Go<\/strong>\u00a0(also referred to as\u00a0GoLang<\/strong>) is an open source and lower level programming language designed to enable users to easily write simple, reliable, and highly efficient computer programs.<\/p>\n

Developed in 2007 at\u00a0Google<\/strong>\u00a0by a team of programmers \u2013\u00a0Robert Griesemer<\/strong>,\u00a0Rob Pike<\/strong>, and\u00a0Ken Thompson<\/strong>, it is a compiled, statically typed language same as other system languages such as\u00a0C<\/strong>,\u00a0C++<\/strong>,\u00a0Java<\/strong>\u00a0and many more.<\/p>\n

GoLang<\/strong>\u00a0is highly productive, and readable with support for networking and multiprocessing and it is scalable in extensive systems as well. Below is a list of a few well known open source projects developed using\u00a0GoLang<\/strong>:<\/p>\n

    \n
  1. Docker<\/a><\/li>\n
  2. Kubernetes<\/li>\n
  3. Lime<\/li>\n
  4. InfluxDB<\/li>\n
  5. Gogs (Go Git Service) among others.<\/li>\n<\/ol>\n

    Install GoLang in Linux Systems<\/h3>\n

    1.<\/strong>\u00a0Go to\u00a0https:\/\/golang.org\/dl\/<\/a>\u00a0and download the latest version (i.e\u00a01.7.3<\/strong>) of GoLang in an archive file as follows:<\/p>\n

