【CM】安装

GIT

sudo yum install -y git

GO

检查服务器 yum 里是否有 golang

yum search golang 

Go官网下载地址：https://studygolang.com/dl
Go官方镜像站（推荐）: https://golang.google.cn/dl/

wget https://golang.google.cn/dl/go1.18.linux-amd64.tar.gz

sudo mkdir -p /usr/local/go  # 创建目录
sudo chmod a+rw /usr/local/go
tar zxvf go1.11.5.linux-amd64.tar.gz -C /usr/local/go # 解压
cd /usr/local/go
mv ./go/* ./
rmdir ./go

第二种

Linux下有两个文件可以配置环境变量，其中/etc/profile是对所有用户生效的；$HOME/.bash_profile是对当前用户生效

wget https://dl.google.com/go/go1.12.5.linux-amd64.tar.gz
tar -xzvf go1.12.5.linux-amd64.tar.gz -C /usr/local/
mkdir -p /home/gopath
cat >> /etc/profile <<EOF
export GOROOT=/usr/local/go
export GOPATH=/home/gopath
export PATH=\$PATH:\$GOROOT/bin
EOF
source /etc/profile

go version

#auto install golang
wget https://golang.google.cn/dl/go1.17.8.linux-amd64.tar.gz
sudo mkdir -p /usr/local/go
tar zxvf go1.18.linux-amd64.tar.gz -C /usr/local
rm -f go1.18.linux-amd64.tar.gz
mkdir -p /home/gopath
cat >> /etc/profile <<EOF
export GOROOT=/usr/local/go
export GOPATH=/home/gopath
export PATH=\$PATH:\$GOROOT/bin
EOF
source /etc/profile

DOCKER和docker-compose

Centos7上安装docker - 风止雨歇 - 博客园 (cnblogs.com)

 sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
 
sudo chmod +x /usr/local/bin/docker-compose

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

docker-compose --version

gcc

1. 检查 gcc 版本

gcc --version

显示结果若 < 7.3，则执行下面步骤升级

1. 升级 gcc

sudo yum install centos-release-scl
sudo yum install devtoolset-7-gcc*
scl enable devtoolset-7 bash

注意：第三条指令scl enable devtoolset-7 bash 只是在当前会话中升级了gcc，如果想每次登录gcc自动升级，可以把scl enable devtoolset-7 bash 放在 ~/.bash_profile 文件中。

cat >> ~/.bash_profile <<EOF
scl enable devtoolset-7 bash
EOF

环境搭建

源码下载

• 下载chainmaker源码到本地

$ git clone -b v2.2.0_alpha https://git.chainmaker.org.cn/chainmaker/chainmaker-go.git

• 下载证书生成工具源码到本地

$ git clone -b v2.2.0 https://git.chainmaker.org.cn/chainmaker/chainmaker-cryptogen.git

源码编译

• 编译证书生成工具

$ cd chainmaker-cryptogen
$ make

make失败，使用代理

go env -w GOPROXY=https://goproxy.cn

配置文件生成

• 将编译好的chainmaker-cryptogen，软连接到chainmaker-go/tools目录

# 进入工具目录
$ cd chainmaker-go/tools

# 软连接chainmaker-cryptogen到tools目录下
$ ln -s ../../chainmaker-cryptogen/ .
