请检查 anode 服务是否工作正常。 请务必使用 `curl` 命令检查 anode 服务是否正常。`curl '127.0.0.1:6090'` 正常的 anode 服务会返回以下结果。
```bash
curl '127.0.0.1:6090'
curl: (7) Failed to connect to 127.0.0.1 port 6090: Connection refused
```
```bash ```bash

``` ```
如果出现下面的结果，表示 anode 服务不正常。
```bash
curl: (7) Failed to connect to 127.0.0.1 port 6090: Connection refused
```
如果 anode 服务启动/运行不正常，请检查 uWSGI 的运行日志 `/var/log/taos/taosanode/taosanode.log`，检查其中的错误信息，根据错误信息解决响应的问题。
>请勿使用 systemctl status taosanode 检查 taosanode 是否正常
