ubuntu 16.04编译steem并运行cli_wallet

刚接触steem的时候设想在树莓派上运行full node，因为白皮书上说比特币的挖矿方式太浪费电，环境不友好，想当然的以为此法可行。经过一周在一台4核，4G内存，60GSSD虚拟机上尝试运行steemd，同步到区块5,200,000后基本停滞下来。 @oflyhigh说树莓派上同步完需要1亿年。

虚拟机本地测试没有考虑太多安全性相关的问题，直接用root进行以以下脚本的操作。编译的脚本来自steemit官方github仓库，一开始按照steem.center上的How to obtain the STEEM client 编译Boost浪费了不少时间。如果你的虚拟机内存较小，编译会出错，需要增加swap。

dd if=/dev/zero of=/var/swap.img bs=1024k count=4096
mkswap /var/swap.img
swapon /var/swap.img

git clone https://github.com/steemit/steem
cd steem
git submodule update --init --recursive
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j$(nproc) steemd
make -j$(nproc) cli_wallet
# optional
make install  # defaults to /usr/local

swapoff /var/swap.img
rm -rf /var/swap.img

以上脚本一次性编译生成steemd和cli_wallet。

运行cli_wallet

@abit说运行full node需要80G内存，low memory node需要8G内存，暂时放弃了自己运行full node，因为现在的目标是理解Steem的经济系统以及如何操作blockchain api。steem是个有爱的社区，好多witness都开放了full node，经过多次连接后，我觉得gtg的那个节点稳定性最好，运行以下这行命令就可以开始steem的blockchain api之旅了：cli_wallet -s wss://gtg.steem.house:8090

可以再试试 info help这两个命令
