setup git on an existing project in AWS EC2 instance

Need to use version control in one of the old project which resides in Amazon EC2 instance. Steps performed:

/www/box/

1. Installed GIT on the server and initialised the folder /box/

   git init
   
   

2. Cloned the project in local computer

3. Changed a file and tried to push but received error

   git push origin master
   Error: Updating the current branch in a non bare repository is denied
   
   

4. Then created another repo folder on server and used --bare tag to initialize

   /www/repos/
   git init --bare
   
   

5. PUSH command works well on this repository

6. Then added another REMOTE URL to the old project location git remote add production ssh:---/www/box/

Questions:

• git push gives me the same error when pushing on to the production repo. How do I push to this production repo?

  git push production master
  Error: .... non bare repository is denied
  
  

• found lots of tutorial using HOOKS, still confused if using HOOKS is a normal method to push in GIT
