centos安装vim失败解决方法：（推荐：vim教程）
在线安装vim: yum install vim
今天我在用CentOS 5.5的yum命令安装的时候出现如下错误：
[root@malu2 ~]# yum install vim Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirror.hosting90.cz * extras: mirror.hosting90.cz * updates: mirror.hosting90.cz Setting up Install Process No package vim available. Nothing to do
解决办法：
更新一下yum仓库：
#yum -y update
再次运行安装，发现错误依旧，看来这种猜包名的方法不适用；所以接下来可以通过yum的查找参数来列出vim相关的包名:
[root@malu2 yum.repos.d]# yum search vim Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirror.hosting90.cz * extras: mirror.hosting90.cz * updates: mirror.hosting90.cz ===================== Matched: vim =================== vim-X11.x86_64 : The VIM version of the vi editor for the X Window System. vim-common.x86_64 : The common files needed by any version of the VIM editor. vim-enhanced.x86_64 : A version of the VIM editor which includes recent : enhancements. vim-minimal.x86_64 : A minimal version of the VIM editor.
通过查看，我们可以看到，yum列出了详细的vim相关的包名，这样就可以顺利的安装vim了：
#yum -y install vim-enhanced.x86_64
