Install Go1.6 from source code to CentOS 7 in China network environment

Https://github.com/northbright/Notes/blob/master/Golang/china/install-go1.6-from-source-on-centos7-in-china.md

Background

• In the current Chinese network environment, we are unable to access Google's services, including golang.org.
• Downloading a precompiled binary go release from a third-party website may present a risk of third-party source code injection, such as previous xcodeghost.
• GoThe authoritative warehouse address is https://go.googlesource.com/go, and there is also a mirrored warehouse in Https://github.com/golang/go.
• At least for now, we have access to GitHub:-)

Problem

• The Go1.6 compilation process requires the Go1.4 of the two in the implementation of Bootstrap (bootstrap) (simply: go requires go itself to compile).

Solution Solutions

• Get the source code for go from GitHub's Go warehouse image.
• First compile the Go1.4 (only need gcc and glibc-devel , do not need go to compile).
• Compile the Go1.6 using a compiled Go1.4 binary file.

Steps

2. If you have previously installed the old version of Go, clear the $GOPATH, $GOROOT variable.

4. Install Git.

   • ConfigurationGit
     • git config --global user.email "email-for-github"
     • git config --global user.name "user name"
   • Create SSH key and add public key to your GitHub account.
     • ssh-keygen -t rsa -b 2048
     • Copy ~/.ssh/id_rsa.pub the public key to GitHub SSH settings to add a new SSH key

6. Installation gcc andglibc-devel

   • sudo yum install gcc glibc-devel

8. Compiling from source code install Go1.4

   • cd ~/
   • git clone git@github.com:golang/go.git
   • cd go
   • git checkout -b 1.4.3 go1.4.3
   • cd src
   • ./all.bash

10. Copy ~/go to $GOROOT_BOOTSTRAP (default value is ~/go1.4 )

    • cp ~/go ~/go1.4 -rf

12. Compiling from source code install Go1.6

    • cd ~/go
    • git clean -dfx
    • git checkout -b 1.6 go1.6
    • cd src
    • ./all.bash

14. Set up $GOPATH and add go binary path to$PATH

    • sudo vi /etc/profile

        # Golang Env  export PATH=$PATH:/home/xx/go/bin  export GOPATH=/home/xx/go-projects

16. Restart and test

    • sudo reboot

    • go version

        go version go1.6 linux/amd64
