Install PostgreSql & Apache AGE from Source

This article outlines the steps required to install Apache AGE and AGE-Viewer on a Linux system. The installation involves the following three main steps:

• Installing Postgres from source
• Installing and configuring Apache AGE with Postgres
• Installing AGE-Viewer for Graphs analysis

We will discuss how to install age on Linux. Also there is a video for installing steps

mkdir age_dir
cd age_dir
mkdir pg_dir
cd pg_dir

Before proceeding with the installation, install the necessary dependencies by following the instructions given at
https://age.apache.org/age-manual/master/intro/setup.html#pre-installation

If using Ubuntu, you can install the dependencies by running the command:

sudo apt-get install build-essential libreadline-dev zlib1g-dev flex bison

installing PostgreSql

Next, you will need to install an AGE-compatible version of Postgres (e.g. psql v11.18)
Downloading it and extracting it to the /age_dir/pg

wget https://ftp.postgresql.org/pub/source/v11.18/postgresql-11.18.tar.gz && tar -xvf postgresql-11.18.tar.gz && rm -f postgresql-11.18.tar.gz

then..

cd postgresql-11.18

# configure by setting flags
./configure --enable-debug --enable-cassert --prefix=$(pwd) CFLAGS="-ggdb -Og -fno-omit-frame-pointer"

# now install
make install

# go back
cd ../../

installing AGE

cd age/

# install
sudo make PG_CONFIG=/home/age_installation/pg/postgresql-11.18/bin/pg_config install

# install check
make PG_CONFIG=/home/age_installation/pg/postgresql-11.18/bin/pg_config installcheck

PG_CONFIG require the path to the pg_config file. Give the path from the recently installed PostgreSQL.

DB Initialization

create new database cluster named demo

cd postgresql-11.18/

# intitialization
bin/initdb demo

start server

create new database demodb and start the server

bin/pg_ctl -D demo -l logfile start
bin/createdb demodb

to write queries

bin/psql demodb

Now that you have initialized a new database, you can load the AGE extension in order to start using AGE. Run the following commands:

CREATE EXTENSION age;
LOAD 'age';
SET search_path = ag_catalog, "$user", public;

Installing AGE-Viewer

Finally, to install AGE-Viewer, install Node.js and npm by running the following command:

sudo apt install nodejs npm

cd /age_dir

git clone https://github.com/apache/age-viewer.git

After cloning the repository, navigate to the "age-viewer" directory and set up the environment by running the following commands:

cd age-viewer

npm run setup
npm run start

the app will be running on localhost:3000
