下载rpm

安装 yum repo文件并更新 yum 缓存

rpm -ivh mysql80-community-release-el7-3.noarch.rpm　

执行结果：

会在/etc/yum.repos.d/目录下生成两个repo文件mysql-community.repo mysql-community-source.repo

执行

yum clean all
yum makecache

查看mysql yum仓库中mysql版本，使用如下命令
yum repolist all | grep mysql

安装

yum install mysql-community-server

启动mysql并获取初始密码

mysql配置

use mysql;
select user,host from user;
update user set host=‘%‘ where user=‘root‘;
ALTER USER ‘root‘@‘%‘ IDENTIFIED WITH mysql_native_password BY ‘abcd!123abcd;

‘root‘@‘%‘是个坑
