ubuntu 16.04 安装 postgresql 10 并 配置成loraserver需要的

配置仓库

Create the file /etc/apt/sources.list.d/pgdg.list and add a line for the repository

deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main

su
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -
sudo apt-get update

安装postgresql-10

apt-get install postgresql-10

安装好后， postgresql 会自动创建一个 postgres 的用户，它暂时没有密码
我们通过下面的命令设置密码
su
su postgres
psql
\password


我新建个 dbuser 帐号
postgres=# CREATE USER dbuser WITH PASSWORD '123456';
CREATE ROLE
postgres=# CREATE DATABASE exampledb OWNER dbuser;
CREATE DATABASE
postgres=# GRANT ALL PRIVILEGES ON DATABASE exampledb TO dbuser;
GRANT
\q 


退出后 我想登录了 再试试操作下数据库
psql -U dbuser -d exampledb -h 127.0.0.1
CREATE TABLE wjs ( name text, age integer );
insert into wjs (name, age) values('test0', 23);
insert into wjs (name, age) values('test1', 22);
select * from wjs where age > 20;

参考 命令行方式登录PostgreSQL、创建用户和数据库并赋权

下面正对loraserver进行必要的配置

su
su postgres
psql
create database loraserver_ns owner dbuser;

来到loraserver build目录下

loraserver configfile > loraserver.toml
打开loraserver.toml 然后第一行删掉

dsn="postgres://dbuser:123456@localhost/loraserver_ns?sslmode=disable"

再运行 loraserver后，数据库已经连上了。接下来提示 mqtt 连接失败。
