An article introduces the deployment method of golang environment

Go language is a programming language developed by Google. It aims to create a simple, efficient, and easy-to-learn programming language. In order to be able to use the Go language for development, we need to deploy the environment first. This article will introduce the deployment method of the golang environment.

1. Download the installation package

First we need to download the installation package corresponding to the corresponding platform from the official website (https://golang.org/dl/). This article chooses Linux. After downloading the 64-bit platform files, we need to unzip and install them.

2. Decompression and installation

Decompression and installation are very simple, you only need to decompress the downloaded file. Taking the Linux system as an example, we can use the following command to decompress:

tar -C /usr/local -xzf go1.16.4.linux-amd64.tar.gz

This command will decompress the Go language installation package to the /usr/local/go directory. Of course, you can also unzip the installation package to any other directory, as long as you ensure that the environment variables in subsequent operations are set correctly.

3. Set environment variables

After decompression is completed, we need to add the installation path of the Go language to the system environment variables to facilitate our subsequent operations. In the Linux environment, we can edit the /etc/profile file and add the following content:

export PATH=$PATH:/usr/local/go/bin

This command adds the bin directory of the Go language installation to the PATH environment variable, so that we can use go anywhere The command is executed.

Then execute the following command to activate the environment variables:

source /etc/profile

4. Test installation

After the environment variables are set, we can test whether the installation is successful by running the go version command. If the Go language version information is displayed, the installation is successful.

5. Set GOPATH

GOPATH is the working directory of the Go language, which contains the paths of all the codes we write and related tools. We need to set it in environment variables.

We can add the following lines to the ~/.bashrc or ~/.zshrc file:

export PATH=$PATH:/usr/local/go/bin
export GOPATH=$HOME/gopath
export PATH=$PATH:$GOPATH/bin

This command will set GOPATH to /home/username/gopath, where username is the current user’s Username, we can modify it according to our needs. In addition, we also added gopath's bin directory to the PATH environment variable so that we can easily use the tools in GOPATH.

6. Install common tools

When using Go language for development, we may need some common tools, such as git, dep, etc. You can install it through the following command:

sudo apt-get install git
go get -u github.com/golang/dep/cmd/dep

7. Summary

At this point, we have completed the environment deployment of the Go language. Through the above steps, we can install the Go language development environment and related tools and start developing using Go language. I hope this article can be helpful to friends who are learning Go language.
