## 1，摘要

**【本文目标】**
通过本文实践，能在WINDOWS操作系统搭建UBUNTU 18.04 LTS环境，并在此环境编译成功EOS v1.0.5正式发布版本。
**【前置条件】**
有学习EOS环境搭建意向，不怕折腾。
**【技术收获】**
1）搭建UBUNTU 18.04 LTS环境
2）在硬件要求不满足官方要求的环境下EOS环境编译成功
3） EOS编译过程中的踩坑排查能力

## 2，编译血泪史

EOS主网上线没有几天，从各种渠道得知EOS环境搭建比较麻烦，辉哥刚开始想绕过编译环节或者直接使用可直接使用的环境。于是，辉哥首先从赵志明老师那儿拉个一个V1.0.5的已编译成功的版本，拉到笔记本的Ubuntu虚拟机环境根本没法跑起来。
然后，辉哥想用欧阳哥哥花了好长时间搭建成功的虚拟机环境来测试操作，结果发现EOS节点运行起来后，他主机的CPU占用率为90%，他就没法工作了。
又为了省钱，不愿意购买阿里云ECS环境。最终，辉哥还是在古千峰老师和欧阳哥哥的鼓励下，下定决心把EOS环境编译成功。因为目前大部分研发人员用的是WINDOWS操作系统，那在此基础上搭建Ubuntu虚拟机成功对大部分EOS学习者来说非常有帮助。而坊间搭建EOS环境编译的步骤介绍中都非常简单，基本都不写编译失败或者踩过的坑，好像编译都是很顺利似的。作为一个热心的技术布道者，辉哥就下定决心把环境编译好，并把踩的坑和方法都贡献出来，供大家学习交流。
如果还有其他人能够在其他环境，例如Centos 7, MacOs上编译成功的，希望也可以把自己编译过程制作文档，在本文留言，让更多的人少踩坑。

辉哥把编译成功的修改脚本，下载附件放在知识星球了，需要者加入自取，加入知识星球后也可以加入VIP微信群，提供技术对接。

## 3，环境配置

**1）WINDOWS主机及操作系统**
关键信息：Windows 10 64位操作系统，8G内存，4核CPU。

![](https://img.learnblockchain.cn/2020/02/01_/366818598.jpg)

Windows 10系统环境.jpg

**分析：** 从RAM要求看是不满足7GB RAM空闲资源要求，但有方法绕过去。

**2）VmWare虚拟机**
辉哥用的是VMware 10版本，可从官网下载或者参考 [《第一课 如何在WINDOWS环境下搭建以太坊开发环境》](https://www.jianshu.com/p/683ea7d62a39) 的“1，安装VMware虚拟机”章节完成虚拟机的安装。

**3）Ubuntu资源配置**
按照EOS的要求，辉哥选择UBUNTU 18.04 LTS版本。下载官网地址为 [https://www.ubuntu.com/download/server/thank-you?country=CN&version=18.04&architecture=amd64](https://www.ubuntu.com/download/server/thank-you?country=CN&version=18.04&architecture=amd64) ，AMD架构的经安装验证没有问题的。安装和配置方法参考 [《第一课 如何在WINDOWS环境下搭建以太坊开发环境》](https://www.jianshu.com/p/683ea7d62a39) 的“2，安装Ubuntu操作系统”章节完成虚拟机的安装，建议硬盘和内存选择要尽可能大一些。

**EOSIO的安装最低配置：**

1. 7GB RAM free required
2. 20GB Disk free required
    辉哥的环境的RAM是不满足要求的，后面编译的时候注释代码绕过去，不影响编译成功。

## 4，编译历程和踩坑记录

### 4.1 【错误1】直接下载版本不可行

辉哥从EOSIO官网上 [下载V1.0.5的版本](https://github.com/EOSIO/eos/tree/v1.0.5) ，然后上传到Ubuntu虚拟机环境，运行'./eosio_build.sh'提示必须用github下载。只所以用v1.0.5版本，只是一个个人临时决定而已。

**【信息交互提示1】**

> duncanwang@duncanwang:~/work/eos-1.0.5$ ./eosio_ [build.sh](http://build.sh)

**输出：**

```
> -bash: ./eosio_build.sh: Permission denied

```

**解决方案：**

> duncanwang@duncanwang:~/work/eos-1.0.5$ chmod 755 ./eosio_ [build.sh](http://build.sh)

**【信息交互提示2】**

> duncanwang@duncanwang:~/work/eos-1.0.5$ ./eosio_ [build.sh](http://build.sh)

