1．網絡配置
（1）命令配置
# ifconfig eth0 192.168.0.2 netmask 255.255.255.0 //ip地址、子網掩碼
# route add default gw 192.168.0.1 dev eth0 //網關
# hostname centos //計算機名
（2）文件配置
<1>修改IP地址
修改對應網卡的IP地址的配置文件
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0 (描述網卡對應的設備別名，例如ifcfg-eth0的文件中它為eth0)
BOOTPROTO=static (設置網卡獲得ip地址的方式，可能的選項為static，dhcp或bootp，分別對應靜態指定的ip地址，通過dhcp協議獲得的ip地址，通過bootp協議獲得的ip地址)
BROADCAST=192.168.0.255 (對應的子網廣播地址)
HWADDR=00:07:E9:05:E8:B4 (對應的網卡物理地址)
IPADDR=12.168.1.2 (如果設置網卡獲得ip地址的方式為靜態指定，此字段就指定了網卡對應的ip地址)
IPV6INIT=no (開啟或關閉IPv6；關閉no，開啟yes)
IPV6_AUTOCONF=no (開啟或關閉IPv6自動配置；關閉no，開啟yes)
NETMASK=255.255.255.0 (網卡對應的網絡掩碼)
NETWORK=192.168.1.0 (網卡對應的網絡地址)
ONBOOT=yes (系統啟動時是否設置此網絡接口，設置為yes時，系統啟動時激活此設備)
<2>修改網關
修改對應網卡的網關的配置文件
# vi /etc/sysconfig/network
NETWORKING=yes (表示系統是否使用網絡，一般設置為yes。如果設為no，則不能使用網絡，而且很多系統服務程序將無法啟動)
HOSTNAME=centos (設置本機的主機名，這里設置的主機名要和/etc/hosts中設置的主機名對應)
GATEWAY=192.168.1.1 (設置本機連接的網關的IP地址。例如，網關為10.0.0.2)
<3>修改DNS
修改對應網卡的DNS的配置文件
# vi /etc/resolv.conf
nameserver 202.101.224.68 (域名服務器)
nameserver 202.101.224.69 (域名服務器)
<4>重新啟動網絡配置
# service network restart
或
# /etc/init.d/network restart
2．軟件源配置
國內速度較快的常用更新源如下：
http://mirrors.163.com/centos/ 163-網易
http://mirrors.ta139.com/centos/ 中國移動通信（山東移動）
http://centos.ustc.edu.cn/centos/ 中國科學技術大學
http://mirror.neu.edu.cn/centos/ 東北大學
編輯yum配置文件：
#vi /etc/yum.repos.d/CentOS-Base.repo
[base]
name=CentOS-$releasever - Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/
http://mirrors.ta139.com/centos/$releasever/os/$basearch/
http://centos.ustc.edu.cn/centos/$releasever/os/$basearch/
http://mirror.neu.edu.cn/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
#released updates

gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
#baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/

gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
#additional packages that extend functionality of existing packages

然后使用如下命令更新到最新系統：
#rpm –import /etc/pki/rpm-gpg-key*
#yum upgrade3．安裝語言包
從安裝盤進行安裝，找到對應rpm包：
fonts-chinese-3.02-9.6.el5.noarch.rpm
fonts-ISO8859-2-75dpi-1.0-17.1.noarch.rpm
可以通過yum進行安裝，安裝辦法為：
#yum groupinstall <language>-support
在 上面的命令中，<language> 是下列之一: assamese, bengali, chinese, gujarati, hindi, japanese, kannada, korean, malayalam, marathi, oriya, punjabi, sinhala, tamil, thai, 或 telegu。
4．解壓縮軟件
#yum install unrar unzip p7zip-full
