YUM是在基于RPM的系统上使用的命令行软件包管理实用程序。

YUM-安装包管理器

YUM(最初称为Yellowdog Updater Modified)是一个命令行软件包管理器,用于基于rpm的Linux发行版。Yum最初是为了管理Red Hat Enterprise Linux系统而创建的,但是现在许多其他流行的发行版都使用此工具作为首选的命令行软件包管理器。诸如CentOS和Fedora之类的发行版都使用Yum。Yum提供了一个易于使用的界面来更新和删除软件包。百胜还处理所有依赖项和先决条件。

yum命令示例

Yum中最常用的功能是 "install", "erase", "update", "list" 和 "search"。但是,yum具有更多可以执行的功能。以下是yum的一些常见用法:

显示YUM版本

基本语法:yum --version

[root@centos01a ~]# yum --version

更新特定软件包

基本语法:yum update package name

yum update命令用于更新特定的软件包。在使用更新选项之前,检查软件包的当前版本并检查是否有较新的版本很有用。为此,我们可以使用yum list命令显示当前安装的版本以及任何可用的版本。

[root@centos02a ~]# yum list openssl

openssl.x86_64    1.0.1e-42.el6_7.2     updates 

从上面的输出中,我们可以看到软件包openssl.x86_64的版本为1.0.1e-42.el6,并且有更新的版本1.0.1e-42.el6_7.2。要更新此软件包,我们使用yum update命令:

许多软件包被分组为方便的组。这使系统管理员可以使用一个命令安装一组软件包。命令yum grouplist可用于显示系统上的可用组。(下面是grouplist命令的摘录)。

安装一组软件包-yum groupinstall groupname

在下面的示例中,我们将安装X Window System。要安装X Window System软件包组,我们执行命令yum groupinstall'X Window System'。(请注意,如果组包的名称中包含空格,则必须在组名周围加上单引号。)
我们可以看到有233个软件包组成了X Window System组。

[root@centos01a ~]# yum groupinstall 'X Window System'
