yum使用方法

发布时间: 2017-11-25 阅读数: 14483

提要:我们用的是Redhat/Fedora通过在线安装更新软件包,除了系统自带的up2date以外,我们还有更为强大的在线升级工具 yum 和 apt-get 可用。主要资源有 freshrpms.net和 rpm.livna.org ;

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

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。

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

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

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 |

        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

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

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

        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


软件在线升级更新yum 图形工具介绍;
作者:北南南北
来自:LinuxSir.Org
提要:yum 是Fedora/Redhat 软件包管理工具,包括文本命令行模式和图形模式;图形模式的yum也是基于文本模式的;目前yum图形前端程序主要有 yumex和kyum ;


+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
正文
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++


一、yum 在线安装、移除、更新及管理rpm软件包工具;

我们除了系统提供的软件包管理工具 system-config-packages ,但这个软件包管理工具,只能用于系统安装盘提供的软件的管理;

Fedora也提供了 up2date升级工具,但这个工具明显无任何优势;升级速度慢,效率低下,大多人是忍受不了 up2date折磨的;

yum 工具是Fedora 推荐使用的在线升级更新软件包的工具,在安装系统时,一般都是默认安装;yum 是一个命令行式的工具,如果您不习惯命令行式的yum,您可以用yumex和kyum;


yumex和kyum并不是独立于yum的,而是yum的图形前端,也就是说,我们在安装和使用yumex和kyum同时,都是以yum的安装和配置为基础;您在用yumex或kyum 时,必须先安装配置yum ;


做为初学者,如何使用yum及yum的资源,拜请您读以下几篇文档;

1、《Fedora/Redhat 在线安装更新软件包,yum 篇》
2、《Fedora Extras(Fedora 计划的扩充资源) rpm.livna.org软件仓库的介绍和应用》
3、《Freshrpms.net 资源介绍,及apt 和yum 的应用》

二、安装yumex;

注:您在用yumex或kyum 时,必须先安装配置yum ;请看前面提到的文章;

如果您用 kde桌面,您可以用kyum,yunex和kyum二者任选其一,找一个自己习惯的就行;

1、yumex 的安装和使用;

首先确认系统是不是有yumex


[root@localhost beinan]# rpm -q yumex
yumex-0.42-3.0.fc4

如果没有类似的输出,请用下面的命令安装,前提是您已经完成了前面说的yum的配置;


[root@localhost beinan]# yum install yumex

2、yumex的调用:


[beinan@localhost ~]# yumex

3、yumex的操作;会点鼠标就会用 yumex

   


三、安装kyum ;


注:yumex 和kyum您只需选择一个适合您的就行,没有必要两个都安装,不过尝试一下再做选择也好;

1、安装kyum ;


[root@localhost beinan]# yum install kyum

2、调用kyum ;


[root@localhost beinan]# kyum

3、用法图示;




四、关于yum补充:

如果您想要深入了解yum ,您必须到查看yum主页上的文档;

yum主页地址:

http://www.linux.duke.edu/projects/yum

后记:至此yum基础文档就差不多完成了,我写了一系列的教程;软件包管理基础的东西差不多就这些;如果您在教程发现您所要的东西没有,就看man;

附录一:

安装软件时,最好用各自发行版所提供的系统软件包管理工具,对于Fedora/Redhat 您可以参考如下文章;

0)RPM 基础 《RPM 的介绍和应用》

1)Fedora 系统管理软件包工具 system-config-packages,方便的添加和移除系统安装盘提供的软件包,详情请看 《Fedora 软件包管理器system-config-packages》

2)Redhat 系统管理软件包工具,新一点的系统应该是 redhat-config-packages ,用法和 《Fedora 软件包管理器system-config-packages》 一样;

3)apt + synaptic 软件包在线安装、移除、升级工具; 用法:《用apt+synaptic 在线安装或升级Fedora core 4.0 软件包》
4)yum 软件包在线安装、升级、移除工具;用法:《Fedora/Redhat 在线安装更新软件包,yum 篇》

5)所有的yum和apt 教程 《apt and yum》

6)《file.src.rpm 使用方法的简介》

7)《如何编译安装源码包软件》

提示:目前 apt和yum 已经极为成熟了,建议我们安装软件时采用 apt或者yum ;如果安装系统盘提供的软件包,可以用 system-config-packages 或redhat-config-packages ;