**输出：**

```
> This build script only works with sources cloned from git
    Please clone a new eos directory with 'git clone https://github.com/EOSIO/eos --recursive'
    See the wiki for instructions: https://github.com/EOSIO/eos/wiki

```

### 4.2 【错误2】Github下载提示连不上github

**【信息交互提示】**

> duncanwang@duncanwang:~/work$ git clone -b v1.0.5 [https://github.com/EOSIO/eos](https://github.com/EOSIO/eos) --recursive

**输出：**

```
Cloning into 'eos'...
fatal: unable to access 'https://github.com/EOSIO/eos/': Could not resolve host: github.com

```

**解决方案：**
提示表明链接不上github网站，增加了香港服务器解决。

1. 加入香港线路

> sudo vim /etc/hosts

加入以下配置后保存

> 192.30.253.113 github.com

1. 命令行增加配置

> git config --global http.sslversion tlsv1

### 4.3 【错误3】Github下载提示端口错误

**【信息交互提示】**

> duncanwang@duncanwang:~/work$ git clone [https://github.com/EOSIO/eos](https://github.com/EOSIO/eos) --recursive

```
Cloning into 'eos'...
fatal: unable to access 'https://github.com/EOSIO/eos/': Failed to connect to github.com port 443: No route to host

```

> duncanwang@duncanwang:~/work$ ping [github.com](http://github.com)

```

```

**解决方案：**
参考网上方法，运行以下命令，但是结果还是不行。

> sudo iptables -I INPUT -p tcp --dport 443 -j ACCEPT

古哥的建议是先解决linux翻墙的问题，有点小难度。辉哥就重启了一下Ubuntu虚拟机，然后重新下载，发现下载成功了。

### 4.4 【成功】版本下载成功

> duncanwang@duncanwang:~$ git clone -b v1.0.5 [https://github.com/EOSIO/eos](https://github.com/EOSIO/eos) --recursive

```

```

### 4.5 【错误4】编译提示RAM空间不足

**输入：**

> duncanwang@duncanwang:~/eos$ ./eosio_ [build.sh](http://build.sh)

**错误提示：**

```
    Beginning build version: 1.2
    Wed Jun 27 10:24:48 UTC 2018
    User: duncanwang

    Disk space total: 19G
    Disk space available: 13G
    Your system must have 7 or more Gigabytes of physical memory installed.
    Exiting now.

```

**解决方法：**
进到eos/scripts/路径，修改对应的sh文件，找到“Your system must have 7 or more Gigabytes of physical memory installed”字样，或者You must have at least %sGB of available storage to install EOSIO，将后面的exit 1命令去掉即可。

```
 if [ "${MEM_MEG}" -lt 7000 ]; then
        printf "\\tYour system must have 7 or more Gigabytes of physical memory installed.\\n"
        printf "\\tExiting now.\\n"
  ##     exit 1
    fi

```

顺道把硬盘不足的提示也注释掉，测试发现13G的空闲硬盘是可以编译成功的。

```
>   if [ "${DISK_AVAIL%.*}" -lt "${DISK_MIN}" ]; then
        printf "\\tYou must have at least %sGB of available storage to install EOSIO.\\n" "${DISK_MIN}"
        printf "\\tExiting now.\\n"
##       exit 1
    fi

```

### 4.6 【错误5】mongoDB无法下载

**编译过程中错误提示：**

```
    Boost successfully installed @ /home/duncanwang/opt/boost.

```

**分析：**
eosio_build_ubuntu.sh 查找 “Unable to download MongoDB at this time.”关键字
可知这个语句执行失败。

> --STATUS=$(curl -LO -w '%{http_code}' --connect-timeout 30 [https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.6.3.tgz](https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.6.3.tgz) )

