1. 检查无线网卡驱动是否安装
1 xxx#iwconfig若打印wlan0（或其他名字）的无线网卡信息，则表明无线网卡驱动已经安装，否则要先安装无线网卡驱动方能继续。
2. 配置/etc/sysconfig/network-scripts/ifcfg-wlan0
我的配置文件内容为：
1 DEVICE=wlan0
2 HWADDR=9C:4E:36:9A:64:10
3 TYPE=Wireless
4 UUID=f017bd9c-eebf-46fc-823c-7f76cc8d5abf
5 ONBOOT=no
6 NM_CONTROLLED=yes
7 BOOTPROTO=dhcp
8 ESSID="thm"3. 安装工具wpa_supplicant
1 xxx#yum install wpa_supplicant4. 配置/etc/wpa_supplicant/wpa_supplicant.conf，写入相关ssid和对应的密码
1 xxx#wpa_passphrase thm 12345678 >> /etc/wpa_supplicant/wpa_supplicant.conf我的配置文件内容为：
1 ctrl_interface=/var/run/wpa_supplicant
2 ctrl_interface_group=wheel
3
4 network={
5 ssid="thm"
6 #psk="12345678"
7 psk=eabb3e1572789c41a1600051b1235e03c0787c88fc527f6597cd29cb5a7078225. 后台运行wpa_supplicant进程
1 xxx#wpa_supplicant -B -Dwext -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf6. 搜索无线网络
1 xxx#iwlist wlan0 scan | grep ESSID7. 连接无线网络
