Tutorial – Timescaledb Installation

On the Linux console, use the following commands to check your Ubuntu codename.

# lsb_release -c -s

In our example, Ubuntu 18.04 codename is bionic.

Take note of this information.

On the Linux console, use the following commands to add the PostgreSQL APT repository

# 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”

Now, you need to add the Timescaledb APT repository

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

Use the following command to install TimescaleDB.

# apt-get install timescaledb-postgresql-11

Use the following command to update your postgresql.conf file to include the Timescaledb library.

# timescaledb-tune

The timescaledb-tune command will start to propose configurations tunning to PostgreSQL.

Press enter Y for all change proposals.
