yum install mysql80-community-release-el7-3.noarch.rpm
#检查Yum 仓库是否创建成功
yum repolist enabled | grep "mysql.*-community.*"

2. 安装MySQL

yum install mysql-community-server

3. 启动MySQL

systemctl start mysqld

4. 查看MySQL状态

systemctl status mysqld

5. 查找密码

sudo grep 'temporary password' /var/log/mysqld.log

6. 修改密码

shell>shell> mysql -uroot -p
#输入密码进入MySQL
#通过以下语句修改密码
mysql>ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';

7. 开启可以远程连接

#进入MySQL,使用mysql数据库
mysql> use mysql;
#查看root用户的host
mysql> select host from user where user='root';
#修改root用户的host为%
mysql> update user set host='%' where user='root';
#刷新MySQL配置
mysql> flush privileges;

至此，即可连接Linux上的MySQL。
