Downloadonly plugin for yum

There are two ways to download a package without installing it.

One is using the “downloadonly” plugin for yum, the other is using “yumdownloader” utility.

Downloadonly plugin for yum

  1. Install the package including “downloadonly” plugin:
    (RHEL5)
    # yum install yum-downloadonly

    (RHEL6)
    # yum install yum-plugin-downloadonly
  1. Run yum command with “—downloadonly” option as follows:
    # yum install --downloadonly --downloaddir=<directory> <package>
  1. Confirm the RPM files are available in the specified download directory.

Note:

* Before using the plugin, check /etc/yum/pluginconf.d/downloadonly.conf to confirm that this plugin is "enabled=1"
* This is applicable for "yum install/yum update" and not for "yum groupinstall". Use "yum groupinfo" to identify packages within a specific group.
* If only the package name is specified, the latest available package is downloaded (such as sshd). Otherwise, you can specify the full package name and version (such as httpd-2.2.3-22.el5).
* If you do not use the --downloaddir option, files are saved by default in /var/cache/yum/ in rhel-{arch}-channel/packages
* If desired, you can download multiple packages on the same command.
* You still need to re-download the repodata if the repodata expires before you re-use the cache. By default it takes two hours to expire.

Yumdownloader

If downloading a installed package, “yumdownloader” is useful.

  1. Install the yum-utils package:

    # yum install yum-utils
    
  2. Run the command followed by the desired package:

    # yumdownloader <package>
    

Note:

* The package is saved in the current working directly by default; use the --destdir option to specify an alternate location.
* Be sure to add --resolve if you need to download dependencies.

Example by Centos 6.8

# cat /etc/redhat-release 
CentOS release 6.8 (Final)

yumdownloader --resolve --destdir=/root/mysql-server mysql-server

yumdownloader --resolve --destdir=/root/owncloud owncloud

/etc/init.d/iptables stop
chkconfig iptables off

rpm -ivh *.rpm   

/etc/init.d/httpd start

netstat -lntop |grep 80

chkconfig httpd on
chkconfig mysqld on
