树莓派无线中继正确姿势

可乐丸子

首先在树莓派上插入USB无线网卡，确保驱动正常，然后将无线网卡的局域网IP改成不同于无线路由器网段的IP，输入如下命令开始修改
sudo vi  /etc/network/interfaces修改成像下面的样子allow-hotplug wlan0iface wlan0 inet staticaddress 192.168.42.1netmask 255.255.255.0#iface wlan0 inet manual#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf#iface default inet dhcp安装DHCP服务端并修改配置文件sudo apt-get install isc-dhcp-serversudo vi /etc/dhcp/dhcpd.conf去掉authoritative一行前面的#号和下面两行前面的#号option domain-name "example.org";option domain-name-servers ns1.example.org, ns2.example.org;接着在最后一行后面加入下面代码subnet 192.168.42.0 netmask 255.255.255.0 { range 192.168.42.10 192.168.42.50; option broadcast-address 192.168.42.255; option routers 192.168.42.1; default-lease-time 600; max-lease-time 7200; option domain-name "local"; option domain-name-servers 8.8.8.8, 8.8.4.4;}然后按ESC键输入:wq保存修改
接着修改下面配置文件
sudo vi /etc/default/isc-dhcp-server接口修改为如下wlan0INTERFACES="wlan0"安装AP热点程序和修改配置文件sudo apt-get install hostapdsudo vi /etc/hostapd/hostapd.conf创建无线热点的SSID和密码interface=wlan0driver=nl80211#driver=rtl871xdrvssid=RPI-WIFIhw_mode=gchannel=6macaddr_acl=0auth_algs=1ignore_broadcast_ssid=0wpa=2wpa_passphrase=raspberrypiwpa_key_mgmt=WPA-PSKwpa_pairwise=TKIPrsn_pairwise=CCMP上面创建的无线热点名称为RPI-WIFI，无线密码为raspberrypi
修改守护程序的配置文件
sudo vi /etc/default/hostapd找到DAEMON_CONF一行，修改如下DAEMON_CONF="/etc/hostapd/hostapd.conf"重启然后就应该可以用手机发现树莓派的热点RPI-WIFI了
