cd $HOME 
wget "<https://golang.org/dl/go$ver.linux-amd64.tar.gz>" 
sudo rm -rf /usr/local/go 
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz" 
rm "go$ver.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile

3) Check Go version:

go version

4) Download the binary file:

cd $HOME 
rm -rf celestia-node 
git clone <https://github.com/celestiaorg/celestia-node.git> 
cd celestia-node/ 
git checkout tags/v0.11.0
make build 
make install 
make cel-key

5) Check celestia version:

6) Create key for node (change “f5nodes” when configuring):

• Create a new key

./cel-key add **f5nodes** --keyring-backend test --node.type bridge --p2p.network mocha

• Restore an existing key using a mnemonic (optional)

./cel-key add f5nodes --keyring-backend test --node.type bridge --p2p.network mocha --recover
