Client/server
This is a simple project on using sockets for interprocess communication. There are three C linux servers available for usage and you can connect to them through a proxy with N clients.
Customer server
Food server
Drink server
Each server uses a different technique to handle passing information from one process to another and contains a unique database for create and read operations. The customer server uses FIFO, the next one PIPE and lastly shared memory with POSIX semaphore. The proxy redirects the clients menssage to the correct server depending on the size of the object.
Getting Started
To use these servers follow the instructions below.
Prerequisites
For the proper functioning of this code it is necessary to use a GNU / Unix system, in addition the following programs must be installed.
Python 2.7
GCC
Usage
To run the servers and proxy you must first compile all of them using make.
make
Then, open a different terminal for each command line:
./serverCustomer.out
./serverFood.out
./serverDrink.out
./proxy.out
Finally, for each client open a new terminal and run:
python2.7 client.py
