Implementation with Python 3. Implemented using this GitHub repo. Added features:

• Authentication of Username and Password. Username and password stored in MySQL server, and password stored using MD5 encryption.
• Added file admin.py for adding, creating and listing users.
• Ported to Python3

1. Set Up
2. Running
3. Extras

• Setting up Database:

  • Set up a MySQL <user_name> and <password>.
  • Create a database in MySQL. create database <db_name>
  • Import the database file in the repository. mysql -u <username> -p <db_name> < dump_file.sql .

• Installing Requirements

  • pip3 install -r requirements.txt

• Admin Functions

  • python3 admin.py to add, delete or list users

• Running sequence of Servers

  • The sequence for running the servers are as follows: Primary Backup Server --> Master Server --> Chunks Server
  • python3 primary_BackUp_Server.py
  • python3 Master_Server.py
  • python3 Chunks.py

• Running Client

  • The Client Node would be able to perform the functions of: download (get), upload (put), remove (delete) and list the current files in the cloud server
  • Upload : python3 Client.py put <destination_file> <src_file>
  • Download : python3 Client.py get <destination_file>. This will give the output of the data stored in the file. To store it in our local directory, pipe it into another file: python3 Client.py get <destination_file> | tee src_file
  • Delete : python3 Client.py <destination_file>
  • List : python3 Client.py list

• The directory for the Google Filesystem would be ~/ of each chunk server.
• Each of the 4 operation would require the authentication of user.
• The database and chunk size can be defined in the GFS.conf
