树莓派2B 配置无线wifi dhcp 静态IP，同时开机启动

环境：2015-05-05-raspbian-wheezy版本

1.修改vi /etc/network/interfaces
添加一下语句，删除其他跟wlan0相关的code

allow-hotplug wlan0
iface wlan0 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

2.vi /etc/wpa_supplicant/wpa_supplicant.conf
修改wifi账号和密码

country=CN
network={
        ssid="xxx"
        psk="xxx"
        key_mgmt=WPA-PSK
}

3.配置dhcp静态ip : vi /etc/dhcpcd.conf

interface wlan0
static ip_address=192.168.0.88/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.1 192.168.1.1 8.8.8.8 8.8.4.4

4.添加到开机启动

vi /etc/rc.local
ifup wlan0
exit 0

5.重启看效果
reboot
