在公司接手一台服務器，准備做點想做的事，發現竟然連vim都沒有，沒事，我自己裝，悲劇的發現連Yum都沒裝…..
服務器的的環境是Red Hat Enterprise Linux AS release 4 (Nahant Update 8)，這都早八百年的老系統了，服務器的配置還行。好了，我們開始干正事，我的目標是：
- 1. 安裝Yum，配置好CentOS的源，選了網易163的源
- 2. 順便用Yum安裝一個Vim來玩
首先從這篇文章Red Hat 安裝Yum,按照下面的步驟來安裝Yum
先下載Yum的rpm包
cd /syr/local/ wget -c http://yum.baseurl.org/download/2.0/yum-2.0.8-1.src.rpm
使用rpm方式安裝
rpmbuild --rebuild yum-2.0.8-1.src.rpm cd /usr/src/redhat/RPMS/noarch/ rpm -ivh yum-2.0.8-1.noarch.rpm
運行yum會出現報錯
retrygrab() failed for: http://mirror.dulug.duke.edu/pub/yum-repository/redhat/4AS/i386/headers/header.info Executing failover method failover: out of servers to try Error getting file http://mirror.dulug.duke.edu/pub/yum-repository/redhat/4AS/i386/headers/header.info [Errno 4] IOError:
Red Hat默認的源太老了，都沒辦法更新了,得更換為163的源.
修改yum.conf配置文件
vi /etc/yum.conf
詳細配置如下:
[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
根據163的說明，配置好/etc/yum.repos.d/CentOS-Base.repo文件，就可以開始安裝Vim了。
先找到Vim的安裝包
yum list | grep vim
會列出與vim相關的包
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
安裝vim-enhanced.i386這個包就可以了
yum install vim-enhanced.i386
會提示你是否導入GPG key，輸入y即可:
warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 443e1821 Public key for vim-enhanced-6.3.046-2.el4.1.i386.rpm is not installed Retrieving GPG key from http://mirror.centos.org/centos/RPM-GPG-KEY-centos4 Importing GPG key 0x443E1821 "CentOS-4 key " Is this ok [y/N]: y
最后終於安裝成功了，Vim我愛死你了。

Done!
