Create a WiFi hotspot using an open source project on GitHub:
https://github.com/oblique/create_ap
Specifically, the operation on the Raspberry Pi is as follows:
#将代码copy到本地,安装
git clone https://github.com/oblique/create_ap
cd create_ap
make install
#安装依赖的库
apt-get install util-linux procps hostapd iproute2 iw haveged dnsmasq
#创建WiFi热点(GitHub上有多种方式创建,可以查找自己需要的那种)
sudo create_ap wlan0 eth0 热点名 密码
#开机启动
将sudo create_ap wlan0 eth0 热点名 密码 添加到/etc/rc.local当中,即可开机启动
