参考：https://github.com/EOSIO/eos/wiki/Local-Environment#2-building-eosio
安装环境：ubuntu 16.04
下载代码：
git clone https://github.com/EOSIO/eos--recursive
时间有点长
完成之后如下提示：
编译：
要求：
Centos 7 或 ubuntu 16.04（官网推荐ubuntu 16.10）以上
8G 内存， 20G硬盘
// 编译过程比较漫长，由于每台机器的环境不一样，以下出现的问题不一定会出现
cd eos
./eosio_build.sh
若软硬件达不到要求执行编译脚本会提示：

原因：下载MongoDB超时，由于网络原因无法从github.com下载
将mongo-c-driver-1.9.3.tar.gz 放到 /tmp，将mongo-3.6.3.tar.gz放到 /opt下
Vim eos/scripts/eosio_build_ubuntu.sh
将以下脚本注解
// 下载mongo-c-driver-1.9.3.tar.gz脚本

继续执行编译脚本

出现LLVM无法下载问题：
Checkingfor LLVM with WASM support.
InstallingLLVM & WASM
fatal: destination path 'llvm' alreadyexists and is not an empty directory.
Unableto clone llvm repo @ https://github.com/llvm-mirror/llvm.git.
Exitingnow.
解决办法：
cd /opt
rm -rf llvm
cd /tmp
root@DESKTOP-H6EG47U:/tmp# rm -rf llvm-compiler/
成功会有如下提示
~/opt/mongodb/bin/mongod -f ~/opt/mongodb/mongod.conf & // 这个不执行节点也可以启动
启动可以参照：
https://github.com/EOSIO/eos/wiki/Local-Environment#2-building-eosio
节点启动要启动2次，否则不能同步数据
启动节点：（注意此处的坑）
/root/eos/eos/build/programs/nodeos/nodeos -e -p eosio --plugin eosio::chain_api_plugin --plugin eosio::wallet_api_plugin --plugin eosio::history_api_plugin
//带有--plugin eosio::wallet_api_plugin参数才可以调用钱包相关RPC接口
// 而官网说要在/root/.local/share/eosio/nodeos/config/config.ini
添加：
plugin = eosio::chain_api_plugin // Enable Chain API
plugin = eosio::wallet_api_plugin // Enable Wallet API
//而经过测试添加了之后无法启动，只有将 eosio::chain_api_plugin ，eosio::wallet_api_plugin在启动节点时添加
就可以启动也可以调用钱包相关RPC接口
