# How To stake archcoins on raspberry pi with raspbian
########################################################


# Install required Packages:
 ## update apt
> sudo apt-get update 
 ## install packages
> sudo apt-get install -y automake build-essential libcurl4-openssl-dev git zip libssl-dev libdb++-dev libboost-all-dev libqrencode-dev


# Increase Swapfile:
# Raspberry only has 512 MB of Memory, which is not enough to compile arch wallet
# so wee need to enable and increase the raspian default swap file size
# the swap file will be on default path /var/swap
# remember that having a swapfile on a SD card will shorten the live
# of your SD card quickly. But you may disable the swapfile after having compiled
# arch wallet
> sudo nano /etc/dphys-swapfile
# change CONF_SWAPSIZE=100 to CONF_SWAPSIZE=1000

# Save file and close nano
Ctrl-O
Enter
Ctrl-X

# Reload swap settings
> sudo dphys-swapfile setup
> sudo dphys-swapfile swapoff
> sudo dphys-swapfile swapon


# now Download Wallet from official EdgarSoares Github source
> cd
> git clone https://github.com/EdgarSoares/ARCH
# go to src folder of wallet-source
> cd ARCH/src

# compile wallet with
USE_UPNP=- which means no UPnP support, miniupnp not required;
> make -f makefile.unix "USE_UPNP=-"

# wait for roughly 2h to finish compiling… (it took 2h 9minutes on my raspberry)


# Create Wallet config File:
> nano /home/pi/.archcoin/archcoin.conf


# Add to following to the wallet config file:
listen=1
daemon=1
alertnotify=echo %s | mail -s "Archcoin Alert" username@email.com

# check for new nodes at:

# start wallet:
> /home/pi/ARCH/src/archcoind

# Wait for a couple seconds…
# Check if wallet is p and running with
> /home/pi/ARCH/src/archcoind getinfo

 

# Should return something like:

# Now wait for connections…
# This can take some time…
# Recheck with ./archcoind getinfo


# BONUS:
# Script to autorestart, in case wallet crashes:
> nano /home/pi/checkarchwallet.sh

# Insert following:

#Make shell script executable:
> chmod 740 checkarchwallet.sh

# Add script to crontab
> crontab –e

# Add following line to crontab:
30 * * * * /home/pi/checkarchwallet.sh

# This will check every 30 minutes, if wallet is still running. If wallet is not running, it will start the wallet

# You can test run the script:
> /home/pi/checkarchwallet.sh

# If running, it should return something like:
15:54:47: begin checking...
15:54:47: checking archcoind
