3.启动mysql
[root@bigdata-senior02 mysql]# systemctl start mysqld
[root@bigdata-senior02 mysql]#
4.初始化数据库
mysqld --initialize
5.查看数据库密码
[root@bigdata-senior02 mysql]# grep passwd /var/log/mysqld.log [root@bigdata-senior02 mysql]# grep password /var/log/mysqld.log 2021-04-24T09:40:08.666303Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: z9Fkgh/,ZDx+ [root@bigdata-senior02 mysql]#
6.登陆、重置root密码
