How to deploy Vexanium BP node

Important Notes

• The minimum server requirements is dual‑core CPU, 4G RAM, 100G hardrive,and the recommended system is 64‑bit ubuntu 18
• Vexanium mainnet cannot be deployed on the same server as the another mainnet, meaning that one server can only deploy one mainnet. This is to prevent unusual errors during deployment.
• Before the deployment of Vexanium node, please get familar with EOS‑related documents, the use of command client and RPC API use for example
• For BP registration, you need get a mainnet account at first.

BP Node Deployment

This is the Vexanium deployment plan based on linux ubuntu.
Preparation
apt-get update && apt-get install -y wget unzip
Download the release file
wget https://vexanium.s3-ap-southeast-1.amazonaws.com/dl/vex1.7.4bin_ubuntu18.zip
Unzip the downloaded file

Setup

Generate a public/private key pair for BP node. Execute the command as follows:
./cleos create key --to-console
Execution result as follows:

Private key: 5J9ZDeDPvsgCqxyHvYagrNKQxWTqQwiiZ5RPbAJ3gyhvvER795a  
Public key: VEX6vJnArfJm7Txiw5uYCRpovNZ3QNw4EXw5Wtk529cWAkViDSwDg  

Public key will be used during BP registration later, that is regproducer.

Get a mainnet account as producer-name with the Public key, for example account producertest.
Excute the following commands to startup bp node
sudo nohup ./nodeos --max-irreversible-block-age -1 --contracts-console --genesis-json ./genesis.json --blocks-dir ./data/blocks --data-dir ./data --chain-state-db-size-mb 1024 --http-server-address 127.0.0.1:80 --p2p-listen-endpoint 0.0.0.0:8090 --max-clients 5 --p2p-max-nodes-per-host 5 --enable-stale-production --producer-name producertest --signature-provider=VEX6vJnArfJm7Txiw5uYCRpovNZ3QNw4EXw5Wtk529cWAkViDSwDg=KEY:5J9ZDeDPvsgCqxyHvYagrNKQxWTqQwiiZ5RPbAJ3gyhvvER795a --plugin eosio::http_plugin --plugin eosio::chain_api_plugin --plugin eosio::producer_plugin --p2p-peer-address 209.97.162.124:8091 39.105.124.20:8092 > nodeos.log 2>&1 &

BP Registration

Create local wallet:
./cleos wallet create --to-console
Import bp account private key to the wallet:
./cleos wallet import --private-key 5J9ZDeDPvsgCqxyHvYagrNKQxWTqQwiiZ5RPbAJ3gyhvvER795a
Execute command to register:
./cleos --url http://209.97.162.124:8080 system regproducer producertest VEX6vJnArfJm7Txiw5uYCRpovNZ3QNw4EXw5Wtk529cWAkViDSwDg https://producertest.com

Please make sure you have already had your own domain for your block producer and already set the website. Like the example above, https://producertest.com should be already live online

There are 2 conditions for block production:

1. Top 21 BPs can produce blocks
2. Local BP node syncronization is complete
