GLIBC_2.14’ not found.” on CentOS 6.x.

mkdir ~/glibc214
cd ~/glibc214
wget http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz
tar zxvf glibc-2.14.tar.gz
cd glibc-2.14
mkdir build
cd build
../configure — prefix=/opt/glibc-2.14
make -j4
sudo make install
export LD_LIBRARY_PATH=/opt/glibc-2.14/lib (for current login session)
OR add LD_LIBRARY_PATH=/opt/glibc-2.14/lib in the /etc/environment and perform source /etc/environment(to add env variable permanently)
或者 ln -s /opt/glibc-2.14/lib/libc-2.14.so /usr/lib64/libc.so.6

安装中遇到的问题在执行make install中遇到：ld.so.conf: No such file or directory

mkdir -p /opt/glibc-2.14/etc
touch /opt/glibc-2.14/etc/ld.so.conf

然后重新执行make install
