1.修改yum源为阿里云镜像

1.1.查看现有的yum源，并备份

ll /etc/yum.repos.d/
cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
cp /etc/yum.repos.d/CentOS-SCLo-scl.repo /etc/yum.repos.d/CentOS-SCLo-scl.repo.backup
cp /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo.backup

1.2.修改yum源

2.安装依赖

2.1.安装gcc8

yum update -y && yum install -y centos-release-scl
yum install -y bison wget bzip2 gcc gcc-c++ glibc-headers nss-devel

2.2.升级make

wget http://ftp.gnu.org/gnu/make/make-4.2.1.tar.gz
tar -zxvf make-4.2.1.tar.gz
mkdir make-4.2.1/build && cd make-4.2.1/build
../configure --prefix=/usr/local/make && make -j4 && make install
export PATH=/usr/local/make/bin:$PATH
ln -s /usr/local/make/bin/make   /usr/local/make/bin/gmake
make -v

2.3.升级GCC

yum install -y devtoolset-8-gcc devtoolset-8-gcc-c++ devtoolset-8-binutils
echo "source /opt/rh/devtoolset-8/enable" | tee -a /etc/profile
source /etc/profile
gcc -v

2.4.下载并安装Glibc

wget https://ftp.gnu.org/gnu/glibc/glibc-2.28.tar.xz
xz -d glibc-2.28.tar.xz && tar -xvf glibc-2.28.tar
mkdir glibc-2.28/build && cd glibc-2.28/build
…/configure --prefix=/usr --with-headers=/usr/include
–with-binutils=/usr/bin --disable-profile --enable-add-ons

…/configure --prefix=/usr
–with-headers=/usr/include
–with-binutils=/usr/bin
–enable-add-ons
–enable-obsolete-nsl
–disable-profile
–disable-sanity-checks
–disable-werror

make -j4
make install

strings /lib64/libc.so.6 | grep ^GLIBC_2.28

3.更新libstdc++.so.6.0.26

# 更新lib libstdc++.so.6.0.26
wget http://www.vuln.cn/wp-content/uploads/2019/08/libstdc.so_.6.0.26.zip
# 解压
unzip libstdc.so_.6.0.26.zip
# 替换系统中的/usr/lib64
# 把下载的libstdc++.so.6.0.26 cp 到 /usr/lib64/
ll /usr/lib64/libstdc++.so.6
mv libstdc++.so.6.0.26 /usr/lib64/
cd /usr/lib64/
ln -snf ./libstdc++.so.6.0.26 libstdc++.so.6
