1. System Environment Preparation

#关闭selinux

Sed-i ' s/selinux=enforcing/selinux=disabled/'/etc/selinux/config

Setenforce 0

#安装一大堆库

Yum-y Install Libtool zlib* glib*

2. Enter the installation

[[email protected] linux]# ls

android_ref_codes_jb_4.2 document install.sh Readme.txt Wifi_direct_user_interface WPA_SUPPLICANT_HOSTAPD

android_ref_codes_kk_4.4 driver Mp_tools releasenotes.pdf wireless_tools

[Email protected] linux]# chmod +x install.sh

[Email protected] linux]# ./install.sh

... ...

Make: * * */lib/modules/3.10.0-327.el7.x86_64/build: No file or directory

... ...

Solution Ideas:

Switch to its directory:

[Email protected] linux]# cd/lib/modules/3.10.0-

3.10.0-327.el7.x86_64/3.10.0-514.2.2.el7.x86_64/

[Email protected] linux]# cd/lib/modules/3.10.0-514.2.2.el7.x86_64/

[[email protected] 3.10.0-514.2.2.el7.x86_64]# ls

Build Modules.alias modules.builtin modules.dep.bin modules.modesetting MODULES.SOFTDEP Source Weak-u Pdates

Extra Modules.alias.bin modules.builtin.bin modules.devname modules.networking modules.symbols Updates

Kernel modules.block modules.dep modules.drm modules.order modules.symbols.bin vdso

[[email protected] 3.10.0-514.2.2.el7.x86_64]# LS-LHD build

lrwxrwxrwx 1 root root 42 December 10:19 Build-/usr/src/kernels/3.10.0-514.2.2.el7.x86_64

Workaround:

[Email protected] linux]# ln-s/usr/src/kernels/3.10.0-514.2.2.el7.x86_64/lib/modules/3.10.0-327.el7.x86_64/ Build

And then execute it again.

[Email protected] linux]# ./install.sh

Everything goes well, then look at the network card, here save space, will not show all,

[[Email protected] linux]# IP link

... ...

11:ENP0S20U2: <NO-CARRIER,BROADCAST,MULTICAST,UP> MTU Qdisc MQ State down mode dormant Qlen 1000

Link/ether e8:4e:06: 40:cc:10 BRD FF:FF:FF:FF:FF:FF

... ...

If it is the above image in the model of the network card, you can compare the MAC address of the network card (e8:4e:06) This is the unique logo of each vendor is planned by a specific organization, and then you can confirm that this is the wireless card you need, I did not know at the beginning of this installation is good, until I installed the second time ...

3. Scan the surrounding WiFi signal

Again into the drive directory provided by the disc

[[email protected] linux]# ls

android_ref_codes_jb_4.2 document install.sh Readme.txt Wifi_direct_user_interface WPA_SUPPLICANT_HOSTAPD

android_ref_codes_kk_4.4 driver Mp_tools releasenotes.pdf wireless_tools

[Email protected] linux]# CD wireless_tools/

[[email protected] wireless_tools]# ls

Wireless_tools.30.rtl.tar.gz

[Email protected] wireless_tools]# tar-xf wireless_tools.30.rtl.tar.gz

[Email protected] wireless_tools]# CD wireless_tools.30.rtl/

[[email protected] wireless_tools.30.rtl]# make && make install

Note the following red font

... ...

Install-m 644 $lang/iftab.5/usr/local/man/$lang/man5/; \

Done

Remember to return to the execution results

[[email protected] wireless_tools.30.rtl]# echo $?

The result is 0 to indicate correct

[Email protected] wireless_tools.30.rtl]# cd/usr/local/sbin/

[Email protected] sbin]# ll

Scan around WiFi signal

[Email protected] linux]# iwlist enp0s20u6 scanning

This step is just a scan, and it's not going to connect

4. Connect the scanned WiFi

[Email protected] linux]# CD wpa_supplicant_hostapd/

[[email protected] wpa_supplicant_hostapd]# ls

p2p_hostapd.conf wpa_0_8.conf wpa_supplicant_hostapd-0.8_rtw_r7475.20130812

rtl_hostapd_2g.conf wpa_supplicant_8_jb_4.2_rtw_r8680.20130821.tar.gz Wpa_supplicant_hostapd-0.8_rtw_ R7475.20130812.tar.gz

Rtl_hostapd_5g.conf wpa_supplicant_8_kk_4.4_rtw_r11967.20140818.tar.gz

[Email protected] wpa_supplicant_hostapd]# tar-xf wpa_supplicant_hostapd-0.8_rtw_r7475.20130812.tar.gz

[Email protected] wpa_supplicant]# CD wpa_supplicant_hostapd-0.8_rtw_r7475.20130812/wpa_supplicant/

[[email protected] wpa_supplicant]# make && make install

[[email protected] wpa_supplicant]# echo $?

Connect to WiFi

[Email protected] wpa_supplicant]# wpa_passphrase sspaas.com >>/etc/wpa_supplicant/wpa_supplicant.conf return and enter the password again

88888888

[Email protected] wpa_supplicant]# cat/etc/wpa_supplicant/wpa_supplicant.conf

Ctrl_interface=/var/run/wpa_supplicant

Ctrl_interface_group=wheel

# reading passphrase from stdin

network={

Ssid= "Sspaas.com"

#psk = "88888888"

psk=c88b2e4bc1a75fe6accbe5713acd3410c61d71fc02572083d7b7510d9f325772

}

Now the drive and key files are all formed, you can make WiFi connection!!!

[Email protected] wpa_supplicant]#wpa_supplicant-i enp0s20u2-c/etc/wpa_supplicant/wpa_supplicant.conf-d wext- B

Wpa_supplicant parameter meaning:

-I indicates NIC

-C indicates where the key is stored

-D indicates that the drive type is universal

-B to run in the background

Only to do this, not enough, a reboot system, you need to re-execute the above command, so as long as the above command stored in the/etc/rc.local is OK, each time you restart the system will be automatically online

A little bit of attention at the bottom:

The driver module for this NIC is in this directory

/usr/lib/modules/3.10.0-327.el7.x86_64/kernel/drivers/net/wireless/8821au.ko

View the driver modules that the system has loaded

[Email protected] wireless]# lsmod | grep 8821

8821au 1968224 0
