Linux环境下安装部署MySQL数据库

YUM在线安装
1、下载并安装MySQL官方的 Yum Repository

[root@localhost ~]# dnf install https://repo.mysql.com//mysql80-community-release-el9-1.noarch.rpm
 2、直接安装mysql-server

[root@localhost ~]# dnf install mysql-server
3、启动服务

[root@localhost ~]# systemctl start mysqld.service
4、查看临时密码

[root@localhost ~]# grep 'temporary password' /var/log/mysqld.log
5、使用临时密码进行登录

[root@localhost ~]# mysql -uroot -p
Enter password: 临时密码

6、修改密码

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';
更改之后，则可以使用新密码登录。

如果没有找到日志文件，则可以查找 /var/log/mysql/mysqld.log，如果没有密码，则默认是空密码。
