自己早已习惯于在steemit上面发文章，也习惯于和steemit上认识的朋友交流，而且前期投入过一万RMB买了STEEM（今天来看也算是翻倍了，什么时候价格能到15元再买点），怎么也该更深入的研究一下它！
安装
下载steem源代码
按照build.md进行mac下编译，官方是建议用docker进行安装上布署，不过bitshares我都各种设置编译过了，steem基于同样的graphene，应该难度不会太大吧！
由于我机器上xcode、brew等都已安装正常，如果你没有请查看官方文档或按以下：
sudo xcodebuild -license accept
安装Homebrew方法，[https://brew.sh/](https://brew.sh/)
初始化：
brew doctor
brew update
安装依赖库：
brew install \
autoconf \
automake \
cmake \
git \
boost160 \
libtool \
openssl \
snappy \
zlib \
python3
pip3 install --user jinja2
编译：
export OPENSSL_ROOT_DIR=$(brew --prefix)/Cellar/openssl/1.0.2h_1/
export BOOST_ROOT=$(brew --prefix)/Cellar/boost@1.60/1.60.0/
export SNAPPY_LIBRARIES=$(brew --prefix)/Cellar/snappy/1.1.7_1/lib/
export SNAPPY_INCLUDE_DIR=$(brew --prefix)/Cellar/snappy/1.1.7_1/include/
export ZLIB_LIBRARIES=$(brew --prefix)/Cellar/zlib/1.2.11/lib/
git checkout stable
git submodule update --init --recursive
mkdir build && cd build
cmake -DBOOST_ROOT="$BOOST_ROOT" -DCMAKE_BUILD_TYPE=Release ..
make -j$(sysctl -n hw.logicalcpu)
但是make时会出错：
[ 22%] Building CXX object libraries/fc/CMakeFiles/fc.dir/src/crypto/_digest_common.cpp.o

openssl出现问题，重新安装一下openssl看看：
(env3) Chaim:build Chaim$ brew reinstall openssl
==> Reinstalling openssl
==> Downloading https://homebrew.bintray.com/bottles/openssl-1.0.2o_1.high_sierra.bottle.tar.gz
######################################################################## 100.0%
==> Pouring openssl-1.0.2o_1.high_sierra.bottle.tar.gz
==> Caveats
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
/usr/local/etc/openssl/certs
and run
/usr/local/opt/openssl/bin/c_rehash
This formula is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.
If you need to have this software first in your PATH run:
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
For compilers to find this software you may need to set:
LDFLAGS: -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include
For pkg-config to find this software you may need to set:
PKG_CONFIG_PATH: /usr/local/opt/openssl/lib/pkgconfig
==> Summary
�� /usr/local/Cellar/openssl/1.0.2o_1: 1,791 files, 12.3MB
发现openssl安装的目录是1.0.2o_1，而不是export的目录1.0.2h_1，重新export openssl路径：
(env3) Chaim:build Chaim$ export OPENSSL_ROOT_DIR=$(brew --prefix)/Cellar/openssl/1.0.2o_1/
继续执行make还是出同样错误！
我们看到安装openssl时提示编译时应该加上lib目录和include目录，找到steem目录下CMakeLists.txt，加入以下语句：
include_directories(/usr/local/Cellar/openssl/1.0.2o_1/include)
link_directories("/usr/local/Cellar/openssl/1.0.2o_1/lib")
重新cmake和make，编译成功！
运行
steemd
进入steemd目录，运行steemd，会提示增加配置文件：
(env3) Chaim:witness_node_data_dir Chaim$ pwd
/Users/Chaim/Documents/workspace/steem/build/programs/steemd/witness_node_data_dir
(env3) Chaim:steemd Chaim$ ./steemd

1329234ms th_a witness_plugin.cpp:545 plugin_startup ] No witnesses configured! Please add witness names and private keys to configuration.
这样会在steemd目录下生成 目录，并且里面有config.ini文件，修改增加以下项：
seed-node = 52.38.66.234:2001
seed-node = 52.37.169.52:2001
seed-node = 52.26.78.244:2001

seed-node = steemd.pharesim.me:2001
seed-node = seed.steemed.net:2001
seed-node = steem.clawmap.com:2001
seed-node = seed.steemwitness.com:2001
seed-node = steem-seed1.abit-more.com:2001
增加rpc-endpoint
rpc-endpoint = 127.0.0.1:8090
重新回steemd目录，启动steemd，这样就能同步区块了：
(env3) Chaim:steemd Chaim$ ./steemd

很熟悉的命令操作了，和bitshares一模一样！
更多操作等我先研究下steem开发者的内容...
