树莓派无线配置，之前有写过，但是总有人搞不清楚，现在我再把3份文件保存在这里，供参考；

下面包含三种配置：

interfaces interfaces.wlan0.dhcp interfaces.wlan0.static

看其中内容：

interfaces.default

# interfaces(5) file used by ifup(8) and ifdown(8)# Please note that this file is written to be used with dhcpcd# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'# Include files from /etc/network/interfaces.d:source-directory /etc/network/interfaces.dauto loiface lo inet loopbackiface eth0 inet manualallow-hotplug wlan0iface wlan0 inet manual    wpa-conf /etc/wpa_supplicant/wpa_supplicant.confallow-hotplug wlan1iface wlan1 inet manual    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

interfaces.wlan0.dhcp

# interfaces(5) file used by ifup(8) and ifdown(8)# Please note that this file is written to be used with dhcpcd# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'# Include files from /etc/network/interfaces.d:source-directory /etc/network/interfaces.dauto loiface lo inet loopbackiface eth0 inet manual#allow-hotplug wlan0#iface wlan0 inet manual#    wpa-conf /etc/wpa_supplicant/wpa_supplicant.confauto wlan0  allow-hotplug wlan0  iface wlan0 inet dhcp          wpa-ssid "Wingspan-Working"          wpa-psk  "wingspan" allow-hotplug wlan1iface wlan1 inet manual    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

interfaces.wlan0.static

# interfaces(5) file used by ifup(8) and ifdown(8)# Please note that this file is written to be used with dhcpcd# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'# Include files from /etc/network/interfaces.d:source-directory /etc/network/interfaces.dauto loiface lo inet loopbackiface eth0 inet manual#allow-hotplug wlan0#iface wlan0 inet manual#    wpa-conf /etc/wpa_supplicant/wpa_supplicant.confauto wlan0allow-hotplug wlan0iface wlan0 inet static  wpa-ssid "Wingspan-Working"  wpa-psk "wingspan"  address 192.168.11.80  netmask 255.255.255.0  gateway 192.168.11.1allow-hotplug wlan1iface wlan1 inet manual    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

之前的方式只是一种，而且并不是很稳定，不能配置多个WIfi链接

下面的方法可以配置多个Wifi连接：

lifeccp@raspberrypi:~ $ cat /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)# Please note that this file is written to be used with dhcpcd# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'# Include files from /etc/network/interfaces.d:source-directory /etc/network/interfaces.d#auto loauto lo wlan0 wlan1iface lo inet loopbackiface eth0 inet dhcpauto wlan0allow-hotplug wlan0iface wlan0 inet dhcpwpa-conf /etc/wpa_supplicant/wpa_supplicant.conf#wpa-conf /etc/wpa.conf#iface default inet dhcp#    wpa-ssid "Wingspan-Guest"#    wpa-psk "wingspanwifi"allow-hotplug wlan1iface wlan1 inet manual#    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

文件2：

/etc/wpa_supplicant/wpa_supplicant.conf

country=GBctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdevupdate_config=1network={ssid="test"psk="12348765"}network={ssid="hao"psk="00009999"}network={ssid="WingSpan-Guest"psk="wingspanwifi"}

搜索附近可用的无线网络：

lifeccp@raspberrypi:~ $ sudo iwlist wlan0 scan | grep ESSID[sudo] password for lifeccp:                     ESSID:"HaoChuang-Guest"                    ESSID:"HaoChuang-dispaly"                    ESSID:"HaoChuang-Guest"                    ESSID:"HaoChuang-Guest"                    ESSID:"mac\xE7\x9A\x84MacBook Pro"

当然,配置的时候，如果有疑问，也可以参考其他的配置文档：

---------------补充--------------

树莓派配置无线静态IP地址

修改文件： /etc/network/interfaces，命令如下

sudo vi /etc/network/interfaces

注释掉这两行

#iface wlan0 inet dhcp #    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

并补充如下信息，（或将最后一句 iface default inet dhcp，替换成）：

iface wlan0 inet static    wpa-conf /etc/wpa_supplicant/wpa_supplicant.confaddress 192.168.21.181netmask 255.255.255.0gateway 192.168.21.1dns-nameservers 61.134.1.4

则需要两个配置文件，分别如下：

/etc/network/interfaces：

auto loiface lo inet loopbackiface eth0 inet manual#pre-up ifconfig eth0 hw ether 00:9a:9b:96:6a:7cauto eth2iface eth2 inet manualauto wlan0allow-hotplug wlan0iface wlan0 inet static    wpa-conf /etc/wpa_supplicant/wpa_supplicant.confaddress 192.168.21.181netmask 255.255.255.0gateway 192.168.21.1dns-nameservers 61.134.1.4#iface wlan0 inet dhcp #    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf#allow-hotplug wlan0#iface wlan0 inet manual#    wpa-conf /etc/wpa_supplicant/wpa_supplicant.confallow-hotplug wlan1iface wlan1 inet manual    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

/etc/wpa_supplicant/wpa_supplicant.conf：

country=GBctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdevupdate_config=1network={ ssid="WingSpan-Guest" psk="wingspanwifi"}network={  ssid="tozed-1CA8D5"  psk="691065DA"}

修改之后保存退出，然后重启网络：

sudo /etc/init.d/networking restart

即可见结果为静态IP：
