教程 - Timescaledb安装

在Linux控制台上，使用以下命令检查您的Ubuntu代号。

# lsb_release -c -s

在我们的例子中，Ubuntu 18.04代号是仿生的。

记下这些信息。

在Linux控制台上，使用以下命令添加PostgreSQL APT存储库

# apt-get install software-properties-common
# apt-key adv --keyserver keyserver.ubuntu.com --recv-keys B97B0AFCAA1A47F044F244A07FCC7D46ACCC4CF8
# add-apt-repository "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -c -s`-pgdg main"

现在，您需要添加Timescaledb APT存储库

# add-apt-repository ppa:timescale/timescaledb-ppa
# apt-get update

使用以下命令安装TimescaleDB。

# apt-get install timescaledb-postgresql-11

使用以下命令更新postgresql.conf文件以包含Timescaledb库。

# timescaledb-tune

timescaledb-tune命令将开始提出调整到PostgreSQL的配置。

按Enter键输入所有更改提案。

Saving changes to: /etc/postgresql/11/main/postgresql.con

使用以下命令重新启动PostgreSQL服务。

# service postgresql restart

使用以下命令检查PostgreSQL服务的状态

# service postgresql status

以下是PostgreSQL服务状态输出的示例。