    $ cd ~\/Downloads\r\n$ wget -c https:\/\/storage.googleapis.com\/golang\/go1.7.3.linux-amd64.tar.gz<\/pre>\n
    2.<\/strong>\u00a0Next, check the integrity of the tarball by\u00a0verifying the SHA256 checksum of the archive file<\/a>\u00a0using the\u00a0shasum<\/strong>\u00a0command as below, where the flag\u00a0-a<\/code>\u00a0is used to specify the algorithm to be used:<\/p>\n
    $ shasum -a 256 go1.7.3.linux-amd64.tar.gz\r\n\r\nead40e884ad4d6512bcf7b3c7420dd7fa4a96140  go1.7.3.linux-amd64.tar.gz<\/strong>\r\n<\/pre>\n
    Important<\/strong>: To show that the contents of the downloaded archive file are the exact copy provided on the GoLang website, the\u00a0256-bit<\/strong>\u00a0hash value generated from the command above as seen in the output should be the same as that provided along with the download link.<\/p>\n
    If that is the case, proceed to the next step, otherwise download a new tarball and run the check again.<\/p>\n
    3.<\/strong>\u00a0Then extract the tar archive files into\u00a0\/usr\/local<\/strong>\u00a0directory using the command below.<\/p>\n
    $ sudo tar -C \/usr\/local -xvzf go1.7.3.linux-amd64.tar.gz\r\n<\/pre>\n
    Where,\u00a0-C<\/code>\u00a0specifies the destination directory..<\/p>\n
    Configuring GoLang Environment in Linux<\/h3>\n
    4.<\/strong>\u00a0First, setup your\u00a0Go workspace<\/strong>\u00a0by creating a directory\u00a0~\/go_projects<\/code>\u00a0which is the root of your workspace. The workspace is made of three directories namely:<\/p>\n
      \n
    1. bin<\/code>\u00a0which will contain Go executable binaries.<\/li>\n
    2. src<\/code>\u00a0which will store your source files and<\/li>\n
    3. pkg<\/code>\u00a0which will store package objects.<\/li>\n<\/ol>\n
      Therefore create the above directory tree as follows:<\/p>\n
      $ mkdir -p ~\/go_projects\/{bin,src,pkg}\r\n$ cd ~\/go_projects\r\n$ ls\r\n<\/pre>\n
      5.<\/strong>\u00a0Now it\u2019s time to execute\u00a0Go<\/strong>\u00a0like the rest of Linux programs without specifying its absolute path, its installation directory must be stored as one of the values of\u00a0$PATH environment variable<\/a>.<\/p>\n
      Now, add\u00a0\/usr\/local\/go\/bin<\/code>\u00a0to the\u00a0PATH<\/strong>\u00a0environment variable by inserting the line below in your\u00a0\/etc\/profile<\/strong>\u00a0file for a system-wide installation or\u00a0$HOME\/.profile<\/strong>\u00a0or\u00a0$HOME.\/bash_profile<\/strong>\u00a0for user specific installation:<\/p>\n
      Using your preferred editor, open the appropriate user profile file as per your distribution and add the line below, save the file and exit:<\/p>\n
      export  PATH=$PATH:\/usr\/local\/go\/bin\r\n<\/pre>\n
      6.<\/strong>\u00a0Then, set the values of\u00a0GOPATH<\/code>\u00a0and\u00a0GOBIN<\/code>\u00a0Go environment variables in your user profile file (~\/.profile<\/strong>\u00a0or\u00a0~\/bash_profile<\/code>) to point to your workspace directory.<\/p>\n
      export GOPATH=\"$HOME\/go_projects\"\r\nexport GOBIN=\"$GOPATH\/bin\"\r\n<\/pre>\n
      Note<\/strong>: If you installed\u00a0GoLang<\/strong>\u00a0in a custom directory other than the default (\/usr\/local\/<\/strong>), you must specify that directory as the value of\u00a0GOROOT<\/strong>\u00a0variable.<\/p>\n
      For instance, if you have installed\u00a0GoLang<\/strong>\u00a0in home directory, add the lines below to your\u00a0$HOME\/.profile<\/strong>\u00a0or\u00a0$HOME\/.bash_profile<\/strong>\u00a0file.<\/p>\n
      export GOROOT=$HOME\/go\r\nexport PATH=$PATH:$GOROOT\/bin\r\n<\/pre>\n
      7.<\/strong>\u00a0The final step under this section is to effect the changes made to the user profile in the current bash session like so:<\/p>\n
      $ source ~\/.bash_profile\r\nOR\r\n$ source ~\/.profile\r\n<\/pre>\n
      Verify GoLang Installation<\/h3>\n
      8.<\/strong>\u00a0Run the commands below to view your\u00a0Go<\/strong>\u00a0version and environment:<\/p>\n
      $ go version\r\n$ go env\r\n<\/pre>\n
      \n
      \"Check<\/a><\/p>\n
      Check GoLang Version and Environment<\/p>\n<\/div>\n
      Type the following command to display usage information for\u00a0Go<\/strong>\u00a0tool, which manages\u00a0Go<\/strong>\u00a0source code:<\/p>\n
      $ go help\r\n<\/pre>\n
      9.<\/strong>\u00a0To test your if your\u00a0Go<\/strong>\u00a0installation is working correctly, write a small\u00a0Go hello<\/strong>\u00a0world program, save the file in\u00a0~\/go_projects\/src\/hello\/<\/strong>\u00a0directory. All your GoLang source files must end with the\u00a0.go<\/code>\u00a0extension.<\/p>\n
      Begin by creating the hello project directory under\u00a0~\/go_projects\/src\/<\/strong>:<\/p>\n
      $ mkdir -p ~\/go_projects\/src\/hello\r\n<\/pre>\n
      Then use your favorite editor to create the\u00a0hello.go<\/code>\u00a0file:<\/p>\n
      $ vi ~\/go_projects\/src\/hello\/hello.go\r\n<\/pre>\n
      Add the lines below in the file, save it and exit:<\/p>\n
      package main \r\n\r\nimport \"fmt\"\r\n\r\nfunc main() {\r\n    fmt.Printf(\"Hello, you have successfully installed GoLang in Linux\\n\")\r\n}\r\n<\/pre>\n
      10.<\/strong>\u00a0Now, compile the program above as using\u00a0go<\/strong>\u00a0install and run it:<\/p>\n
      $ go install $GOPATH\/src\/hello\/hello.go\r\n$ $GOBIN\/hello\r\n<\/pre>\n
      \n
      \"First<\/a><\/p>\n
      First GoLang Program<\/p>\n<\/div>\n
      If you see the output showing you the message in the program file, then your installation is working correctly.<\/p>\n
      11.<\/strong>\u00a0To run your\u00a0Go<\/strong>\u00a0binary executables like other Linux commands, add\u00a0$GOBIN<\/strong>\u00a0to your\u00a0$PATH<\/strong>\u00a0environment variable.<\/p>\n
