使用命令检查MySQL数据库是否已经关闭:
1 [root@localhost ~]# systemctl status mysql
出现“Active: inactive (dead)”表示数据库已关闭,如果是“Active: active (exited)”表示已开启,需要手动关闭:
1 [root@localhost ~]# systemctl stop mysql
找到MySQL的配置文件“my.cnf”,默认路径是:“/etc/my.cnf”。
打开文件并在“[mysqld]”下添加:
1 skip-grant-tables
这句话的作用是在登录MySQL的时候可以跳过密码直接登录。
保存修改并退出。
使用命令启动MySQL:
1 [root@localhost ~]# systemctl start mysql
输入“mysql”即可进入数据库。
连接“mysql”数据库,修改用户密码:
1 mysql> use mysql; 2 Reading table information for completion of table and column names 3 You can turn off this feature to get a quicker startup with -A 4 5 Database changed 6 mysql> update mysql.user set password=password(‘123456‘) where user=‘root‘; 7 Query OK, 5 rows affected (0.00 sec) 8 Rows matched: 5 Changed: 5 Warnings: 0 9 10 mysql>
将root用户的密码设为123456。
刷新使改动生效:
1 mysql> flush privileges; 2 Query OK, 0 rows affected (0.00 sec)
退出MySQL,重新打开“my.cnf”配置文件,删除“skip-grant-tables”,保存退出。
重启MySQL,需要密码登录,输入设置的密码即可:
1 [root@localhost ~]# vim /etc/my.cnf 2 [root@localhost ~]# systemctl restart mysql 3 [root@localhost ~]# mysql 4 ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: NO) 5 [root@localhost ~]# mysql -u root -p 6 Enter password: 7 Welcome to the MySQL monitor. Commands end with ; or \g. 8 Your MySQL connection id is 4 9 Server version: 5.6.45 MySQL Community Server (GPL) 10 11 Copyright (c) 2000, 2019, Oracle and/or its affiliates.
