How to install Golang environment on Linux system

Golang is a programming language developed by Google. Its main feature is to write high-performance and high-concurrency programs. The learning cost of Golang language is relatively low, and the development speed is very fast. It is currently widely used in network programming and server-side development. This article will introduce how to install the Golang programming language on a Linux system.

1. Preparation before installation

Before installing Golang, we need to check whether the library for installing the Linux operating system has been installed normally. In most Linux operating systems, the Golang language environment is often installed together with the C language environment, so we need to first confirm whether the C language environment has been installed correctly. Use the following command to check your existing C language version:

gcc -v

If you have not installed the C language environment, then we can use the following command to install it. The Ubuntu/Debian operating system can be installed through the following command:

sudo apt-get install gcc

On the CentOS/Fedora/RHEL operating system, you need to use the following command to install:

sudo yum install gcc

After confirming that the C compiler installation is complete, we can start the installation of Golang.

2. Installation steps

First, we need to download the corresponding installation file from the Golang official website. The download address can be obtained through the following command:

curl -O https://dl.google.com/go/go-version.linux-arch.tar.gz

where version is the current Golang version number, and arch is the system architecture (such as amd64, 386, arm, etc.).

After the download is completed, use the following command to decompress the file:

sudo tar -C /usr/local -xzf go-version.linux-arch.tar.gz

Next, we need to set the related environment variables of the Golang language. You can edit the .bashrc file in the user directory (for other shells, please modify it accordingly):

vim ~/.bashrc

Add the following code at the end:

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

where GOPATH is the working directory, which can be done according to personal preferences Revise. After the addition is completed, use the following command to make the environment variable take effect:

source ~/.bashrc

After the installation is completed, we can use the following command to verify whether the installation is successful:

go version

If successful, the current installation version information will be displayed .

3. In-depth study of Golang

The best way to learn a programming language is to read other people's code. There are many high-quality open source projects in the Golang community for everyone to learn from. The following are some commonly used code libraries in the Golang community:

• Gin: Web framework
• Gorm: ORM framework
• Viper: Configuration management tool
• Cobra: Command line application framework

The above are some mainstream tools in the Golang community. If you need to use some other open source libraries, you can search for related projects on Github.

4. Summary

This article mainly introduces the steps to install the Golang programming language on a Linux system and how to set related environment variables. I hope this article can provide some reference for beginners. In the process of learning Golang, we should read as much as possible other people's code and become familiar with the use of some open source libraries to facilitate our own programming work.
