树莓派安装热点分享程序create_ap
将代码clone到本地
sudo git clone https://github.com/oblique/create_ap
cd create_ap
sudo make install
安装依赖的库
sudo apt-get install util-linux procps hostapd iproute2 iw haveged dnsmasq
打开热点（此时，树莓派wifi开着，但没有连wifi）
sudo create_ap wlan0 eth0 热点名 密码
此时不出意外热点将会开启，但是会有warn，可以执行以下代码
sudo create_ap --no-virt wlan0 eth0 m热点名 热点
以服务方式启动，执行开机自启
复制代码
#1.修改服务配置,添加--no-virt参数
sudo vi /usr/lib/systemd/system/create_ap.service
# 将
ExecStart=/usr/bin/create_ap --config /etc/create_ap.conf
# 修改为 
ExecStart=/usr/bin/create_ap --no-virt --config /etc/create_ap.conf

#2.默认配置文件/etc/create_ap.conf,将下面两横改为自己的ssid和密码即可,修改自己的dhcp网关
sudo vi /etc/create_ap.conf
#　将
GATEWAY=10.0.0.1
SSID=MyAccessPoint
PASSPHRASE=12345678 
#　修改为
GATEWAY=192.168.123.1
SID=dzxj
PASSPHRASE=11111111

# 启动一个服务：
systemctl start create_ap.service
# 关闭一个服务：
systemctl stop create_ap.service
# 重启一个服务：
systemctl restart create_ap.service
# 显示一个服务的状态：
systemctl status create_ap.service
# 在开机时启用一个服务：
systemctl enable create_ap.service
# 在开机时禁用一个服务：
systemctl disable create_ap.service
# 查看服务是否开机启动：
systemctl is-enabled create_ap.service
