[Ethereum] How to install geth on RPi 3B

go-ethereuminstallationparityraspberry-pi

Raspberry Pi 3B (arm7) with Raspbian (which /etc/debian_version shows as 9.1)
I'm logged in as the user pi.
I'm following instructions from http://raspnode.com/diyEthereumGeth.html.

After installing go under $HOME/bin/go, I'm doing these commands:

cd go-ethereum
my path now includes /home/pi/bin/go/bin
make geth

I also tried sudo make geth and got the same error. Oddly enough, sudo didn't ask me for my password like on other linux machines I work on. At the make command I get these errors:

pi@rpi3b-cr:~/bin/go-ethereum $ make geth
build/env.sh go run build/ci.go install ./cmd/geth
internal/build/azure.go:23:2: cannot find package "github.com/Azure/azure-storage-go" in any of:
/home/pi/bin/go/src/github.com/Azure/azure-storage-go (from $GOROOT)
/home/pi/bin/go-ethereum/build/_workspace/src/github.com/Azure/azure-storage-go (from $GOPATH)
internal/build/pgp.go:27:2: cannot find package "golang.org/x/crypto/openpgp" in any of:
/home/pi/bin/go/src/golang.org/x/crypto/openpgp (from $GOROOT)
/home/pi/bin/go-ethereum/build/_workspace/src/golang.org/x/crypto/openpgp (from $GOPATH)
Makefile:15: recipe for target 'geth' failed
make: *** [geth] Error 1

I also tried:

sudo apt-get install eth and sudo apt-get install ethereum and neither could be found in the package repo.
The error was "unable to locate package geth" or similar.

How do I install geth? Or even Parity? I have not been able to find instructions that work yet.

Thank you! I'm a noob when it comes to installing a node, and to Rpi, although I know a little linux.

I was in the exact same situation and solved this by installing the geth binary directly.

Find the latest arm7 geth binary here
The link address is harder to track down, but it's https://gethstore.blob.core.windows.net/builds/geth-linux-amd64-1.7.3-4bb3c89d.tar.gz
$ wget https://gethstore.blob.core.windows.net/builds/geth-linux-amd64-1.7.3-4bb3c89d.tar.gz
untar it with $ tar -xvf geth-linux-amd64-1.7.3-4bb3c89d.tar.gz
then cd geth-linux-amd64-1.7.3-4bb3c89d
move the binary into your /bin with sudo mv geth /usr/local/bin/
Then make sure you've got it working with $ geth license or $ geth h

1 Set Alias

Your aliases will not work with scripts. As scripts only have to be set up once, you could just encode the full path name of the executable.

Otherwise, you can either:

Create a soft link for geth in $HOME/bin

cd $HOME/bin
ln -s path_to/go-ethereum/build/bin/geth geth

Create a soft link for geth in /usr/local/bin

cd /usr/local/bin
ln -s path_to/go-ethereum/build/bin/geth geth

Use 1. above if you have already created a $HOME/bin directory, if you have executables that you run from it, and your script can access the executables in this directory (if you run the scripts from your user account).

Otherwise use 2. above.

Installation

From Installation Instructions for Ubuntu:

sudo apt-get install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install ethereum

Did you execute all the commands above in the correct order?

[Ethereum] How to monitor and auto-restart geth with monit

I did find a temporary working solution. It restarts geth just fine and sends alerts. But if you want to stop geth here you'll have to unmonitor it first with sudo monit unmonitor geth and then gracefully kill it with -SIGINT signal manually. Otherwise it gets killed with -HUP.

Monit config. /etc/monit/conf.d/geth.cfg

# GETH
CHECK PROCESS geth MATCHING "[g]eth.*fast"
    start program = "/bin/bash -c 'geth --fast --rpc --rpcport 8545 --rpccorsdomain localhost --cache=16 >/dev/null 2> /home/my-logs-folder/geth.log'" as uid username as gid username
    stop program = "/bin/bash -c 'kill -HUP $(ps aux | grep '[g]eth' | awk '{print $2}')'" as uid username as gid username
    if not exist then alert
    if not exist then restart

I believe the better approach is the script cited in the question, so I'm not marking this as the answer.