**解决办法：**
1）本地下载2个文件“mongodb-linux-x86_64-3.6.3.tgz”和“mongo-c-driver-1.9.3.tar.gz”，上传到虚拟机的软件存放目录“/home/duncanwang/work/software”，
2）修改脚本，重新运行 `./eosio_build.sh` 即可解决。这2个下载文件可在辉哥的知识星球找到，也可以上官网下载。

```
        #STATUS=$(curl -LO -w '%{http_code}' --connect-timeout 30 https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.6.3.tgz)
        #if [ "${STATUS}" -ne 200 ]; then
        ##   printf "\\tUnable to download MongoDB at this time.\\n"
        ##   printf "\\n\\tExiting now.\\n\\n"
        ##   exit 1;
        #fi
        cp /home/duncanwang/work/software/mongodb-linux-x86_64-3.6.3.tgz "${HOME}/opt/"

##       STATUS=$(curl -LO -w '%{http_code}' --connect-timeout 30 https://github.com/mongodb/mongo-c-driver/releases/download/1.9.3/mongo-c-driver-1.9.3.tar.gz)
##       if [ "${STATUS}" -ne 200 ]; then
##           if ! rm -f "${TEMP_DIR}/mongo-c-driver-1.9.3.tar.gz"
##           then
##               printf "\\n\\tUnable to remove file %s/mongo-c-driver-1.9.3.tar.gz.\\n" "${TEMP_DIR}"
##           fi
##           printf "\\tUnable to download MongoDB C driver at this time.\\n"
##           printf "\\tExiting now.\\n\\n"
##           exit 1;
##       fi
   cp /home/duncanwang/work/software/mongo-c-driver-1.9.3.tar.gz "${TEMP_DIR}/"

```

4.7 【错误6】RPC错误
**编译过程中错误提示：**

```

fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
    Unable to clone clang repo @ https://github.com/llvm-mirror/clang.git.

fatal: The remote end hung up unexpectedly
fatal: early EOF

```

**解决方法**
提示RPC错误，古千峰反馈说，主网RPC服务不稳定。
1） 辉哥想到的方法是把需要的 `git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/llvm.git` ， `git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/clang.git` 单独执行或者从windows下载转放到Ubuntu对应目录。
编译的提示如下，还是搞不定。有大侠认为是因为我们下载的 `llvm.git` , `clang.git` 用的是最新版本的原因，没有用 release_40的版本，没有做重新尝试。

```
CMake Error at tools/clang/tools/diagtool/CMakeLists.txt:14 (target_link_libraries):
  The keyword signature for target_link_libraries has already been used with
  the target "diagtool".  All uses of target_link_libraries with a target
  must be either all-keyword or all-plain.

The uses of the keyword signature are here:

* cmake/modules/LLVM-Config.cmake:105 (target_link_libraries)
   * cmake/modules/AddLLVM.cmake:785 (target_link_libraries)

```

2）辉哥第二天早晨过来，把 `/tmp/llvm-compiler` 文件夹删除，重新编译一下，结果什么都成了。

### 4.8【成功】编译成功

完成4.7的删除文件夹重编译后，编译就成功了。

## 5\. 编译总结

EOS成功的编译总是相同的，不成功的编译各个各的不幸。这儿总结下成功的步骤，一般是及其简单的。
**1）、下载最新代码**
git clone [https://github.com/EOSIO/eos.git](https://github.com/EOSIO/eos.git) --recursive
**3）、内存限制修改**
ubuntu：eosio_build_ubuntu.sh 25行7000改成3000
**4）、编译**
./eosio_build.sh
**5）、安装命令：cd build 然后maker install**

## 6\. 【成功】私有节点运行

辉哥解决不了哪个安装测试错误的问题，就当做没有发生了。
直接输入命令启动私有节点。

> cd ~/eos/build/programs/nodeos

> ./nodeos -e -p eosio --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin

*编译过程中得到古千峰大侠和欧阳哥哥的帮助，深表感谢。技术圈要多做分享，不怕被学习，自身更容易获得成长！*

1，摘要

【本文目标】 通过本文实践，能在WINDOWS操作系统搭建UBUNTU 18.04 LTS环境，并在此环境编译成功EOS v1.0.5正式发布版本。 【前置条件】 有学习EOS环境搭建意向，不怕折腾。 【技术收获】 1）搭建UBUNTU 18.04 LTS环境 2）在硬件要求不满足官方要求的环境下EOS环境编译成功 3） EOS编译过程中的踩坑排查能力

