yum基础源调整
备份原文件
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak
调整为阿里云源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum scl源调整
vi /etc/yum.repos.d/CentOS-SCLo-scl.repo
[centos-sclo-sclo]
name=CentOS-7 - SCLo sclo
baseurl=https://mirrors.aliyun.com/centos/7/sclo/x86_64/sclo/
# mirrorlist=http://mirrorlist.centos.org?arch=$basearch&release=7&repo=sclo-sclo
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-SCLo
vi /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo
[centos-sclo-rh]name=CentOS-7 - SCLo rh
baseurl=https://mirrors.aliyun.com/centos/7/sclo/x86_64/rh/
# mirrorlist=http://mirrorlist.centos.org?arch=$basearch&release=7&repo=sclo-rh

刷新cache
yum repolist
yum clean all
yum makecache
操作流程
https://roy.wang/centos7-upgrade-glibc/
默认的GCC 版本无法无法编译 Glibc 2.28。 安装GLIBC所需的依赖，该版本需要 GCC 4.9 以上 及 make 4.0 以上。 GCC 11.2版本太新，无法与Glibc 2.28兼容。
一、安装gcc-8.2.0所依赖的环境
yum install bison -y
yum -y install wget bzip2 gcc gcc-c++ glibc-headers
二、升级GNU Make 3.82到4.2.1
wget http://ftp.gnu.org/gnu/make/make-4.2.1.tar.gz
tar -zxvf make-4.2.1.tar.gz
cd make-4.2.1
mkdir build
cd build
../configure --prefix=/usr/local/make && make && make install
export PATH=/usr/local/make/bin:$PATH
ln -s /usr/local/make/bin/make /usr/local/make/bin/gmake
make -v
三、升级GCC
yum install -y devtoolset-8-gcc devtoolset-8-gcc-c++ devtoolset-8-binutils
echo "source /opt/rh/devtoolset-8/enable" >> /etc/profile
source /etc/profile
四、下载 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
cd glibc-2.28
mkdir build
五、编译安装 Glibc
cd build
../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
make -j4
make install
六、查询支持的 Glibc
strings /lib64/libc.so.6 | grep GLIBC
