## 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. ##

Use as many addnode= settings as you like to connect to specific peers addnode=node.mvc.space:29883

Alternatively use as many connect= settings as you like to connect ONLY to specific peers #connect=

Listening mode, enabled by default except when 'connect' is being used #listen=1

Maximum number of inbound+outbound connections. maxconnections=12

# JSON-RPC options (for controlling a running Bitcoin/bitcoind process) #

server=1 tells bitcoind to accept JSON-RPC commands server=1

Bind to given address to listen for JSON-RPC connections. Use [host]:port notation for IPv6. # This option can be specified multiple times (default: bind to all interfaces) rpcbind=0.0.0.0

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: rpcport=9882

minimumchainwork=0000000000000000000000000000000000000000000000000000000100010001
```

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

```
配置cli命令
