linux上安装MySQL8.0出现mariadb-libs is obsoleted错误

例如报错信息：

error: failed dependencies:

mariadb-libs is obsoleted by mysql-community-libs-8.0.18-1.el7.x86_64

原因：mariadb-libs和 mysql-community-libs冲突

解决办法：卸载mariadb-libs

a.查询mariadb-libs的包名

[root@marvin]# rpm -qa |grep mariadb
mariadb-libs-5.5.64-1.el7.x86_64

b.卸载该包

[root@marvin]# rpm -ev mariadb-libs-5.5.64-1.el7.x86_64
