1 Gateway Bridge
1.1 生成配置文件
生成默认配置文件，我比较喜欢放在当前工程目录。目前没使用 basic station 的话，倒是没什么好改的。
代码语言：javascript复制# ./build/lora-gateway-bridge configfile > lora-gateway-bridge.toml
# vim lora-gateway-bridge.toml1.2 启动 mqtt broker
代码语言：javascript复制./build/lora-gateway-bridge
INFO[0000] starting LoRa Gateway Bridge docs="https://www.loraserver.io/lora-gateway-bridge/" version=3.0.0-test.3
INFO[0000] backend/semtechudp: starting gateway udp listener addr="0.0.0.0:1700"
ERRO[0000] integration/mqtt: connection error error="Network Error : dial tcp 127.0.0.1:1883: connect: connection refused"修改 mosquitto 的配置文件，启用默认监听端口1883。然后启动服务。
代码语言：javascript复制# vim /etc/mosquitto/mosquitto.conf
# systemctl start mosquitto1.3 运行
代码语言：javascript复制# ./build/lora-gateway-bridge

2.1 postgresql 帐户登录
代码语言：javascript复制# psql -h localhost -U loraserver_ns -W loraserver_ns Password for user loraserver_ns:
psql: FATAL: Ident authentication failed for user "loraserver_ns"明明按照教程一步步设置了密码，怎么就不行了呢？
By default PostgreSQL uses IDENT-based authentication and this will never allow you to login via -U and -W options. Allow username and password based authentication from your application by appling ‘trust’ as the authentication method for the JIRA database user. You can do this by modifying the pg_hba.conf file.
原来默认情况下，不能使用 -U -W 选项进行登录。为此，我们需要将 pg_hba.conf 中的认证方法调整为 ‘trust’。
代码语言：javascript复制# find / -name pg_hba.conf/var/lib/docker/volumes/loraserver-docker_postgresqldata/_data/pg_hba.conf
/var/lib/pgsql/11/data/pg_hba.conf
# vim /var/lib/docker/volumes/loraserver-docker_postgresqldata/_d
ata/pg_hba.conf参考下 loraserver-docker 的配置：
代码语言：javascript复制# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres trust
#host replication postgres 127.0.0.1/32 trust
#host replication postgres ::1/128 trust
host all all all trust# vim /var/lib/pgsql/11/data/pg_hba.conf
# systemctl restart postgresql-11
# psql -h localhost -U loraserver_ns -W loraserver_ns
Password for user loraserver_ns:
psql (9.2.24, server 11.2)
WARNING: psql version 9.2, server version 11.0.
Some psql features might not work.
Type "help" for help.
loraserver_ns=>2.2 配置文件修改
生成默认配置文件，我比较喜欢放在当前工程目录。然后修改之。
代码语言：javascript复制# ./build/loraserver configfile > loraserver.toml
# vim loraserver.toml改两处地方，我的 postgres 是对照官方的初始配置来的：
代码语言：javascript复制[postgresql]
dsn="postgres://loraserver_ns:dbpassword@localhost/loraserver_ns?sslmode=disable"
[network_server.band]
name="CN_470_510"2.3 运行
如果提示这个，说明 MQTT broker 还没起来。参照 1.2 的方式，处理一下。
代码语言：javascript复制# ./build/loraserver

3.1 启动 Redis
可以参考笔记Redis 学习笔记 2.2.1 Redis配置成系统服务（CentOS7）
3.2 配置文件修改
生成默认配置文件，然后修改之。
代码语言：javascript复制# ./build/lora-app-server configfile > lora-app-server.toml
# vim lora-app-server.toml改两处地方，第一处是 postgres，是对照官方的初始配置来的：
代码语言：javascript复制[postgresql]
dsn="postgres://loraserver_as:dbpassword@localhost/loraserver_as?sslmode=disable"第二处是 jwt_secret，使用 openssl rand -base64 32 命令来生成一个随机数：
代码语言：javascript复制# openssl rand -base64 32
Jlc1V0SmAWcwkyNOUnJQtHeQILieIGkc47AQ U2yWLY=
# vim lora-app-server.toml # JWT secret used for api authentication / authorization
# You could generate this by executing 'openssl rand -base64 32' for example
jwt_secret="Jlc1V0SmAWcwkyNOUnJQtHeQILieIGkc47AQ U2yWLY="3.3 运行
代码语言：javascript复制# ./build/lora-app-server

3.4 AS 中关联 NS
由于最新的 backend 规范中，AS 可以关联多个 NS，因此在 AS 界面中需要先配置NS，这里填入本机NS即可。
4 小结
至此，三个组件都已配置启动。
