yum簡介

yum = Yellow dog Updater, Modified

主要功能是更方便的新增/刪除/更新RPM包.

它能自動解決包的倚賴性問題.

它能便於管理大量系統的更新問題

當前linux版本 rhel7.0

前提

mount DVD光碟到/mnt 因為配置時候路徑名裡面不能有空格,否則不能識別

[root@LiuZhen mnt]# mount /dev/sr0 /mnt

在目錄/etc/yum.repos.d/建立檔案檔名.repo

也可以VI直接編輯

[root@LiuZhen mnt]# cat> /etc/yum.repos.d/dvd.repo<< EOF

> [testyum]

> name=dvd

> baseurl=

> enable=1

> EOF

編輯完成，檢視一下

[root@LiuZhen mnt]# cat /etc/yum.repos.d/dvd.repo

[testyum]

name=dvd

baseurl=

enable=1

匯入release相關檔案

[root@LiuZhen mnt]# rpm --import RPM-GPG-KEY-redhat-release

以上已經配置完成，安裝dovecot進行測試

安裝dovecot包檔案

[root@LiuZhen mnt]# yum -y install dovecot
