用yum源來線上安裝軟體，yum源線上軟體

用yum源來線上安裝軟體，yum源線上軟體
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.rpm3、安裝yum軟體包

# 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

　　編輯檔案，把檔案裡面的$releasever全部替換為版本號碼，即6 最後儲存！或者直接把下面的記憶體拷貝到CentOS6-Base-163.repo檔案中即可（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.##[base]name=CentOS-6 - Base - 163.combaseurl=http://mirrors.163.com/centos/6/os/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=osgpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#released updates[updates]name=CentOS-6 - Updates - 163.combaseurl=http://mirrors.163.com/centos/6/updates/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=updatesgpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#additional packages that may be useful[extras]name=CentOS-6 - Extras - 163.combaseurl=http://mirrors.163.com/centos/6/extras/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=extrasgpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#additional packages that extend functionality of existing packages[centosplus]name=CentOS-6 - Plus - 163.combaseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=centosplusgpgcheck=1enabled=0gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#contrib - packages by Centos Users[contrib]name=CentOS-6 - Contrib - 163.combaseurl=http://mirrors.163.com/centos/6/contrib/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=contribgpgcheck=1enabled=0gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#########################################################################

5、清理yum緩衝

# yum clean all# yum makecache     #將伺服器上的軟體包資訊緩衝到本地,以提高搜尋安裝軟體的速度# yum install vim*    #測試網域名稱是否可用

 至此，Redhat6可以使用CentOS的yum源線上安裝軟體了！

 6.使用 # yum update 

       或 # yum upgrade 升級系統

註：兩個命令區別：        

    # yum  update 

    升級所有包，改變軟體佈建和系統設定,系統版本核心都升級
    # yum -y upgrade
    升級所有包，不改變軟體佈建和系統設定，系統版本升級，核心不改變

 

註：Redhat6.2預設源指定使用CentOS6-Base-163.repo，將上述內容進行替換。
