Getting Started with Go (Golang) on Rocky Linux 8

#### Prerequisites Before you begin, ensure you have: - A server running Rocky Linux 8 (This guide is tested with Rocky Linux 8) - A user account with sudo privileges - Basic familiarity with the command line #### Step 1: Install Go (Golang) First, download the latest stable version of Go from the official website: ```bash wget https://golang.org/dl/go1.18.5.linux-amd64.tar.gz ``` Extract the downloaded archive and install Go to `/usr/local`: ```bash sudo tar -C /usr/local -xzf go1.18.5.linux-amd64.tar.gz ``` #### Step 2: Set Go Environment Variables Set Go environment variables by adding them to your shell configuration file (e.g., `~/.bashrc` or `~/.profile`): ```bash echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.bashrc echo 'export GOPATH=$HOME/go' >> ~/.bashrc echo 'export PATH=$PATH:$GOPATH/bin' >> ~/.bashrc source ~/.bashrc ``` #### Step 3: Verify Go Installation Verify that Go is installed correctly by checking the version: ```bash go version ``` #### Step 4: Create a Simple Go Program Create a directory for your Go workspace and navigate into it: ```bash mkdir -p ~/go/src/hello cd ~/go/src/hello ``` Create a new Go file `hello.go` and open it with a text editor: ```bash nano hello.go ``` Add the following Go code to `hello.go`: ```go package main import "fmt" func main() { fmt.Println("Hello, Go on Rocky Linux 8!") } ``` Save and close the file. #### Step 5: Build and Run the Go Program Build the Go program using the `go build` command: ```bash go build ``` Run the executable generated: ```bash ./hello ``` You should see the output: ``` Hello, Go on Rocky Linux 8! ``` #### Conclusion You have successfully installed Go (Golang) on Rocky Linux 8 and created a simple Go program. Begin exploring more features of Go and developing applications using this powerful programming language. **Additional Resources:** - **Official Go Documentation:** [https://golang.org/doc/](https://golang.org/doc/) - **Rocky Linux Documentation:** [https://docs.rockylinux.org/](https://docs.rockylinux.org/)
