搭建electrumx regtest
参考 https://electrumx.readthedocs.io/en/latest/HOWTO.html
在ubuntu-20.04-live-server-amd64 下，系统自带python 3.8
用pip3 install aiohttp， pylru， pylru 库
下面假定操作系统用户是cute
安装daemontools
http://cr.yp.to/daemontools/install.html
获取electrumx代码
git clone https://github.com/kyuupichan/electrumx.git
cd electrumx
python3 setup.py 创建db目录
cd ~
mkdir ~/electrumx_db创建服务
mkdir ~/service
mkdir -p ~/scripts/electrumx
cp -R /path/to/repo/electrumx/contrib/daemontools/* ~/scripts/electrumx上面cp命令比electrumx文档在daemontools后多了 /*
修改evn参数
cd ~/scripts/electrumx/env下面就是配置文件和内容，环境参数具体含义 https://electrumx.readthedocs.io/en/latest/environment.html

cute生成ssl文件,openssl中间有需要填写内容，可以直接回车
cd ~/scripts/electrumx
openssl genrsa -out server.key 2048
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 1825 -in server.csr -signkey server.key -out server.crt启动服务
cd ~/service
ln -s ~/scripts/electrumx electrumx
svscan ~/service & disown查看日志
tail -F /path/to/log/dir/current | tai64nlocal启动electrum regtest钱包，用https://download.electrum.org/3.3.8/Electrum-3.3.8.tar.gz 时，修改servers_regtest.json
cd Electrum-3.3.8
./run_electrum daemon --regtest start注意：bitcoind启动时要加-reindex -txindex参数。
