How to Make Rpm Auto Install Dependencies

How to make rpm auto install dependencies

Create a (local) repository and use yum to have it resolve the dependencies for you.

The CentOS wiki has a nice page providing a how-to on this. CentOS wiki HowTos/CreateLocalRepos.

Summarized and further minimized (not ideal, but quickest):

1. Create a directory for you local repository, e.g. /home/user/repo.
2. Move the RPMs into that directory.

3. Fix some ownership and filesystem permissions:

   # chown -R root.root /home/user/repo
   

4. Install the createrepo package if not installed yet, and run

   # createrepo /home/user/repo
   # chmod -R o-w+r /home/user/repo
   

5. Create a repository configuration file, e.g. /etc/yum.repos.d/myrepo.repo containing

   [local]
   name=My Awesome Repo
   baseurl=file:///home/user/repo
   enabled=1
   gpgcheck=0
   

6. Install your package using

   # yum install packagename
   

when creating RPM package, how to auto install dependencies

You can't do it directly, you cannot install another RPM from within your RPM spec file.

The normal way, which you should follow, is to make your RPM depends on the other RPMs it needs, e.g. by adding this to your .spec file:

 Requires:  gcc, mysql-server, mysql-devel

When you then try to install your rpm with the rpm command:

rpm -ivh yourrpm-1.0.0.rpm

it will fail and tell you which packages to install, and you have to install those packages manually first.

Or you can use yum to install your rpm file:

 yum install ./yourrpm.1.0.0.rpm

and yum will download and install the required dependencies before it installs your RPM package.

Automatically install build dependencies prior to building an RPM package

You can use the yum-builddep command from the yum-utils package to install all the build dependencies for a package.

The arguments can either be paths to spec files, paths to source RPMs or the names of packages which exist as source RPMs in a configured repository, for example:

yum-builddep my-package.spec

or

yum-builddep my-package.src.rpm

The same thing can be achieved on newer versions of Fedora that use dnf as their package manager by making sure that dnf-plugins-core is installed and then doing:

dnf builddep my-package.spec

or

dnf builddep my-package.src.rpm

How to install a rpm package and its dependencies offline

In CentOS/RedHat you can use yumdownloader for specific packages, this downloads all RPMs required, then, compress the directory, upload it to the server without Internet access and install RPMs.

Here you can find and example, installing Kubernetes without Internet access.

yumdownloader --assumeyes --destdir=/var/rpm_dir/docker-ce --resolve docker-ce
tar -czvf d4r-k8s.tar.gz /var/rpm_dir
# Upload files
scp d4r-k8s.tar.gz root@YOUR-IP:/root
# Connect to your server
ssh root@YOUR-IP
tar -xzvf /root/d4r-k8s.tar.gz -C /
# install Docker:
yum install -y --cacheonly --disablerepo=* /var/rpm_dir/docker-ce/*.rpm

Make rpm package without any dependencies. However when the rpm package is installed in the environment, there is a problem of missing dependencies

What you're looking for is to disable the internal dependency generator:

%global _use_internal_dependency_generator 0

That said, your binary will not work unless you make sure those libraries are somehow accessible to it.

If you want it to have no dependency and not ship the libraries inside the package, you need to build it statically. E.g. -static option for gcc.

Provide dependencies of RPM for offline install

You can't do what you're asking in %pre and %post, because (a) those are executed at install time which is well after dependency resolution and (b) you wouldn't be able to call rpm to install things from your %pre because the database is locked for the transaction you are part of.

When I've done something like this in the past, I have found the easiest thing to do is to put all the RPMs in a single directory on the media and instruct the deployment team to yum localinstall *rpm from that directory. If some of the third-party RPMs are older than what is installed, it will just skip over them.

Install other dependency rpm during the rpm installation

You cannot manipulate the RPM database in scriptlets. You need to put Requires: java-11-openjdk and then provide the RPM in the same manner as your own software, e.g. yum/dnf repository, burned to a CD, etc.
