## How to change user password on mysql
|
|
|
|
Mysql change user password using the following method:
|
|
|
|
1. Open the bash shell and connect to the server as root user:
|
|
**mysql -u root -h localhost -p**
|
|
2. Run ALTER mysql command:
|
|
**ALTER USER 'userName'@'localhost' IDENTIFIED BY 'New-Password-Here';**
|
|
3. Finally type SQL command to reload the grant tables in the mysql database:
|
|
FLUSH PRIVILEGES;
|
|
|
|
Please note that use mysql.exe on MS-Windows host as follows (first change directory where mysql.exe is located \[example: “C:\\Program Files\\mysql\\mysql-5.0.77-win32\\bin“\]. Let us see examples and syntax in details.
|
|
|
|
## mysql command to change a user password
|
|
|
|
Login as root from the shell:
|
|
`$ mysql -u root -p`
|
|
Or admin user that can do DBA duties. For example:
|
|
`$ mysql -u admin -h 10.83.200.253 -p`
|
|
Where,
|
|
|
|
- \-u root OR \-u admin : MySQL server admin user name (root is default on most systems).
|
|
- \-h 10.83.200.253 : MySQL server IP address or hostname such as server1.cyberciti.biz.
|
|
- \-p : Prompt for the password.
|
|
|
|
Switch to mysql database (type command at mysql> prompt, do not include string “mysql>”):
|
|
`mysql> **use mysql;**`
|
|
The syntax is as follows for **mysql database server version 5.7.5** or older:
|
|
|
|
SET PASSWORD FOR 'user-name-here'@'hostname' \= PASSWORD('new-password');
|
|
|
|
For **mysql database server version 5.7.6 or newer** use the following syntax:
|
|
|
|
ALTER USER 'user'@'hostname' IDENTIFIED BY 'newPass';
|
|
|
|
You can also use the following sql syntax:
|
|
|
|
UPDATE mysql.user SET Password\=PASSWORD('new-password-here') WHERE USER\='user-name-here' AND Host\='host-name-here';
|
|
|
|
In this example, change a password for a user called tom:
|
|
|
|
SET PASSWORD FOR 'tom'@'localhost' \= PASSWORD('foobar');
|
|
|
|
OR
|
|
|
|
UPDATE mysql.user SET Password\=PASSWORD('foobar') WHERE USER\='tom' AND Host\='localhost';
|
|
|
|
Sample outputs:
|
|
|
|
Query OK, 1 row affected (0.00 sec)
|
|
Rows matched: 1 Changed: 1 Warnings: 0
|
|
|
|
Feel free to replace the values for “tom” (user), “localhost” (hostname), and “foobar” (password) as per your requirements. Finally, type the following command to reload privileges:
|
|
|
|
Sample outputs:
|
|
|
|
Query OK, 0 rows affected (0.00 sec)
|
|
|
|
To exit from mysql> prompt, enter:
|
|
|
|
## Changing the MySQL root or user password using the mysqladmin command
|
|
|
|
We can also use the mysqladmin CLI to alter the MySQL password. The syntax for the mysqladmin command is as follows:
|
|
`$ mysqladmin --user={USER_NAME} password "{NEW_PASSWORD_HERE}" $ mysqladmin --user=root password "5b350f65542fdb74e74ef7b815f86ad5" $ mysqladmin --user=root --host=192.168.2.200 --password password "5b350f65542fdb74e74ef7b815f86ad5"`
|
|
Where,
|
|
|
|
- \--user=root : User for login if not current user.
|
|
- \--password : Prompt for password to use when connecting to server.
|
|
- \--host=192.168.2.200 : Connect to MySQL server host by given IP address or hostname.
|
|
- password "5b350f65542fdb74e74ef7b815f86ad5" : Change old password to “5b350f65542fdb74e74ef7b815f86ad5” in current format.
|
|
|
|
### Verify the new password settings
|
|
|
|
User or you can test new password using the following shell syntax:
|
|
`$ mysql -u tom -p`
|
|
When promoted enter new password you set earlier for tom user.
