1.git clone https://github.com/oblique/create_ap.git
2.cd create_ap
3.sudo make install就这样安装好了
4.接下来安装依赖库sudo apt-get install util-linux procps hostapd iproute2 iw haveged dnsmasq
5.就这么简单几个命令就能安装好全部环境
6.接下来保证你的网线插在pi3上并且能上网就行了。输入下面的命令启动无线AP：
sudo create_ap wlan0 eth0 热点名 密码
接下来就去打开手机wifi看看有没有上面命令中设置的热点名吧，有的话输入密码即可连接上，enjoy your PI3 wireless AP！
可以把上述的启动命令添加到/etc/rc.local就可以开机自启动了。
是不是很简单，这个AP的局域网无线传输速度居然比我原来那个老AP还快一倍，也算是惊喜了，从此我的树莓派3又增加了一个功能。
