## Design
|
|
|
|
|
|
|
|
|
|
## QuickStart
|
|
|
|
Download binary packeges for linux, mac and freebsd from [http://emqtt.io/downloads](http://emqtt.io/downloads).
|
|
|
|
For example:
|
|
|
|
```sh
|
|
tar xvf emqttd-ubuntu64-0.7.0-alpha.tgz && cd emqttd
|
|
|
|
# start console
|
|
./bin/emqttd console
|
|
|
|
# start as daemon
|
|
./bin/emqttd start
|
|
|
|
# check status
|
|
./bin/emqttd_ctl status
|
|
|
|
# stop
|
|
./bin/emqttd stop
|
|
```
|
|
|
|
Build from source:
|
|
|
|
```
|
|
git clone https://github.com/emqtt/emqttd.git
|
|
|
|
cd emqttd && make && make dist
|
|
```
|
|
|
|
|
|
## GetStarted
|
|
|
|
Read [emqtt wiki](https://github.com/emqtt/emqttd/wiki) for detailed installation and configuration guide.
|
|
|
|
|
|
## Benchmark
|
|
|
|
Benchmark 0.6.1-alpha on a ubuntu/14.04 server with 8 cores, 32G memory from QingCloud:
|
|
|
|
200K+ Connections, 200K+ Topics, 20K+ In/Out Messages/sec, 20Mbps+ In/Out with 8G Memory, 50%CPU/core
