centos 7 golang1

CentOS 7 is a widely used Linux distribution known for its stability and security. As a professional Golang developer, I have found CentOS 7 to be an excellent platform for developing Go applications. In this article, I will discuss the various aspects of using Golang 1.10 on CentOS 7.

Setting up Golang on CentOS 7

To begin developing Go applications on CentOS 7, we first need to install the Golang runtime. Thankfully, CentOS 7 provides a simple way to install Golang via the default package manager, yum. We can do this by running the following command:

sudo yum install golang

This command will download and install the latest version of Golang available in the CentOS 7 repositories. Once the installation is complete, we can verify the installation by running the following command:

go version

If everything is set up correctly, the command should print the version of Golang installed, which should be 1.10 or above.

Working with Go Modules

Go modules were introduced in Golang 1.11 as a dependency management solution for Go projects. While CentOS 7 typically ships with older versions of Golang, we can still make use of Go modules in our development process.

To enable Go modules for a project, we need to initialize it within a module-aware directory. We can do this by running the following command:

go mod init example.com/myproject

This command creates a go.mod file that keeps track of the dependencies used in your project. We can then use the go get command to add required dependencies to our project:

go get example.com/dependency

The go.mod file will be automatically updated with the new dependency, and we can start using it in our project.

Building and Running Go Applications

Once our project is set up and dependencies are added, we can build and run our Go applications on CentOS 7. The go build command compiles all the Go files in the current directory and generates an executable binary. We can execute the following command to build our application:

go build

This command will create an executable binary named after the current directory. We can then run this binary by executing:

./myproject

If everything is set up correctly, our Go application should now be running and accessible via the specified port or endpoint.

Conclusion

Golang 1.10 on CentOS 7 provides a reliable and stable platform for developing and running Go applications. By following the outlined steps, we can easily set up Golang on CentOS 7, make use of Go modules for dependency management, and build and run our Go applications seamlessly. As a professional Golang developer, CentOS 7 has proven to be an excellent choice for developing robust and efficient Go applications.