2，编译血泪史

EOS主网上线没有几天，从各种渠道得知EOS环境搭建比较麻烦，辉哥刚开始想绕过编译环节或者直接使用可直接使用的环境。于是，辉哥首先从赵志明老师那儿拉个一个V1.0.5的已编译成功的版本，拉到笔记本的Ubuntu虚拟机环境根本没法跑起来。然后，辉哥想用欧阳哥哥花了好长时间搭建成功的虚拟机环境来测试操作，结果发现EOS节点运行起来后，他主机的CPU占用率为90%，他就没法工作了。又为了省钱，不愿意购买阿里云ECS环境。最终，辉哥还是在古千峰老师和欧阳哥哥的鼓励下，下定决心把EOS环境编译成功。因为目前大部分研发人员用的是WINDOWS操作系统，那在此基础上搭建Ubuntu虚拟机成功对大部分EOS学习者来说非常有帮助。而坊间搭建EOS环境编译的步骤介绍中都非常简单，基本都不写编译失败或者踩过的坑，好像编译都是很顺利似的。作为一个热心的技术布道者，辉哥就下定决心把环境编译好，并把踩的坑和方法都贡献出来，供大家学习交流。如果还有其他人能够在其他环境，例如Centos 7, MacOs上编译成功的，希望也可以把自己编译过程制作文档，在本文留言，让更多的人少踩坑。

辉哥把编译成功的修改脚本，下载附件放在知识星球了，需要者加入自取，加入知识星球后也可以加入VIP微信群，提供技术对接。

3，环境配置

1）WINDOWS主机及操作系统 关键信息：Windows 10 64位操作系统，8G内存，4核CPU。

Windows 10系统环境.jpg

分析： 从RAM要求看是不满足7GB RAM空闲资源要求，但有方法绕过去。

2）VmWare虚拟机 辉哥用的是VMware 10版本，可从官网下载或者参考《第一课如何在WINDOWS环境下搭建以太坊开发环境》的“1，安装VMware虚拟机”章节完成虚拟机的安装。

3）Ubuntu资源配置 按照EOS的要求，辉哥选择UBUNTU 18.04 LTS版本。下载官网地址为 https://www.ubuntu.com/download/server/thank-you?country=CN&version=18.04&architecture=amd64 ，AMD架构的经安装验证没有问题的。安装和配置方法参考《第一课如何在WINDOWS环境下搭建以太坊开发环境》的“2，安装Ubuntu操作系统”章节完成虚拟机的安装，建议硬盘和内存选择要尽可能大一些。

EOSIO的安装最低配置：

7GB RAM free required
20GB Disk free required 辉哥的环境的RAM是不满足要求的，后面编译的时候注释代码绕过去，不影响编译成功。

4，编译历程和踩坑记录

4.1 【错误1】直接下载版本不可行

辉哥从EOSIO官网上下载V1.0.5的版本，然后上传到Ubuntu虚拟机环境，运行'./eosio_build.sh'提示必须用github下载。只所以用v1.0.5版本，只是一个个人临时决定而已。

【信息交互提示1】

duncanwang@duncanwang:~/work/eos-1.0.5$ ./eosio_ build.sh

输出：

> -bash: ./eosio_build.sh: Permission denied

解决方案：

duncanwang@duncanwang:~/work/eos-1.0.5$ chmod 755 ./eosio_ build.sh

【信息交互提示2】

duncanwang@duncanwang:~/work/eos-1.0.5$ ./eosio_ build.sh

输出：

> This build script only works with sources cloned from git
    Please clone a new eos directory with 'git clone https://github.com/EOSIO/eos --recursive'
    See the wiki for instructions: https://github.com/EOSIO/eos/wiki

4.2 【错误2】Github下载提示连不上github

【信息交互提示】

duncanwang@duncanwang:~/work$ git clone -b v1.0.5 https://github.com/EOSIO/eos --recursive

输出：

Cloning into 'eos'...
fatal: unable to access 'https://github.com/EOSIO/eos/': Could not resolve host: github.com

解决方案： 提示表明链接不上github网站，增加了香港服务器解决。

加入香港线路

sudo vim /etc/hosts

加入以下配置后保存

192.30.253.113 github.com

命令行增加配置

git config --global http.sslversion tlsv1

4.3 【错误3】Github下载提示端口错误

【信息交互提示】

duncanwang@duncanwang:~/work$ git clone https://github.com/EOSIO/eos --recursive

Cloning into 'eos'...
fatal: unable to access 'https://github.com/EOSIO/eos/': Failed to connect to github.com port 443: No route to host

duncanwang@duncanwang:~/work$ ping github.com

From 192.168.1.100 icmp_seq=4 Destination Host Unreachable
From 192.168.1.100 icmp_seq=5 Destination Host Unreachable

解决方案： 参考网上方法，运行以下命令，但是结果还是不行。

sudo iptables -I INPUT -p tcp --dport 443 -j ACCEPT

古哥的建议是先解决linux翻墙的问题，有点小难度。辉哥就重启了一下Ubuntu虚拟机，然后重新下载，发现下载成功了。

4.4 【成功】版本下载成功

4.5 【错误4】编译提示RAM空间不足

输入：

duncanwang@duncanwang:~/eos$ ./eosio_ build.sh

错误提示：

    Exiting now.

