- main: Latest content, with a simple clerk implemented.
- rpc：Related content based on the muduo and RPC framework.
- raft_DB：A key-value storage database based on Raft, mainly used for observing the election process.
- muduo
- boost
- protoc
- clang-format（optional）
Installation Instructions
- protoc，The local version used is 3.12.4. For Ubuntu 22, you can install it using sudo apt-get install protobuf-compiler libprotobuf-dev, which should default to this version.
- boost，Install it using sudo apt-get install libboost-dev libboost-test-dev libboost-all-dev.
mkdir cmake-build-debug
cd cmake-build-debug
cmake ..
make
After this, the corresponding executable files will be generated in the bin directory:
- consumer
- provider Run them as needed, ensuring that you start the provider first, followed by the consumer. The reason is simple: the RPC service must be provided before it can be invoked.
mkdir cmake-build-debug
cd cmake-build-debug
cmake..
make
After this, the corresponding executable files will be generated in the bin directory. To run, execute:
// make sure you in bin directory ,and this has a test.conf file
raftCoreRun -n 3 -f test.conf
It is recommended to use a one-click run feature via CLion or CLion Nova; you can simply click the button to execute:
Once running successfully, the command line should display Raft operation output similar to the following:：

After starting the Raft cluster, simply run callerMain.
- Complete Raft cluster functionality
- Remove redundant libraries: muduo, boost
- Code refactoring and optimization
- code format
