在公司接手一台服务器，准备做点想做的事，发现竟然连vim都没有，没事，我自己装，悲剧的发现连Yum都没装…..
服务器的的环境是Red Hat Enterprise Linux AS release 4 (Nahant Update 8)，这都早八百年的老系统了，服务器的配置还行。好了，我们开始干正事，我的目标是：
- 1. 安装Yum，配置好CentOS的源，选了网易163的源
- 2. 顺便用Yum安装一个Vim来玩
首先从这篇文章Red Hat 安装Yum,按照下面的步骤来安装Yum
先下载Yum的rpm包
cd /syr/local/
wget -c http://yum.baseurl.org/download/2.0/yum-2.0.8-1.src.rpm
wget -c http://yum.baseurl.org/download/2.0/yum-2.0.8-1.src.rpm
使用rpm方式安装
rpmbuild --rebuild yum-2.0.8-1.src.rpm
cd /usr/src/redhat/RPMS/noarch/
rpm -ivh yum-2.0.8-1.noarch.rpm
cd /usr/src/redhat/RPMS/noarch/
rpm -ivh yum-2.0.8-1.noarch.rpm
运行yum会出现报错

[Errno 4] IOError:
Red Hat默认的源太老了，都没办法更新了,得更换为163的源.
修改yum.conf配置文件
vi /etc/yum.conf
详细配置如下
[main]
cachedir=/var/cache/yumdebuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
installonlypkgs=kernel kernel-smp kernel-devel kernel-smp-devel kernel-largesmp kernel-largesmp-devel kernel-hugemem kernel-hugemem-devel
distroverpkg=centos-release
tolerant=1
exactarch=1
retries=20
obsoletes=1
gpgcheck=1
plugins=1
# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

# PUT YOUR REPOS HERE OR IN separate files named file.repo

根据163的说明，配置好/etc/yum.repos.d/CentOS-Base.repo文件，就可以开始安装Vim了。
先找到Vim的安装包
yum list | grep vim
会列出与vim相关的包
vim-minimal.i386 1:6.3.046-2.el4.1 installed
vim-X11.i386 1:6.3.046-2.el4.1 base
vim-common.i386 1:6.3.046-2.el4.1 base
vim-enhanced.i386 1:6.3.046-2.el4.1 base
vim-X11.i386 1:6.3.046-2.el4.1 base
vim-common.i386 1:6.3.046-2.el4.1 base
vim-enhanced.i386 1:6.3.046-2.el4.1 base
安装vim-enhanced.i386这个包就可以了
yum install vim-enhanced.i386
会提示你是否导入GPG key，输入y即可
warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 443e1821

最后终于安装成功了，Vim我爱死你了。
