一、啟用sudo
1、查看sudo是否安裝
rpm -qa|grep sudo
2、修改sudoers文件
在root ALL=(ALL) ALL 之后增加
zhunian ALL=(ALL) ALL
zhunian為需要啟用sudo的用戶名
二、配置本地光盤源
由於安裝好系統，無線網卡不能驅動起來，只好先配置光盤源，安裝一些依賴包，為下面編譯安裝無線網卡驅動做准備。
1、備份文件CentOS-Media.repo
sudo cp /etc/yum.repos.d/CentOS-Media.repo /etc/yum.repos.d/CentOS-Media.repo.bak
2、按以下內容修改文件CentOS-Media.repo
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///media/CentOS_6.2_Final/ #按本機光盤掛載的實際路徑修改
# file:///media/cdrom/
# file:///media/cdrecorder/
gpgcheck=1
enabled=1 #值修改為1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
3、安裝編譯網卡所需的依賴包
sudo yum --disablerepo=\* --enablerepo=c6-media install make
sudo yum --disablerepo=\* --enablerepo=c6-media install kernel-headers
sudo yum --disablerepo=\* --enablerepo=c6-media install kernel-devel
注意：如果還缺少其它依賴包，請按提示安裝。
4、下載RTL8188CE無線網卡驅動
下載地址
注意：下載Linux driver for kernel 2.6.23 (and earlier)這個驅動，另外一個驅動編譯提示缺少變量。
5、解壓下載的驅動，進入解壓后的文件夾，編譯安裝驅動，然后重啟
sudo make
sudo make install
sudo reboot
6、重啟后進入系統就可以發現無線網卡已經驅動起來了。
三、配置yum更新源
1、備份文件CentOS-Base.repo
sudo mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
2、配置CentOS-Base.repo文件，內容如下
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#
[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
#released updates
[updates]
name=CentOS-$releasever - Updates
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
baseurl=http://mirrors.163.com/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
baseurl=http://mirrors.163.com/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus
baseurl=http://mirrors.163.com/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
#contrib - packages by Centos Users
[contrib]
name=CentOS-$releasever - Contrib
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib
baseurl=http://mirrors.163.com/centos/$releasever/contrib/$basearch/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
3、清理、生成本地緩存
sudo yum clean all
sudo yum makecache #將服務器上的軟件包信息緩存到本地,以提高搜索安裝軟件的速度
sudo yum install vim* #測試域名是否可用
4、開始更新系統
sudo yum update
更新系統后重啟，如果內核更新了，無線網卡驅動可能用不了，按第一步重新來一便就行來。
四、安裝顯卡驅動
1、下載ATI 6630官方比源驅動
wget http://www2.ati.com/drivers/linux/amd-driver-installer-12-3-x86.x86_64.run
2、從run文件提取deb安裝包
sudo ./amd-driver-installer-12-1-x86.x86_64.run --buildpkg RedHat/RHEL6
注意：可以用以下命令查看驅動支持的系統
sudo ./amd-driver-installer-12-1-x86.x86_64.run --listpkg
3、安裝驅動
sudo rpm -ivh fglrx_p_i_c-8.93-1.i386.rpm
4、生成配置文件，重啟
sudo aticonfig --initial -f
sudo reboot
五、清理升級后的舊內核
1、列出系統中正在使用的內核
uname -a
2、查詢系統中的全部內核
rpm -qa | grep kernel
3、刪除舊內核
sudo yum remove kernel-2.6.32-220.el6.i686
sudo yum remove kernel-devel-2.6.32-220.el6.i686
4、重啟
六、自動登錄
主要是修改 /etc/gdm/custom.conf ，添加AutomaticLogin和TimedLogin 重啟即可
# GDM configuration storage
[daemon]
AutomaticLoginEnable=true
AutomaticLogin=zhunian
TimedLoginEnable=true
TimedLogin=zhunian
TimedLoginDelay=7
[security]
AllowRoot=false
[xdmcp]
[greeter]
DefaultWelcome=false
Welcome=Wait seconds...
Logo=/usr/share/pixmaps/faces/penguin.jpg
[chooser]
[debug]
[server-Chooser]
name=Chooser server
command=/usr/bin/Xorg -audit 0
chooser=false
handled=true
flexible=false
priority=0
七、安裝Flash插件
1、下載flashplayer11_rc1_install_lin_64_090611.tar.gz解壓
下載地址：http://labs.adobe.com/downloads/flashplayer10_square.html
解壓出來得到一個名叫：libflashplayer.so的文件，還有一個user的文件夾。
2、解壓出來的libflashplayer.so文件拷貝到/usr/lib/firefox-3.6
3、然后執行下列命令，重啟瀏覽器
ln/usr/lib/firefox-3.6/libflashplayer.so/usr/lib/mozilla/plugins/libflashplayer.so
注：可以直接下載安裝文件“http://get.adobe.com/flashplayer/”
八、掛載NTFS
1、下載rpmforge的rpm文件包
sudo wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-1.el6.rf.i686.rpm
2、安裝rpmforge的rpm文件包
sudo rpm -ivh rpmforge-release-0.5.2-1.el6.rf.i686.rpm
3、裝ntfs-3g
sudo yum install fuse-ntfs-3g
成功后你會發現已經可以掛載NTFS了
