Commercio.network testnet 6001 Update

ATTENTION: This guide is only for updating from commercio-testnet5000 or commercio-testnet6000 (failed chain) to commercio-testnet6001 and for full nodes or validators that have followed the instructions reported here Installing a full node

The upgrade is scheduled for 16.00 CET (15.00 UTC) on Friday 07/02/2020

BEFORE YOU START

After genesis time the chain may not be started immediately: if the consensus is not reached, the first block will not be released.
It is important that 2/3 of the validator nodes must be on-line.

1. Update from commercio-testnet6000

1. Get chain data

systemctl stop cnd
pkill cncli
cd ~/
rm -rf commercio-chains
mkdir commercio-chains && cd commercio-chains
git clone https://github.com/commercionetwork/chains.git .
cd commercio-testnet6001

Update your CHAINID

export CHAINID=commercio-$(cat .data | grep -oP 'Name\s+\K\S+')
sed -ie "s|CHAINID=\".*\"|CHAINID=\"$CHAINID\"|g" ~/.profile

Test if you have the correct binaries version:

cnd version

Should output the same version written inside the .data file: v1.4.0
Use this command to control it

cat .data | grep -oP 'Release\s+\K\S+'

2. Install new chain

Reset chain and install new genesis:

cnd unsafe-reset-all
cp genesis.json ~/.cnd/config

Change the persistent peers inside config.toml file

sed -e "s|persistent_peers = \".*\"|persistent_peers = \"$(cat .data | grep -oP 'Persistent peers\s+\K\S+')\"|g" ~/.cnd/config/config.toml > ~/.cnd/config/config.toml.tmp
mv ~/.cnd/config/config.toml.tmp  ~/.cnd/config/config.toml

Change the seeds inside the config.toml file

sed -e "s|seeds = \".*\"|seeds = \"$(cat .data | grep -oP 'Seeds\s+\K\S+')\"|g" ~/.cnd/config/config.toml > ~/.cnd/config/config.toml.tmp
mv ~/.cnd/config/config.toml.tmp  ~/.cnd/config/config.toml

3. Start your node

systemctl start cnd

Control if the node was started. Use Ctrl + C to interrupt the tail command

tail -100f /var/log/syslog

Output should be like below if you start the chain before the genesis time

#Feb 07 10:38:33 yournodehost cnd[25314]: I[2020-02-07|10:38:33.401] starting ABCI with Tendermint                module=main

Update cncli config

cncli config chain-id $CHAINID

2. Quick update from commercio-testnet5000

1. Install binaries

systemctl stop cnd
pkill cncli
cp -r ~/go/bin ~/go/bin.1.3.3
cd ~/go/bin
wget "https://github.com/commercionetwork/commercionetwork/releases/download/v1.4.0/Linux-AMD64.zip"
unzip -o Linux-AMD64.zip 
rm -rf Linux-AMD64.zip

2. Get chain data

cd ~/
rm -rf commercio-chains
mkdir commercio-chains && cd commercio-chains
git clone https://github.com/commercionetwork/chains.git .
cd commercio-testnet6001

Update your CHAINID

export CHAINID=commercio-$(cat .data | grep -oP 'Name\s+\K\S+')
sed -ie "s|CHAINID=\".*\"|CHAINID=\"$CHAINID\"|g" ~/.profile

Test if you have the correct binaries version:

cnd version

Should output the same version written inside the .data file: v1.4.0
Use this command to control it

cat .data | grep -oP 'Release\s+\K\S+'

3. Backup your .cnd folder and install new chain

Cancel previous backup if you have it

rm -rf ~/.cnd.save

Save state of commercio-testnet5000

cp -r ~/.cnd ~/.cnd.save

Reset chain and install new genesis:

cnd unsafe-reset-all
cp genesis.json ~/.cnd/config

Change the persistent peers inside config.toml file

sed -e "s|persistent_peers = \".*\"|persistent_peers = \"$(cat .data | grep -oP 'Persistent peers\s+\K\S+')\"|g" ~/.cnd/config/config.toml > ~/.cnd/config/config.toml.tmp
mv ~/.cnd/config/config.toml.tmp  ~/.cnd/config/config.toml

Change the seeds inside the config.toml file

sed -e "s|seeds = \".*\"|seeds = \"$(cat .data | grep -oP 'Seeds\s+\K\S+')\"|g" ~/.cnd/config/config.toml > ~/.cnd/config/config.toml.tmp
mv ~/.cnd/config/config.toml.tmp  ~/.cnd/config/config.toml

4. Start your node

systemctl start cnd

Control if the node was started. Use Ctrl + C to interrupt the tail command

tail -100f /var/log/syslog

Output should be like below if you start the chain before the genesis time

#Feb 07 10:38:33 yournodehost cnd[25314]: I[2020-02-07|10:38:33.401] starting ABCI with Tendermint                module=main

Update cncli config

cncli config chain-id $CHAINID

3. Slow update from commercio-testnet5000

1. Install requirements

In order to update the OS so that you can work properly, execute the following commands:

apt update && apt upgrade -y
snap refresh go

2. Get chain data

Before update the node, get commercio-testnet6000 chain data

cp -r ~/go/bin ~/go/bin.1.3.3
rm -rf commercio-chains
mkdir commercio-chains && cd commercio-chains
git clone https://github.com/commercionetwork/chains.git .
cd commercio-testnet6001

3. Install binaries, genesis file and setup configuration

Compile binaries

systemctl stop cnd
pkill cncli
git init . 
git remote add origin https://github.com/commercionetwork/commercionetwork.git
git pull
git checkout tags/$(cat .data | grep -oP 'Release\s+\K\S+')
make install

Test if you have the correct binaries version:

cnd version

Should output the same version written inside the .data file: v1.4.0
Use this command to control it

cat .data | grep -oP 'Release\s+\K\S+'

Update CHAINID:

export CHAINID=commercio-$(cat .data | grep -oP 'Name\s+\K\S+')
sed -ie "s|CHAINID=\".*\"|CHAINID=\"$CHAINID\"|g" ~/.profile

4. Backup your .cnd folder and install new chain

Cancel previous backup if you have it

rm -rf ~/.cnd.save

Save state of commercio-testnet5000

cp -r ~/.cnd ~/.cnd.save

Reset chain and install new genesis:

cnd unsafe-reset-all
cp genesis.json ~/.cnd/config

Change the persistent peers inside config.toml file

sed -e "s|persistent_peers = \".*\"|persistent_peers = \"$(cat .data | grep -oP 'Persistent peers\s+\K\S+')\"|g" ~/.cnd/config/config.toml > ~/.cnd/config/config.toml.tmp
mv ~/.cnd/config/config.toml.tmp  ~/.cnd/config/config.toml

Change the seeds inside the config.toml file

sed -e "s|seeds = \".*\"|seeds = \"$(cat .data | grep -oP 'Seeds\s+\K\S+')\"|g" ~/.cnd/config/config.toml > ~/.cnd/config/config.toml.tmp
mv ~/.cnd/config/config.toml.tmp  ~/.cnd/config/config.toml

5. Start your node

systemctl start cnd

Control if the sync was started. Use Ctrl + C to interrupt the tail command

tail -100f /var/log/syslog

Output should be like below if you start the chain before the genesis time

#Feb 07 10:38:33 yournodehost cnd[25314]: I[2020-02-07|10:38:33.401] starting ABCI with Tendermint                module=main

Update cncli config

cncli config chain-id $CHAINID
