最详细的Linux YUM命令使用教程

 

YUM(Yellow dog Updater, Modified)为多个Linux发行版的前端软件包管理器,例如 Redhat RHEL, CentOS & Fedora.  YUM通过调用RPM的软件包信息让用户更方便地进行软件安装,升级,卸载等软件包管理操作。

这篇教程适用所有使用YUM管理软件包的Linux发行版,包括CentOS, RHEL or Fedora.

怎么使用YUM命令升级所有RPM软件包?

yum update

怎么使用YUM命令升级单个RPM软件包

yum update 软件名称

使用YUM安装RPM软件包

yum install 软件名称

使用YUM升级全部软件时怎么排除个别软件

假如你想升级所有软件包,但不想升级内核,就可以用下面的命令: yum --exclude=package kernel* update

怎么使用YUM来确定某个软件需要升级

下面的命令会检测 Fedora/CentOS/RHEL上的所有软件是否需要升级

check-update

使用YUM卸载软件

yum remove 软件名称 或者 yum erase 软件名称

使用YUM查看软件包相关信息

yum list可以让你获取软件包相关信息,后面不指定软件包名的话,它会列出所有软件包的信息。 yum list 软件名称

使用yum了解软件的主要功能

比如你想知道httpd这个软件是干吗的,可以输入下面的的命令: yum provides httpd

[root@ zhetenger ~]# yum provides nginx
Loaded plugins: priorities
nginx-.0.5-3.el6.i686 : A high performance web server and reverse proxy server
Repo        : epel

使用YUM查找软件包

如果你不知道某个软件包的全称,这个命令就非常有用了,它会根据你提供的关键词在RPM的软件包数据库里搜索相适配的软件包。比方说我想找 samba这个软件的全称,我只需要输入下面的命令即可: yum search samba

然后会显示下面的信息:

Loaded plugins: priorities

使用YUM查看软件包的基本信息

>[ root@zhetenger ~]#  yum info samba
Loaded plugins: priorities
Installed Packages

Description :
            : Samba is the suite of programs by which a lot of PC-related

            : lists of available files and printers). The Windows NT, OS/2, and
            : Linux operating systems support this natively, and add-on packages

            : Samba uses NetBIOS over TCP/IP (NetBT) protocols and does NOT
            : need the NetBEUI (Microsoft Raw NetBIOS frame) protocol.

怎么清除YUM缓存和下载包文件

每安装一个软件包,YUM都是先下载一个RPM软件包然后再安装,安装完后并不会自动删除。时间长了,这些文件占很多空间的。所以,需要定时清理: yum clean all

怎么使用YUM安装本地RPM包

如果你想要自己创建一个RPM软件包,你你可以用YUM来确定存在哪些依赖关系: yum localinstall 软件名称.rpm

使用YUM升级本地RPM软件包

如果你想升级一个本地RPM软件包,可以用下面的命令: yum localupdate update-package.rpm

确定RPM包依赖哪些组件

如果你想自己源码安装软件,了解安装的软件包依赖哪些软件非常有必要的。deplist可以让你知道软件包依赖哪些组件,这些组件的全称是什么。 yum deplist 软件名称

查看YUM的版本信息

yum -v

使用YUM安装软件包到chroot环境(chroot)

你可以使用下面的命令把软件安装到chroot: yum --installroot=/path/to/chroot/

使用YUM启用已存在的软件源

如果你安装了第三方的软件源,你需要先启用该软件源才能从其安装软件,输入下面的命令启用EPEL软件源: yum --enablerepo=epel install rsnapshot

使用YUM禁用软件源

如果你安装了第三方软件源但不想从其安装软件,可以用下面的命令禁用: yum --disablerepo=epel install 软件名称

YUM软件集合

YUM软件集合是指多个共同协作的软件统称,比如“Development Tools”(开发工具)。 下面介绍下怎么用yum groupinstall命令来查看/安装/卸载yum软件集合

安装yum软件集合

yum groupinstall 'Development Tools'

卸载yum软件集合

yum groupremove 'Development Tools'

升级yum软件集合

yum groupupdate 'Development Tools'

查看yum软件集合信息

yum groupinfo 'Development Tools'

查看有哪些软件集合

yum grouplist | more

使用YUM输出已安装软件包列表

Getting Started

  1. Download and Install Oracle Linux
  2. Download and copy the appropriate yum configuration file in place, by running the following commands as root:

    Oracle Linux 4, Update 6 or Newer

    # cd /etc/yum.repos.d # mv Oracle-Base.repo Oracle-Base.repo.disabled # wget http://public-yum.oracle.com/public-yum-el4.repo 

    Oracle Linux 5

    # cd /etc/yum.repos.d # wget http://public-yum.oracle.com/public-yum-el5.repo 

    Oracle Linux 6

    # cd /etc/yum.repos.d # wget http://public-yum.oracle.com/public-yum-ol6.repo 

    Oracle VM 2

    # cd /etc/yum.repos.d # wget http://public-yum.oracle.com/public-yum-ovm2.repo 
  3. Enable the appropriate repository by editing the yum configuration file
    • Open the yum configuration file in a text editor
    • Locate the section in the file for the repository you plan to update from, e.g. [el4_u6_base]
    • Change enabled=0 to enabled=1
  4. Begin using yum, for example:yum listyum install firefox

You may be prompted to confirm the import of the Oracle OSS Group GPG key.

Oracle Linux有两种内核:兼容Red Hat Enterprise Linux的内核(使用RHEL源代码编译)和Oracle自己的Unbreakable Enterprise内核。Oracle声明Unbreakable Enterprise内核兼容RHEL,Oracle中间件和经过RHEL认证的第三方应用程序可以不经过修改的在Unbreakable Enterprise内核上运行。
