首先还是更新下系统

sudo apt-get update && sudo apt-get dist-upgrade -y

然后安装一些必要的软件

sudo apt-get install -y git hostapd haveged dnsmasq

这里使用create_ap来快速创建，所以先要安装下create_ap

新建一个目录Github

mkdir Github && cd Github

把create_ap源码克隆回来，查看README.md可以发现关于依赖的一些东西

## Dependencies

### General

* bash (to run this script)

* util-linux (for getopt)

* procps or procps-ng

* hostapd

* iproute2

* iw

* iwconfig (you only need this if 'iw' can not recognize your adapter)

* haveged (optional)

### For 'NATed' or 'None' Internet sharing method

* dnsmasq

* iptables

执行以下命令克隆

git clone https://github.com/oblique/create_ap.git

切换到相应目录进行编译安装

cd create_ap

make install

然后尝试创建wifi，这里给出了很多种创建的方案

## Installation

### Generic

git clone https://github.com/oblique/create_ap

cd create_ap

make install

### ArchLinux (AUR)

yaourt -S create_ap

### Gentoo

emerge layman

layman -f -a jorgicio

emerge net-wireless/create_ap

## Examples

### No passphrase (open network):

create_ap wlan0 eth0 MyAccessPoint

### WPA + WPA2 passphrase:

create_ap wlan0 eth0 MyAccessPoint MyPassPhrase

### AP without Internet sharing:

create_ap -n wlan0 MyAccessPoint MyPassPhrase

### Bridged Internet sharing:

create_ap -m bridge wlan0 eth0 MyAccessPoint MyPassPhrase

### Bridged Internet sharing (pre-configured bridge interface):

create_ap -m bridge wlan0 br0 MyAccessPoint MyPassPhrase

### Internet sharing from the same WiFi interface:

create_ap wlan0 wlan0 MyAccessPoint MyPassPhrase

### Choose a different WiFi adapter driver

create_ap --driver rtl871xdrv wlan0 eth0 MyAccessPoint MyPassPhrase

### No passphrase (open network) using pipe:

echo -e "MyAccessPoint" | create_ap wlan0 eth0

### WPA + WPA2 passphrase using pipe:

echo -e "MyAccessPoint\nMyPassPhrase" | create_ap wlan0 eth0

### Enable IEEE 802.11n

create_ap --ieee80211n --ht_capab '[HT40+]' wlan0 eth0 MyAccessPoint MyPassPhrase

### Client Isolation:

create_ap --isolate-clients wlan0 eth0 MyAccessPoint MyPassPhrase

## Systemd service

Using the persistent [systemd](https://wiki.archlinux.org/index.php/systemd#Basic_systemctl_usage) service

### Start service immediately:

systemctl start create_ap

### Start on boot:

systemctl enable create_ap

先执行iw命令看下自己的网卡名称，我这里无线网卡显示的是wlx085700bd345b，有线网卡是enp0s3

sudo create_ap wlx085700bd345b enp0s3 @Freewifi --no-virt

这个模式是比较常用的模式，在无线网卡上创建一个热点，使用另外一个网卡共享网络给无线网卡达到联网的目的。--no-virt 参数表示不创建虚拟接口

如果执行之后显示 ERROR: Your adapter does not support AP (master) mode 基本上没戏，因为网卡不支持AP模式

执行之后发现报错

根据错误信息发现wlx085700bd345b: AP-DISABLED，这句的意思是网卡的AP模式不可用，这个时候可以使用官方提供的另外一种方案

sudo create_ap --driver rtl871xdrv wlx085700bd345b enp0s3 @Freewifi --no-virt

这种方式是加载一个不同的驱动，继续执行发现依然报错

Config dir: /tmp/create_ap.wlx085700bd345b.conf.xLE76fDe

提示不知道rtl871xdrv这个驱动，谷歌一下发现hostapd原版本并不支持RTL8188EUS的驱动，所以需要使用修改版的hostapd，这里先把原来的hostapd卸载

sudo apt-get remove hostapd -y

然后git回来修改好的hostapd源码

git clone https://github.com/christianeisendle/hostapd_rtl871xdrv

然后切换到对应目录编译安装

cd hostapd_rtl871xdrv/hostapd

make

sudo make install

然后继续执行

sudo create_ap --driver rtl871xdrv wlx085700bd345b enp0s3 @Freewifi --no-virt

执行成功显示这样的

手机获取到的IP地址是192.168.12.×网段的，这个可以根据自己的需要修改，接下来测试记录http请求，我写了个脚本在这 https://github.com/kbdancer/snifferPanel

git回来之后执行

python sniff.py wlx085700bd345b就可以把http请求记录到数据库了，当然前提是你已经安装了脚本所需要的一些模块

最后放个图吧

终端显示http请求

sqlite3记录http请求
