# 如何修改节点配置文件

{% hint style="info" %}
本篇提供给源码方式运行节点的社区用户，作为学习交流。
{% endhint %}

编辑 `public`\_`full_node.yaml`，配置文件，可修改以下内容：

* `base.data_dir`: 数据存储目录；
* `full_node_networks[0].listen_address`: peer 监听地址及端口；
* `debug_interface.admission_control_node_debug_port`: DEBUG 端口；
* `debug_interface.metrics_server_port`: 指标获取端口；
* `debug_interface.public_metrics_server_port`: 指标获取端口；
* `api.address`: API 接口地址及端口；

需要修改的内容如下图标注所示：

配置文件内容：

```yaml
base:
    # This is the location Aptos will store its database. It is backed by a dedicated docker volume
    # for persistence.
    data_dir: "/opt/aptos/data"
    role: "full_node"
    waypoint:
        # This is a checkpoint into the blockchain for added security.
        from_file: "/opt/aptos/etc/waypoint.txt"

execution:
    # Path to a genesis transaction. Note, this must be paired with a waypoint. If you update your
    # waypoint without a corresponding genesis, the file location should be an empty path.
    genesis_file_location: "/opt/aptos/etc/genesis.blob"

# Agent Instructions: 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:

```
GET https://wiki.aptos.movemove.org/wen-ti-faq/ru-he-xiu-gai-jie-dian-pei-zhi-wen-jian.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
