upgrade steps：

  1. download the latest release package, and unzip：
wget 'https://github.com/gxchain/gxb-core/releases/download/v1.0.190318/gxb_1.0.190318-ubuntu-14.04.tar.gz' -O gxb_1.0.190318-ubuntu-14.04.tar.gz && tar zxvf gxb_1.0.190318-ubuntu-14.04.tar.gz
  1. stop witness_node:
kill -s SIGINT $(pgrep witness_node)
  1. start witness_node with your original startup command line(replace the following command line with your custom command line)：
nohup ./programs/witness_node/witness_node xxx &

If you encounter a post-upgrade sync block stop, you need to use block cropping for processing, then replay blockchain

  1. Cutting block
# cut block
./programs/witness_node/witness_node -x 16418371

# remove old snapshot
rm -rf trusted_node/blockchain/object_database
  1. Restart (with parameter --fast-replay)
nohup ./programs/witness_node/witness_node --fast-replay xxx (The parameters are omitted here, each node is started differently)
