解决centos7 安装 mysql8 Requires: libstdc++.so.6(GLIBCXX_3.4.21)(64bit)....的常见坑

对应版本的库明明存在，mysql与centos版本也对应，但是就是提示Requires [root@11 mysql]# yum install mysql-community-server Loaded plugins: fastestmirror Setting up Install Process Loading mirror speeds from cached hostfile

libmysqlclient.so.16(libmysqlclient_16)(64bit) 2:postfix-2.6.6-8.el6.x86_64 has missing requires of mysql-libs 原因及办法：我第一次安装成了el8的mysql-server，卸载之后，yum没有clean。

1、yum update （可选）
2、rpm -qa|grep mysql #找到已装的rpm包名
3、rpm -e 包名 #卸载
4、yum clean all #清缓存 关键！！
