On centos (7.6), I've a script to deploy a set of php dependencies with yum tools and remi-repo. I need to migrate this installation set on a redhat (7.9). On this distribution, I've this issue during installation of php-mbdstring module.
The lib libonig.so.105()(64bit) is missing. I don't found anything to fix this dependencies clearly. I've tried to install the oniguruma( and -devel) but the lib (/usr/lib64/libonig.so.5) version doesn't match with the dependency requirement. Here the output of the yum install command.

Error: Package: php-mbstring-7.2.34-1.el7.remi.x86_64 (remi-repo)
Requires: libonig.so.105()(64bit)
The libonig.so.105()(64bit) is provided by package oniguruma5php in either remi or remi-safe repositories.
Apparently, you don't have either enabled. For your use case, I would suggest enabling remi-safe (it is enabled by default, you might have disabled it by mistake):
yum install yum-utils
yum-config-manager --enable remi-safe
# dependency should be pulled in without problem:
yum install php-mbstring
