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:

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
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 Loading mirror speeds from cached hostfile * base: centos.excellmedia.net * epel: epel.mirror.angkasa.id * extras: centos.excellmedia.net * updates: centos.excellmedia.net --> Running transaction check ---> Package httpd.x86_64 0:2.4.6-40.el7.centos.4 will be installed --> Processing Dependency: httpd-tools = 2.4.6-40.el7.centos.4 for package: httpd-2.4.6-40.el7.centos.4.x86_64 --> Processing Dependency: /etc/mime.types for package: httpd-2.4.6-40.el7.centos.4.x86_64 --> Processing Dependency: libaprutil-1.so.0()(64bit) for package: httpd-2.4.6-40.el7.centos.4.x86_64 --> Processing Dependency: libapr-1.so.0()(64bit) for package: httpd-2.4.6-40.el7.centos.4.x86_64 --> Running transaction check ---> Package apr.x86_64 0:1.4.8-3.el7 will be installed ---> Package apr-util.x86_64 0:1.5.2-6.el7 will be installed ---> Package httpd-tools.x86_64 0:2.4.6-40.el7.centos.4 will be installed ---> Package mailcap.noarch 0:2.1.41-2.el7 will be installed --> Finished Dependency Resolution (1/5): apr-util-1.5.2-6.el7.x86_64.rpm | 92 kB 00:00:01 (2/5): mailcap-2.1.41-2.el7.noarch.rpm | 31 kB 00:00:02 (3/5): apr-1.4.8-3.el7.x86_64.rpm | 103 kB 00:00:02 (4/5): httpd-tools-2.4.6-40.el7.centos.4.x86_64.rpm | 83 kB 00:00:03 (5/5): httpd-2.4.6-40.el7.centos.4.x86_64.rpm | 2.7 MB 00:00:19
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
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!
