大体步骤按https://github.com/EOSIO/eos/wiki/Local-Environment#2-building-eosio 来
拉取仓库
$ git clone https://github.com/EOSIO/eos --recursive
注意：带上参数--recursive，如果没有带上参数，clone完应该执行下面的命令（如果clone时已经带上参数，下面的命令请忽略）:
$ git submodule update --init --recursive
编译eos
$ cd eos
$ ./eosio_build.sh
编译过程耗时比较长，耐心等待一下，注意网络不能中断
执行完上面的编译过程，检查eos文件夹下是否新创建了一个 build目录，有该目录说明编译通过了,接着执行下面的步骤
$ /usr/local/bin/mongod -f /usr/local/etc/mongod.conf &
$ cd build
测试是否编译通过，不报错说明没问题，报错的话检查前面的步骤是否有问题
$ make test
接下来执行下面的命令,先进入到build目录
$ cd build
$ sudo make install
出矿
上面没问题的话，继续往下走，我们启动链节点并出矿
$ cd build/programs/nodeos
$ ./nodeos -e -p eosio --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --resync-blockchain
说明一下参数：--resync-blockchain
由于在启动节点时报错：
/xxx/Desktop/eos_demo/eos/libraries/chainbase/src/chainbase.cpp(106): Throw in function chainbase::database::database(const bfs::path &, chainbase::database::open_flags, uint64_t)
Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error> >
std::exception::what: database dirty flag set (likely due to unclean shutdown) replay or resync required
在issue里面找到答案，需要加上--resync-blockchain参数
接下来就是出矿了：
