To install package in RHEL6.x /CentOS 6.x,use below given command
yum install yum-plugin-downloadonly
To install package in RHEL5.x /CentOS 5.x,use below given command
yum install yum-downloadonly
After installation get completed,you can find two new options in yum command
Run the command yum --help
for more information.
Downloadonly Plugin Options:
(1) --downloadonly
: don’t update, just download
(2) --downloaddir=/path/to/directory
: specifies an alternate directory to store packages
Notes:
(1) The downloadonly plugin can be enable/disable from /etc/yum/pluginconf.d/downloadonly.conf file. To enable the downloadonly, in downloadonly.conf file confirm “enabled=1″ (to disable “enabled=0″)
(2) Without using –downloaddir option,files are saved in by-default path /var/cache/yum/. Further from this path,you have to change directory into OS-architecture/channel/package-directory
Example. In this eg. path is /var/cache/yum/x86_64/6/base/packages/ (Reference from CentOS 6.5,arch:x86_64)
[root@localhost ~]# ls -l /var/cache/yum/x86_64/6/base/packages/
total 152
-rw-r--r--. 1 root root 154576 Mar 1 2013 vsftpd-2.2.2-11.el6_4.1.x86_64.rpm
[root@localhost ~]#
(3) This is not applicable to “yum groupinstall”.It is applicable to “yum install” and “yum update”.Whereas, you can use “yum groupinfo” to check the packges in a specific group
(4) By-default it downloads latest available package from yum repository.To download particular package,use the full package name.(example- vsftpd-2.2.2-11.el6)
How to download rpm file by using downloadonly plugin
After installing downloadonly plugin,we are ready to download rpm package.
Example: In this we are downloading vsftpd.By-default it will download to /var/cache/yum directory
yum install --downloadonly vsftpd
Check the path in dir /var/cache/yum . (After this directory path,the location of downloaded package may be differ as per Operating System Version and architecture)
Example:
[root@localhost ~]# ls -l /var/cache/yum/x86_64/6/base/packages/
total 152
-rw-r--r--. 1 root root 154576 Mar 1 2013 vsftpd-2.2.2-11.el6_4.1.x86_64.rpm
[root@localhost ~]#
How to download rpm file in specific directory by using downloadonly plugin
To download rpm file in specific directory, we will use option –downloaddir along with –downloadonly
Example: In this eg. we are creating new directory called packages, for downloading rpm into it.You can specify to any other accessible pre exist directory(like /opt , /tmp , user’s home directory) . Specify the path of destination directory in –downloaddir option
mkdir -p ~/packages
yum install --downloadonly --downloaddir=~/packages wget
Check the file,in specified directory
[root@localhost ~]# ls -l ~/packages/
total 636
-rw-r--r--. 1 root root 494344 Feb 11 16:24 wget-1.12-1.11.el6_5.x86_64.rpm
[root@localhost ~]#
Method 2: Using yumdownloader for downloading rpm files without installing it in linux system

command has lots of option.We will specify only few ,which are frequently we use.

command,the package will be downloaded into the current path of user. (See given below examples)
Install yum-utils package.After installation ,we can use the yumdownloader
command
