electrumx搭建流程

一、環境:ubuntu1604  python3.7

1、python3.7安裝

# 使用pip3.7安裝依賴包報錯：

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.


解決這個坑:

# 先刪除原來安裝的python3.7，注意一定要重裝

rm -rf /usr/local/python3

安裝下面依賴,不安裝這個會有坑:

apt install libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev libtk8.5 libgdm-dev libdb4o-cil-dev libpcap-dev


# 重新安裝python3.7.1

wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tgz

tar -xzvf Python-3.7.1.tgz

./configure --prefix=/usr/local/python3

make && make install


# 報錯：ModuleNotFoundError: No module named '_ctypes'

# 解決方法如下:

sudo apt-get update

sudo apt-get upgrade

sudo apt-get dist-upgrade

sudo apt-get install build-essential python-dev python-setuptools python-pip python-smbus

sudo apt-get install build-essential libncursesw5-dev libgdbm-dev libc6-dev

sudo apt-get install zlib1g-dev libsqlite3-dev tk-dev

sudo apt-get install libssl-dev openssl

sudo apt-get install libffi-dev


#重新編譯

make && make install


# 添加環境變量：

export PATH=$PATH:/usr/local/python3/bin:/usr/local/python3/lib


# 建立pip3.7的軟鏈接

rm /usr/bin/pip

rm /usr/local/bin/pip

ln -s /usr/local/python3/bin/pip3.7 /usr/bin/pip

ln -s /usr/local/python3/bin/pip3.7 /usr/local/bin/pip


# 建立python3的軟鏈接

rm /usr/bin/python3

ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3

2、安裝 electrumx-1.14.0 的包

pip install aiohttp

pip install aiorpcX

pip install ecdsa

pip install plyvel

pip install pycodestyle

pip install pylru

pip install python-rocksdb

pip install pytest-asyncio

pip install pytest-cov

pip install Sphinx

pip install tribus-hash

pip install blake256

pip install scrypt

pip install x11_hash

pip install git+https://github.com/bitcoinplusorg/x13-hash

pip install xevan_hash

pip install quark_hash

pip install groestlcoin_hash

pip install neoscrypt

pip install x16r_hash

pip install pycryptodomex

pip install git+https://github.com/Electra-project/nist5_hash

pip install git+https://github.com/RitoProject/x21s_hash

pip install git+https://github.com/traysi/x16rv2_hash

pip install bell-yespower

pip install cpupower

二、克隆electrumx代碼

git clone https://github.com/kyuupichan/electrumx.git

#checkout 1.14.0版本
cd electrumx
git checkout 1.14.0

三、修改electrumx代碼,修改/electrumx/server/session.py文件的三個地方

# 通過地址獲取餘額

async def scripthash_get_balance(self, scripthash):

    '''Return the confirmed and unconfirmed balance of a scripthash.'''

  - hashX = address_to_hashX(scripthash)

  + coin = self.env.coin

  + hashX = coin.address_to_hashX(scripthash)

    return await self.get_balance(hashX)


# 通過地址獲取交易記錄

async def scripthash_get_history(self, scripthash):

    '''Return the confirmed and unconfirmed history of a scripthash.'''

  - hashX = scripthash_to_hashX(scripthash)

  + coin = self.env.coin

  + hashX = coin.address_to_hashX(scripthash)

    return await self.confirmed_and_unconfirmed_history(hashX)


#通過地址獲取utxo

async def scripthash_listunspent(self, scripthash):

    '''Return the list of UTXOs of a scripthash.'''

    hashX = scripthash_to_hashX(scripthash)

  + coin = self.env.coin

  + hashX = coin.address_to_hashX(scripthash)

    return await self.hashX_listunspent(hashX)

四、編譯electrumx代碼

cd electrumx

python setup.py build

python setup.py install   #也可以不安裝

五、配置electrumx的運行環境變量並啓動,可以寫到一個.sh文件中,不同的幣種這個配置是不同的

cat run_electrumx_server_btc.sh

#!/bin/bash

export COIN=BitcoinSegwit   # 幣名

export DAEMON_URL=http://user:[email protected]:8332/  #節點rpc 用戶密碼 ip 端口

export NET=mainnet   #主網還是測試網

export CACHE_MB=1200   #同步緩存大小

export DB_DIRECTORY=/data/electrumx_data/btc      #數據存儲位置

export SSL_CERTFILE=/etc/electrumx/certfile.crt   #SSL通信證書位置

export SSL_KEYFILE=/etc/electrumx/keyfile.key     #SSL通信密鑰位置

export BANNER_FILE=/etc/electrumx/banner

export DONATION_ADDRESS=your-donation-address

export ALLOW_ROOT=true     #是否允許root賬戶

export SERVICES=tcp://0.0.0.0:50001,rpc://127.0.0.1:8000   //tcp和rpc監聽端口


nohup python electrumx_server_btc &   #後臺啓動

六、其他問題解決,安裝和使用pip過程中存着一些暗坑,解決方法

# 1、問題: pip安裝報錯:

prompt-toolkit 1.0.15 has requirement six>=1.9.0, but you’ll have six 1.4.1 which is incompatible.

# 解決:

pip install six --user -U

pip install ipython --user -U


# 2、問題: pip升級失敗

# 解決: 

python -m pip install -U --upgrade pip --user


# 3、ubuntu 安裝python3.7 以及安裝pip3 出現Command '('lsb_release', '-a')' returned non-zero exit status 1問題解決

# 解決: 

sudo rm /usr/bin/lsb_release


# 4、dash同步過程中報錯:struct.error: 'H' format requires 0 <= number <= 65535

# 解決:

執行壓縮歷史記錄腳本:electrumx_compact_history
