Download the RPM package and all its dependent packages from CentOS

Download the RPM package and all its dependent packages from CentOS

You must spend some time and manually searching for and downloading the software packages that the installed software depends on. However, we do not have. In this short tutorial, I will show you how to download the software package and all its dependent packages in two ways. I have tested it in CentOS 7, but these same steps may also work in other release versions based on the RPM management system, such as RHEL, Fedora, and Scientific Linux.

Method 1 download the RPM package and all its dependent packages using the Downloadonly plug-in

We can use the Downloadonly plug-in of the yum command to download the RPM package and all its dependent packages.
To install the Downloadonly plug-in, run the following command as root.

yum install yum-plugin-downloadonly

Run the following command to download an RPM package.

yum install --downloadonly <package-name>

By default, this command will download and save the software package to the rhel-{arch}-channel/packageslocation directory of/var/cache/yum/. However, you can also download and save the software package to any location. You can use the-downloaddir option to specify the package.

yum install --downloadonly --downloaddir=<directory> <package-name>

Example:

yum install --downloadonly --downloaddir=/root/mypackages/ httpd

Terminal output:

Now go to the directory you specified, and you will see the downloaded software packages and dependent software. In this case, I have downloaded the software package to the/root/mypackages/directory. Let's take a look at the content:

ls /root/mypackages/

Sample output:

apr-1.4.8-3.el7.x86_64.rpmapr-util-1.5.2-6.el7.x86_64.rpmhttpd-2.4.6-40.el7.centos.4.x86_64.rpmhttpd-tools-2.4.6-40.el7.centos.4.x86_64.rpmmailcap-2.1.41-2.el7.noarch.rpm

As you can see in the above output, the httpd package has been downloaded based on all dependencies.
Note that this plug-in applies to yum install/yum update, but not to yum groupinstall. By default, this plug-in will download the latest available software packages in the repository. However, you can download a specific software version by specifying the version number.
Example:

yum install --downloadonly --downloaddir=/root/mypackages/ httpd-2.2.6-40.el7

You can also download multiple packages at a time as follows:

yum install --downloadonly --downloaddir=/root/mypackages/ httpd vsftpd

Method 2 Use Yumdownloader to download the RPM package and all its dependent packages

Yumdownloader is a simple but useful command line tool that can download any RPM software package and all its dependent packages at one time.
Run the following command as root to install the Yumdownloader tool.

yum install yum-utils

Once the installation is complete, run the following command to download a software package, such as httpd.

yumdownloader httpd

To download the software package based on all dependencies, we use the -- resolve parameter:

yumdownloader --resolve httpd

By default, Yumdownloader downloads the software package to the current working directory.
To download the software to a specific directory, we use the -- destdir parameter:

yumdownloader --resolve --destdir=/root/mypackages/ httpd

Or,

yumdownloader --resolve --destdir /root/mypackages/ httpd

Terminal output:

Let's check whether the software package is downloaded to the directory we specified.

ls /root/mypackages/

Terminal output:

apr-1.4.8-3.el7.x86_64.rpmapr-util-1.5.2-6.el7.x86_64.rpmhttpd-2.4.6-40.el7.centos.4.x86_64.rpmhttpd-tools-2.4.6-40.el7.centos.4.x86_64.rpmmailcap-2.1.41-2.el7.noarch.rpm

Unlike the Downloadonly plug-in, Yumdownload can download a set of related software packages.

yumdownloader "@Development Tools" --resolve --destdir /root/mypackages/

In my opinion, I like Yumdownloader better than Yum's Downloadonly plug-in. However, both are easy to understand and can do the same job.
