How To Download A RPM Package With All Dependencies In CentOS

download a RPM package with all dependencies
The other day I was trying to create a local repository with packages only we use often in CentOS 7. Of course we can download any package using curl or wget commands. These commands however won’t download the required dependencies. You have to spend some time and manually search and download the dependencies required by the package to install. Well, not anymore. In this brief tutorial, I will walk you through how to download a RPM package with all dependencies in two methods. I tested this guide on CentOS 7, although the same steps may work on other RPM based systems such as RHEL, Fedora and Scientific Linux.

Method 1 – Download A RPM Package With All Dependencies Using “Downloadonly” plugin

We can easily download any RPM package with all dependencies using “Downloadonly” plugin for yum command.
To install Downloadonly plugin, run the following command as root user.
yum install yum-plugin-downloadonly
Now, run the following command to download a RPM package.
yum install --downloadonly 
By default, this command will download and save the packages in /var/cache/yum/ in rhel-{arch}-channel/packages location. However, you can download and save the packages in any location of your choice using “–downloaddir” option.
yum install --downloadonly --downloaddir= 
Example:
yum install --downloadonly --downloaddir=/root/mypackages/ httpd
Sample output:
Loaded plugins: fastestmirror

 * epel: epel.mirror.angkasa.id
 * extras: centos.excellmedia.net
 * updates: centos.excellmedia.net

exiting because "Download Only" specified

Now go the location that you specified in the above command. You will see there the downloaded package with all dependencies. In my case, I have downloaded the packages in /root/mypackages/ directory.
Let us verify the contents.
ls /root/mypackages/
Sample output:
apr-1.4.8-3.el7.x86_64.rpm
apr-util-1.5.2-6.el7.x86_64.rpm
httpd-2.4.6-40.el7.centos.4.x86_64.rpm
httpd-tools-2.4.6-40.el7.centos.4.x86_64.rpm
mailcap-2.1.41-2.el7.noarch.rpm
rootserver1_003
As you see in the above output, the package httpd has been downloaded with all dependencies.
Please note that this plugin is applicable for “yum install/yum update” and not for “yum groupinstall”. By default this plugin will download the latest available packages in the repository. You can however download a particular version by specifying the version.
Example:
yum install --downloadonly --downloaddir=/root/mypackages/ httpd-2.2.6-40.el7
Also, you can download multiple packages at once as shown below.
yum install --downloadonly --downloaddir=/root/mypackages/ httpd vsftpd

Method 2 – Download A RPM Package With All Dependencies Using “Yumdownloader” utility

Yumdownloader is a simple, yet useful command-line utility that downloads any RPM package along with all required dependencies in one go.
Install Yumdownloader using the following command as root user.
yum install yum-utils
Once installed, run the following command to download a package, for example httpd.
yumdownloader httpd
To download packages with all dependencies, use –resolve option:
yumdownloader --resolve httpd
By default, Yumdownloader will download the packages in the current working directory.
To download packages along with all dependencies to a specific location, use –destdir option:
yumdownloader --resolve --destdir=/root/mypackages/ httpd
Or
yumdownloader --resolve --destdir /root/mypackages/ httpd
Sample output:
Loaded plugins: fastestmirror

Let us verify whether packages have been downloaded in the specified location.
ls /root/mypackages/
Sample output:
apr-1.4.8-3.el7.x86_64.rpm
apr-util-1.5.2-6.el7.x86_64.rpm
httpd-2.4.6-40.el7.centos.4.x86_64.rpm
httpd-tools-2.4.6-40.el7.centos.4.x86_64.rpm
mailcap-2.1.41-2.el7.noarch.rpm
rootserver1_005
Unlike “Downloadonly” plugin, Yumdownload can download the packages related to a particular group.
yumdownloader "@Development Tools" --resolve --destdir /root/mypackages/
Personally, I prefer Yumdownloader over “Downloadonly” plugin for yum. But, both are extremely easy and handy and does the same job.
That’s all for today. If you find this guide helpful, please share it on your social networks and let others to benefit.
Cheers!
