# RPC generator script
# Converts a normal seed node into an RPC node with Jussi
# (C) 2020 Privex Inc.
#
# Customise the nginx domain, Steem-in-a-box location, and plugin list by exporting
# the vars MYDOM, SIAB, and PLUGINLIST - or just use the defaults if they're applicable :)
# 
# Usage:
#    
#    # Become root. Don't do 'sudo bash' because it will lose your exported variables
#    sudo su -
#    # Export MYDOM / SIAB / PLUGINLIST if needed with custom settings
#    export MYDOM="seed.mydomain.com" SIAB="/root/steem-docker"
#    # Download and run the mkrpc script
#    curl -fsSL https://cdn.privex.io/extras/rpc/mkrpc.sh | bash
#
