Trusterd HTTP/2 Web Server



Trusterd is a high performance HTTP/2 Web Server scripting with mruby using nghttp2 and mruby-http2. You can get HTTP/2 Web Server quickly which is high performance and customizable with mruby. The HTTP/2 server and client function are pluggable. So, you can embed these functions into your C applications.

TODO

This is a very early version, please test and report errors. Welcome pull-request.

Requirements

After reading .travis.yml, you might easy to understand the install

Quick install

Manual Build

1. Install qrintf (Optional, but recommended)

Please see qrintf-gcc

or comment out this line in build_config.rb

cc.command = ENV['CC'] || 'qrintf-gcc'

2. Install jemalloc (Optional, but recommended)

Ubuntu
sudo apt-get install libjemalloc-dev

or comment out this line in build_config.rb

linker.flags_after_libraries << '-ljemalloc'

3. Download trusterd

git clone https://github.com/trusterd/trusterd.git
cd trusterd

4. Build trusterd

make

5. Install

make install INSTALL_PREFIX=/usr/local/trusterd

6. Write config $(INSTALL_PREFIX)/conf/trusterd.conf.rb

7. Run trusterd

make start INSTALL_PREFIX=/usr/local/trusterd

or

$(INSTALL_PREFIX)/bin/trusterd $(INSTALL_PREFIX)/conf/trusterd.conf.rb

8. Check by nghttp

nghttp is a client tool for HTTP/2.

$ ${GIT_CLONE_DIR}/mruby/build/host/mrbgems/mruby-http2/nghttp2/src/nghttp -v http://127.0.0.1:8080/index.html
hello trusterd world.

Benchmarks

h2load is a benchmark tool for HTTP/2.

4 worker mode benchmark demo

500,000 requests/sec is very faster!!

4 worker mode cpu usage by top demo

trusterd worker processes use cpu resources of full core mostly.
