##            Quick Primer on addnode vs connect            ##
##  Let's say for instance you use addnode=4.2.2.4          ##
##  addnode will connect you to and tell you about the      ##
##    nodes connected to 4.2.2.4.  In addition it will tell ##
##    the other nodes connected to it that you exist so     ##
##    they can connect to you.                              ##
##  connect will not do the above when you 'connect' to it. ##
##    It will *only* connect you to 4.2.2.4 and no one else.##
##                                                          ##
##  So if you're behind a firewall, or have other problems  ##
##  finding nodes, add some using 'addnode'.                ##
##                                                          ##
##  If you want to stay private, use 'connect' to only      ##
##  connect to "trusted" nodes.                             ##
##                                                          ##
##  If you run multiple nodes on a LAN, there's no need for ##
##  all of them to open lots of connections.  Instead       ##
##  'connect' them all to one node that is port forwarded   ##
##  and has lots of connections.                            ##
##       Thanks goes to [Noodle] on Freenode.               ##

# If no rpcpassword is set, rpc cookie auth is sought. The default `-rpccookiefile` name
# is .cookie and found in the `-datadir` being used for bitcoind. This option is typically used
# when the server and client are run as the same user.
#
# If not, you must set rpcuser and rpcpassword to secure the JSON-RPC api. The first
# method(DEPRECATED) is to set this pair for the server and client:
rpcuser=user

rpcpassword=password

# How many seconds mvc will wait for a complete RPC HTTP request.
# after the HTTP connection is established. 
#rpcclienttimeout=30

# By default, only RPC connections from localhost are allowed.
# Specify as many rpcallowip= settings as you like to allow connections from other hosts,
# either as a single IPv4/IPv6 or with a subnet specification.

# NOTE: opening up the RPC port to hosts outside your local trusted network is NOT RECOMMENDED,
# because the rpcpassword is transmitted over the network unencrypted.

# server=1 is read by mvcd to determine if RPC should be enabled 
rpcallowip=0.0.0.0/0

# Listen for RPC connections on this TCP port:

1. chmod 777 ./install-node.sh
2. ./install-node.sh -t –latest

启动节点，注意user:password需修改为mvc.conf中的rpcuser rpcpassword一致
