linux CentOS7安装MySQL8.0.28

1.查看系统中是否有会冲突的数据库

CentOS 7.6 默认有个mariadb数据库会和 mysql 冲突

查询命令

rpm -qa|grep mari

mariadb-libs-5.5.68-1.el7.x86_64

删除

rpm -e --nodeps mariadb-libs

rpm -e --nodeps marisa

2.用wget 命令下载安装包

3.用 tar 命令解压

4.用rpm命令安装,注意安装顺序,这个很重要.

rpm -ivh mysql-community-client-8.0.28-1.el7.x86_64.rpm

rpm -ivh mysql-community-client-plugins-8.0.28-1.el7.x86_64.rpm

rpm -ivh mysql-community-server-8.0.28-1.el7.x86_64.rpm

5.初始化
