Bitcoind - What is rpcuser? - Bitcoin Stack Exchange Bitcoin.conf rpcuser rpcpassword

Содержание статьи

From Bitcoin Wiki

There are two variations of the original bitcoin program available; one with a graphical user interface (usually referred to as just “Bitcoin”), and a 'headless' version (called bitcoind). They are completely compatible with each other, and take the same command-line arguments, read the same configuration file, and read and write the same data files. You can run one copy of either Bitcoin or bitcoind on your system at a time (if you accidently try to launch another, the copy will let you know that Bitcoin or bitcoind is already running and will exit).

Linux Quickstart

The simplest way to start from scratch with the command line client, automatically syncing blockchain and creating a wallet, is to just run this command (without arguments) from the directory containing your bitcoind binary:

 ./bitcoind

To run with the standard GUI interface:

 ./bitcoin-qt

Command-line arguments

These commands are accurate as of Bitcoin Core version v0.14.0.

Command Description
-? Print this help message and exit
-version Print version and exit
-alertnotify= Execute command when a relevant alert is received or we see a really long fork (%s in cmd is replaced by message)
-blocknotify= Execute command when the best block changes (%s in cmd is replaced by block hash)
-assumevalid= If this block is in the chain assume that it and its ancestors are valid and potentially skip their script verification (0 to verify all, default: 00000000000000000013176bf8d7dfeab4e1db31dc93bc311b436e82ab226b90, testnet: 00000000000128796ee387cf110ccb9d2f36cffaf7f73079c995377c65ac0dcc)
-conf= Specify configuration file (default: bitcoin.conf)
-datadir= Specify data directory
-dbcache= Set database cache size in megabytes (4 to 16384, default: 300)
-loadblock= Imports blocks from external blk000??.dat file on startup

This allows the pruneblockchain RPC to be called to delete specific blocks, and enables automatic pruning of old blocks if a target size in MiB is provided. This mode is incompatible with -txindex and -rescan. Warning: Reverting this setting requires re-downloading the entire blockchain. (default: 0 = disable pruning blocks, 1 = allow manual pruning via RPC, >550 = automatically prune block files to stay under the specified target size in MiB)

Bitcoin.conf Configuration File

All command-line options (except for -conf) may be specified in a configuration file, and all configuration file options may also be specified on the command line. Command-line options override values set in the configuration file.

The configuration file is a list of setting=value pairs, one per line, with optional comments starting with the '#' character.

The configuration file is not automatically created; you can create it using your favorite plain-text editor. A user-friendly configuration file generator is available here. By default, Bitcoin (or bitcoind) will look for a file named 'bitcoin.conf' in the bitcoin data directory, but both the data directory and the configuration file path may be changed using the -datadir and -conf command-line arguments.

Operating System Default bitcoin datadir Typical path to configuration file
Windows  %APPDATA%\Bitcoin\ C:\Users\username\AppData\Roaming\Bitcoin\bitcoin.conf
Linux $HOME/.bitcoin/ /home/username/.bitcoin/bitcoin.conf
Mac OSX $HOME/Library/Application Support/Bitcoin/ /Users/username/Library/Application Support/Bitcoin/bitcoin.conf

Note: if running Bitcoin in testnet mode, the sub-folder "testnet" will be appended to the data directory automatically.

## 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. ##

Idea: Bitcoin.conf created by default · Issue #3902 .

Bitcoin allows a user to create their own configuration file which specifies runtime options to use during each program start. Options that can be added to a configuration file are most of the options listed in the Command Line Options reference for Bitcoin.

A configuration file is a standard text file you create in the Bitcoin data directory. This file is optional, and is not created by Bitcoin. The file must be named bitcoin.conf

bitcoin.conf template

This is an example bitcoin.conf file. You must edit it before use – specifically, you must change the rpcpassword option to a unique password of your own creation.

Example of OpenSSL settings used when *rpcssl*='1': rpcsslciphers='TLSv1+HIGH:!SSLv2:!aNULL:!eNULL:!AH:!3DES:@STRENGTH' rpcsslcertificatechainfile='server.cert' rpcsslprivatekeyfile='server.pem' MISCELLANEOUS OPTIONS gen=['0'|'1'] Enable or disable attempt to generate bitcoins. 4way=['0'|'1'] Enable or disable use SSE instructions to try to generate bitcoins faster. keypool='100' Pre-generate this many public/private key pairs, so wallet backups will be valid for both prior transactions and several dozen future transactions. paytxfee='0.00' Pay an optional transaction fee every time you send bitcoins. Transactions with fees are more likely than free transactions to be included in generated blocks, so may be validated sooner. allowreceivebyip='1' Allow direct connections for the 'pay via IP address' feature. USER INTERFACE OPTIONS min=['0'|'1'] Enable or disable start bitcoind minimized. minimizetotray=['0'|'1'] Enable or disable minimize to the system tray.

Bitcoin Gold Testnet Participation Manual

bitcoin.conf的配置项和自己写bat,配置启动项的配置都一样。

例如bitcoin-qt-testnet.bat内容如下

bitcoin-qt.exe -testnet -datadir=C:\BitcoinData-Testnet -conf=bitcoin.conf -server -rpcuser=username-rpcpassword=password -rpcport=18332 -rpcallowip=* -rpcssl -txindex -lang=en_US

如下是bitcoin.conf包含的配置项
