【原创】Linux基础之redhat6升级glibc-2.12到2.14

redhat6自带glibc-2.12，升级到glibc-2.14过程

# wget http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz
# tar xvf glibc-2.14.tar.gz
# cd glibc-2.14
# mkdir build
# cd build
# /path/to/glibc-2.14/configure --prefix=/opt/glibc-2.14
# make
# make install

# export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

# cp /opt/glibc-2.14/libc-2.14.so /lib64/
# cd /lib64
# ln -snf libc-2.14.so libc.so.6

# strings /lib64/libc.so.6 |grep GLIBC_

configure时必定不要用

# /path/to/glibc-2.14/configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin

不然一旦make install报错，后果可能很严重，详见：http://www.javashuo.com/article/p-schhzsbz-dx.html