解决方法： 进到eos/scripts/路径，修改对应的sh文件，找到“Your system must have 7 or more Gigabytes of physical memory installed”字样，或者You must have at least %sGB of available storage to install EOSIO，将后面的exit 1命令去掉即可。

 if [ "${MEM_MEG}" -lt 7000 ]; then
        printf "\\tYour system must have 7 or more Gigabytes of physical memory installed.\\n"
        printf "\\tExiting now.\\n"
  ##     exit 1
    fi

顺道把硬盘不足的提示也注释掉，测试发现13G的空闲硬盘是可以编译成功的。

>   if [ "${DISK_AVAIL%.*}" -lt "${DISK_MIN}" ]; then
        printf "\\tYou must have at least %sGB of available storage to install EOSIO.\\n" "${DISK_MIN}"
        printf "\\tExiting now.\\n"
##       exit 1

4.6 【错误5】mongoDB无法下载

编译过程中错误提示：

分析： eosio_build_ubuntu.sh 查找 “Unable to download MongoDB at this time.”关键字可知这个语句执行失败。

--STATUS=$(curl -LO -w '%{http_code}' --connect-timeout 30 https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.6.3.tgz )

解决办法： 1）本地下载2个文件“mongodb-linux-x86_64-3.6.3.tgz”和“mongo-c-driver-1.9.3.tar.gz”，上传到虚拟机的软件存放目录“/home/duncanwang/work/software”， 2）修改脚本，重新运行 ./eosio_build.sh 即可解决。这2个下载文件可在辉哥的知识星球找到，也可以上官网下载。

        #STATUS=$(curl -LO -w '%{http_code}' --connect-timeout 30 https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.6.3.tgz)
        #if [ "${STATUS}" -ne 200 ]; then
        ##   printf "\\tUnable to download MongoDB at this time.\\n"
        ##   printf "\\n\\tExiting now.\\n\\n"
        ##   exit 1;
        #fi
        cp /home/duncanwang/work/software/mongodb-linux-x86_64-3.6.3.tgz "${HOME}/opt/"

##           if ! rm -f "${TEMP_DIR}/mongo-c-driver-1.9.3.tar.gz"
##           then
##               printf "\\n\\tUnable to remove file %s/mongo-c-driver-1.9.3.tar.gz.\\n" "${TEMP_DIR}"

##           exit 1;
##       fi
   cp /home/duncanwang/work/software/mongo-c-driver-1.9.3.tar.gz "${TEMP_DIR}/"

4.7 【错误6】RPC错误 编译过程中错误提示：

fatal: The remote end hung up unexpectedly

解决方法 提示RPC错误，古千峰反馈说，主网RPC服务不稳定。 1）辉哥想到的方法是把需要的 git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/llvm.git ， git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/clang.git 单独执行或者从windows下载转放到Ubuntu对应目录。编译的提示如下，还是搞不定。有大侠认为是因为我们下载的 llvm.git , clang.git 用的是最新版本的原因，没有用 release_40的版本，没有做重新尝试。

CMake Error at tools/clang/tools/diagtool/CMakeLists.txt:14 (target_link_libraries):
  The keyword signature for target_link_libraries has already been used with
  the target "diagtool".  All uses of target_link_libraries with a target
  must be either all-keyword or all-plain.

  The uses of the keyword signature are here:

   * cmake/modules/LLVM-Config.cmake:105 (target_link_libraries)
   * cmake/modules/AddLLVM.cmake:785 (target_link_libraries)

2）辉哥第二天早晨过来，把 /tmp/llvm-compiler 文件夹删除，重新编译一下，结果什么都成了。

4.8【成功】编译成功

完成4.7的删除文件夹重编译后，编译就成功了。

5. 编译总结

EOS成功的编译总是相同的，不成功的编译各个各的不幸。这儿总结下成功的步骤，一般是及其简单的。 1）、下载最新代码 git clone https://github.com/EOSIO/eos.git --recursive 3）、内存限制修改 ubuntu：eosio_build_ubuntu.sh 25行7000改成3000 4）、编译 ./eosio_build.sh 5）、安装命令：cd build 然后maker install

6. 【成功】私有节点运行

辉哥解决不了哪个安装测试错误的问题，就当做没有发生了。直接输入命令启动私有节点。
