5. 执行命令创建定时任务
   
   ```shell
   $ bash create-task.sh
     [ ok ] Reloading configuration files for periodic command scheduler: cron.
   ```

## 配置

`config.json` 的配置，ipv4是要设置解析的域名。

```json
{
  "$schema": "https://ddns.newfuture.cc/schema/v2.8.json",
  "debug": false,
  "dns": "alidns",
  "id": "阿里云RAM的AccessKey",
  "index4": "url:http://ip.sb",
  "index6": "default",
  "ipv4": [
    "要进行解析的完整域名"
  ],
  "ipv6": [],
  "proxy": null,
  "token": "阿里云RAM的AccessKeySecret",
  "ttl": null
}
```

`create-task.sh`

```bash
#!/usr/bin/env bash
RUN_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )";

CMD="\"$RUN_DIR/ddns\" -c \"$RUN_DIR/config.json\" >> \"$RUN_DIR/run.log\"";

echo "*/5 * * * *   root    $CMD" > /etc/cron.d/ddns;
/etc/init.d/cron reload;
```
