1 硬件软件环境
当前使用Mac OS High Sierra
EOS版本使用最新的
2 编译设置开发环境
2.1 下载EOS源码
git clone https://github.com/eosio/eos --recursive
PS:一定要加上recursive 加载所有子模块
2.2 编译源码生成可执行文件
进入刚下载的目录，输入执行指令：
./eosio_build.sh
中途如有以下提示，输入1选择安装
1.png
安装完成的提示信息：
success.png
EOS的可执行程序/eos/build/programs这个路径下面
PS:下载时间有点久，对网络要求比较高
2.3 建立区块链节点
切换到目录eos/build/programs/nodeos下面，然后执行如下命令。
./nodeos命令可附带 --data-dir 节点文件夹名字 参数，默认文件夹为nodeos。
./nodeos
修改config.ini文件，路径：
/Users/username/Library/Application Support/eosio/nodeos/config
我的文件内容如下：
