Fedora/Redhat在线安装更新软件包 yum篇

发布时间:2006-01-07 09:51:07来源:红联作者:root
在本文中,我们主要解介绍 Fedora core 4.0 通过软件包管理工具yum来在线安装更新软件;关于apt工具应用,我们会在另外一篇中介绍;

一、 yum 的使用;

有些初学Linux的弟兄可能问,为什么不用系统自带的图形化工具up2date来升级,却要用 yum呢。其实大家用一用就知道了,up2date 真是奇慢无比,而且经常失去响应;造成机器假死的情况。所以我们还是试一试yum ;另外freshrpms.net 可能比官方站更快的更新升级源,也没有理由不用 yum;

1、首先我们要到下面的地址下载与自己系统相对应的版本的 yum;

http://ayo.freshrpms.net/

比如我用的是Fedora core 4.0 就下载如下的包安装;


[root@localhost beinan]# rpm -ivh freshrpms-release-1.1-1.fc.noarch.rpm
warning: freshrpms-release-1.1-1.fc.noarch.rpm: Header V3 DSA signature: NOKEY, key ID e42d547b
Preparing... ########################################### [100%]
1:freshrpms-release ########################################### [100%]

2、安装软件举例;

比如我要安装能听mp3的 bmp-mp3,只要输入下面的命令行即可,系统就自己工作了;

[root@localhost beinan]# yum install bmp-mp3

内容全景如下:


[root@localhost beinan]# yum install bmp-mp3

Complete!

注:yum优点:软件包依赖关系自行解决,比如上面的,我们可以看到本来我们只安装的是bmp-mp3,结果yum 安装也安装了 id3lib ;bmp

二、yum的一点小用法;

1、查询软件包;

面对成千上万的软件,我们可能无从下手,有时也不知道它的文件名;这时就要用到查询;我们可以用 yum list 来列出yum升级源上的包有文件;然后我们再来查看 info
有以下几个组合可以用;比如;

[root@localhost beinan]# yum list |more

加上一个管道 |,然后 more 一下,就能把所有的包分页显示出来。然后按一下空格键就能看下一页了。在显示的软件列表中,会有软件名称、版本、是否安装等;仔细的看一下吧。熟悉了就好了。也没有什么难的。


[root@localhost beinan]# yum list |more

Installed Packages
4Suite.i386 1.0-8.b1 installed
Canna.i386 3.7p3-13 installed
Canna-devel.i386 3.7p3-13 installed

如果想知道软件的详细信息,可能得用上info参数了。比如:

用法:


[root@localhost beinan]# yum info 软件名

比如:


[root@localhost beinan]# yum info bmp-mp3

Summary: MP3 playback plugin for the Beep Media Player
Description:
This package contains an MP3 playback plugin for BMP (Beep Media Player),
a media player that uses a skinned user interface based on Winamp 2.x skins,
and is based on ("forked off") XMMS.

在上面的例子中,如果Repo : freshrpms是这样的,表示您的系统没有安装这个软件,如果显示的是:Repo : installed,表示已经安装了。

查询软件包,也可以再加参数 grep ,比如我们想查询升级源上是否有内核的新版本,则我们可以用下面的命令查询;当然您也可以用 [root@localhost beinan]# yum search kernel |more ,也就是yum --help提供的参数,也是一样的;


[root@localhost beinan]# yum list |grep kernel

我们看一下机器工作的结果,如下:


[root@localhost beinan]# yum list |grep kernel

上面的确显示出一大堆与内核有关的, installed表示我们的系统已经安装了;

咱们看前一列吧,看一下名字就能猜个差不多;比如 doc 肯定和内核文档有关了;smp是多处理器的内核;其它的我不懂了,请想知道的弟兄用 info来看吧。

比如我们用的机器是单处理器的X86机,想看一下是否有新内核可用。所以咱们试一下下面的这个。看是否已经有了新内核可以升级的;


[root@localhost beinan]# yum info kernel.i686
[root@localhost beinan]# yum info kernel.i686

通过上面的信息,我们可以看到 2.6.11的是已经安装了,因为已经显示的是Repo : installed ,下面还有一个Version: 2.6.12 ,告诉我们是Repo : updates-released,看来这个是升级用的了。

所以是否升级就看我们的了。


[root@localhost beinan]# yum update kernel

Is this ok [y/N]:

是不是升级,只需要在 Is this ok [y/N]:行的后面输入y或者N;y是yes,就是点头同意的意思;N就是摇头No的意思。

对于软件包的查询,还有,比如:


[root@localhost beinan]# yum list available 列出所有升级源上的包;
[root@localhost beinan]# yum list updates 列出所有升级源上的可以更新包;
[root@localhost beinan]# yum list installed 列出已经安装的包;

yum 的命令支持通配符; 比如;


[root@localhost beinan]# yum list mp* |more

Reading repository metadata in from local files
Installed Packages
mpage.i386 2.5.4-5 installed

mplayer-fonts.noarch 1.1-3.fc freshrpms
mplayer-skins.noarch 1.7-1.fc freshrpms
[root@localhost beinan]#

2.安装和升级软件包;

安装和升级分别是 install 和 update 参数;比如;

[root@localhost beinan]# yum update firefox

这样我们就可以升级 firefox了。


[root@localhost beinan]# yum update firefox

Is this ok [y/N]:

如果不加参数的 update 会是什么呢??


[root@localhost beinan]# yum update

试着运行一下看看?会好长时间,对系统进行全面更新,我们要进行y和N了。

3.移除软件包要用到remove参数;比如;


[root@localhost beinan]# yum remove bmp-mp3

内容全景如下:


[root@localhost beinan]# yum remove bmp-mp3

三、yum的图形工具;

请参见:《软件在线升级更新yum 图形工具介绍》

四、yum的帮助;

在论坛中有好多,有兴趣的弟兄自己找找看吧;但也不要忘记了自救;呵。。。。


[root@localhost beinan]# yum --help
Usage: yum [options] < update | install | info | remove | list |
clean | provides | search | check-update | groupinstall |
groupupdate | grouplist | groupinfo | groupremove |
makecache | localinstall | shell >
Options:
-c [config file] - specify the config file to use
-e [error level] - set the error logging level
-d [debug level] - set the debugging level
-y - answer yes to all questions
-R [time in minutes] - set the max amount of time to randomly run in
-C run from cache only - do not update the cache
--installroot=[path] - set the install root (default '/')
--version - output the version of yum
--exclude=package to exclude
--disablerepo=repository id to disable (overrides config file)
--enablerepo=repository id to enable (overrides config file)
-h, --help - this screen

还有更厉害的帮助;


[root@localhost beinan]#man yum
