yum的配置和使用

因为练习要用redhat，而redhat因为没有注册所以没有yum，没有yum的redhat就是鸡肋。为了解决这个问题，可以用以下方法。

一、卸载redhat yum

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

二、安装centos yum
给网易做广告了……

# cd /tmp/
# wget http://mirrors.163.com/centos/5/os/i386/CentOS/yum-3.2.22-37.el5.centos.noarch.rpm
# wget http://mirrors.163.com/centos/5/os/i386/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm
# wget http://mirrors.163.com/centos/5/os/i386/CentOS/yum-fastestmirror-1.1.16-16.el5.centos.noarch.rpm
# rpm -ivh yum-*

三、配置.repo

# vim /etc/yum.repos.d/CentOS5-Base-163.repo

引用

# 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.
#

五、使用

# yum makecache

六、可能出现的问题
yum makecache出错，这可能是因为$releasever的值=5os
在vim中用命令

:%s/$releasever/5/g

修改repo

七、使用光盘

# mount /dev/dvd /media
# vim Local.repo

引用

[Local]
name=Local
baseurl=file:///media/Server
enabled=1
gpgcheck=0

测试

# yum search samba --disablerepo=\* --enablerepo=Local
