2、使用yum进行安装

yum -y install mysql80-community-release-el7-1.noarch.rpm

3、安装mysql

4、启动mysql

systemctl start mysqld.service

systemctl status mysqld.service

6、查看root用户名密码

grep "passsword" /var/log/mysqld.log

7、登录mysql数据库

mysql -uroot -p 输入密码进入数据库

8、修改root密码

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password';

9、卸载Yum Repository

yum -y remove mysql80-community-release-el7-1.noarch

10、设置开机启动

shell> systemctl daemon-reload

11、创建用户，添加远程登录

创建用户
mysql>create user 用户名@'%' identified  by '密码';
