Go installation and configuration

2. Three environment variables in go
   
   1. Goroot
      The path to the go language installation, such as Mac:/usr/local/go, similar to Java_home in Java
   2. Gopath
      Gopath represents the address where the package resides and can be set more than one.
      Assume: Gopath=~/go1:~/go2,goroot=/usr/local/go, the package is referenced in the code: Github.com/bitly/nsq/util
      Then: Go at compile time will be in order to find the source code in the following directory:
      ~/go1/src/github.com/bitly/nsq/util
      ~/go2/src/github.com/bitly/nsq/util
      /usr/local/go/src/github.com/bitly/nsq/util
   3. PATH
      Path to the executable instance
4. Go command
   
   • Learning Document Https://github.com/hyper-carrot/go_command_tutorial
   • Go Display command-related help information
   • Go build compiles packages and dependencies that generate executables in the directory where the command is executed
   • Go clean cleanup compiles the generated files
   • Go env display GO environment variable
   • Go FMT Format code
   • Go install compile and install packages, dependencies
   • Go run to compile and run the Go program
   • Go get Gets or updates the code packages and their dependencies, and compiles and installs them
   • Run test code for GO test
6. Go Web Development Framework
   
   1. Beego http://beego.me/
      MVC framework, the author of the Chinese, the framework of Chinese documents rich, large user groups, easy to communicate. Learning difficulty is low.
   2. Revel http://revel.github.io/
