ubuntu用USB无线网卡搭建facebook atc环境

环境：ATC是FaceBook开源的移动网络测试工具Augmented Traffic Control（ATC），能够方便的让我们模拟各种网络环境进行测试。
准备：
1：ubuntu16.04、usb无线网卡(一定要linux免驱，一定要用5G频段，2.4G频段的网卡被污染严重，开启后也基本无法使用)，本地有线网络联网

此时确定安装成功，且没有报错
6：修改hostapd配置文件

:~# vim  /etc/hostapd/hostapd.conf
添加如下内容
interface=wlx1cbfce3b6370 //无线网卡名称，可以通过ifconfig查看到
driver=nl80211
ssid=autotest  //wifi名字
channel=10
hw_mode=g
macaddr_acl=0
auth_algs=3
wpa=2
wpa_passphrase=12345678 //密码
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP
rsn_pairwise=TKIP CCMP

7：启动hostapd

root@k-virtual-machine:~# nmcli radio wifi off
root@k-virtual-machine:~# rfkill unblock wlan
root@k-virtual-machine:~# killall hostapd
hostapd：没有发现操作
root@k-virtual-machine:~# hostapd -B /etc/hostapd/hostapd.conf

8：配置dhcpd

:~# vim /etc/dhcp/dhcpd.conf
添加到文件尾
subnet 192.168.0.0 netmask 255.255.255.0
    {
        range 192.168.0.2 192.168.0.10;
        option routers 192.168.0.1;
        option domain-name-servers 192.168.239.2;//填写上一步查询到的dns
    }

9：配置无线网卡的出口ip

:~# ifconfig wlx1cbfce3b6370 192.168.0.1 netmask 255.255.255.0

10：启动dhcp

# mkdir /var/run/dhcp-server
# touch /var/run/dhcp-server/dhcpd.pid
# chmod 777 /var/run/dhcp-server/dhcpd.pid

11：修改ip转发

# vim /etc/sysctl.conf
取消这一行的注释：
net.ipv4.ip_forward= 1
然后执行使之立即生效
# sudo sysctl -p
# iptables -t nat -A POSTROUTING -o ens33 -j MASQUERADE
-------------------------------------------------
# sudo iptables -F
# sudo iptables -X 
# sudo iptables -t nat -A POSTROUTING -o ens33 -j MASQUERADE 
# sudo iptables -A FORWARD -i ens33 -o wlx1cbfce3b6370 -m state --state RELATED,ESTABLISHED -j ACCEPT
# sudo iptables -A FORWARD -i wlx1cbfce3b6370 -o ens33 -j ACCEPT

12：升级pip

:~# pip install --upgrade pip

13：下载atc源码

# git clone https://github.com/facebook/augmented-traffic-control.git
# sudo pip install atc_thrift atcd django-atc-api django-atc-demo-ui django-atc-profile-storage
但是这样安装django的版本不一定是1.10的，（python -m django --version,查看安装的版本）
# sudo pip uninstall django
# sudo pip install django==1.10

14：创建工程目录

:~# cd augmented-traffic-control/
