远程部署 Steem 机器人, ubuntu 18.04下用Anaconda 安装python 和 beem

前几天,本地开发 steem 机器人,在 MacOS上用 <Anaconda 安装 beem,开发 python版本的 steem 机器人>

今天,购买了远程服务器,安装好ubuntu18.04的环境,再用Anaconda 安装python 和 beem.

Anaconda的好处是,跨平台管理 python开发环境, 不管你是windows开发者,还是linux/mac的开发者,基本操作都差不多.

ubuntu 安装 Anaconda3

beem工具的运行环境要求 Anaconda3 (Python3) ,如果 Anaconda 官方下载太慢,可用清华大学镜像:

$ cd ~
$ sudo apt-get remove python3 python3-dev python3-pip
$ wget https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-2019.07-Linux-x86_64.sh
$ chmod a+x Anaconda3-2019.07-Linux-x86_64.sh
$ sh ./Anaconda3-2019.07-Linux-x86_64.sh
$ source ~/.bashrc
$ conda activate
(base) ~$ python -V
(base) ~$ pip -V 
(base) ~$ sudo apt install libffi-dev libssl-dev  

退出Anaconda3环境:(base) ~$ conda deactivate

后续操作,基本跟 MacOS 上一致.

Anaconda3 安装 beem

$ cd ~
$ conda activate
(base) ~$ conda config --add channels conda-forge 
(base) ~$ conda install beem 
(base) ~$ conda install cryptography  

使用 beempy

使用最快的节点:$ beempy pingnode --sort
创建本地钱包密码:$ beempy createwallet
查看钱包信息:$ $ beempy walletinfo

修改本地钱包密码:$ beempy changewalletpassphrase
添加steem账号:$ beempy addkey
删除steem账号:beempy delkey [OPTIONS] public_key
查看钱包内的steem账号:$ beempy listaccounts

from beem.blockchain import Blockchain
from beem.utils import parse_time

if __name__ == "__main__":
    blockchain = Blockchain()
    for vote in blockchain.stream(opNames=["comment"]):
        print(vote)

执行程序:python demo.py
