CentOS-6.4無線上網命令行配置

   待連接的WIFI的ssid為“thm”,密碼為12345678,認證方式為WPA2-PSK

  1. 檢查無線網卡驅動是否安裝

  1 xxx#iwconfig

  若打印wlan0(或其他名字)的無線網卡信息,則表明無線網卡驅動已經安裝,否則要先安裝無線網卡驅動方能繼續。

  2. 配置/etc/sysconfig/network-scripts/ifcfg-wlan0

  我的配置文件內容為:

  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. 安裝工具wpa_supplicant

  1 xxx#yum install wpa_supplicant

  4. 配置/etc/wpa_supplicant/wpa_supplicant.conf,寫入相關ssid和對應的密碼

  1 xxx#wpa_passphrase thm 12345678 >> /etc/wpa_supplicant/wpa_supplicant.conf

  我的配置文件內容為:

  1 ctrl_interface=/var/run/wpa_supplicant

  2 ctrl_interface_group=wheel

  3

  4 network={

  5 ssid="thm"

  6 #psk="12345678"

  7 psk=eabb3e1572789c41a1600051b1235e03c0787c88fc527f6597cd29cb5a707822

  5. 後台運行wpa_supplicant進程

  1 xxx#wpa_supplicant -B -Dwext -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

  6. 搜索無線網絡

  1 xxx#iwlist wlan0 scan | grep ESSID

  7. 連接無線網絡

  1 xxx#iwconfig wlan0 essid "thm"

  8. dhcp方式獲取ip

  1 xxx#dhclient wlan0

  9. 測試網絡是否聯通
