Before starting the text, we need to introduce the meaning of the following environment variables:

1. GOROOT: Go language installation directory.
2. GOPATH: Go language working directory, used to store project source code and related packages.
3. PATH: The system environment variable stores the paths of some system program files. Add the Go language bin directory to this environment variable to facilitate the execution of Go language commands.

Now, we start to introduce the installation method of Go 1.7. The installation method for Go 1.7 is basically the same as the installation method for previous versions.

1. Download the installation package
   The Go 1.7 installation package can be found on the official website https://golang.org/dl/. You can download the corresponding installation package according to your operating system. Go1.7 switches to https because it involves security issues. When downloading, be sure to select https.
2. Installation
   For different operating systems, the installation methods will be slightly different.

Windows system: The suffix of the installation package is msi. You can directly double-click the installation package and follow the prompts to install it.

Then, you need Add environment variables. Open the /etc/profile file and add the following content at the end of the file:

export PATH=$PATH:/usr/local/go/bin

After saving the file, execute the following command to set the environment variables Effective immediately:

After this, you can check the Go language version through go version. If the following information is output, the installation is successful:

go version go1.7 linux/amd64

3. Configure environment variables
   After the software installation is completed, add the paths of GOROOT and GOPATH variables to the user's environment variables. This needs to be added to the user's environment variables (note not system environment variables). After setting it up, add %GOROOT%\bin to the PATH environment variable path to indicate the path where the executable file is located. You can use Go language commands directly on the command line.

Summary
As an emerging language, Go language is gradually becoming popular. The release of Go 1.7 has enhanced the stability, reliability and development efficiency of Go language. When installing, you need to pay attention to the configuration of environment variables, otherwise it may be affected in the later development process.
