第一种方法:
yum源来自chinalinuxpub.com,用的是centos包,
下载地址: http://www.chinalinuxpub.com/yum.tgz
安装:
tar zxvf yum.tgz
cd yum
rpm -ivh *.rpm
rm -rf /etc/yum.repos.d/CentOS-Base.repo
vi /etc/yum.repos.d/as4-update.repo
加入:
#released updates
[update]
name=Red Hat Enterprise AS release 4 Updates
baseurl=http://ftp.chinalinuxpub.com/redhat/enterprise/updates/4AS/
gpgcheck=1
gpgkey=http://ftp.chinalinuxpub.com/redhat/enterprise/RPM-GPG-KEY-linuxpub
vi /etc/yum.repos.d/as4-base.repo
加入:
#released base
[base]
name=Red Hat Enterprise AS release 4 Updates
baseurl=http://ftp.chinalinuxpub.com/redhat/enterprise/os/i386/RedHat/ #在这个地方可以更改能连接上的网站
gpgcheck=1
gpgkey=http://ftp.chinalinuxpub.com/redhat/enterprise/RPM-GPG-KEY-linuxpub
然后就可以正常使用yum了.
使用:
yum localinstall *.rpm
安装本地的包
也可以 yum list|grep xxx.rpm xxx为想要安装的包 然后运行yum install xxx.rpm 就可以了
/var/cache/yum 是文件下载的地方 . 可以修改/etc/yum.conf 来改变文件夹的位置.
第二种方法:
利用CentOS 的yum库升级RHEL AS4
1.下载并安装yum-2.4.0-1.centos4.noarch.rpm文件,下载地址为:
ftp://ftp.pbone.net/mirror/ftp.centos.org/4.2/os/alpha/CentOS/RPMS/yum-2.4.0-1.centos4.noarch.rpm
2.修改或建立/etc/yum.repos.d/CentOS-Base.repo为如下内容:
[base]
name=CentOS-$releasever - Base
baseurl=http://ftp.riken.jp/Linux/caos/centos/4.0/os/$basearch/
gpgcheck=1
#released updates
[update]
name=CentOS-$releasever - Updates
baseurl=http://ftp.riken.jp/Linux/caos/centos/4.0/updates/$basearch/
gpgcheck=1
#packages used/produced in the build but not released
[addons]
name=CentOS-$releasever - Addons
baseurl=http://ftp.riken.jp/Linux/caos/centos/4.0/addons/$basearch/
gpgcheck=1
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
baseurl=http://ftp.riken.jp/Linux/caos/centos/4.0/extras/$basearch/
gpgcheck=1
3.修改或建立/etc/yum.repos.d/dag.repo为如下内容:
[dag]
name=Dag RPM Repository for RHEL4
baseurl=http://ftp.riken.jp/Linux/dag/redhat/el4/en/$basearch/dag/
www.ixdba.net
enabled=1
gpgcheck=1
gpgkey=http://ftp.riken.jp/Linux/dag/packages/RPM-GPG-KEY.dag.txt
4.运行update:
yum update
5.升级:
yum upgrade
6.安装其它软件,例如:
yum install mplayer
第三种方法
http://linux.duke.edu/projects/yum/download/2.0/yum-2.0.7-1.noarch.rpm 下载,并安装yum安装后要注意的是一下三个文件
/etc/cron.daily/yum.cron #每日进行yum 及 其他软件包定时升级
/etc/init.d/yum #yum服务
/etc/yum.conf #yum配置文件
接下来修改/etc/yum.conf
vi /etc/yum.conf
将
[base]
name=Red Hat Linux $releasever - $basearch - Base
baseurl=http://mirror.dulug.duke.edu/pub/yum-repository/redhat/$releasever/$basearch/
[updates]
name=Red Hat Linux $releasever - Updates
baseurl=http://mirror.dulug.duke.edu/pub/yum -repository/redhat/updates/$releasever/
改为
[base]
name=CentOS 4.4 for RHEL4 - Base #随便取名字
baseurl= http://mirror.be10.com/centos/4.4/os/i386/
[updates]
name=CentOS 4.4 for RHEL4 - Updates #随便取名字
baseurl= http://mirror.be10.com/centos/4.4/updates/i386/
输入命令
yum update
