二、TimescaleDB  安裝配置

1、安裝數據庫：

2、製作 timescaledb.repo 文件

[root@localhost ~]# sudo vi /etc/yum.repos.d/timescaledb.repo

[timescale_timescaledb]
name=timescale_timescaledb
baseurl=https://packagecloud.io/timescale/timescaledb/el/7/$basearch
repo_gpgcheck=1
gpgcheck=0
enabled=1
gpgkey=https://packagecloud.io/timescale/timescaledb/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300

3、安裝 timescaledb-postgresql-11 

[root@localhost ~]# sudo yum install -y timescaledb-postgresql-11

4、配置數據庫

[root@localhost ~]# sudo timescaledb-tune --pg-config=/usr/pgsql-11/bin/pg_config 

注：如果使用默認配置，可直接使用如下命令

[root@localhost ~]# sudo timescaledb-tune --pg-config=/usr/pgsql-11/bin/pg_config --quiet --yes

5、重啓數據庫服務

[root@localhost ~]# sudo systemctl restart postgresql-11.service

6、測試：

切換用戶：

[root@localhost ~]# su - postgres

進入命令窗口：

-bash-4.2$ psql

創建數據庫 timeseries

postgres=# CREATE DATABASE timeseries;
postgres=# \l

進入創建的數據庫 timeseries

postgres=# \c timeseries
timeseries=# CREATE EXTENSION IF NOT EXISTS timescaledb CASCADE;

創建表：

timeseries=# CREATE TABLE conditions (time TIMESTAMP WITH TIME ZONE NOT NULL,device_id TEXT,temperature NUMERIC,humidity NUMERIC);
timeseries=# SELECT create_hypertable('conditions', 'time');

插入數據：

timeseries=# INSERT INTO conditions(time, device_id, temperature, humidity) VALUES (NOW(), 'weather-pro-000000', 84.1, 84.1);
timeseries=# INSERT INTO conditions VALUES (NOW(), 'weather-pro-000002', 71.0, 51.0),(NOW(), 'weather-pro-000003', 70.5, 50.5),(NOW(), 'weather-pro-000004', 70.0, 50.2);

查詢數據

timeseries=# SELECT * FROM conditions LIMIT 10;

查詢數據

timeseries=# SELECT * FROM conditions ORDER BY time DESC LIMIT 3;
