hello friends , am Vasu Birla and Today we will deploy Python App.. in previous post we have deployed NODE js app on 0.0.0.0 (your server IP) and acess it using http://0.0.0.0/   Now  If you want to deploy a Python app separately on the same server, in the /root/demo directory, and access it using http://0.0.0.0/demo,  you can use Apache2 and mod_wsgi to host the Python app.   Additionally, you can configure Apache2 to proxy the requests for the   /demo path to your Python app without affecting the Node.js app hosted at the root.   First of all  put your python project folder on root location of server , using putty with cloning git repo or using FTP server and direct paste folder (in previous post we aleady discussed it)   lets suppose your folder name is demo .. location would be  /root/demo   install necessery things to support your python app .  like pip install or django ..etc     as well install in virtual enviorment also ..       -> python3 -m venv venv        -> source v

     hello friens , This is Vasu Birla , in previous post we have seen the deployement of NodeJS app on AWS instance server instance but AWS server is expensive than other servers . SO today we will use simple Ubuntu server for making Live out Project using Apache2 . At the end you will be abe to access your NodeJS app using server IP address from anywhere  .. 1.  Login to your server using SSH terminal . (in AWS part i already explained how to do this )     -> Open your putty in hostname put your server IP -      login with ssh username ->root and password     (if you dont have root username and pass ask your      provider or reset it from cpanel or hosting panel ) 2. after login - on terminal you can Put your project anywhere.     There are two ways to put your project folder on server location     (i) - > using Github - (very popular and easy to track your everyday code changes to your project folder)             you can push your entire project folder to git-hub and and

  hello coders , Am Vasu Birla and today we will learn how to deploy Nodejs or any App on AWS (Amazon Web Service ); 1.  Log in to AWS account 2.  Select EC2 service in Services section 3. Create / Launch Instance  (select your Instance Type - Ubuntu or choose your own) 4. After Launching Instance open it and copy public IP address 5. Open Putty App on your local machine 6. in Host name give host name - (it can be given by two ways )     -  ec2.user@0.0.0.0  (use your instance public ip instead of 0.0.0.0)                  or     -   ec2-0-0-0-0.ap-southeast-1.compute.amazonaws.com 7. also in putty app go to connection tab -> SSH -> Auth -> Credensials -> Browse and open your key pari (.ppk or .pem file) 8. if you succeced if previous step terminal will be open -   run command  'ls'  it will show nothing     because we didn't put our project folder here . 9. now on your local machine install filezilla or winSCP .... 10. Open Your WinSiP -  create new site ->
