Linux系统开启WIFI热点

第一步：安装create_ap

如果没有无线网卡就不要继续往下看了

项目github地址：https://github.com/oblique/create_ap
通用的安装方法
建议使用这种方式安装

git clone https://github.com/oblique/create_ap
cd create_ap
make install

第二步：使用方法

查看网卡名及使用方法请参考github主页介绍。对于不同的linux系统查看网卡的命令也有差异。
注意，运行需要root权限。
举例：来自同一WiFi接口的互联网共享：

sudo create_ap 无线网卡名 无线网卡名 热点名 热点密码

本人运行截图

[zangsheng@zangsheng-pc ~]$ sudo create_ap wlp5s0 wlp5s0 WifiForLinux password
[sudo] zangsheng 的密码：

第三步：报错及解决办法

1.查看报错信息，确认依赖是否安装好
2.wlan0不一定是你的网卡名
3.无线网卡一次只能在一个频率上工作，要么都是2.4GHz要么都是5GHz
4.Failed to initialize lock error

 sudo rm -rf /tmp/create_ap.all.lock

5.ERROR: Your adapter can not transmit to channel 149, frequency band 5GHz.

 cd create_ap
 vim create_ap

查找is_wifi_connected()

/is_wifi_connected()回车

修改为

is_wifi_connected() {
    return 1
}

重新安装一次即可
