Each stream consists of a series of module versions (such as httpd:2.4:8040020210127115317 and httpd:2.4:8050020210517115912) and each module version lists RPM packages belonging to it (see the Artifacts section in the output from yum module info httpd:2.4).Ī module stream is active if the developer enables it explicitly, or if it is the default and has not been explicitly disabled. Modules are organized into streams (examples include httpd:2.4, perl:5.24, and perl:5.30 also see the yum module list command output). To resolve the invisible package problem, you need to understand how modules work. This issue is sometimes known as the invisible package problem. The new package isn't there, but why? Because packages belonging to an active module stream take precedence over other packages of the same name. Last metadata expiration check: 0:06:19 ago on Fri 01:31:22 PM CEST. Check which packages YUM sees: $ repoquery httpd It doesn't work! YUM cannot see your new httpd-2.4.86_64 package.

Next, let's try to update the system to install the patched package: # yum upgrade Register the repository to YUM under the name myhttpd by creating the /etc//devel.repo file with the following content: Let's say that the repository is located in the working directory /root/repos/myhttpd, so all write operations there must be performed by a superuser: # createrepo_c. Next, turn the directory into a YUM repository. This results in the following binary packages: $ ls Now, build the modified package with a rpmbuild tool.

Unpack it and apply the following patch to a specification file, as explained in the Red Hat documentation: - a/httpd.spec Step 1: Build a new packageįirst, obtain the source RPM package, httpd-2.4.37-40.module+el8.5.0+11022+, which corresponds to our example. Our quest is to patch the module to report My Linux instead. The output shows that the httpd-2.4.37-40.module+el8.5.0+11022+1c90597b RPM package was installed from the httpd:2.4 module stream and that the server reports Apache/2.4.37 (Red Hat Enterprise Linux). Server: Apache/2.4.37 (Red Hat Enterprise Linux) $ wget -no-proxy -S -O /dev/null - 12:58:54- Resolving localhost (localhost). Last metadata expiration check: 0:03:40 ago on Fri 12:51:49 PM CEST. I have highlighted the relevant lines from the output in bold: # yum install httpd To get started, install an httpd RPM package, start the HTTPD server, and check the server name.
As an example, we can change the HTTPD web server to report a different server name in the HTTP response headers.

That means you can take the code sources, change them, recompile them, and use or redistribute the modified software.
#Redhat enterprise linux versions how to#
This article shows you how to patch a module stream while avoiding the invisible package problem. Is it more difficult than patching non-modular software? Slightly. That's great, but what if you want to patch a stream? Is it possible? It is. Modules enable new features such as adding alternative versions of stacks, called streams.
#Redhat enterprise linux versions software#
Red Hat Enterprise Linux (RHEL), in version 8, introduced modules as a higher-level concept for packaging software stacks.
