Nebula Graph 支持通过脚本或 systemd 管理服务。本文详细介绍这两种方式
Nebula Graph 使用脚本`nebula.service`管理服务,包括启动、停止、重启、中止和查看

!!! enterpriseonly
`nebula.service`的默认路径是`/usr/local/nebula/scripts`,如果修改过安装路径,请使用实际路径。

仅企业版支持使用 systemd 管理服务。

这两种方式互不兼容,选择使用其中一种。

## 使用脚本管理服务

使用脚本`nebula.service`管理服务,包括启动、停止、重启、中止和查看。

## 使用 systemd 管理服务

为方便使用,Nebula Graph 支持用 systemd 管理服务,通过`systemctl`启动、停止、重启和查看服务。

!!! note

安装 Nebula Graph 后,systemd 所需的`.service`文件在安装目录的`etc/unit`目录内,使用 RPM/DEB 包安装的 Nebula Graph,会自动将这些`.service`文件放入`/usr/lib/systemd/system`目录内,并且`ExecStart`也会根据指定的 Nebula Graph 安装路径进行生成,因此可以直接使用`systemctl`命令。

其他方式安装 Nebula Graph,需要用户手动将`.service`文件移动到`/usr/lib/systemd/system`目录内,并修改`.service`文件内的`ExecStart`的文件路径,才可以正常使用`systemctl`命令。

### 语法

```bash
$ systemctl <start | stop | restart | status > <nebula | nebula-metad | nebula-graphd | nebula-storaged>
```

Nebula Graph 服务由 Meta 服务、Graph 服务和 Storage 服务共同提供,这三种服务的配置文件都保存在安装目录的`etc`目录内,默认路径为`/usr/local/nebula/etc/`,用户可以检查相应的配置文件排查问题。
