How to install golang 1.7.5

Go language (Golang) is an efficient, reliable, and simple programming language developed by Google. In recent years, the Go language has gradually moved to the forefront of the programming world with its greater advantages, becoming the language of choice in cloud computing, big data, high concurrency and other fields, and its user base has become increasingly large. This article mainly introduces the installation process of golang 1.7.5.

1. Preparations before installation

During the installation process, we need to configure some environment variables in the Linux system environment. The specific operations are as follows:

1. Check the gcc version installed in the system:

gcc --version

If gcc is not installed in the system or the version is too low, you need to install a newer version of gcc:

sudo apt-get update
sudo apt-get install gcc

2. Check whether Mercurial has been installed in the system ：

hg --version

If Mercurial is not installed in the system, you need to install Mercurial:

sudo apt-get update
sudo apt-get install mercurial

2. Installation of golang 1.7.5

1. Download the source code from the official website

First, you need to download the latest version of golang source code from the golang official website (https://golang.org/dl/). Unzip the downloaded compressed file.

2. Configure environment variables

(1) Set the GOPATH environment variable:

export GOPATH=/usr/local/go

(2) Add the Go language binary file directory to the system PATH environment variable:

export PATH=$PATH:/usr/local/go/bin

(3) Save the environment variable configuration:

source ~/.bash_profile

(4) Test whether the environment variable is configured successfully through verification:

go version

If the version number of golang 1.7.5 is output , the installation is successful.

3. Test and verify whether golang is installed successfully

Write a Hello world program to test and verify whether golang is installed successfully:

1. Create directory:

mkdir -p $GOPATH/src/hello

2. Create the main.go file in the hello directory:

package main

import "fmt"

func main() {
    fmt.Println("Hello, world!")
}

3. Run the code:

go run main.go

If the terminal outputs the words Hello, world!, the verification is passed and golang is installed. .

Summary

Installing golang 1.7.5 is relatively simple. It mainly requires configuring system environment variables. Through the above steps, there should be no problem installing golang 1.7.5 in the Linux system. I hope this article will be helpful to you when installing golang 1.7.5.
