+```shell
+helm install --set csi.kubelet.rootDir=<kubelet-root-dir> \
+  --set csi.kubelet.certDir=<kubelet-root-dir>/pki fluid fluid.tgz
+```
+
+> You can execute the following command on the Kubernetes node to view the --root-dir parameter configuration:
+> ```
+> ps -ef | grep $(which kubelet) | grep root-dir
+> ```
+> If the above command has no output, the kubelet root path is the default value (/var/lib/kubelet), which is the default value set by Fluid.

+3. 如果您的Kubernetes集群自定义配置了kubelet root directory，请在安装Fluid时配置KUBELET_ROOTDIR，您可以使用以下命令：
+```shell
+helm install --set csi.kubelet.rootDir=<kubelet-root-dir> \
+  --set csi.kubelet.certDir=<kubelet-root-dir>/pki fluid fluid.tgz
+```
+
+> 您可以在Kubernetes节点上执行如下命令查看--root-dir参数配置情况：

+> ps -ef | grep $(which kubelet) | grep root-dir

+> 如果上述命令未找到对应结果，则说明kubelet根路径为默认值（/var/lib/kubelet），与Fluid设置的默认值一致。
