踩

centos 8188gu

引言：

最近对于嵌入式系统比较感兴趣，因此，计划先使用VMware workstation虚拟机试一试Linux系统下的网卡驱动安装

这不试不知道，一试吓一跳，发现Linux下的驱动安装还是比较麻烦的，下面将就本次的Linux系统下安装水星免驱USB网卡在Linux下的安装做一个尽量详细的记录。

一，

Linux下驱动安装的必要性

首先，Linux的稳定性是毋庸置疑的，因此，在很多情况下，Linux是首选的，但，Linux的操作系统版本是非常多的，而目前服务器方面基本是centos7或者Ubuntu

其次，openwrt这样的软路由操作系统也是需要安装网卡的，虽然我们可以直接插一个网线，使用板载网卡，但，无疑使用USB类型的网卡更方便使用嘛

最后呢，就是Linux下网卡如果安装成功后，可以做WiFi网络嗅探，WiFi热点破解这些工作了，虽然Windows下有很多WiFi破解工具，但，我想Linux下的破解工作可能会更方便，也是对自己的周边的无线网络的一个安全认识吧。

二，

环境简介

本次实践使用的是VMware workstation 虚拟机，操作系统的版本是centos7，最小化安装，网卡见下图：

插入机箱后，虚拟机选择连接该网卡：

在Linux下查看网卡，因为该网卡是USB类型的，因此，Linux下应该是可以看到一个USB类型的光驱（sr1就是这个网卡了）：


[root@centos10 ~]# lsblk

[root@centos10 ~]# blkid

/dev/mapper/centos-root: UUID="81ad8aed-bf72-4bd9-b9f4-8743e1dc074d" TYPE="xfs"

挂载此光驱到media目录下，可以看到Windows的驱动安装包，很显然，前面我们说的免驱是指的Windows下的免驱而不是Linux，Linux下还是需要安装驱动的：


[root@centos10 ~]# mount /dev/sr1 /media/
mount: /dev/sr1 is write-protected, mounting read-only
[root@centos10 ~]# cd /media/
[root@centos10 media]# ls
AutoRun.inf  SetupInstall.exe
[root@centos10 media]# ls -alh

-r-xr-xr-x   1 root root 1.9M Jun 11  2018 SetupInstall.exe

看看Linux的版本信息：


[root@centos10 media]# uname -a
Linux centos10 3.10.0-1062.el7.x86_64 #1 SMP Wed Aug 7 18:08:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
 
[root@centos10 ~]# cat /etc/redhat-release 
CentOS Linux release 7.7.1908 (Core)

进一步看看USB的信息（lsusb命令如果没有，需要安装，安装命令为 yun install usbutils -y）：


[root@centos10 ~]# lsusb

[root@centos10 ~]# lsusb -tv

    |__ Port 2: Dev 3, If 0, Class=Hub, Driver=hub/7p, 12M
        |__ Port 1: Dev 4, If 0, Class=Wireless, Driver=btusb, 12M
        |__ Port 1: Dev 4, If 1, Class=Wireless, Driver=btusb, 12M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/6p, 480M
    |__ Port 1: Dev 2, If 0, Class=Mass Storage, Driver=usb-storage, 480M

第一个命令lsusb输出的第一个就是网卡了，第二个命令lsusb -tv可以印证，因为是usb-storage嘛，480M表示是usb3.0协议，读写速度，这些不需要过多关心

主要需要关注的是ID 0bda:1a2b，利用此ID ，进一步识别网卡信息（注意，usb_modeswitch命令最小化安装没有，需要安装，yum install usb_modeswitch -y）：


[root@centos10 ~]# usb_modeswitch -KW -v 0bda -p 1a2b

[root@centos10 ~]# lsusb

再次查看USB信息，可以看到ID改变了，变为0bda:b711 ，说明Linux正确识别到了，但是，此时还没有驱动来驱动该硬件

在Linux下查询网卡芯片信息比较困难，其实比较简单的办法是在Windows下查看，见下图：

补充：

如何确定网卡的芯片型号是重中之重，关系到后面的网卡是否能正确识别使用，因此，我补充一下，如何查询网卡芯片型号的问题

芯片对应列表在这个网站http://www.linux-usb.org/usb.ids，可以查询到两个b711，第二个说的是在切换后，因此确定是8188gu了

b711  EW-7722UAC 802.11a/b/g/n/ac (2x2) Wireless Adapter [MediaTek MT7612U]

b711  RTL8188GU 802.11n WLAN Adapter (After Modeswitch)

