centos6.6 glibc升级至2.15(附dockerfi

Dockerfile

FROM centos:6.6
RUN yum install -y wget tar gcc && yum clean all
RUN mkdir -p /opt/tmp && wget http://ftp.gnu.org/gnu/glibc/glibc-2.15.tar.gz -O /opt/tmp/glibc-2.15.tar.gz &&\
cd /opt/tmp && tar -xzvf glibc-2.15.tar.gz &&\
cd glibc-2.15 &&\
mkdir build &&\
cd build &&\
../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin &&\
make &&\
make install &&\
rm -rf /opt/tmp

glibc查看

1. strings /lib64/libc.so.6 |grep GLIBC_ 查看glibc最高支持版本
2. ll /lib64/libc**可以看到此时的libc.so.6是libc-2.12.so的别名
3. ldd --version glibc的版本

glibc2.15安装

mkdir -p /opt/tmp 
wget http://ftp.gnu.org/gnu/glibc/glibc-2.15.tar.gz -O /opt/tmp/glibc-2.15.tar.gz 
cd /opt/tmp && tar -xzvf glibc-2.15.tar.gz 
cd glibc-2.15 
mkdir build 
cd build 
../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
make && make install 
rm -rf /opt/tmp
