CentOS7下升级GLIBC2.31

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*
