Webe

Introduction

Webe is a web server. I wrote it to hand it in as homework... It uses event loop with non-blocking IO and epoll.

How to Build

# For Debian 9 with gcc-6.3.0
$ apt install -y libboost-filesystem-dev
$ git clone https://github.com/Fugoes/Webe.git
$ cd Webe
$ mkdir cmake
$ cd cmake
$ cmake ..
$ make

To get release version which run much faster, use cmake -DCMAKE_BUILD_TYPE=Release .. instead of cmake ...

How to Use

$ cd Webe/cmake
$ ./webectl
Usage: webectl load-module <module>
       webectl unload-module <module>
       webectl list-server
       webectl stop-server
       webectl start-server <processes> [ OPTIONS ]
where  OPTIONS = { -a <address> | -p <port> }

You could directly run ./webed instead. By default, it will load all modules.

Demo

$ cd Webe/cmake
$ ln -s ../example/static static
$ ./webectl start-server 4 -a 0.0.0.0 -p 8080
$ ./webectl list-server
        PID
 ----------
       1906
       1907
       1905
       1908

Now browse http://127.0.0.1:8080/info.

To unload some module:

$ ./webectl unload-module info

Now browse http://127.0.0.1:8080/info, it shall be 404 Not Found.

To stop all server:

$ ./webectl stop-server
        PID  STATUS
 ---------- -------
       1906 STOPPED
       1907 STOPPED
       1905 STOPPED
       1908 STOPPED

You could also do some benchmark with ab from Apache2:

$ ab -k -n 1000000 -c 100 http://127.0.0.1:8080/static/nice.css
...
Concurrency Level:      100

This result is tested with an i5 4210H CPU.
