the source url is ineffective, replace it with https://ftp.gnu.org/gnu/glibc/glibc-2.18.tar.gz

Can I update it without root?

ubuntu20.4如何将glibc2.31升级到2.32?

It is more straightforward to replace centos7 (after all, centos7 is really old)

how to undo? I have now critical errors with almost every command

have you solved it? I meet the same problem. @Georodin

I solved it like this:

  1. Find what the variable has stored $LD_LIBRARY_PATH
echo $LD_LIBRARY_PATH

Example result:

/usr/local/lib:/usr/local/lib64:/opt/glibc-2.18
  1. Remove the following:
:/opt/glibc-2.18

It would look like this (for example):

/usr/local/lib:/usr/local/lib64
  1. Save it to variable $LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib64

If all commands fails after adding new glibc in LD_LIBRARY_PATH, simply try
unset $LD_LIBRARY_PATH
