yum | Ivan Pesin

Just when you think you’ve sorted things out it appears the whole world gone mad :-) Ukraine has got its next Maindan (that’s how we call a nation-wide protest here) and the time is even more scarce than it was. Here are few links to sum up and give you the taste:

Система: Red Hat Enterprise Linux 5

Решение:

Убедитесь, что пакет yum-downloadonly установлен в системе. Если нет, то этот пакет доступен в Red Hat Network (RHN). Чтобы установить пакет yum-downloadonly в системе, зарегистрированной в Red Hat Network, выполните команду:

#yum install yum-downloadonly

1

#yum install yum-downloadonly

yum-downloadonly — это плагин, который может быть использован для загрузки пакетов из RHN или репозиториев yum, без установки их в системе. Проверьте содержимое файла /etc/yum/pluginconf.d/downloadonly.conf и убедитесь, что плагин разрешён:

[main] enabled=1

1
2

[main]
enabled=1

Теперь, для примера, выполните следующую команду, которая загружает последнюю версию vsftpd, если она доступна, без установки в системе:

# yum install --downloadonly vsftpd Loading "downloadonly" plugin Loading "rhnplugin" plugin rhel-i386-server-5        100% |=========================| 1.4 kB    00:00 Setting up Install Process Parsing package install arguments Package vsftpd - 2.0.5-10.el5.i386 is already installed.

По-умолчанию, пакет сохраняется в каталог /var/cache/yum/<repo>/packages/. В нашем случае <repo> это rhel-i386-server-5. Чтобы сохранить пакет в другом каталоге, укажите параметр --downloaddir вместе с --downloadonly. Например:

#yum install --downloadonly --downloaddir=/tmp vsftpd

1

#yum install --downloadonly --downloaddir=/tmp vsftpd

В результате последняя доступная версия пакета vsftpd, если он не установлен в системе, будет загружена и сохранена в каталоге /tmp.

Чтобы скачать пакет установленный в системе, используйте команду yumdownloader. Например, в системе установлен пакет httpd-2.2.3-22.el5:

# rpm -q httpd httpd-2.2.3-22.el5

1
2

# rpm -q httpd
httpd-2.2.3-22.el5

Чтобы скачать его, воспользуйтесь командой yumdownloader:

# yumdownloader httpd-2.2.3-22.el5 Loaded plugins: fastestmirror, kmod, protectbase, rhnplugin, versionlock Loading mirror speeds from cached hostfile Reading version lock configuration 0 packages excluded due to repository protections httpd-2.2.3-22.el5.i386.rpm

# yumdownloader httpd-2.2.3-22.el5
Loaded plugins: fastestmirror, kmod, protectbase, rhnplugin, versionlock
Loading mirror speeds from cached hostfile
Reading version lock configuration
0 packages excluded due to repository protections
httpd-2.2.3-22.el5.i386.rpm

Пакет сохраняется в текущем каталоге. Чтобы указать другое место, добавьте ключ --destdir с указанием нужного каталога. За подробной информацией о возможностях и параметрах команды обращайтесь к странице руководства, доступной по команде man yumdownloader.

Прим.пер.: утилита yumdownloader входит в пакет yum-utils.
