Commercio.network testnet 6001 Update

ATTENTION: This guide is only for updating from commercio-testnet6001 to commercio-testnet6002 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 21/02/2020

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.

Why backup is not necessary?

Becouse the previus status is relative small and we published it at Quick sync chain status. The previus status is relative about paused chain and it doesn't able to start another chain again. Keep safe only your ~/.cnd/config folder

1. Quick update

1. Install new bineries

systemctl stop cnd
pkill cncli
systemctl stop cncli # Works only if you installed service for rest server
cd ~/go/bin
wget "https://github.com/commercionetwork/commercionetwork/releases/download/v1.5.0/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-testnet6002

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: v1.5.0
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 21 10:38:33 yournodehost cnd[25314]: I[2020-02-21|10:38:33.401] starting ABCI with Tendermint                module=main

Update cncli config

cncli config chain-id $CHAINID

If you need you can start rest server with command

cncli rest-server >/dev/null 2>&1 &

2. Slow update from previus chain

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-testnet6002 chain data

rm -rf commercio-chains
mkdir commercio-chains && cd commercio-chains
git clone https://github.com/commercionetwork/chains.git .
cd commercio-testnet6002

3. Install binaries, genesis file and setup configuration

Compile binaries

systemctl stop cnd
pkill cncli
systemctl stop cncli # Works only if you installed service for rest server
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: v1.5.0
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. 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

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 21 10:38:33 yournodehost cnd[25314]: I[2020-02-21|10:38:33.401] starting ABCI with Tendermint                module=main

Update cncli config

cncli config chain-id $CHAINID

If you need you can start rest server with command

cncli rest-server >/dev/null 2>&1 &
