Go also known as golang, is a compiled computer programming language developed by google. It is loosely based on the C language but designed to overcome some of its short comings. It is a general purpose language and can be used from server-side development to games and streaming media. It can easily be installed on a CentOS system. This guide assumes you have at least a basic working installation of a Linux system.<\/p>\n
Clean up repositories<\/p>\n
yum clean all<\/p>\n
Ensure everything is up to date<\/p>\n
yum update<\/p>\n
Change directories<\/p>\n
cd \/usr\/src<\/p>\n
Download the compiled package, you can find the most recent release on the downloads page<\/a>.<\/p>\n wget https:\/\/storage.googleapis.com\/golang\/go1.8.3.linux-amd64.tar.gz<\/p>\n Uncompress the archive<\/p>\n tar xfvz go1.8.3.linux-amd64.tar.gz<\/p>\n Move the binary and its applicable files to \/usr\/local<\/p>\n mv go \/usr\/local\/<\/p>\n Export the following<\/p>\n export GOROOT=\/usr\/local\/go<\/p>\n GOROOT defines the path you placed the Go package in<\/p>\n export GOPATH=$HOME\/go-project<\/p>\n GOPATH tells go where your project is located, this can be anywhere<\/p>\n export PATH=$GOPATH\/bin:$GOROOT\/bin:$PATH<\/p>\n This appends both the GOPATH and GOROOT to your $PATH. You can also add this to your .bash_profile to automatically export these variables upon logging in.<\/p>\n By typing \u2018go version\u2019 it will give you a print out of the version you currently have running<\/p>\n # go version By typing \u2018go env\u2019 it will show the environment variables that are currently in use.<\/p>\n # go env Create the project directory you exported earlier:<\/p>\n mkdir $HOME\/go-project<\/p>\n Change to that directory:<\/p>\n cd $HOME\/go-project<\/p>\n Create a new file:<\/p>\n nano hello.go<\/p>\n Insert the following lines:<\/p>\n package main Execute the file:<\/p>\n go run hello.go<\/p>\n The file should print the following<\/p>\n # go run hello.go That\u2019s it, you should now have a working Go installation.<\/p>\n Aug 7, 2017LinuxAdmin.io<\/p>\nVerify Go Installation<\/h2>\n
