How to Install Trusted-CGI on FreeBSD Latest?

Trusted-CGI is a tool that allows the creation of secure CGI scripts in Golang. In this tutorial, we will show you how to install Trusted-CGI on FreeBSD.

Prerequisites

Before you start, you will need the following:

• A FreeBSD machine
• A user account with superuser privileges
• An internet connection

Step 1: Install Golang

Trusted-CGI is written in Golang, so you will need to install the Go programming language.

1. Open the terminal and log in to your FreeBSD machine as a superuser.

2. Run the following command to install the Go programming language:

pkg install go

3. Check that Go is installed correctly by running the following command:

go version

You should see the version number of your Go installation.

Step 2: Install Trusted-CGI

1. Open the terminal and navigate to the directory where you want to install Trusted-CGI.

2. Clone the Trusted-CGI repository from Github by running the following command:

git clone https://github.com/reddec/trusted-cgi.git

3. Navigate to the Trusted-CGI directory by running the following command:

cd trusted-cgi

4. Build Trusted-CGI by running the following command:

go build cmd/trusted-cgi/main.go

This will compile and build the Trusted-CGI executable.

5. Move the Trusted-CGI executable to the /usr/local/bin directory by running the following command:

sudo mv main /usr/local/bin/trusted-cgi

6. Check that Trusted-CGI is installed correctly by running the following command:

trusted-cgi --help

You should see the Trusted-CGI help menu.

Step 3: Testing Trusted-CGI

Now that you have installed Trusted-CGI, you can test it by creating a simple CGI script.

1. Create a new directory for your script by running the following command:

mkdir cgi-bin

2. Navigate to the cgi-bin directory by running the following command:

cd cgi-bin

3. Create a new file named hello.go by running the following command:

nano hello.go

4. Copy and paste the following code into the hello.go file:

package main

import (
   "fmt"
   "net/http"
)

func main() {
   http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
       fmt.Fprintf(w, "Hello, World!")
   })

   err := http.ListenAndServe(":8080", nil)
   if err != nil {
       panic(err)
   }
}

This will create a simple CGI script that will display the message "Hello, World!" when accessed.

5. Save and exit the hello.go file.

6. Make the hello.go file executable by running the following command:

chmod +x hello.go

7. Run the hello.go script by running the following command:

trusted-cgi -work-dir=. ./hello.go

8. Open a web browser and go to http://localhost:8080/cgi-bin/hello.go.

You should see the message "Hello, World!" displayed on your screen, indicating that your CGI script is working correctly.

Conclusion

Congratulations! You have successfully installed Trusted-CGI on your FreeBSD machine and tested it by creating a simple CGI script. You can now use Trusted-CGI to create secure CGI scripts for your applications.
