在CentOS 7上源码编译Golang 1.7

准备工作

• 一个"干净"的系统是必须的,本次操作在阿里云上完成。

  [root@snails ~]# hostnamectl set-hostname snails
  [root@snails ~]# hostnamectl
  Static hostname: snails
  Icon name: computer-vm
  Chassis: vm
  Machine ID: 7d26c16f116042a684ea498c9e2c240f
  Boot ID: e567275688e84ce3b72a11794dc8ac9b
  Virtualization: xen
  Operating System: CentOS Linux 7 (Core)
  CPE OS Name: cpe:/o:centos:centos:7
  Kernel: Linux 3.10.0-327.el7.x86_64
  Architecture: x86-64

  实践过程

  配置yum源

  CentOS 7配置

  wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

  安装git、gcc、vim

  yum -y install git gcc vim
  [root@snails ~]# git --version
  git version 1.8.3.1
  [root@snails src]# gcc --version
  gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-4)

  下载go 1.4分支

  [root@snails ~]#git clone -b release-branch.go1.4 https://github.com/golang/go.git go

  编译并配置环境变量

• 编译

  [root@snails ~]#cd go/src
  [root@snails ~]#./all.bash
  ALL TESTS PASSED
  Installed Go for linux/amd64 in /root/go
  Installed commands in /root/go/bin
  *** You need to add /root/go/bin to your PATH.

• 配置环境变量

  [root@snails ~]#cd ~ && mkdir -p golang/{src,pkg,bin}
  [root@snails ~]#vi /etc/profile
  export GOPATH=$HOME/golang
  export GOROOT=$HOME/go
  export PATH=$PATH:$GOROOT/bin
  [root@snails ~]# source /etc/profile
  [root@snails ~]# go version
  go version go1.4.3 linux/amd64

  更新go版本再次编译

• 更新go版本

  [root@snails ~]# mv go go-bootstrap
  [root@snails ~]# git clone https://github.com/golang/go.git
  [root@snails ~]# cd go

• 再次编译

  [root@snails go]# vi /etc/profile
  export GOROOT_BOOTSTRAP=$HOME/go-bootstrap
  [root@snails go]# source /etc/profile
  [root@snails go]# cd src/
  [root@snails src]# ./clean.bash(可选)
  [root@snails src]# ./all.bash

  ./clean.bash 是针对多次编译的情况下,先清除上一次编译结果。比如由1.7编译后,再升级到1.7.1版本;默认情况下可以不用。

实践验证

[root@snails src]# go version
go version devel +d872201 Thu Jul 7 04:06:52 2016 +0000 linux/amd64
