# Alluxio集成NFS作为底层存储

该指南介绍如何配置Alluxio以使用[NFS](http://nfs.sourceforge.net)作为底层文件系统。

## 初始步骤

首先，本地要有Alluxio二进制包。你可以自己[编译Alluxio](/os-cn/contributor/building-alluxio-from-source.md)，或者[下载二进制包](/os-cn/deploy/running-alluxio-locally.md)

## 配置Alluxio

您需要修改`conf/alluxio-site.properties`配置Alluxio，以使用NFS作为其底层存储系统。如果该配置文件不存在，请从模板创建该配置文件。

```console
$ cp conf/alluxio-site.properties.template conf/alluxio-site.properties
```

假定所有NFS客户端与Alluxio部署在同样的节点上，且NFS挂载在`/mnt/nfs`，那以下的环境变量要添加到`conf/alluxio-site.properties`配置文件中：

```
alluxio.master.hostname=localhost
alluxio.master.mount.table.root.ufs=/mnt/nfs
```

## 使用NFS运行Alluxio

简单地运行以下命令来启动Alluxio文件系统：

```console
$ ./bin/alluxio format
$ ./bin/alluxio-start.sh local
```

要验证Alluxio是否正在运行，你可以访问\*\*<http://localhost:19999>\*\*，或者查看`logs`下的日志。

接着，你可以运行一个简单的示例程序：

```console
$ ./bin/alluxio runTests
```

运行成功后，访问你的NFS volume，确认其中包含了由Alluxio创建的文件和目录。在该测试中，创建的文件名称应像下面这样：

```
/mnt/nfs/default_tests_files/Basic_CACHE_THROUGH
```

你可以在任何时间运行以下命令停止Alluxio：

```console
$ ./bin/alluxio-stop.sh local
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://documentation.alluxio.io/os-cn/ufs/nfs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
