GitHub安装说明

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, line 5.

autoreconf: failed to run libtoolize: No such file or directory

autoreconf: libtoolize is needed because this package uses Libtool

Error running autogen

#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。

ld: symbol(s) not found for architecture x86_64

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。

1046000ms thread-0 producer_plugin.cpp:227 block_production_loo ] Not producing block because it isn't my turn, its eosio

1046500ms thread-0 producer_plugin.cpp:227 block_production_loo ] Not producing block because it isn't my turn, its eosio

1047000ms thread-0 producer_plugin.cpp:227 block_production_loo ] Not producing block because it isn't my turn, its eosio

1047500ms thread-0 producer_plugin.cpp:227 block_production_loo ] Not producing block because it isn't my turn, its eosio

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。

eosc执行
