Centos:/lib/libc. so.6: version glibc_2.7 not found

When running a program on the centos server, the error/usr/local/bin/unrar:/lib64/libc. so.6: version 'glibc _ 100' not found is returned.
First, update glibc.

Yum update glibc

The result still does not work.

So I checked the glibc version.

Rpm-qi glibc

Display that the glibc Library version of the system is 2.5
Finally, we had to manually download The glibc 2.7 source code package to compile and install the update.

Wget http://ftp.gnu.org/pub/gnu/glibc/glibc-2.7.tar.gz
 
Tar zxvf glibc-2.7.tar.gz
 
./Glibc-2.7/configure # you cannot enter the glibc-2.7 folder when you execute the configure command; otherwise, you cannot execute
 
Cd glibc-2.7
 
Make install

After installation, you will find that the problem about centos:/lib/libc. so.6: version glibc_2.7 not found has to be solved.
