How to run your first go program on Linux

❝

Friends who are preparing to learn go will install and use it directly on Windows at the beginning. Today I will write an installation tutorial on Linux for you.

1. Install GO

Open the official website of gohttps://golang.org/dl/, and directly install the one selected in the click box. Right-click the mouse and there will be an address. Save this address and use the wget command below. Just download itExecute the commandwget https://golang.org/dl/go1.14.4.linux-amd64.tar.gz, download itExtract go to Under /usr/local

Execution instructionstar -xzf go1.14.4.linux-amd64.tar.gz -C /usr/local/

After decompression is completed, it will be directly under /usr/local go folder

Up to this step, our go has been installed. Next, we need to configure environment variables.

2. Configure environment variables

GOROOT: This is the installation location of go, in this article it is /usr/ local/go GOPATH: This is the directory of the project

The configuration on Windows is like thisNext we need to configure the environment variables of go on Linux, in the file /etc/profile Add the following code

<span style="display: block; background: url(https://imgkr.cn-bj.ufileos.com/97e4eed2-a992-4976-acf0-ccb6fb34d308.png); height: 30px; width: 100%; background-size: 40px; background-repeat: no-repeat; background-color: #282c34; margin-bottom: -7px; border-radius: 5px; background-position: 10px 10px;"></span><code class="hljs" style="overflow-x: auto; padding: 16px; color: #abb2bf; display: -webkit-box; font-family: Operator Mono, Consolas, Monaco, Menlo, monospace; font-size: 12px; -webkit-overflow-scrolling: touch; letter-spacing: 0px; padding-top: 15px; background: #282c34; border-radius: 5px;">export GOROOT=/usr/local/go<br/>export GOPATH=/goLearn<br/>export PATH=$PATH:$GOROOT/bin<br/></code>

and execute source ./profileExecute go version to check whether go is installed successfully. If the installation is successful, the following figure will appear. (If it is inconsistent with the version downloaded by Kaka, it is the version number you downloaded yourself)

3. Execute the first GO program on Linux

This directory must be consistent with the set GOPATH, which is the goLearn directory

Create src in this directory of golearn, and then store your project in this directory That’s it

This case is just a simple implementation process. In order to only demonstrate the execution problem of the GO program, Kaka will always output some articles about go later and then execute this program to check whether it can be executed successfully. There are many ways to execute go programs. Here we just use the go run command for demonstration. This is just a simple implementation process. The main purpose of this article is to install GO on Linux.

If you happen to want to know about go, then you can continue to check Kaka’s articles in the GO column of this site.
