I was running mysql (server) version 5.0.45-7.el5.
means that this is "one" of the redhat 5 ( RHEL 5.0,5.1,5.2,5.3,5.4,5.5,5.6,5.7,5.8 )
CentOS 5.8 or Scientificlinux 5.8 ( both cent and sl ONLY support the current version in the major version)
so WHAT operating system are you using ?
RHEL is NOT free and you MUST have the REQUIRED support contract to install software
one of the FREE rebuilds ????
cent or SL
that error is from trying to install an incompatible rpm BYPASSING the distros repo
the "glibc23" on the end of that "Random" rpm file
means you MUST have a operating system BUILT with glibc 2.3
the rpm MUST MATCH your system
there is nothing i can offer untill you inform us as to what you are using
other than USE your operating system's update and base repo
yum update mysql
build and install from source the database and ALL of it's prerequisites
and for a mismatching libc
that is 80% of the operating system
exactly what operating system is it ?
2) and what version is it ?
blindly trying to bypass the safeguards in "yum" and installing an incompatible rpm from some " random place on the web"
is NEVER a good idea
