从头到尾配置yum

开发机上的yum不能用.少了这个好东西装东西不是麻烦的要死.比如为了快速调试要安装eclipse for c++

这个东西要有openjdk的支持.也就是相当于要装java虚拟机.我就弄了一下yum

首先删除yum

然后到下载相应的包

python-iniparse-0.2.3-4.el5.noarch.rpm  yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
m2crypto-0.16-8.el5.i386.rpm  yum-3.2.22-39.el5.centos.noarch.rpm     yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm

也可以这么干
解压缩后rpm -ivh *

安装相应的包

2. 导入系统自身的PGP key
rpm --import /usr/share/rhn/RPM-GPG-KEY

3.最后配置更新源

从网上的帖子来看无一例外是用wget

这样的方法来处理.可是咱的系统是红帽子的.用起来老是出问题.

后来发现问题出在

name=CentOS-$releasever - Base - 163.com
mirrorlist=
baseurl=
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

$releasever里面.因为这里的更新源是centos的.所以红帽子用起来不是那么的顺.那就把所有的$releasesever换成里面一个可以用的数字就行了.

弄完运行yum makecache

就行了.剩下的yum update yum -y upgrade

最后安装openjdk

yum install *openjdk*

 

给一个我改后的repo文件

# 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.
