Quickstart

From Source

You need a complier with C++11 support like GCC 4.7 (or later) or Clang.

Download a source release, then:

tar xzf kids-VERSION.tar.gz
cd kids-VERSION
./configure
make
make test  # optional
make install

By default, it will be installed to /usr/local/bin/kids. You can use the --prefix option to specify the installation location. Run ./configure --help for more config options.

Kids comes with some sample config files in samples/, after building, simply run:

kids -c samples/dev.conf

Because kids uses redis protocol, you can use redis-cli to play with it, open another terminal:

$ redis-cli -p 3888
$ 127.0.0.1:3388> PSUBSCRIBE *

In yet another terminal:

$ redis-cli -p 3388
$ 127.0.0.1:3388> PUBLISH kids.testtopic message

redis-cli needs redis to be installed. On Mac, you can run brew install redis to install it. On Linux, run sudo apt-get install redis-tools

Run kids --help for more running options.

Do the following:

git clone https://github.com/zhihu/kids.git
cd kids
cp samples/dev.conf debian/kids.conf
docker build -t zhihu/kids .
