PolarDBXParameter test-param2.切换回终端二。稍作期待后，您能够对批改的参数进行验证。
2.1 在终端二中，执行如下命令，设置显示所有参数。
set show_all_params = true;2.2 执行如下命令，验证CN参数批改。
show global variables like "XPROTO_MAX_DN_CONCURRENT";show global variables like "XPROTO_MAX_DN_WAIT_CONNECTION";2.3 执行如下命令，验证DN参数批改。
/*+TDDL:node(0)*/ show global variables like "sync_binlog";您能够看到变量曾经批改为parameter-modify.yaml中所设定的值。
