Reset WordPress admin/users password from Linux command line

How to reset WordPress admin/users password from Linux command line?

Ans: 

* Log into server as root.

* Enter to MySQL command prompt.

root@grand [~]# mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 932677

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

*  Verify user details from “wp_users” table.

We need to select only the following details from “wp_users” table.

mysql> SELECT ID, user_login, user_pass FROM wp_users;
+----+------------+------------------------------------+
| ID | user_login | user_pass                          |
+----+------------+------------------------------------+
|  1 | admin      | $P$BjUKUieEYT1B3TnkQHsv4Y8hfnSK5t. |
+----+------------+------------------------------------+
1 row in set (0.00 sec)

mysql> 

This WordPress has only one user “Admin”. The password displayed here isn’t real, it’s in MD5 encrypted format.

*  Updating user password.

This is the point that we are looking for. As I mentioned, the password displayed is in MD5 format. In latest MySQL versions we can generate the password in MD5 format from the commandline itself. Please see the syntax:

mysql> UPDATE wp_users SET user_pass = MD5(‘WPEXPLORER’) WHERE ID=1 LIMIT 1;

In previous versions we have to enter the password in MD5 format.

Syntax to change the password

mysql> UPDATE wp_users SET user_pass = "61250b88abfe298f2df4821d081a3add"  WHERE ID=1;

Here the user pass in MD5 format.

See the updated password:

mysql> SELECT ID, user_login, user_pass FROM wp_users;
+----+------------+----------------------------------+
| ID | user_login | user_pass                        |
+----+------------+----------------------------------+
|  1 | admin      | 61250b88abfe298f2df4821d081a3add |
+----+------------+----------------------------------+
1 row in set (0.00 sec)

mysql> 

That’s it!! Now try to login with the new password.
