How To Install Golang on FreeBSD

In this article, we will install go on FreeBSD OS:

We'll use the OPNsense firewall as an example of FreeBSD OS. 

OPNsense is an open-source, easy-to-use, and easy-to-build FreeBSD-based firewall and routing platform.

 For downloading Golang on FreeBSD OS follow these steps: 

1. Install Git 

•  $ sudo pkg update -f
• $​ sudo pkg install git

2. Install  Go 

We'll install  Go version "1.19.2" in this article. 

Now we want to make a source directory. This can be any directory you want.

• $ mkdir ~/src
• $ cd ~/src

We are going to use "wget" to download Go

•  $ wgethttps://go.dev/dl/go1.19.2.src.tar.gz

This downloads the archive to our system. Let’s unzip it.

• $ tar  xvfgo1.19.2.src.tar.gz 

Now that it’s unzipped, we can verify the files extracted.

Move it to our local folder.

• $ sudo mv go /usr/local 

Now  open up our profile with text editor. Install any text editor (ex: vim)

• $ pkg install vim
• $ sudo vim ~/.profile

In that file, we want to add the following:

     1. we’re doing here is setting our go root to /usr/local/go:

• export GOROOT=/usr/loc​al/go​

     2.  Then we’re putting the gopath and go root into our main path.

• export PATH=$GOPATH/bin:$GOROOT/bin:$PATH
• export PATH=$PATH:/usr/local/go/bin
• set path = ($path /usr/local/go/bin /root/.gopkg/bin)
  

Then we’ll save that file.

3. Now  verify our installation.

• $ go version
