32、程序包管理之三-yum

2021年09月17日

32.1 yum简介

CentOS:yum,dnf

URL:yum仓库路径

YUM：yellow dog，Yellowdog Update Modifier

32.2 repository

1、yum repository: yum repo

存储了众多的yum包，以及包的相关的元数据文件（放置于特定目录下：repodata）;

2、文件服务器

ftp://

http://

nfs://

file://

3、yum 客户端：

配置文件：

/etc/yum.conf：为所有仓库提供公共配置

/etc/yum.repos.d/*.repo:为仓库的指向提供配置

[root@localhost cd-rom]# rpm -qc yum

/etc/logrotate.d/yum

/etc/yum.conf

/etc/yum/version-groups.conf

仓库指向的定义：

[repositoryID]

name=Some name for this respository

baseurl=url://path/to/respository/

enabled={1|0}

gpgcheck={1|0}

gpgkey=URL

enablegroups={1|0}

failovermethod={roundrobin|priority}

默认为roundrobin，意为随机挑选；

cost=

默认为1000

4、yum命令的用法

yum [options] [command] package

显示仓库列表

yum repolist [all|enabled|disabled]:显示仓库列表

[root@localhost cd-rom]# yum repolist all

Loaded plugins: fastestmirror, langpacks

Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast

32.3 本地yum仓库配置

1、如何使用光盘当作本地yum仓库：

（1）挂载光盘至某目录，例如/media/cdrom

[root@localhost /]# mkdir /media/cdrom

[root@localhost /]# mount -r -t iso9660 /dev/cdrom /media/cdrom

（2）创建配置文件

[base]

name=CentOSlocal

#mirrorlist=file:///opt/yum.repo/

baseurl=file:///media/cdrom

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

2、yum的命令行选项

–nogpgcheck：禁止进行gpg check

–y：自动回复yes

–q：静默模式

–disablerepo=repoidglob:临时禁用此处指定的repo；

–enablerepo=repoidglob:临时禁用此处指定的repo；

–noplugins:禁用所有插件

3、yum的repo配置文件中可用的变量

$releasesever：当前OS的发行版的主版本号

$arch：平台

$basearch:基础平台

$YUM0-$YUM9

4、创建yum仓库

createrepo [options] <directory>

repo格式

[base]

name=CentOS-$releasever – test

#mirrorlist=file:///opt/yum.repo

baseurl=file:///opt/yum.repo

gpgcheck=1
