How to run GRAND50 node: Instructions for users.
NOTE: The following information is applicable to Ubuntu 16.04 (LTS) or 16.10 — x86_64.
For making process simplier, you can use tools/install_ubuntu_dependencies.sh script.
-
Tool chain components — Used for compiling dependencies
sudo apt-get install -y python build-essential curl automake autoconf libtool -
Git (https://github.com/git/git) — Used for cloning and updating GRAND50
sudo apt-get install -y git -
Node.js (https://nodejs.org/) — Node.js serves as the underlying engine for code execution
System wide via package manager:
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash - sudo apt-get install -y nodejsLocally using nvm:
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash nvm install v10.14.2 -
Install PostgreSQL (version 9.6.2):
sudo apt-get purge -y postgres* sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" > /etc/apt/sources.list.d/pgdg.list' wget -q https://www.postgresql.org/media/keys/ACCC4CF8.asc -O - | sudo apt-key add - sudo apt-get update sudo apt-get install -y postgresql postgresql-contrib libpq-dev # Create user if you are working from superuser adduser grand50 sudo usermod -aG sudo grand50 su - grand50 # Create db sudo -u postgres createuser --createdb $USER createdb grand50_test createdb grand50_main sudo -u postgres psql -d grand50_test -c "alter user "$USER" with password 'password';" sudo -u postgres psql -d grand50_main -c "alter user "$USER" with password 'password';" -
PM2 (https://github.com/Unitech/pm2) — PM2 manages the node process for GRAND50 (Optional)
sudo npm install -g pm2
Clone the GRAND50 repository using Git and initialize the modules.
git clone https://github.com/Grand50-im/grand50
cd grand50
npm install
Alternative way to install GRAND50 with prerequisites. You need only Git installed locally. Or instead of cloning you can download and unpack zip from GitHub.
# Create user
adduser grand50
sudo usermod -aG sudo grand50
su - grand50
git clone https://github.com/Grand50-im/grand50
cd grand50
sh tools/install_ubuntu_dependencies.sh
sudo -u postgres createuser --createdb $USER
createdb grand50_test
createdb grand50_main
sudo -u postgres psql -d grand50_test -c "alter user "$USER" with password 'password';"
sudo -u postgres psql -d grand50_main -c "alter user "$USER" with password 'password';"
npm install
To test that GRAND50 is built and configured correctly, run the following command:
node app.js
Once the process is verified as running correctly, CTRL+C and start the process with pm2. This will fork the process into the background and automatically recover the process if it fails.
pm2 start --name grand50 app.js
After the process is started, its runtime status and log location can be retrieved by issuing the following command:
pm2 show grand50
To stop GRAND50 after it has been started with pm2, issue the following command:
pm2 stop grand50
NOTE: The port, address and config-path can be overridden by providing the relevant command switch:
pm2 start --name grand50 app.js -- -p [port] -a [address] -c [config-path]
Before running any tests, please ensure GRAND50 is configured to run on the same testnet that is used by the test-suite.
Replace config.json and genesisBlock.json with the corresponding files under the test directory:
cp test/config.json test/genesisBlock.json .
NOTE: If the node was started with a different genesis block previous, trauncate the database before running tests.
dropdb grand50_test
createdb grand50_test
NOTE: The master passphrase for this genesis block is as follows:
wagon stock borrow episode laundry kitten salute link globe zero feed marble
Launch GRAND50 (runs on port 36667):
node app.js
Run the test suite:
npm test
Run individual tests:
npm test -- test/lib/accounts.js
npm test -- test/lib/transactions.js
