While working on RHEL and CentOS Servers there are some scenarios where we want to download the particular or set of RPM packages from the command the line without installing it. Though we can use wget command to download packages but wget will not download package dependencies.
Using ‘yumdownloader‘ command we can easily download rpm package along with its dependencies, as its name suggest it will not install the package but only downloads. In other words we can say yumdownloader is a utility for downloading RPMs from yum repositories.I have tested the yumdownloader command on CentOS 7.x / RHEL 7.x
Let’s first install yumdownloader utility using below command.
Open the terminal and execute the beneath yum command
[[email protected] ~]# yum install yum-utils
Example:1 Download a particular package
# yumdownloader <package_name>
[[email protected] ~]# yumdownloader bind-utils
Above command will download the package in the current working directory and it will not download package dependencies.
Example:2 Download rpms and its dependencies in particular folder.
–destdir option in yumdownloader command is used to specify the path of directory where we want to save the downloaded rpms.
–resolve option in yumdownloader will resolve the dependency and will download the required packages.
Let’s assume we want to download Samba and Web (httpd) Server rpm packages along with its dependencies under the folder ‘/opt/downloaded_rpms‘
[[email protected] ~]# mkdir /opt/downloaded_rpms [[email protected] ~]# yumdownloader samba httpd --destdir /opt/downloaded_rpms --resolve
Now Verify the whether the packages are downloaded under the specified directory or not.
Example:3 Download the packages related to a particular group
Let’s assume that we want to download all the packages which comes under the group “Development Tools”
[[email protected] ~]# yumdownloader "@Development Tools" --destdir /opt/downloaded_rpms --resolve
