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 -r 3.10.0-957.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.gz cp gcc-9.3.0.tar.gz /opt cd /opt tar -zxf gcc-9.3.0.tar.gz cd 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 -l mkdir build cd build ../configure --enable-checking=release --enable-language=c,c++ --disable-multilib --prefix=/usr make -j6 make install
2)升级成功后gcc版本检查
cd /usr/lib64 ll libstdc++* gcc -v gcc --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.gz cp make-4.3.tar.gz /opt cd /opt/ tar -zxf make-4.3.tar.gz cd make-4.3/ mkdir build cd 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 /opt 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 make -j6 make install make 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 GLIBC ll /lib64/libc.so*
