1 证书准备

为了让内容可以使用 TLS 进行传输，整个 Stack 需要 cert.pem 和 key.pem。

实际上在 make init 之后，已经自动创建了。

lorawan-stack  Generating certificates
2019/03/15 15:24:06 wrote cert.pem
2019/03/15 15:24:06 wrote key.pem
make[1]: Leaving directory '/home/ubuntu/lorawan-stack'

自签名证书会出现浏览器和OS不信任的情况，导致一些警告或者错误。可以考虑使用 Let’s Encrypt 申请免费的 TLS 证书。

2 频点计划配置

By default, frequency plans are fetched by the stack from the TheThingsNetwork/lorawan-frequency-plans repository. To set a new source:

TTN_LW_FREQUENCY_PLANS_URL allows you to serve frequency plans fetched from a HTTP server.
TTN_LW_FREQUENCY_PLANS_DIRECTORY allows you to serve frequency plans from a local directory.

配置其实支持3种方式：

启动时的命令参数
-c 选项解析 yml文件
环境变量

3 数据库启动

3.1 CockroachDB

CockroachDB 是一个分布式数据库，被用在了项目中的 Identity Server。

具体安装方法点击这里。

cockroach start --http-port 26256 --insecure

3.2 Redis

Redis 是个比较流行的内存数据存储的数据库，在这个项目中也有用到。

具体安装方法点击这里。

redis-server --appendonly yes

4 Identity Server 的初始化及用户创建

必须保证 cockroach 先运行起来。

$ ./ttn-lw-stack is-db init
  INFO Connecting to Identity Server database...
  INFO Detected database CockroachDB CCL v2.1.6 (x86_64-unknown-linux-gnu, built 2019/03/04 23:21:07, go1.10.7)
  INFO Creating database "ttn_lorawan_dev"...
  INFO Creating tables in "ttn_lorawan_dev"...
  INFO Successfully initialized

$ ./ttn-lw-stack is-db create-admin-user --id admin --email admin@localhost
  INFO Connecting to Identity Server database...
Please enter user password:**
Please repeat user password:**
  INFO Creating user...
  INFO Created user

5 OAUTH 客户端注册

5.1 CLI 注册 OAUTH 客户端

$ ./ttn-lw-stack is-db create-oauth-client \
  --id cli \
  --name "Command Line Interface" \
  --owner admin \
  --no-secret \
  --redirect-uri 'local-callback' \
  --redirect-uri 'code'

5.2 Console 注册 OAUTH 客户端

$ ./ttn-lw-stack is-db create-oauth-client \
   --id console --name "Console" \
   --owner admin \
   --redirect-uri 'http://example.com:1885/console/oauth/callback' \
   --redirect-uri 'https://example.com:8885/console/oauth/callback'
  INFO Connecting to Identity Server database...
  INFO Creating OAuth client...
  INFO Created OAuth client                     secret=TQVLMKM2RR26VDCEXSWWEM7CKNS7T4GPB67L32SVXQHW24QGLY7Q

// 这里的 redirect-uri 没想好怎么用，得再深入研究下 OAuth。

6 环境变量

在 docker yaml 文件内，还可以看到定义了一些环境变量。

      - TTN_LW_HTPP_COOKIE_HASH_KEY
      - TTN_LW_HTTP_COOKIE_BLOCK_KEY
      - TTN_LW_CLUSTER_KEYS
      - TTN_LW_FREQUENCY_PLANS_URL
      - TTN_LW_CONSOLE_OAUTH_CLIENT_SECRET
	  
      - TTN_LW_IS_DATABASE_URI=postgres://root@cockroach:26257/${DEV_DATABASE_NAME:-ttn_lorawan}?sslmode=disable
      - TTN_LW_REDIS_ADDRESS=redis:6379
	  
      - TTN_LW_TLS_CERTIFICATE=/run/secrets/cert.pem
      - TTN_LW_CA=/run/secrets/cert.pem
      - TTN_LW_TLS_KEY=/run/secrets/key.pem

为了简单方便，写个脚本。重点把 CONSOLE_OAUTH_CLIENT_SECRET 配置下，以及把证书文件的路径调整一下。

export TTN_LW_COOKIE_HASHKEY=
export TTN_LW_COOKIE_BLOCKKEY=
export TTN_LW_CLUSTER_KEYS=
export TTN_LW_FREQUENCY_PLANS_URL=
export TTN_LW_CONSOLE_OAUTH_CLIENT_SECRET=TQVLMKM2RR26VDCEXSWWEM7CKNS7T4GPB67L32SVXQHW24QGLY7Q

export TTN_LW_IS_DATABASE_URI=postgres://root@localhost:26257/ttn_lorawan_dev?sslmode=disable
export TTN_LW_REDIS_ADDRESS=localhost:6379
export TTN_LW_TLS_CERTIFICATE=/home/ubuntu/lorawan-stack/cert.pem
export TTN_LW_CA=/home/ubuntu/lorawan-stack/cert.pem
export TTN_LW_TLS_KEY=/home/ubuntu/lorawan-stack/key.pem

7 运行

./ttn-lw-stack start

可以在脚本里加上这一句，一起跑起来。
