CentOS 7 系统下mysql 8.0安装方法

从mysql官网获取下载链接

https://cdn.mysql.com/archives/mysql-8.0/mysql-8.0.28-1.el7.x86_64.rpm-bundle.tar

通过wget命令下载

wget https://cdn.mysql.com/archives/mysql-8.0/mysql-8.0.28-1.el7.x86_64.rpm-bundle.tar

通过tar命令解压

tar -vxf mysql-8.0.28-1.el7.x86_64.rpm-bundle.tar

安装之前必须把系统自带的安装包或者以前安装过包清楚掉，否则会安装失败

依次安装以下包（必须按顺序安装）：

rpm -ivf mysql-community-common-8.0.28-1.el7.x86_64.rpm

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

rpm -ivf mysql-community-icu-data-files-8.0.28-1.el7.x86_64.rpm

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