Customized installation Golang on Linux

COMPILERS FOLDER

Example: mkdir {compilers,compilers/c,compilers/go,compilers/rust}

mkdir {compilers,compilers/go}
cd compilers/go

VERSION

mkdir go1.17.6.linux-amd64 && cd go1.17.6.linux-amd64

DOWNLOAD

wget https://dl.google.com/go/go1.17.6.linux-amd64.tar.gz

• Write the command dir then hit Enter to check if the folder go1.17.6.linux-amd64.tar.gz is completely downloaded.

EXTRACT & REMOVE

tar -xvf go1.17.6.linux-amd64.tar.gz

rm go1.17.6.linux-amd64.tar.gz

WORK SPACE

IF there is no such file or directory "~/dev/golang/workspace", then create this directory

cd ~
mkdir {dev,dev/golang,dev/golang/workspace}

Or go to the Golang development directory like so

cd ~/dev/golang/workspace

Workspace required to enable Golang versions

mkdir go1.17.6 && cd go1.17.6
mkdir {bin,pkg,src,src/github.com,src/github.com/your-github-name}

An example of what a workspace looks like

workspace
├── go1.15.7
├── go1.16
├── go1.16.2
├── go1.16.3
├── go1.16.4
└── go1.17.6
    ├── bin
    ├── pkg
    └── src
        └── github.com
            └── your-github-name

PATH

Open the terminal path file by writing

gedit $HOME/.bashrc

OR

gedit ~/.bashrc

Copy, Paste & Save the following code at the end of the .bashrc file, then close it.

## Changes made to the .bashrc file by myself
## GOROOT
export GOROOT=$HOME/compilers/go/go1.17.6.linux-amd64/go
export PATH=$PATH:$GOROOT/bin

## GOPATH
export GOPATH=$HOME/dev/golang/workspace/go1.17.6
export PATH=$PATH:$GOPATH/bin

## GOBIN
export GOBIN=${GOPATH}/bin

Note: only one version must be active

CHECK

Close the terminal and open it again

cd go-rest-api/go-mock-rest-api

go build

OR

go build -o alternative-project-name main.go
