1、安装包
## 查看系统版本
cat /etc/redhat-release
## 查看内核信息
cat /proc/version
MySQL官网提供了针对不同操作系统的客户端安装包
官网上选择需要安装的版本downloads.mysql.com/archives/co…
选择CentOS7版本，找到如下安装包，进行下载：
- mysql-community-client-8.0.30-1.el7.x86_64.rpm
- mysql-community-client-plugins-8.0.30-1.el7.x86_64.rpm
- mysql-community-common-8.0.30-1.el7.x86_64.rpm
- mysql-community-devel-8.0.30-1.el7.x86_64.rpm
- mysql-community-libs-8.0.30-1.el7.x86_64.rpm
2、安装
将rpm包上传服务器，并进行安装，--force --nodeps参数的作用是忽略依赖关系
- rpm -ivh mysql-community-client-8.0.30-1.el7.x86_64.rpm
- rpm -ivh mysql-community-client-plugins-8.0.30-1.el7.x86_64.rpm
- rpm -ivh mysql-community-common-8.0.30-1.el7.x86_64.rpm --force --nodeps
- rpm -ivh mysql-community-devel-8.0.30-1.el7.x86_64.rpm
- rpm -ivh mysql-community-libs-8.0.30-1.el7.x86_64.rpm --force --nodeps
3、验证版本
mysql --version
## mysql Ver 8.0.30 for Linux on x86_64 (MySQL Community Server - GPL)
