install the glibc_2.18 into the centos 7 server

we want to install the glibc_2.18 into the centos 7 server , we already have the glibc_3.XX multiple versions on the server but our application needs this dependancy . The most important thing to be noted is that the newer version 2.18 once installed then it should not take down the server and should not impact the ongoing behaviour of the other process runing on the server .The tech need to be the expertise and should be confident to get the solution worked for this .
We have already tried the below
mkdir /glibc_install; cd /glibc_install
wget http://ftp.gnu.org/gnu/glibc/glibc-2.XX.tar.gz
tar zxvf glibc-2.18.tar.gz
cd glibc-2.18
mkdir build
cd build
../configure --prefix=/usr
make -j4
make install
export LD_LIBRARY_PATH=/usr/glibc-2.XX/lib
