基于CentOS上安装ScyllaDB数据库的朋友应该都会遇到glibc必须为2.28及以上版本的问题，哈目前阿里去上提供的最高版本CentOS7.6中的glibc版本为2.27，所以必须要升级，但升级glibc并不是一件容易的事，如果操作不当还会影响一些API和服务的正常运行，所以在升级之前请先做好备份。
升级前的准备工作：
1、升级gcc到9.2.0（请参考我的另一遍博文[https://yq.aliyun.com/articles/718551?spm=a2c4e.11155435.0.0.47163312EbbvoU](《》)）
2、安装Python3.8.0
3、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=/opt/make && make && make install

The script has found some problems with your installation!
Please read the FAQ and the README file and check the following:
- Did you change the gcc specs file (necessary after upgrading from
Linux libc5)?
- Are there any symbolic links of the form libXXX.so to old libraries?
Links like libm.so -> libm.so.5 (where libm.so.5 is an old library) are wrong,
libm.so should point to the newly installed glibc file - and there should be
only one such link (check e.g. /lib and /usr/lib)
You should restart this script from your build directory after you've
fixed all problems!
Btw. the script doesn't work if you're installing GNU libc not as your
primary library!
