CentOS6.9开启自动连wifi命令记录

1、需要先安装 yum -y install wpa_supplicant

2、配置wpa_supplicant接口和驱动，执行：vi /etc/sysconfig/wpa_supplicant，按a进入插入模式，编辑如下：

|# Use the flag "-i" before each of your interfaces, like so:

|# INTERFACES="-ieth1 -iwlan0"

|INTERFACES="-iwlan0" |

|# Use the flag "-D" before each driver, like so:

|# DRIVERS="-Dwext"

|DRIVERS="-Dwext"

3、将wifi信息加入到配置文件：wpa_passphrase {wifiSSIDhere} {pwhere} >>  /etc/wpa_supplicant/wpa_supplicant.conf，后面增加新的wifi也是如此

4、配置wpa_supplicant

wpa_supplicant -B w -i wlan0 -l /etc/wpa_supplicant/suplicant.conf   或者  /wpa_supplicant.conf 目录下有两个，看哪个里面有内容

ifup wlan0

5、加入到系统启动内，开机自动连接

vim /etc/rc.d/rc.local
