Discuss how to deploy golang on winserver

In the current technological wave, Go language (also known as golang) has become a popular programming language, especially when writing high-performance web applications and distributed systems. Therefore, deploying golang on winserver is an important task but may even be a challenge for many IT practitioners. In this article, we will explore how to deploy golang on winserver.

1. Download and install Go

First, we need to download the golang installation package. On the official website (https://golang.org/dl/), select the version suitable for your system and download the corresponding installation package. In addition, when installing Go on Windows Server, you need to ensure that the Windows Server operating system version is 64-bit, otherwise the installation will not be successful.

After downloading the installation package, double-click to open the installation program and follow the prompts to install. After installation, open the command line tool and enter the go version command. If the golang version number is output, the installation is successful.

2. Set environment variables

After the installation is complete, we need to set the golang environment variables (GOPATH and GOROOT).

GOPATH is the working directory of golang. On Windows Server, GOPATH needs to be set to a directory to store source code and library files. In order to set the GOPATH variable, you can right-click "My Computer", select "Properties" > "Advanced System Settings" > "Environment Variables" > "System Variables" > "New", type GOPATH, and then enter golang working directory. (For example, GOPATH=C:\go)

GOROOT is the installation directory of golang, which is used to store golang binary files and standard libraries. Similarly, in order to set the GOROOT variable, you can enter the GOROOT variable name and then enter the golang installation directory. (For example, GOROOT=C:\Go)

3. Configure the PATH environment variable

In order to facilitate the use of golang in the command line, you need to add the directory where the golang binary file is located to the PATH environment variable. In the "Environment Variables" window, under "System Variables", find the Path variable and add the path to the golang bin directory after the variable. (For example, C:\go\bin).

4. Verify whether the environment variable settings are correct

In order to verify whether the environment variables are correct, you need to start a command line window, enter the go env command, and check whether the output contains GOROOT and GOPATH path. If the environment variables are set correctly, the output should look like this:

set GO111MODULE= 
set GOARCH=amd64 
set GOBIN= 
set GOCACHE=C:\Users\Administrator\AppData\Local\go-build 
set GOENV=C:\Users\Administrator\AppData\Roaming\go\env 
set GOEXE=.exe 
set GOFLAGS= 
set GOHOSTARCH=amd64 
set GOHOSTOS=windows 
set GOINSECURE= 
set GONOPROXY= 
set GONOSUMDB= 
set GOOS=windows 
set GOPATH=C:\go 
set GOPRIVATE= 
set GOPROXY=https://proxy.golang.org,direct 
set GOROOT=C:\Go 
set GOSUMDB=sum.golang.org 
set GOTMPDIR= 
set GOTOOLDIR=C:\Go\pkg\tool\windows_amd64 
set GCCGO=gccgo 
set AR=ar 
set CC=gcc 
set CXX=g++ 
set CGO_ENABLED=1 
set GOMOD= 
set CGO_CFLAGS=-g -O2 
set CGO_CPPFLAGS= 
set CGO_CXXFLAGS=-g -O2 
set CGO_FFLAGS=-g -O2 
set CGO_LDFLAGS=-g -O2 
set PKG_CONFIG=pkg-config 
set GOGCCFLAGS=-m64 -mthreads -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=C:\Users\ADMINI~1\AppData\Local\Temp\go-build756411199=/tmp/go-b
uild -gno-record-gcc-switches

5. Writing, compiling and running golang programs

Finally, we can write a simple hello world Program to verify whether the method of deploying golang on winserver is successful.

Create an e:\goprojects\hello_world\hello_world.go file and write the following code:

package main

import "fmt"

func main() {
    fmt.Println("Hello, world!")
}

In the command line, enter the directory where the hello_world.go file is located and enter go build hello_world.go will generate the executable file hello_world.exe in the directory.

Finally, enter the hello_world command on the command line, and Hello, world! will be output.

So far, we have successfully deployed and run the golang program on WinServer.

In short, deploying golang on WinServer may have some initialization challenges, but by correctly setting environment variables such as GOPATH, GOROOT, and PATH, we can easily deal with these challenges and quickly run our golang program.
