Linux 7.2 Recovery after mis-deletion of glibc

Today to install Oracle on a test server, with Yum installation dependent package always prompt glibc version conflict, originally installed version is relatively high, so hand owed directly rpm-e glibc and Glibc-common to delete, and then operations to find I said server login not up , and my side has been the error:

-bash:/usr/bin/ls:/lib64/ld-linux-x86-64.so.2:bad ELF interpreter:no such file or directory

No matter what the operation is to report the above error, thought this is finished, is not necessary to re-install the server AH. Consulted with SA, said it is possible to use the CD-ROM boot into recovery mode to repair.

The idea is to copy the missing files back.

Enter Repair mode

Missing after the discovery or the file, and then after a reboot, the system still cannot boot.

Later thought that the lost files should not only be reported out of those, there are many do not know the package has also been lost.

On the Internet to find an introduction to the recovery method of the blog, the first is that I used this method, he said that is not recoverable, and then the second method is to reinstall the GLIBC software package, and then began a second attempt:

The blog also has a third method of recovery, where there is no attempt, interested students can try.
