服务器评测
当你的Linux系统能连接上网络时我想你那时就不用本地源和rpm安装软件了，网络源是通过网络上的资源进行安装自己想要的软件，这样安装可以及时更新和维护系统。
1.确保自己的服务器能连接上互联网
[root@CentOS ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 08:00:27:56:AA:AA
inet addr:2.2.2.145 Bcast:2.255.255.255 Mask:255.0.0.0
inet6 addr: fe80::a00:27ff:fe56:aaaa/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:424 errors:0 dropped:0 overruns:0 frame:0
TX packets:95 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:36395 (35.5 KiB) TX bytes:12020 (11.7 KiB)
[root@centos ~]# ping www.baidu.com
PING www.a.shifen.com (115.239.210.27) 56(84) bytes of data.
64 bytes from 115.239.210.27: icmp_seq=1 ttl=54 time=18.1 ms
64 bytes from 115.239.210.27: icmp_seq=1 ttl=54 time=17.9 ms
2.编辑yum的库文件(用官方的源)
[root@RedHat1 ~]# cd /etc/yum.repos.d/
[root@redhat1 ~]# vim CentOS-Base.repo –用官方的源(去掉所有baseurl前面的#号)
[base]
name=CentOS-$releasever – Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
#released updates
[updates]
name=CentOS-$releasever – Updates
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
baseurl=http://mirror.centos.org/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=$basearch&repo=extras
baseurl=http://mirror.centos.org/centos/$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://mirror.centos.org/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=1 –启用仓库
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=$basearch&repo=contrib
baseurl=http://mirror.centos.org/centos/$releasever/contrib/$basearch/
gpgcheck=1
enabled=1 –启用仓库
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
3.用网易的网络源(其它开源镜像站点也是一样的)
[root@centos1 ~]# cd /etc/yum.repos.d/ –进入仓库根目录
[root@centos1 yum.repos.d]# ll
total 16
-rw-r–r–. 1 root root 1926 Feb 25 2013 CentOS-Base.repo1
-rw-r–r–. 1 root root 638 Feb 25 2013 CentOS-Debuginfo.repo1

-rw-r–r–. 1 root root 3664 Feb 25 2013 CentOS-Vault.repo
[root@centos1 yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo –下载163的源镜像
