Deployment of SolidityNode and FullNode on the same host

Create separate directories for fullnode and soliditynode

    /deploy/fullnode
    /deploy/soliditynode

Create two folders for fullnode and soliditynode.

Clone our latest master branch of https://github.com/litetokens/java-litetokens and extract it to

    /deploy/java-litetokens

Make sure you have the proper dependencies.

  • JDK 1.8 (JDK 1.9+ is not supported yet)
  • On Linux Ubuntu system (e.g. Ubuntu 16.04.4 LTS), ensure that the machine has Oracle JDK 8, instead of having Open JDK 8 in the system. If you are building the source code by using Open JDK 8, you will get Build Failed result.
  • Open UDP ports for connection to the network
  • MINIMUM 2 CPU Cores

Deployment guide

  1. Build the java-litetokens project
    cd /deploy/java-litetokens 
    ./gradlew build
  1. Copy the FullNode.jar and SolidityNode.jar along with config files into the respective directories.
    download your needed config file from https://github.com/litetokens/LitetokensDeployment.
    main_net_config.conf is the config for mainnet, and test_net_config.conf is the config for testnet.
    please rename the config file to `config.conf` and use this config.conf to start fullnode and soliditynode.

    cp build/libs/FullNode.jar ../fullnode
    cp build/libs/SolidityNode.jar ../soliditynode
  1. You can now run your Fullnode using the following command：
      java -jar FullNode.jar -c config.conf // make sure that your config.conf is downloaded from https://github.com/litetokens/LitetokensDeployment
  1. Configure the SolidityNode configuration file. You'll need to edit config.conf to connect to your local FullNode. Change trustNode in node to local 127.0.0.1:50051, which is the default rpc port. Set listen.port to any number within the range of 1024-65535. Please don't use any ports between 0-1024 since you'll most likely hit conflicts with other system services. Also change rpc port to 50052 or something to avoid conflicts. Please forward the UDP port 18888 for FullNode.
    rpc {
      port = 50052
    }
  1. You can now run your SolidityNode using the following command：
    java -jar SolidityNode.jar -c config.conf //make sure that your config.conf is downloaded from https://github.com/litetokens/LitetokensDeployment

Logging and network connection verification

Logs for both nodes are located in /deploy/\*/logs/litetokens.log. Use tail -f /logs/litetokens.log/ to follow along with the block syncing.

You should see something similar to this in your logs for block synchronization:

FullNode

  12:00:57.658 INFO  [pool-7-thread-1] [o.t.c.n.n.NodeImpl](NodeImpl.java:830) Success handle block Num:236610,ID:0000000000039c427569efa27cc2493c1fff243cc1515aa6665c617c45d2e1bf

SolidityNode

  12:00:40.691 INFO  [pool-17-thread-1] [o.t.p.SolidityNode](SolidityNode.java:88) sync solidity block, lastSolidityBlockNum:209671, remoteLastSolidityBlockNum:211823

Stop node gracefully

Create file stop.sh，use kill -15 to close java-litetokens.jar（or FullNode.jar、SolidityNode.jar）. You need to modify pid=ps -ef |grep java-litetokens.jar |grep -v grep |awk '{print $2}' to find the correct pid.

#!/bin/bash
while true; do
  pid=`ps -ef |grep java-litetokens.jar |grep -v grep |awk '{print $2}'`
  if [ -n "$pid" ]; then
    kill -15 $pid
    echo "The java-litetokens process is exiting, it may take some time, forcing the exit may cause damage to the database, please wait patiently..."
    sleep 1
  else
    echo "java-litetokens killed successfully!"
    break
  fi
done
