Quick updates of linux nodes


Recommended Posts

There's a method to update really fast and smooth your linux node. I will try to explain, keep in mind that this tutorial is useful if you had installed the node from the github repository of scripts elrond-go-scripts. If you don't have the node installed from this repository this code can be wrong. I always make the installation of elrond-go-scripts on my home, be careful with the instructions that imply this folder.

1.- Before we start make a copy of your pems:

mkdir ~/backup-pems

cp ~/go/src/github.com/ElrondNetwork/elrond-go-node/config/*pem ~/backup-pems

2.- Close your node:

If you use screen launch you can do: screen -S nameofyourscreen -X quit

3.- Update your scripts repo:

cd ~/elrond-go-scripts/ubuntu-amd64

bash get-github-repo.sh

4.- Update your node from the scripts repo

bash update.sh (I guess that you're in the same folder)

At this point your elrond-go-node is updated, you need to restore your keys

5.- Restore your registered keys:

cp ~/backup-pems/*pem ~/go/src/github.com/ElrondNetwork/elrond-go-node/config

6.- Maybe delete db, logs and stats

Only If the testnet update require to cleanup all this stuff then:

rm -r ~/go/src/github.com/ElrondNetwork/elrond-go-node/db

rm -r ~/go/src/github.com/ElrondNetwork/elrond-go-node/stats

rm -r ~/go/src/github.com/ElrondNetwork/elrond-go-node/logs

7.- Start again your node

I like to launch it on screen but it's up to you:

cd ~/src/github.com/ElrondNetwork/elrond-go-node

screen -AmdS testnet ./node

(it creates a virtual screen with name testnet and the node running inside)

If you want to see the node running

screen -r testnet

If you want to exit the screen without stop your node

Press Ctrl+A and then press D

As a Bonus track, if you never installed from this source it's easy on linux:

1.- Be sure that you have Git installed

sudo apt install git

2.- Clone the repository on your home

cd ~

git clone https://github.com/ElrondNetwork/elrond-go-scripts.git

(This has created a folder elrond-go-scripts in your home)

3.- The first time we install prerequisites

cd ~/elrond-go-scripts/ubuntu-amd64

bash _prerequisite.sh

4.- Install de node

bash install.sh

It will ask you about your Nodename and will create new identity (new pem keys) to you.

You will have when it finish a folder ~/src/github.com/ElrondNetwork/elrond-go-node where is your node ready for run it

5.- Make a backup of your keys just in case

mkdir -p ~/backup-pems

cp ~/src/github.com/ElrondNetwork/elrond-go-node/config/*pem ~/backup-pems

6.- Start your node

You can start your node from the installation or later.

I like to open it as virtual screen with:

cd ~/src/github.com/ElrondNetwork/elrond-go-node/

screen -AmdS testnet ./node

From here, never do install again, always the procedure above about updating nodes.
