# F-Stack Binary Release Quick Start

## How to use

Before you start to use f-stack-binary-release package, please make sure you: 
- have access to the internet
- have at least one NIC up
- have root permission
- meet all other requirements of dpdk

```sh
$ sudo -i
$ tar zxf f-stack-binary-release.tar.gz
$ cd f-stack-binary-release/scripts
# set_env.sh will offload the NIC, if you only have one NIC, the following three commands must run in a script
$ ./set_env.sh dev_name
$ ./run_app.sh [app_name]
$ ./config_veth0.sh
```

- dev_name is the name of your NIC, you can see it with *ifconfig* or *ip addr* command
- app_name is the name of application you want to run, now we support 'nginx' and 'redis'. If you do not add any argument, it will run a helloworld example, you can use it to test whether the envrionment is setup correctly.
- All the scripts should run with root permission

## Supported Linux releases

 The f-stack-binary-release package has supported several frequent used linux releases, you can use f-stack applications directly on these releases. What should be paid attention to is that f-stack uses linux kernel modules, so if you have different kernel versions in your machine, you could not use this f-stack-quick-start package and need to compile f-stack by yourself. Here is the list of linux releases this package support now:
