通用配置文件
主配置问及那用于连接到ThingsBoard平台实例和启用/禁用连接器。这配置文件只想ThingsBoard实例并使用配置为存储最多100000条记录的内存文件存储。有4个不同的连接器处于活动状态。如果您只想使用其中之一，只需移除所有其他连接器。
主配置文件样例：

安全子模块“security”
三种不同的安全配置
访问令牌（Access Token）
登录您的ThingsBoard平台来获取访问令牌。首先进入到设备选项卡（设备为网关的）
| 参数 | 默认值 | 描述 |
| accessToken | PUT_YOUR_GW_ACCESS_TOKEN_HEAR | 来自ThingsBoard服务器的网关的访问令牌 |
安全子模块的配置如下所示：
...
security:
accessToken: PUT_YOUR_GW_ACCESS_TOKEN_HERE
...安全传输协议 + 访问令牌（TLS + Access Token）
| 参数 | 默认值 | 描述 |
| accessToken | PUT_YOUR_GW_ACCESS_TOKEN_HEAR | 来自 ThingsBoard服务器的网关访问令牌 |
| caCert | /etc/thingsboard-gateway/mqttserver.pub.pem | CA证书文件 |
安全子模块的配置如下所示：
security:
accessToken: PUT_YOUR_GW_ACCESS_TOKEN_HERE
caCert: /etc/thingsboard-gateway/mqttserver.pub.pem安全传输协议 + 私钥（TLS + Private Key）
| 参数 | 默认值 | 描述 |
| caCert | /etc/thingsboard-gateway/ca.pem | CA证书文件 |
| privateKey | /etc/thingsboard-gateway/privateKey.pem | 私钥文件 |
| cert | /etc/thingsboard-gateway/certificate.pem | 证书文件 |
安全子模块的配置如下所示：
security:
privateKey: /etc/thingsboard-gateway/privateKey.pem
caCert: /etc/thingsboard-gateway/ca.pem
cert: /etc/thingsboard-gateway/certificate.pem存储配置
存储模块配置提供了在将传入数据发送到ThingsBoard平台之前保存传入数据的相关配置。其中有两种存储方式：内存和文件
1. 内存存储 - 接收到的数据存储到内存中
2. 文件存储 - 接收到的数据存储到硬盘中
内存存储(磁盘空间充足时建议使用该方式)
| 参数 | 默认值 | 描述 |
| type | memory | 存储类型（存储到内存） |
| read_records_count | 10 | 从存储中获取并发送到ThingsBoard的消息数量 |
| max_records_count* | 100 | 发送到ThingsBoard之前存储的最大数据量 |
备注：如果接收到的数据超过最大存储最大值，新的数据将会丢失
存储模块配置如下所示：
storage:
type: memory
read_records_count: 10
max_records_count: 1000文件存储（需要持久化保存的建议使用该方式）
| 参数 | 默认值 | 描述 |
| type | file | 存储类型（存储到硬盘） |
| data_folder_path | ./data/ | 文件路径 |
| max_file_count | 5 | 将会保存的最大文件数 |
| max_read_records_count* | 6 | 从存储中获取并发送到ThingsBoard的消息数量 |
| max_records_per_file | 14 | 每个文件存储的最大记录数 |
备注：如果接收到的数据超过最大存储最大值，新的数据将会丢失
存储模块的配置如下所示：
storage
type: file
data_folder_path: ./data/
max_file_count: 5
max_read_records_count: 6
max_records_per_file: 14连接器配置
通过实现不同协议连接到设备的配置，每种连接器的配置参数如下表所示：
| 参数 | 默认值 | 描述 |
| name | MQTT Broker Connector | 连接到broker的连接器名称 |
| type | mqtt | 连接器类型 |
| configuration | mqtt.json | 配置文件的名字 |
