# Note: After entering kicked Below, you can continue to enter the contents of the file, here directly copy the contents of the file below to main.js this file inside. Ctrl + C to save and exit.
CAT >> main.js 

# main.js file content 
var HTTP = the require ( ' HTTP ' ); 
 
http.createServer ( function (Request, Response) { 
 
    // HTTP headers are sent 
     // HTTP status values: 200 is: the OK
     // content type: text / Plain 
    response.writeHead ( 200 is , { ' the content-the type ' : ' text / Plain ' }); 
 
    // send a response "the Hello World" 
    Response.End ( 'World hello \ n- ' ); 
.}) The listen ( 8888 ); 
 
// print terminal following information 
the console.log ( ' Server running AT http://127.0.0.1:8888/ ' );

After creating main.js complete, execute the following command 

main.js the Node
