用yum源來在線安裝軟件，yum源在線軟件

1、刪除redhat原有的yum源

# rpm -aq | grep yum|xargs rpm -e --nodeps

2、下載新的yum安裝包

　　這裡我們使用CentOS的yum源

# wget http://mirror.centos.org/centos/6.3/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
# wget http://mirror.centos.org/centos/6.3/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm
# wget http://mirror.centos.org/centos/6.3/os/i386/Packages/yum-3.2.29-30.el6.centos.noarch.rpm # wget http://mirror.centos.org/centos/6.3/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

3、安裝yum軟件包

# rpm -ivh  python-iniparse-0.3.1-2.1.el6.noarch.rpm
# rpm -ivh  yum-metadata-parser-1.1.2-16.el6.i686.rpm
# rpm -ivh  yum-3.2.29-30.el6.centos.noarch.rpm  yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

注意：最後兩個安裝包要放在一起同時安裝，否則會提示相互依賴，安裝失敗。

4、更改yum源 #我們使用網易的CentOS鏡像源

# cd /etc/yum.repos.d/
# wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo
# vi CentOS6-Base-163.repo

　　編輯文件，把文件裡面的$releasever全部替換為版本號，即6 最後保存！或者直接把下面的內存拷貝到CentOS6-Base-163.repo文件中即可（已經修改好）

# 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.

5、清理yum緩存

# yum clean all
# 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
# yum install vim*    #測試域名是否可用

至此，Redhat6可以使用CentOS的yum源在線安裝軟件了！

6.使用 # yum update

或 # yum upgrade 升級系統

注：兩個命令區別：

# yum update

升級所有包，改變軟件設置和系統設置,系統版本內核都升級
# yum -y upgrade
升級所有包，不改變軟件設置和系統設置，系統版本升級，內核不改變

注：Redhat6.2默認源指定使用CentOS6-Base-163.repo，將上述內容進行替換。
