1、当前系统版本及GLIBC版本信息

[root@localhost ~]# cat /etc/redhat-release CentOS Linux release 7.6.1810 (Core) [root@localhost ~]# uname -r3.10.0-957.el7.x86_64[root@localhost ~]#  strings /lib64/libc.so.6 | grep GLIBC[root@localhost ~]# ll /lib64/libc.so*

2、源码编译升级gcc9.3.0

1)编译升级gcc

wget https://mirrors.aliyun.com/gnu/gcc/gcc-9.3.0/gcc-9.3.0.tar.gzcp gcc-9.3.0.tar.gz /optcd /opttar -zxf gcc-9.3.0.tar.gzcd gcc-9.3.0/ ./contrib/download_prerequisites建议先手动下载依赖的这四个包，下载地址ftp://gcc.gnu.org/pub/gcc/infrastructure/cat /proc/cpuinfo| grep "processor"| wc -lmkdir buildcd build../configure --enable-checking=release --enable-language=c,c++ --disable-multilib --prefix=/usrmake -j6make install

2)升级成功后gcc版本检查

cd /usr/lib64ll libstdc++*gcc -vgcc --version

3、源码编译升级make

1)编译升级make

wget https://mirrors.aliyun.com/gnu/make/make-4.3.tar.gzcp make-4.3.tar.gz /optcd /opt/tar -zxf make-4.3.tar.gz cd make-4.3/mkdir buildcd build../configure --prefix=/usr && make && make install

2)检查升级后的make版本信息

make -v

4、升级glibc-2.31

cd /optwget https://mirrors.aliyun.com/gnu/glibc/glibc-2.31.tar.gztar -zxf glibc-2.31.tar.gzcd glibc-2.31/cat INSTALL | grep -E "newer|later"mkdir buildcd build../configure  --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin --disable-sanity-checks --disable-werroryum install python3make -j6make installmake localedata/install-locales

报错是由于python版本较低

下面yum install python3解决后重新配置并make编译安装

../configure  --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin --disable-sanity-checks --disable-werror

make -j6

make install

最后验证升级后的glibc版本

strings /lib64/libc.so.6 | grep GLIBCll /lib64/libc.so*
