GitHub安装说明
https://github.com/EOSIO/eos/tree/dawn-2.x
macOS 下安装
- 升级系统到macOS High Sierra。
- 安装Xcode最新版本。
- 从github克隆代码，执行安装脚本。
git clone https://github.com/eosio/eos --recursive
# 本文发布时master不稳定，切换到dawn-2.x分支
git checkout dawn-2.x
cd eos
./build.sh darwin
# 启动eosd sever进程，首次执行会自动停止，产生data-dir/config.ini文件
./build/eosd/eosd
# 修改config.ini文件，见下方问题区。
# 启动eosd
./build/eosd/eosd
# 启动eosc，命令行工具eosc查看eosd的信息
./build/eosc/eosc get info
注意：版本问题。

安装过程中遇到的问题
说在前面
我最早是从master分支直接安装的，中间遇到了一些问题，知道最后启动服务发现没有产生区块，才改成稳定的dawn-2.x版本。所以，如果你直接从dawn-2.x版本开始安装的话，下面的一些问题不一定会遇到。
磁盘空间
磁盘空间要求至少100GB，否则报错。先修改脚本scripts/eosio/build/darwin.sh，先绕过去限制。
# if [ $DISK_AVAIL -lt 100 ]; then
if [ $DISK_AVAIL -lt 10 ]; then # 修改为10GB
printf "\tYou must have at least 100GB of available storage to install EOSIO.\n"
printf "\tExiting now.\n"
exit 1
fi
autoreconf -i 报错
Usage: autoreconf [-f] [-h] [--help] [-m dir] [--macrodir=dir]
[-l dir] [--localdir=dir] [--force] [--verbose] [--version]
解决：更新版本autoconf 到2.69， 原本PATH里有指向低版本autoconf 2.10的路径，删掉。
libtoolize 报错
Can't exec "libtoolize": No such file or directory at /usr/local/share/autoconf/Autom4te/FileUtils.pm line 345, <GEN3> line 5.
autoreconf: failed to run libtoolize: No such file or directory
autoreconf: libtoolize is needed because this package uses Libtool
Error running autogen
解决：
要用glibtool，参考
https://stackoverflow.com/questions/15448582/installed-libtool-but-libtoolize-not-found
http://blog.csdn.net/diandianxiyu_geek/article/details/56667415
解法：
#添加PATH /usr/local/Cellar/libtool/2.4.6_1/bin
export PATH=/usr/local/Cellar/libtool/2.4.6_1/bin:$PATH
brew install boost double-conversion gflags glog libevent
sudo ln -s /usr/local/bin/glibtoolize /usr/local/bin/libtoolize
openssl问题
在编译的时候遇到openssl版本问题。报错如下：
CMake Error at /usr/local/Cellar/cmake/3.7.2/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:138 (message):
Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the
system variable OPENSSL_ROOT_DIR (missing: OPENSSL_LIBRARIES
OPENSSL_INCLUDE_DIR)
原因在于安装脚本里为Darwin指定了openssl的路径如下，默认版本为1.1：
if [ $ARCH == "Darwin" ]; then
OPENSSL_ROOT_DIR=/usr/local/opt/openssl@1.1
OPENSSL_LIBRARIES=/usr/local/opt/openssl@1.1/lib
但是系统里安装的是1.0.2版本。
eos ansen$ ls -lh /usr/local/opt/openssl@1.0
lrwxr-xr-x 1 ansen admin 24B 2 19 00:47 /usr/local/opt/openssl@1.0 -> ../Cellar/openssl/1.0.2n
用brew安装openssl@1.1后，编译还是有问题，说找不到symbol，google搜了一圈，没找到解决办法。

clang-4.0: error: linker command failed with exit code 1 (use -v to see invocation)
解决： 修改安装脚本，使用1.0版本，编译就成功了。
if [ $ARCH == "Darwin" ]; then
OPENSSL_ROOT_DIR=/usr/local/opt/openssl@1.0
OPENSSL_LIBRARIES=/usr/local/opt/openssl@1.0/lib
安装成功，显示如下：

修改config.ini
在自动生成的config.ini的基础上修改下面这些配置项。 genesis就是eos根目录的genesis.json。
# Load the testnet genesis state, which creates some initial block producers with the default key
genesis-json = /path/to/eos/source/genesis.json
# Enable production on a stale chain, since a single-node test chain is pretty much always stale
enable-stale-production = true
# Enable block production with the testnet producers
producer-name = inita
producer-name = initb
producer-name = initc
producer-name = initd
producer-name = inite
producer-name = initf
producer-name = initg
producer-name = inith
producer-name = initi
producer-name = initj
producer-name = initk
producer-name = initl
producer-name = initm
producer-name = initn
producer-name = inito
producer-name = initp
producer-name = initq
producer-name = initr
producer-name = inits
producer-name = initt
producer-name = initu
# Load the block producer plugin, so you can produce blocks
plugin = eosio::producer_plugin
# Wallet plugin
plugin = eosio::wallet_api_plugin
# As well as API and HTTP plugins
plugin = eosio::chain_api_plugin
plugin = eosio::http_plugin
代码分支版本问题
最早是从master开始编译的，解决了上面的问题后，最后运行起来确发现没有产生区块。

看到有篇文章里写到，master版本不稳定，建议切换会dawn-2.x版本。
dawn-2.x版本执行build/eosd/eosd。然后会有区块产生。