我们可以确定该网卡的芯片是8188gu的，在网上寻找此芯片的Linux版本驱动就可以了，本次实验使用的是版本是下面的链接（第一个没有dkms.conf 第二个有dkms.conf ，第二个更加好用一些，如果会dkms的话）：

https://github.com/McMCCRU/rtl8188gu

我想这个应该也是可以的：

GitHub - wandercn/RTL8188GU: Realtek RTL8188GU Driver for TP-link TL-WN725N USB wifi

三，

相关资料介绍和驱动安装

驱动和操作系统的内核是密切相关的，因此，本例中，需要升级内核，据测试，3.10版本的内核不会成功，本例中使用的内核版本是5版本

其次，是我们下载的驱动都是c语言的，因此，gcc的版本也需要比较高，默认的gcc4.8版本经测试也是失败的，本例中使用的gcc是9版本

本例涉及使用的安装包在下面的链接：

升级内核

进入目录


[root@centos10 kernel-lt-5.4.266]# pwd

-rw-r--r-- 1 root root   603824 Jan 15 06:21 python-perf-5.4.266-1.el7.elrepo.x86_64.rpm

可以强制安装，这个没有什么影响：


[root@centos10 kernel-lt-5.4.266]# rpm -ivh ./* --force --nodeps
warning: ./kernel-lt-5.4.266-1.el7.elrepo.x86_64.rpm: Header V4 DSA/SHA256 Signature, key ID baadae52: NOKEY

安装完毕后，重启虚拟机，选择新内核，进入系统，再次激活USB：


[root@centos10 ~]# usb_modeswitch -KW -v 0bda -p 1a2b

2，

安装gcc9：

[root@centos10 11]# tar xvf gcc-9.tar


[root@centos10 11]# mkdir /opt/rh
[root@centos10 11]# mv devtoolset-9/ /opt/rh/
[root@centos10 11]# source /opt/rh/devtoolset-9/enable
[root@centos10 11]# echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile
[root@centos10 11]# source /etc/profile

验证gcc是否安装成功：


[root@centos10 11]# gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/lto-wrapper

3，

编译的环境依赖安装：

因为我前面编译过，因此，清除了上次的编译，主要是安装bc 和gcc-c++


[root@centos10 rtl8188gu-master]# yum install unzip gcc-c++ bc -y
 
 
 
[root@centos10 rtl8188gu-master]# make clean
#make -C /lib/modules/5.4.266-1.el7.elrepo.x86_64/build M=/root/11/rtl8188gu-master clean

4，

开始编译：

预编译，完成后 echo $? 看看是不是正常完成：

开始驱动安装：


[root@centos10 rtl8188gu-master]# make install
install -p -m 644 8188gu.ko  /lib/modules/5.4.266-1.el7.elrepo.x86_64/kernel/drivers/net/wireless/
/sbin/depmod -a 5.4.266-1.el7.elrepo.x86_64

可以看到，驱动是安装到了/lib/modules/5.4.266-1.el7.elrepo.x86_64/kernel/drivers/net/wireless/这个目录下，并且最后depmod 了一下

三，

检查驱动安装和使用驱动

网卡驱动安装基本上算是完成了，现在需要彻底激活此网卡

查看网卡的驱动模块是否正确加载：

没有任何输出，如果正确加载会有输出的哦

[root@centos10 rtl8188gu-master]# lsmod |grep 8188

这个时候不要慌，看看该网卡驱动的详细信息：

可以看到该网卡驱动依赖的是另一个模块cfg80211，lsmod命令没有看到cfg80211，modinfo看不到该模块的信息（备注：该模块是kernel的验证签名模块）

