How to install glibc package version 2.28+ on RHEL 7 unofficially for testing purposes?

By Saket Jain Published June 22, 2022 Linux/Unix

In this post, we will see an interesting topic how to install glibc package version 2.28 on RHEL 7 or CentOS 7.

CentOS or RHEL does not officially support this and provides glibc version 2.17 as official version.

Since these packages affect the core OS, upgrading unofficial version makes your OS out of support.

However in some scenarios we need this version for testing.

Hence i thought to put this trick here.

1. Download glibc 2.28 packages.

[root@ngelinux001 ~]# wget http://mirror.centos.org/centos/8-stream/BaseOS/x86_64/os/Packages/glibc-devel-2.28-158.el8.x86_64.rpm

Here we need to change all the links from 2.17.so library to 2.28 libraries exists in /usr/lib64 or /lib64 directory.

We need to delete all these links and create new ones.

The correct way is to build the package using below steps, however this seems to not work on RHEL 7 or CentOS 7
