比特币学习笔记(三)---配置文件和启动

编译后的几个主要程序

  • bitcoin-qt 客户端图形界面版

  • bitcoind /src/bitcoind Bitcoin简洁命令行版,也是下一步源代码分析的重点(不能与Bitcoin Core同事运行,如果不小心尝试同时运行另外一个客户端,它会提示已经有一个客户端在运行并且自动退出)

  • bitcoin-cli /src/bitcoin-cli Bitcoind的一个功能完备的RPC客户端,可以通过它在命令行查询某个区块信息,交易信息等

  • bitcoin-tx /src/bitcoind 比特币交易处理模块,可以进行交易的查询和创建

我们现阶段主要学习bitcoind这个程序,这个程序的启动参数大致如下

这里面大部分参数都可以省略,转而使用配置文件进行配置,因为使用配置文件更方便些,所以这里我们使用配置文件进行配置,在linux下时,bitcoin.conf的默认路径为$HOME/.bitcoin/bitcoin.conf,我们可以从bitcoin源码的share/examples找到一份样本拷贝过去并进行修改,我的配置文件如下:

##
## bitcoin.conf configuration file. Lines beginning with # are comments.
##

# Network-related settings:

# Note that if you use testnet or regtest, particularly with the options
# addnode, connect, port, bind, rpcport, rpcbind or wallet, you will also
# want to read "[Sections]" further down.

# 在测试网络中运行,而不是在真正的比特币网络.
testnet=1

# Run a regression test network
# regtest=1

# 通过一个 Socks5 代理服务器连接
# proxy=127.0.0.1:9050

# Bind to given address and always listen on it. Use [host]:port notation for IPv6
#bind=<addr>

# Bind to given address and whitelist peers connecting to it. Use [host]:port notation for IPv6
#whitebind=<addr>

##############################################################
## addnode 与 connect 的区别 ##
## ##
## 假设您使用了 addnode=4.2.2.4 参数,那么 addnode 便会与 ##
## 您的节点连接,并且告知您的节点所有与它相连接的其它节点。 ##
## 另外它还会将您的节点信息告知与其相连接的其它节点,这样它 ##
## 们也可以连接到您的节点。 ##
## ##
## connect 在您的节点“连接”到它的时候并不会做上述工作。仅 ##
## 它会与您连接,而其它节点不会。 ##
## ##
## 因此如果您位于防火墙后,或者因为其它原因无法找到节点,则 ##
## 使用“addnode”添加一些节点。 ##
## ##
## 如果您想保证隐私,使用“connect”连接到那些您可以“信任” ##
## 的节点。 ##
## ##
## 如果您在一个局域网内运行了多个节点,您不需要让它们建立许多 ##
## 连接。您只需要使用“connect”让它们统一连接到一个已端口转 ##
## 发并拥有多个连接的节点。 ##

# Use as many addnode= settings as you like to connect to specific peers
#addnode=69.164.218.197
#addnode=10.0.0.2:8333

# Alternatively use as many connect= settings as you like to connect ONLY to specific peers
#connect=69.164.218.197
#connect=10.0.0.1:8333

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

# Port on which to listen for connections (default: 8333, testnet: 18333, regtest: 18444)
#port=

# Maximum number of inbound+outbound connections.

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

# server=1 tells Bitcoin-Qt and bitcoind to accept JSON-RPC commands
#server=0

# Bind to given address to listen for JSON-RPC connections.
# Refer to the manpage or bitcoind -help for further details.
#rpcbind=<addr>

# 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 config option `rpcauth` can be added to server startup argument. It is set at initialization time
# using the output from the script in share/rpcauth/rpcauth.py after providing a username:
#
# ./share/rpcauth/rpcauth.py alice
# String to be appended to bitcoin.conf:
# rpcauth=alice:f7efda5c189b999524f151318c0c86$d5b51b3beffbc02b724e5d095828e0bc8b2456e9ac8757ae3211a5d9b16a22ae
# Your password:
# DONT_USE_THIS_YOU_WILL_GET_ROBBED_8ak1gI25KFTvjovL3gAM967mies3E=
#
# On client-side, you add the normal user/password pair to send commands:
#rpcuser=alice
#rpcpassword=DONT_USE_THIS_YOU_WILL_GET_ROBBED_8ak1gI25KFTvjovL3gAM967mies3E=
#
# You can even add multiple entries of these to the server conf file, and client can use any of them:
# rpcauth=bob:b2dd077cb54591a2f3139e69a897ac$4e71f08d48b4347cf8eff3815c0e25ae2e9a4340474079f55705f40574f4ec99

# How many seconds bitcoin 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 tells Bitcoin-Qt to accept JSON-RPC commands.
# it is also read by bitcoind to determine if RPC should be enabled
#rpcallowip=10.1.1.34/255.255.255.0
#rpcallowip=1.2.3.4/24
#rpcallowip=2001:db8:85a3:0:0:8a2e:370:7334/96

# 在如下端口监听 RPC 连接
# rpcport=8332

# 您可以通过如下设置使用 Bitcoin 或 bitcoind 来发送命令到一个在
# 其它主机远程运行的 Bitcoin/bitcoind 客户端
# rpcconnect=127.0.0.1

# Wallet options

# Specify where to find wallet, lockfile and logs. If not present, those files will be
# created as new.
#wallet=</path/to/dir>

# Create transactions that have enough fees so they are likely to begin confirmation within n blocks (default: 6).
# This setting is over-ridden by the -paytxfee option.
#txconfirmtarget=n

# Pay a transaction fee every time you send bitcoins.
#paytxfee=0.000x

# Miscellaneous options

# Pre-generate this many public/private key pairs, so wallet backups will be valid for
# both prior transactions and several dozen future transactions.
#keypool=100

# Enable pruning to reduce storage requirements by deleting old blocks.
# This mode is incompatible with -txindex and -rescan.
# 0 = default (no pruning).
# 1 = allows manual pruning via RPC.
# >=550 = target to stay under in MiB.
#prune=550

# User interface options

# Start Bitcoin minimized
#min=1

# Minimize to the system tray
#minimizetotray=1

# [Sections]
# Most options apply to mainnet, testnet and regtest.
# If you want to confine an option to just one network, you should add it in the
# relevant section below.
# EXCEPTIONS: The options addnode, connect, port, bind, rpcport, rpcbind and wallet
# only apply to mainnet unless they appear in the appropriate section below.

# Options only for mainnet
[main]

# Options only for testnet
[test]

# Options only for regtest
[regtest]

然后我们只要调用bitcoind -datadir=数据目录,就可以进行bitcoind的启动了。

我个人的C盘空间吃紧,所以数据目录我就设成了f盘,启动命令如下:

bitcoind -datadir='/mnt/f/bitcoin_data/'  -conf='/home/lsm/bitcoin/bitcoin.conf'
