Migration 1.4.0

For Linux Distributions using prebuild binary

Download the tar.gz file:

curl -LO https://github.com/chain4energy/c4e-chain/releases/download/v1.4.0/c4ed_v1.4.0_linux_amd64.tar.gz

Verify the checksum:

sha256sum c4ed_v1.4.0_linux_amd64.tar.gz

You should see the following:

88a697209e815e31ca422d42f1726ba87cada3904202bbe6994e06db2144e6c0  c4ed_v1.4.0_linux_amd64.tar.gz

Unpack the tar.gz file:

tar -xvf c4ed_v1.4.0_linux_amd64.tar.gz

Move the binary to your local bin directory:

mkdir -p ~/go/bin
sudo mv c4ed ~/go/bin

Install wasmvm library

Create a directory for the library

mkdir ~/.c4e-chain/lib

Download the library to the directory

wget https://github.com/CosmWasm/wasmvm/releases/download/v1.5.2/libwasmvm.x86_64.so -P ~/.c4e-chain/lib

Add the library to the path

echo 'export LD_LIBRARY_PATH=/home/$USER/.c4e-chain/lib:$LD_LIBRARY_PATH' >> ~/.profile
source ~/.profile

Check the version

c4ed version

You should see the following:

1.4.0

Add wasmvm path to cosmovisor service

Add the following line to the cosmovisor service file under the [Service] section.
Remember to change user_path to your actual path

Environment="LD_LIBRARY_PATH=/home/user_path/.c4e-chain/lib:$LD_LIBRARY_PATH"

Restart the cosmovisor service

sudo systemctl daemon-reload
sudo systemctl restart cosmovisor

For Linux Distributions by building binary

Clone repository

git clone --depth 1 --branch  v1.4.0  https://github.com/chain4energy/c4e-chain.git

go to repo directory

cd c4e-chain/

Build binary

make install

Check the version

c4ed version

You should see the following:

1.4.0

Setup cosmovisor

Create cosmovisor upgrade dir

export DAEMON_HOME=$HOME/.c4e-chain/
mkdir -p $DAEMON_HOME/cosmovisor/upgrades/v1.4.0/bin

Put binary in proper dir

cp ~/go/bin/c4ed $DAEMON_HOME/cosmovisor/upgrades/v1.4.0/bin

Just to be sure check version

$DAEMON_HOME/cosmovisor/upgrades/v1.4.0/bin/c4ed version
