In Linux systems, there are many ways to install golang, such as manually downloading binary files for installation, using package management tools for installation, etc. In this article, we will introduce the steps to install golang using the yum package management tool.
yum is an automated software package installation tool that can easily and automatically install, update and uninstall software packages in Linux systems. Golang (also known as Go) is a strongly typed programming language and a programming environment mainly used to build efficient, concurrent, and concise applications.
Next we will follow the following steps to install golang's yum:
In the Linux system, we can Make it searchable in yum by adding the official golang yum source. This operation requires adding the following content to the /etc/yum.repos.d/golang.repo file:
[golang] name=golang baseurl=https://mirrors.ustc.edu.cn/golang/ enabled=1 gpgcheck=0
Among them, baseurl is the URL where the golang package is located. You can choose to use the appropriate URL as needed.
After adding the source file, we can use the following command to search for the versions provided by golang:
yum search golang
Run the above command Finally, the search operation will be performed based on the URL provided in the source file we added. Here you can see a list of all version information provided by golang. We need to find the version we want to install.
Use the following command, yum will automatically find, download and install the latest golang version from the Golang source file we added:
yum install golang
After the installation is completed, you can use the following command to verify whether golang is installed successfully:
go version
If the version number of golang is output, then indicate golang has been successfully installed.
Before using golang, we need to set the GOPATH environment variable. GOPATH refers to the golang working directory. All golang code and development tools will be installed in this directory. There are two ways to set GOPATH: one is to add GOPATH configuration in the Bash configuration file; the other is to set the GOPATH environment variable through the export command.
Add the GOPATH configuration in the Bash configuration file:
echo "export GOPATH=$HOME/go" >> ~/.bashrc
Then run the following command to update the configuration:
source ~/.bashrc
Use the export command to set the GOPATH environment variable:
export GOPATH=$HOME/go
Note: Here $HOME refers to the home directory of the currently logged in user. If you want to use another directory as the GOPATH, you can replace $HOME/go in the command with your own directory name.
Now, golang has been installed and the GOPATH environment variable has been set. You can start writing golang code and run them. We can use the following command to test whether the installation and configuration of golang is normal:
mkdir -p $GOPATH/src/hello echo 'package main; import "fmt"; func main() { fmt.Println("Hello Golang") }' > $GOPATH/src/hello/hello.go cd $GOPATH/src/hello go run hello.go
The above command will create a new golang project (folder and file) and output "Hello Golang". This shows that the installation and configuration of golang have been successfully completed.
Summary
Using the yum package management tool to install golang is a fast, simple and convenient way. It requires only a few commands to automatically install and configure golang, allowing us to start writing and running golang code immediately. Of course, golang can also be installed by manually downloading the binary file for installation or using other package management tools for installation. Here, we only introduce one of the methods. We can choose the appropriate method to install golang according to our actual needs.
