A distributed application for home renting

Instructions

To compile and execute the files, make sure that you include the required .jar files under lib/ in the classpath.

The below instructions are provided assuming that the workers will run on the same machine

Set the IP addresses for the workers, server, and reducer by changing the constants on java.com.homerentals.backend.BackendUtils (default is localhost)

• For Linux and Mac OS: Simply execute our script by running bash startup.sh

• For Windows:

  1. cd src/main/java
     
  2. Compile the files javac -cp ../../../lib/commons-io-2.15.1.jar;../../../lib/json-20240303.jar;. com/homerentals/**/*.java
     
  3. Reserve worker ports: java -cp ../../../lib/commons-io-2.15.1.jar;../../../lib/json-20240303.jar;. com.homerentals.backend.PortManager <NUMBER_OF_WORKERS> com/homerentals/backend/ports.list
     
  4. Start the server: java -cp ../../../lib/commons-io-2.15.1.jar;../../../lib/json-20240303.jar;. com.homerentals.backend.Server com/homerentals/backend/ports.list
     
  5. Start the workers. Run the below for as many workers as you defined above. The port should be one of the automatically generated ports inside src/main/java/com/homerentals/backend/ports.list: java -cp ../../../lib/commons-io-2.15.1.jar;../../../lib/json-20240303.jar;. com.homerentals.backend.Worker <PORT>
     
  6. Start the reducer instance: java -cp ../../../lib/commons-io-2.15.1.jar;../../../lib/json-20240303.jar;. com.homerentals.backend.Reducer <NUMBER_OF_WORKERS>
     
  7. The backend is up and running. You can connect to it by either a dummy guest console with the credentials [email protected]:guest
java -cp ../../../lib/commons-io-2.15.1.jar;../../../lib/json-20240303.jar;. com.homerentals.backend.GuestConsole
     or as the host via the host console with the credentials admin:admin
java -cp ../../../lib/commons-io-2.15.1.jar;../../../lib/json-20240303.jar;. com.homerentals.backend.
     (credentials in username:password format).
     
  8. Success! You are now connected.
