How to Install Go in CentOS 7

Now extract the downloaded archive and install it to desired location on system.

Here /usr/local directory is used, but you can also use home directory (for shared hosting) or other location.

[root@linuxhelp1 ~]# tar -xvf go1.7.4.linux-amd64.tar.gz 
go/
go/AUTHORS
go/CONTRIBUTING.md
go/CONTRIBUTORS
go/LICENSE
go/PATENTS
go/README.md
go/VERSION
go/api/
go/api/README

go/api/go1.1.txt
go/api/go1.2.txt

go/test/varinit.go
go/test/writebarrier.go
go/test/zerodivide.go

Once it is downloaded, move the directory to local as follows.

[root@linuxhelp1 ~]# mv go /usr/local/

Setup Go Environment
It is required to set up the Go language environment variables for your project.

Generally, 3 environment variables such as GOROOT, GOPATH and PATH are needed. GOROOT is the location where Go package is installed on your system.

[root@linuxhelp1 ~]# export GOROOT=/usr/local/go

Now create the GOROOT directory path with the help of following command.

[root@linuxhelp1 ~]# mkdir -p /root/Projects/Proj1

GOPATH is the location of your work directory. For example, the directory used in this tutorial is ~/Projects/Proj1 .

[root@linuxhelp1 ~]# export GOROOT=$HOME/Projects/Proj1

Now set the PATH variable to access go binary system wide

[root@linuxhelp1 ~]# export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

All above environment will be set for your current session only. To make it permanent add above commands in ~/.bash_profile file

[root@linuxhelp1 ~]# go version
go version go1.7.4 linux/amd64

[root@linuxhelp1 ~]# go env
