CentOS 6 - Update GLIBC (libc.so.6)

I'm trying to update glibc from 2.12 to 2.14.

I've tried this:
yum install ftp://rpmfind.net/linux/fedora/linux/updates/15/x86_64/glibc-2.14.1-6.i686.rpm
yum update ftp://rpmfind.net/linux/fedora/linux/updates/15/x86_64/glibc-2.14.1-6.i686.rpm

But either way it says:
Examining /var/tmp/yum-root-wKTjts/glibc-2.14.1-6.i686.rpm: glibc-2.14.1-6.i686
Marking /var/tmp/yum-root-wKTjts/glibc-2.14.1-6.i686.rpm as an update to glibc-2.12-1.47.el6_2.9.x86_64
No Packages marked for Update

And then the version is still 2.12.

Any ideas!?

Using the versions for fedora 15 from rpmfind instead of from the CentOS 6 repos is probably going to break your server in short order.

The CentOS 6.x kernels are from between fedora 12 and 14 timeline... that's why it still uses GNOME 2.

yum -Uvh --nosignature ftp://rpmfind.net/linux/fedora/linux/updates/15/x86_64/glibc-2.14.1-6.i686.rpm..

Once you run this if there is any error, please copy paste the error completely

I get this yum error:

oops sorry typo

rpm -Uvh --nosignature ftp://rpmfind.net/linux/fedora/linux/updates/15/x86_64/glibc-2.14.1-6.i686.rpm

Please copy paste the output if unsuccessful, I think there are some dependencies that needs to be addressed.

Should I not also be using x86_64, because it's a 64-bit system?
Download the required glibc-common and glibc from the site and issue the below command. It should solve your issue.

yum localinstall --disablerepo=* glibc-common-glibc-2.14.rpm glibc-2.14.rpm

Yes you need to use  x86_64 instead of i686
Download and save glibc-common-2.14.1-6.x86_64.rpm and glibc-2.14.1-6.x86_64.rpm to localdrive.

run the command

yum localinstall --disablerepo=* glibc-common-2.14.1-6.x86_64.rpm glibc-2.14.1-6.x86_64.rpm

Why do you want to update glibc on CentOS 6?

Updating glibc is generally problematic.  There are kernel and library dependencies.  It's easy to have your system become unusable.  As @Darr247 mentions, if you pick and chose RPMs from other distributions, you are likely to trash your system.

You asked for ideas:
  1)  Don't replace glibc.  If you do then
  2)  Make a full image backup of your system before trying this
  3)  Don't use yum
  4)  Install ALL related dependencies in one call to "rpm"
If you're doing this to run the latest versions of Chrome, you should use Richard Lloyd's script from

His script installs the most-recent version of glibc (that doesn't crash C6) segregated in its own folder so only Chrome uses it, which should keep your server from getting corrupted by incorrect versions of supported libraries.
This info is still relevant now and will remain relevant for the support-life of CentOS 6 (sometime in 2020).
