Reset password user ‘root’ di MySQL Server maupun MariaDB Server

Lupa adalah hal yg wajar sebagai manusia, lupa bisa menjadi berkah dan sebaliknya bisa jadi bencana lho, apalagi yg menyandang status sysadmin… hehehe. :D

Ok, hari ini saya akan menuliskan catatan dan berbagi pengalaman. Cara mereset password root database MySQL maupun MariaDB.

Langsung saja:

1. Langkah pertama, stop service daemon ‘mysqld’ untuk MySQL server dan ‘mysql’ untuk MariaDB.

[root@server ~]# service mysqld stop
Stopping mysqld:  [  OK  ]

2. Jalankan lagi service mysql daemon secara ‘safe mode’, kemudian tkan tombol ctrl+c untuk kembali ke shell (dengan menekan tombol ctrl+c, secara harfiah kita telah menggagalkan suatu proses, tapi dalam kasus ini, service mysql masih berjalan kok).

[root@server ~]# mysqld_safe --skip-grant-tables --skip-networking &
[1] 12731
[root@server ~]# 130204 20:00:06 mysqld_safe Logging to '/var/log/mysqld.log'.
130204 20:00:06 mysqld_safe A mysqld process already exists
^C
[1]+  Exit 1

# note: dengan opsi --skip-grant-tables, berarti telah memperbolehkan login ke shell sql tanpa pengecekan password. Dan ini tidak aman, sehingga kita perlu menambahkan opsi --skip-networking, untuk mencegah query dari jaringan.

3. Dan kitapun berhasil masuk ke shell MySQL/ MariaDB tanpa password :).

[root@server ~]# mysql -u root

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> show databases;
+--------------------+

| mysql              |
| test               |

4. Setelah berhasil masuk ke shell MySQL/ MariaDB, kita bisa melakukan update password ke user yg kita inginkan, terutama user ‘root’.

mysql> update mysql.user set password = password('satudua3') where user='root';
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3  Changed: 3  Warnings: 0

mysql> use mysql;

You can turn off this feature to get a quicker startup with -A

Database changed
mysql> select user,password,host from user;
+------+-------------------------------------------+-----------+
| user | password                                  | host      |
+------+-------------------------------------------+-----------+
| root | *200CFA46F92231BE79458247DEA35133DFFA3608 | localhost |
| root | *200CFA46F92231BE79458247DEA35133DFFA3608 | server    |
| root | *200CFA46F92231BE79458247DEA35133DFFA3608 | 127.0.0.1 |
+------+-------------------------------------------+-----------+
5 rows in set (0.00 sec)

mysql> \q
Bye

5. Selanjutnya, lakukan restart kepada service ‘mysqld’ untuk MySQL server atau ‘mysql’ untuk MariaDB server daemon.

[root@server ~]# service mysqld restart
Stopping mysqld:  [  OK  ]
Starting mysqld:  [  OK  ]

6. Pastikan mysql daemon sudah bekerja dengan benar.

[root@server ~]# mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO) ## Akses dilarang karena tidak menyertakan password

[root@server ~]# mysql -u root -p
Enter password: ******* ## password mysql, dan kita pun bisa login.
