You should install Go first.

• Ubuntu & Debian based Linux

sudo apt-get install go-lang

This project is based on hazel and utils. You can get it by the command:

go get github.com/sctlee/hazel
go get github.com/sctlee/utils

Be careful, You may want to cd /path/to/example and export GOPATH=$(pwd):$GOPATH, the exec the above commands.

If you have installed Go and dependences, you can easily install the example using the following commands.

cd /path/to/example
export GOPATH=$(pwd):$GOPATH
go install example

If you have installed the example successfully, you will see the binary file example in /path/to/example/bin, you can use it as the following:

./bin/example server
# open a new bash
./bin/example client
> chatroom.join|ctName:1
> chatroom.send|msg:hello

Chatroom feature has three command: list, join, send

> chatroom.list|
> chatroom.join|ctName:1
> chatroom.send|msg:hello

User feature has three command: login, logout, setName

> user.login|username:***;password:***
> user.setName|name:hc
> user.logout|

Because db has not been supported, user's name is fake. It means you can't sign up and the name you set can't be saved.

#Docker Deployment If you have not known docker, learn it.

Pull two images, postgres and redis

docker pull postgres
docker pull redis

If you use DaoCloud Tools, you can do this:

dao pull postgres
dao pull redis

It will be extremely fast! in TianChao.

Build hazel images, hazel for (hazel)[github.com/sctlee/hazel], hazel-server for (hazel_example)(github.com/sctlee/hazel_example)

docker build -t hazel:1.1 .
docker build -t hazel-server:1.1 .

!!You should build the image after modifying the config.yml.example.

Then run three containers by three command in bash respectively.

docker run --rm --name hazel_postgres -v /Users/Secret/Codes/Projects/hazel_example/test/posgres/:/docker-entrypoint-initdb.d -e POSTGRES_USER=Secret postgres
docker run --rm --name hazel_redis redis
docker run --rm -it -p 8080:9000 --link hazel_postgres:pg --link hazel_redis:rd hazel-server:1.1

What you should notice is the flag -v, I copy the sql scripts to postgresql for init the database. See the postgres for more details.

Finially, run the hazel.

example server

You can connect the server in your host computer

example client 192.168.99.100:8080
