yum (Yellowdog Updater Modified)是一个集与查找,安装,更新和删除程序的Linux软件。它运行在RPM包兼容的Linux发行版本上,如:RedHat, Fedora, SUSE, CentOS, Mandriva。

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

对于此错误,我一般习惯性先去更新一下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

以上命令就能执行成功了。当然不仅仅vim安装,其他程序比如mysql我们也同样只要先进行yum查找,再通过匹配详细包名来进行安装,就不会出现上述错误了。
