An article briefly describes how to compile and install Golang

Golang is a programming language developed by Google. It has the characteristics of efficiency, reliability and simplicity, and is becoming more and more popular in server-side programming. You can install Golang using its own binary package or source code installation. Next, we will describe how to compile and install Golang.

1. Download the Golang source code

Visit the Golang official website (https://golang.org/), enter the "Downloads" interface, and download the latest Golang source code package.

2. Decompress the source package

Use the tar command to decompress the source package.

$ tar -C /usr/local -xzf go1.x.x.src.tar.gz

3. Compile the source code

Enter the directory where the Golang source code is located and execute the compilation command.

$ cd /usr/local/go/src/
$ ./all.bash

Compiling the command may take some time, please be patient.

4. Set environment variables

After compilation is completed, use the following command to set environment variables.

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

Among them, $GOPATH is the working directory, please modify it as needed.

5. Test Golang

Execute the following command to check whether Golang is installed normally.

$ go version

If the Golang version information is output, it means the installation is successful.

At this point, the compilation and installation of Golang is completed. During use, you also need to pay attention to the following points:

• When writing code, you should use the same tool chain as the Golang version.
• When upgrading Golang, you should completely uninstall the old version and then install the new version.
• During the installation process, running the command as the root user may cause permission problems. Please use the normal user to run the command.

Compiling and installing Golang is relatively cumbersome, but it can meet some special needs, such as debugging the Golang kernel or using the latest features of Golang. For ordinary users, just use the Golang or binary package that comes with the operating system to install Golang.
