How to download the RPM package in CentOS and all its dependencies, I believe that many inexperienced people do not know what to do, so this article summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

We can download any package using curl or wget, but these commands cannot download the required dependent package. You have to take some time and manually to find and download the packages on which the installed software depends. However, we do not have to do so. In this short tutorial, I will show you how to download the package and all its dependent packages in two ways. I've tested it under CentOS 7, but these same steps may work on other distributions based on RPM management systems, 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 download the RPM package and all its dependent packages through the "Downloadonly" plug-in of the yum command.

To install the Downloadonly plug-in, run the following command as root.

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 package to the rhel- {arch}-channel/packageslocation directory of / var/cache/yum/, but you can also download and save the package to any location, which you can specify with the-downloaddir option.

Yum install-downloadonly-downloaddir=

Example:

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

Terminal output:

Now go to the directory location you specified, and you will see that there are downloaded packages and dependent software there. In my case, I have downloaded the 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.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 [object Object]

As you can see from the output above, the httpd package has been downloaded based on all dependencies.

Note that this plug-in works for yum install/yum update, but not for yum groupinstall. By default, this plug-in will download the packages available in the repository. However, you can download a particular software version by specifying the version number.

Example:

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

In addition, you can download multiple packages at one time as follows:

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

Method 2 use the "Yumdownloader" tool to download the RPM package and all its dependent packages

"Yumdownloader" is a simple but useful command-line tool that downloads any RPM package and all its dependencies at once.

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 package, such as httpd.

Yumdownloader httpd

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

Yumdownloader-resolve httpd

By default, Yumdownloader will download the 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:

Loaded plugins: fastestmirror

Let's make sure that the package is downloaded to the directory we specified.

Ls / root/mypackages/

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

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

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