1、配置yum源
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum makecache
2、预安装各种库
sudo yum install gcc cmake bzip2-devel curl-devel db4-devel libjpeg-devel libpng-devel freetype-devel libXpm-devel gmp-devel libc-client-devel openldap-devel unixODBC-devel postgresql-devel sqlite-devel aspell-devel net-snmp-devel libxslt-devel libxml2-devel pcre-devel mysql-devel pspell-devel
3、配置输入法
sudo yum install ibus ibus-table-wubi*
打开管理面版，找到区域及语言选项，添加五笔输入法即可。
4、配置ntfs文件系统识别
官网下载ntfs-3g软件包：http://www.tuxera.com/community/open-source-ntfs-3g/
解压缩后安装：
./configure
make
make install
fdisk -l
ntfs-3g /dev/sdb2 /home/usb -o locale=ar_SA.UTF-8
5、日常办公使用centos会有很多不方便的地方，因此最好装上虚拟机 virtualbox
sudo yum install kernel-devel-$(uname -r)
sudo yum install virtualbox
virtualbox
