Nebula is an event-driven TCP protocol network framework developed in C++ language. It supports multiple application layer communication protocols including proto3, http, https, and websocket. The purpose of developing the Nebula framework is to provide a fast and high-performance distributed service cluster based on C++.
Nebula can be used as a single high-performance TCP server, but building a cluster based on Nebula will be truly reflect its value. In order to build distributed service clusters quickly, Nebula Bootstrap cluster solutions including various types of services have been developed.

Nebula was developed with C++11/C++14 standard, and the compiler must fully support C++11(some C++14 features are replaced by C++11 standard when encountering a lower version of the compiler).
Nebula was builded passing with gcc6.4 on centos6.5(upgrade binutils to 2.22 or later) and centos7.4.
We provides NebulaBootstrap, which allows developers to build and deploy Nebula quickly. Nebula will be a framework that be widely used. A distributed solution based on NebulaBootstrap will make it easy to develop micro-service applications in C++.
You must ensure that your system is installed with a fully C++11 compiler before you build, and all dependencies will be automatically resolved in the following build steps.
build step：
-
wget https://github.com/Bwar/NebulaBootstrap/archive/master.zip
-
unzip master.zip; rm master.zip; mv NebulaBootstrap-master NebulaBootstrap
-
cd NebulaBootstrap
-
chmod u+x deploy.sh
-
./deploy.sh
Run deploy.sh, the NebulaBootstrap distributed services were build completed. The reliance of Nebula was also automatically downloaded and compiled by deploy from the Internet before the construction of Nebula. The deploy path as follows:
-
NebulaBootstrap
- bin server bin location。
- build build path，created by deploy.sh, if you do not need to build again, just delete it.(optional)。
- conf configuration path.
- data application data path. e.g. Nebio which is a data collect and real-time analysis application, write it's data to this path (optional).
- lib library path.
- log program logs path.
- plugins plugins path.
- logic plugins for logic server(optional).
- script script path. deploy.sh, startup.sh and shutdown.sh were depend on this path.
- temp temp file path(optional).
- configure.sh run configure.sh for a simple configuration when deploy for the first time.
- deploy.sh auto build and deploy.
- shutdown.sh shutdown one or more server.
- startup.sh startup one or more server.
- README_cn.md
- README.md
build completed, you can start the server:
./configure.sh
./startup.s
The server should have started successfully now, startup.sh will print the server that had been started, If not, check logs for reason. Notice that the default configuration file of Nebula limits the number of connections per IP in a period. If you have a large amount of testing, you should check the configuration limit. If the server has been successfully started, testing with postman or curl.
# testing start with NebulaInterface only.
curl -H "Content-Type:application/json" -X POST -d '{"name": "Nebula", "address":"https://github.com/Bwar/Nebula"}' http://${your_ip}:16003/hello
# testing start with NebulaInterface,NebulaLogic and NebulaBeacon.
curl -H "Content-Type:application/json" -X POST -d '{"name": "Nebula", "address":"https://github.com/Bwar/Nebula"}' http://${your_ip}:16003/hello_nebula
A simple testing can be start with a NebulaInterface only, and also can be start with NebulaBootstrap. NebulaBootstrap provided the a cluster HelloWorld, the testing will launch NebulaBeacon, NebulaInterface and NebulaLogic. This is a diagram of the cluster architecture:
