Google CloudPlatform 物联网项目之Lora-Server
首先我们找到Lora-Server服务器的地址
https://cloud.google.com/community/tutorials/setting-up-loraserver
或者
https://www.chirpstack.io/
官网推荐的是使用 谷歌VM来创建
注意：创建服务器按照官方文档推荐的方式创建
第一部分网关和网桥的安装
2. 生成密钥
openssl genpkey -algorithm RSA -out rsa_private.pem -pkeyopt rsa_keygen_bits:2048
openssl rsa -in rsa_private.pem -pubout -out rsa_public.pem官方使用的是4096是错误的目前谷歌不支持了所以换成2048的
第一次我碰到这个问题找了几天才解决
从社区提交的Google Cloud社区教程不代表Google Cloud产品的官方文档
3. 上传密钥文件 其中把 rsa_private.pem 文件上传到 谷歌 vm中 并查询一下文件所在的路径 find / -name rsa_private.pem 我的是这个路径 /home/radiancegooplay/rsa_private.pem
4. 安装MQTT sudo apt-get install mosquitto
5. 安装网关网桥 sudo apt-get install chirpstack-gateway-bridge
6. 进入配置文件 sudo vim /etc/chirpstack-gateway-bridge/chirpstack-gateway-bridge.toml
7. 修改配置文件如下
[integration.mqtt.auth]
type="gcp_cloud_iot_core"
[integration.mqtt.auth.gcp_cloud_iot_core]
server="ssl://mqtt.googleapis.com:8883"
device_id="gw-0102030405060708"
project_id="xxxxx"
cloud_region="us-central1"
registry_id="eu868-gateways"
jwt_key_file="/home/radiancegooplay/rsa_private.pem"8. 去GCP中点击 Iot Core中创建注册表 id为 eu868-gateways 区域选择 us-central1 可以按照文档中去做 还可以创建主题这些步骤是必须进行的这个只要细心基本不会出现错误
9. 然后创建设备 设备id命名为 gw-0102030405060708 然后关键的地方在于 设备的 身份验证 把刚创建的 密钥 rsa_public.pem添加设备中去，有两种方式你可以选择其中一种添加 如果不添加将会报通讯失败错误
10. 完成以上步骤后我们首先来测试下 运行 sudo chirpstack-gateway-bridge
如果出现以下代码我们可以看到应该是成功了
xxxx@tmw023-vm:~$ sudo chirpstack-gateway-bridge
INFO[0000] starting ChirpStack Gateway Bridge docs="https://www.chirpstack.io/gateway-bridge/" version=3.8.0
INFO[0000] backend/semtechudp: starting gateway udp listener addr="0.0.0.0:1700"
INFO[0000] integration/mqtt: connected to mqtt broker
然后按 Ctrl+C 退出 再正式的启动 sudo systemctl [start|stop|restart|status] chirpstack-gateway-bridge 运行 sudo systemctl start chirpstack-gateway-bridge 再检查是否成功启动 sudo systemctl status chirpstack-gateway-bridge
没有问题的话 应该是以下的显示
xxxxx@tmw023-vm:~$ sudo systemctl status chirpstack-gateway-bridge

第二部分网关网桥的安装
-
前面一部分基本看文档去做 文档讲解非常好 关键是 创建 functions的时候 一定要执行的函数修改成 Send
-
创建数据库 按照文档的说明去创建就行
启用trgm和hstore扩展 在PostgreSQL实例的“ 概述”选项卡中，单击“ 使用Cloud Shell连接”，然后gcloud sql connect ...在控制台中显示命令 时，按Enter。它将提示您输入postgres用户密码（您在创建PostgreSQL实例时配置的密码）。
然后执行以下SQL命令：
-- change to the ChirpStack Application Server database
\c chirpstack_as
-- enable the pg_trgm extension
-- (this is needed to facilitate the search feature)
create extension pg_trgm;
-- enable the hstore extension
-- (this is needed for storing additional k/v meta-data)
create extension hstore;
-- exit psql
\q
您可以关闭Cloud Shell。
-
安装ChirpStack网络服务器 sudo apt install chirpstack-network-server
-
配置chirpstack-network-server.toml文件 sudo vim /etc/chirpstack-network-server/chirpstack-network-server.toml 修改完成后记得:wq保存
注意： 这个是 ns的千万不能弄错
[postgresql]
dsn="postgres://chirpstack_ns:[PASSWORD]@[POSTGRESQL_IP]/chirpstack_ns?sslmode=disable"
[redis]
url="redis://xxxx:6379"

通过检查我们已经成功的启动了
- 现在我们可以安装ChirpStack应用服务器
执行 sudo apt install chirpstack-application-server
安装完成后还是老样子 配置 chirpstack-application-server.toml文件
sudo vim /etc/chirpstack-application-server/chirpstack-application-server.toml
注意需要增加一个参数 JWT_SECRET 这个你可以通过自己电脑运行 openssl rand -base64 32 随机生成然后复制进去就可以 记得 :wq保存
[postgresql]
dsn="postgres://chirpstack_as:[PASSWORD]@[POSTGRESQL_IP]/chirpstack_as?sslmode=disable"

[application_server.external_api]

现在我们运行测试
sudo chirpstack-application-server
出现以下代码说明运行成功

安装网关桥的时候 一定要提前安装
ChirpStack Gateway Bridge利用MQTT来发布事件和接收命令。Mosquitto是流行的开源MQTT代理，但是任何实现MQTT 3.1.1的MQTT代理都可以使用。如果您安装Mosquitto，请确保您安装了最新版本
sudo apt-get install mosquitto
然后执行安装
安装需要 sudo apt-get install lora-gateway-bridge //这个最后会变为 chirpstack-gateway-bridge
配置 lora-gateway-bridge.toml 安装需要 sudo apt-get install lora-gateway-bridge
配置好之后运行
测试成功的话
sudo chirpstack-gateway-bridge
执行
sudo systemctl [start|stop|restart|status] chirpstack-gateway-bridge
如果没有导入就报以下的错误

关键的处理办法
当出现上面这些错误的时候 第一个想到的是4096的太长了 需要更换成谷歌官方的2048 我还在
有关创建密钥对 请看谷歌文档的介绍
https://cloud.google.com/iot/docs/how-tos/credentials/keys
文档中看到这段话
从社区提交的Google Cloud社区教程不代表Google Cloud产品的官方文档。
所以我更换了 这种形式的
You can generate a 2048-bit RSA key pair with the following commands:
生成私钥
openssl genpkey -algorithm RSA -out rsa_private.pem -pkeyopt rsa_keygen_bits:2048
生成公钥
openssl rsa -in rsa_private.pem -pubout -out rsa_public.pem
果然困惑我二天的问题解决了
期间我咨询过 https://forum.chirpstack.io/top/monthly 开发人员 他们也没有给我找到合适的解决办法 不过我敢肯定这种问题没有引起他们的注意
Tips
试运行
sudo chirpstack-gateway-bridge
查找文件所在的路径
find / -name "filename"
修改文件权限
chmod a+rw private-key.pem
