it's a simple Redis database with c++
this project's purpose is for training C++ this is based on "build your own Redis with c\c++" book. the link to this book is this: https://build-your-own.org/
I'm using codes of this book. there are only some minor changes in codes. but the real base is on this book.
- config file: you can change IP address, port number and number of threads in server. we use a json file as config file in /etc/redis path. a sample config file is in directory of server. you should only copy it in /etc/redis/config.json.
- authentication: you cannot use any of the commands without authentication. for authentication you shoud run the client command with "auth" command. for example:
./redis-client auth USERNAME PASSWORD
for now, you can authenticate with two users.
| username | password |
|---|---|
| ahmad | 123 |
| abbas | 123 |
but in future, it will change and clients will be available from file. authentication here means authentication for IP address. In other words, your IP address is your representor. If you do not work for five minutes, your authentication will be expired and you should authenticate again.
- take a snapshot: you can use write command to take a snapshot of all keys inside your table. this command gets a path and write the table on a file in server machine. if your given file is not existed, an error will be raised and inform client that the file does not exists. otherwise, it will write all the keys and their values in csv form.
the server only has one pre-request for build and it is rapid-json. rapidjson is a famous library in c++ for parsing json files.
to install it on debian and ubuntu, you should run the following command
sudo apt install rapidjson-dev
to compile server or client, you should go to the respective directory and run the following commands
mkdir build
cd build
cmake ..
make
cuation: I'm still writing these codes. hence, maybe there are some times that my code has some problems.
