Go (often referred to as golang) is a free and open source programming language created at Google in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. It is a compiled, statically typed language in the tradition of Algol and C, with garbage collection, limited structural typing, memory safety features and CSP-style concurrent programming features added.

The language was announced in November 2009; it is used in some of Google's production systems,as well as by other firms. Two major implementations exist: Google's Go compiler, "gc", is developed as open source software and targets various platforms including Linux, OS X, Windows, various BSD and Unix versions, and since 2015 also mobile devices, including smartphones.A second compiler, gccgo, is a GCC frontend. The "gc" toolchain is self-hosting since version 1.7 
 
Download and Install Go Language: 
Switch to the root user.

### Ubuntu 16.04 / 14.04 ###

# apt-get update
# apt-get -y upgrade

### CentOS / RHEL / Fedora ###

# yum -y update
</pre>
Download the Go language binary package using the following command. Alternatively, you can visit <a href="https://golang.org/dl/">Go Language download</a> page to download the latest version of Go. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;"># wget https://storage.googleapis.com/golang/go1.7.1.linux-amd64.tar.gz</pre>
Extract the archive and move it to /usr/local. You can also place the Go lang binary to your custom location instead of /usr/local. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;"># tar -zxvf go1.7.1.linux-amd64.tar.gz -C /usr/local/</pre>
Setup Go Environment variables: 
 
 
Setup two important variables for Go, GOROOT (PATH) and GOPATH. Add /usr/local/go/bin to your path variable.run below command (temporary) or place the following command in /etc/profile or $HOME/.profile file for persistent across sessions. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">export PATH=$PATH:/usr/local/go/bin</pre>
For Go custom location replace /usr/local/go/bin/ with /path/to/bin/ directory. 
 
 
GOPATH is a Go environment variable for your project workspace. Create a workspace directory called "projectwork" in your home directory. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">mkdir $HOME/projectwork</pre>
Set GOPATH variable run below command (temporary) or place the following command in /etc/profile or $HOME/.profile file for persistent across sessions. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">export GOPATH=$HOME/projectwork</pre>
Verify Go Installation: 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;"># go version
go version go1.7.1 linux/amd64</pre>
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;"># go env

Create your first project: 
The workspace called "projectwork" located in $HOME directory. I am a root user, in my case "/root/projectwork" is my workspace. goto your workspace using below command 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;"># cd $GOPATH
or
# cd $HOME/work</pre>
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;"># mkdir -p src/hello</pre>

and place the following content in the hello.go file. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">package main

import "fmt"

func main() {
 fmt.Printf("Welcome To hackthesec\n")
}</pre>
Compile it with go command. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;"># go install hello</pre>
go command will put an executable command (hello) inside the bin directory of your workspace. Execute the executable using the following command. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;"># $GOPATH/bin/hello</pre>

Installing packages</div>
<div>
R packages are packages that extend the capabilities of R. Enter R:</div>
<div>
<pre style="background-attachment: initial; background-clip: initial; background-color: #363636; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border-radius: 7px; border: 1px solid rgb(221, 221, 221); font-stretch: inherit; margin-bottom: 15px; margin-top: 15px; overflow-x: auto; overflow-y: hidden; padding: 18px 20px; vertical-align: baseline;">R</pre>
</div>
<div>
There are two ways to install R packages. First of all, if you want to install a package only for the current user, you can execute the following in R:</div>
<div>
<pre style="background-attachment: initial; background-clip: initial; background-color: #363636; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border-radius: 7px; border: 1px solid rgb(221, 221, 221); font-stretch: inherit; margin-bottom: 15px; margin-top: 15px; overflow-x: auto; overflow-y: hidden; padding: 18px 20px; vertical-align: baseline;">install.packages("name")</pre>
</div>
<div>
If you want to install a package available for all users on the system, there are multiple mirrors for both R and its packages. Execute:</div>
<div>
<pre style="background-attachment: initial; background-clip: initial; background-color: #363636; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border-radius: 7px; border: 1px solid rgb(221, 221, 221); font-stretch: inherit; margin-bottom: 15px; margin-top: 15px; overflow-x: auto; overflow-y: hidden; padding: 18px 20px; vertical-align: baseline;">su - -c "R -e \"install.packages('name', repos = 'http://cran.rstudio.com/')\""</pre>
</div>
<div>
Replace name with the package name.</div>
<div>
<div>
Please note: that you do not want to install R with packages on a server with less than 1 GB RAM.</div>
