Distributed Visualization Installation Instructions
===================================================
(1) On the computer hosting the master of the Distributed2Algebra, install the tools node.js + npm (see https://nodejs.org/en/download/)
# Using Ubuntu
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install -y nodejs
One can check successful installation with
ralf@newton1:~$ node -v
v10.16.2
ralf@newton1:~$ npm -v
6.9.0
(2) In the secondo directory, run
make DistributedVisualization
(3) Create a directory
secondo/bin/distributed_logs
(4) Set directory for distributed logs
In the file
secondo/Tools/DistributedVisualization/server/config/development.json
edit the line
"log_location_absolute": "/home/ralf/secondo/bin/distributed_logs
to the path of your distributed_logs directory.
(5) Set host IP address and port for server
In the same file development.json
edit the line
"http_port": 3000,
and set the port to a desired port number exclusively available for this server. This is the server side.
(6) Set host IP address and port for client
In the directory secondo/Tools/DistributedVisualization/client/src/config
edit the file
default.ts
In the line
base_url: "http://localhost:3000"
set IP address and port of the host. This is the client side. Must be the same port as for the server.
Starting the Visualization
==========================
(1) Start the visualization server:
In directory /secondo/Tools/DistributedVisualization/server
npm run start
(2) In a web browser, goto
http://<server IP>:<port>
for example
http://132.176.69.45:3000
It should work once a distributed query has been run.
