5.启动MySQL数据库服务：
[root@node213 ~]# systemctl start mysqld
6.查看MySQL数据库生成的临时root登录密码：
[root@node213 ~]# cat /var/log/mysqld.log | grep password
2024-01-22T01:48:55.593788Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: /4Zm_4ljMyxj
7.通过临时密码登录数据库：
临时密码为：/4Zm_4ljMyxj
[root@node213 ~]# mysql -uroot -p'/4Zm_4ljMyxj' -hlocalhost
mysql: [Warning] Using a password on the command line interface can be insecure.

8.登录数据库后，要修改root密码：
mysql> alter user root@localhost identified by 'Rscpass123_';
9.查看数据库的版本：
mysql> select version();

10.如果想免密登录数据库，可以在my.cnf文件中这样配置：
在my.cnf文件最后面添加以下行：
[mysql]
user=root
password=Rscpass123_
保存后就可以直接通过mysql登录数据库了，不需要重启哈
[root@node213 ~]# mysql

这种方法对于测试环境还是很有用哈，在8.0之后，有个操作系统验证的插件，可以实现一样的功能，这个下次再分享哈
至此，MySQL-8.3.0最新创新版本安装配置完成，8.3.0版本也有很多新功能哦，一起体验一下哈。。。