查看系统日志，可以看到网卡的USB无法使用：

使用modprobe命令重新激活这两个模块（没有输出表示正确哦），并查看模块是否正确加载：


[root@centos10 rtl8188gu-master]# modprobe cfg80211
[root@centos10 rtl8188gu-master]# modprobe 8188gu
[root@centos10 rtl8188gu-master]# lsmod  |grep 8188 ||grep cfg80211

cfg80211              704512  1 8188gu

这个时候，可以看到cfg80211的模块信息了（上面的说看不到信息的话，我收回！！！！！，这里表明此模块是无线连接的支持模块，收回此模块是签名验证的说法！！！！！）：

可以看到，ens33这个网卡有异常，好像多了ipv6的信息，应该是一个ipv6的，查看系统日志，看到如下报错：

<info> [1705156203.3089] device (ens33): ipv6: duplicate address check faile

因此，决定关闭ipv6，关闭步骤如下：

1，

删除ens33网卡内的所有关于ipv6的信息，最终该网卡的配置文件如下：


[root@centos10 rtl8188gu-master]# cat /etc/sysconfig/network-scripts/ifcfg-ens33 
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
NAME=ens33
UUID=abed039b-c453-47ee-acd4-301974b75aab
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.123.20
GATEWAY=192.168.123.2
NETMASK=255.255.225.0
DNS1=223.5.5.5
DNS1=223.6.6.6

2，

内核屏蔽ipv6：


[root@centos10 rtl8188gu-master]# cat /etc/sysctl.conf 
# sysctl settings are defined through files in
# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.
#
# Vendors settings live in /usr/lib/sysctl.d/.
# To override a whole file, create a new file with the same in
# /etc/sysctl.d/ and put new settings there. To override
# only specific settings, add a file with a lexically later
# name in /etc/sysctl.d/ and put new settings there.
#
# For more information, see sysctl.conf(5) and sysctl.d(5).
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

最后两行屏蔽ipv6的，然后sysctl -p 激活此设置

3，

network这个文件末尾添加no


[root@centos10 rtl8188gu-master]# cat /etc/sysconfig/network
# Created by anaconda
NETWORKING_IPV6=no

4，

重启网络


[root@centos10 rtl8188gu-master]# systemctl restart NetworkManager
[root@centos10 rtl8188gu-master]# systemctl restart network

5，

重新插拔网卡，再次查看网卡信息，新网卡出来了：


[root@centos10 rtl8188gu-master]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

    link/ether 00:5c:c2:ce:dc:24 brd ff:ff:ff:ff:ff:ff

现在需要连接WiFi了，有很多方法，比如上面资料里提到的wpa_suppliant_withoutopenssl-master，或者直接在桌面图形化方式连接

本次采用桌面方式，因此，先安装一个桌面：

yum group install "GNOME Desktop"

安装完毕后，startx命令进入桌面：

此时的网卡还没有激活，因此，激活先，看到网卡里有一个up就可以啦：


[root@centos10 rtl8188gu-master]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    link/ether 00:5c:c2:ce:dc:24 brd ff:ff:ff:ff:ff:ff

扫描WiFi热点：

或者使用iwlist命令（这个命令以后再说，现在只是演示一下）：

OK，扫描热点完毕后，就可以在桌面看到所有WiFi了，然后点击自己的WiFi，输入密码连接就可以了，我的WiFi名称是 mywif：

密码输入后，就可以看到网卡的ip了：

也有网卡配置文件了，这个文件自动生成的：


[root@centos10 wireless_tools]# cat /etc/sysconfig/network-scripts/ifcfg-mywifi 
ESSID=mywifi
MODE=Managed
KEY_MGMT=WPA-PSK
SECURITYMODE=open
MAC_ADDRESS_RANDOMIZATION=default
TYPE=Wireless
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=mywifi
UUID=7a115cd8-212d-4c6c-af4d-0edf72fab737
ONBOOT=yes

在查看系统日志，可以发现有一个报错，但该报错不影响网卡的使用，insmod出现loading out-of-tree module taints kernel，该报错主要是安全警示

以后在讲这些报错的处理以及内核和模块的管理工作

本例以完美实现，但奇怪的是ipv6为什么影响新网卡的模块加载，这个确实是有点让人疑惑的，有高手知道的话，可以告诉下我原因，不胜感激！！！！
