centos7下升级GLIBC2.31

先决条件：
升级gcc9.3.0
升级make4.3

查看当前系统版本即GLIBC信息
$ cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)

$strings /lib64/libc.so.6 | grep GLIBC

1,编译升级gcc
$ wget https://mirrors.aliyun.com/gnu/gcc/gcc-9.3.0/gcc-9.3.0.tar.gz
$ tar -zxvf gcc-9.3.0.tar.gz
$ cd gcc-9.3.0/
$ ./contrib/download_prerequisites
$ cat /proc/cpuinfo| grep “processor”| wc -l
$ mkdir build
$ cd build
$ …/configure --enable-checking=release --enable-language=c,c++ --disable-multilib --prefix=/usr
$ make -j6
$ make install
升级后gcc版本检查
$ gcc --version
gcc (GCC) 9.3.0

2,编译升级make
$ wget https://mirrors.aliyun.com/gnu/make/make-4.3.tar.gz
$ tar -zxf make-4.3.tar.gz
$ mkdir build
$ cd build
$ …/configure --prefix=/usr && make && make install
检查升级后make版本信息
$ make -v
GNU Make 4.3

3,升级glibc-2.3.1
$ wget https://mirrors.aliyun.com/gnu/glibc/glibc-2.31.tar.gz
$ tar -zxf glibc-2.31.tar.gz
$ cd glibc-2.31/
$ cat INSTALL | grep -E “newer|later”
$ mkdir build
$ cd build
$ …/configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin --disable-sanity-checks --disable-werror

yum install python3 //如果编译时出现报错可能时python版本过低，升级一下重新编译即可

$ make -j6
$ make install
$ make localedata/install-locales

最后验证升级后的glibc版本
