導讀 | 本文檔詳細介紹破解 MySQL5.7 數據庫的 root 登錄密碼 |
忘記 root 登錄密碼
[root@MySQL1 ~]# mysql -uroot -p1231234 mysql: [Warning] Using a password on the command line interface can be insecure. ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
在 /etc/my.cnf 配置文件中添加 skip-grant-tables 繞開 MySQL5.7 數據庫密碼驗證
[root@MySQL1 ~]# echo skip-grant-tables >> /etc/my.cnf [root@MySQL1 ~]# /etc/init.d/mysqld restart Shutting down MySQL.. SUCCESS! Starting MySQL. SUCCESS!
直接使用 mysql 命令登錄 MySQL5.7 數據庫并修改 root 登錄密碼
[root@MySQL1 ~]# mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 Server version: 5.7.19-log Source distribution Copyright (c) 2000, 2017, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'password'; ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'password'; Query OK, 0 rows affected (0.00 sec) mysql> quit Bye
注意:如果在執行該步驟的時候出現 ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement 錯誤。則執行下 flush privileges; 命令,再執行該命令即可。
使用新密碼 password 登錄 MySQL5.7 數據庫
[root@MySQL1 ~]# mysql -uroot -ppassword mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 4 Server version: 5.7.19-log Source distribution Copyright (c) 2000, 2017, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> exit Bye
使用其他密碼不能登錄 MySQL5.7 數據庫
[root@MySQL1 ~]# mysql -uroot -ppasswordd mysql: [Warning] Using a password on the command line interface can be insecure. ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
優化
刪掉 /etc/my.cnf 里的 skip-grant-tables
[root@MySQL1 ~]# sed -i -e '/skip-grant-tables/d' /etc/my.cnf
重啟數據庫
[root@MySQL1 ~]# /etc/init.d/mysqld restart
