1. First update the yum source to Ali's
// 看当前的Centos系统是哪个版本的就选择对应的版本安装，这里以Centos8为例
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo
2. Modify the content of the centos file
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*3. Generate cache updates
yum clean all
yum makecacheIf you get this error: Failed to set locale, defaulting to C.UTF-8
Execute the following two commands to solve the problem, and then regenerate the cache update
echo "export LC_ALL=en_US.UTF8" >> /etc/profile
source /etc/profile4. Run yum update
yum update -y5. Reinstall the C++ library, there should be no error
yum install glibc-headers
yum install gcc-c++At this time, go to the software store to install the corresponding php version should be normal~
