Create New User
Create a MySQL User
Section titled “Create a MySQL User”For creating new user, We need to follow simple steps as below :
Step 1: Login to MySQL as root
$ mysql -u root -pStep 2 : We will see mysql command prompt
mysql> CREATE USER 'my_new_user'@'localhost' IDENTIFIED BY 'test_password';Here, We have successfully created new user, But this user won’t have any permissions, So to assign permissions to user use following command :
mysql> GRANT ALL PRIVILEGES ON my_db.* TO 'my_new_user'@'localhost' identified by 'my_password';Specify the password
Section titled “Specify the password”The basic usage is:
mysql> CREATE USER 'my_new_user'@'localhost' IDENTIFIED BY 'test_password';However for situations where is not advisable to hard-code the password in cleartext it is also possible to specify directly, using the directive PASSWORD, the hashed value as returned by the PASSWORD() function:
mysql> select PASSWORD('test_password'); -- returns *4414E26EDED6D661B5386813EBBA95065DBC4728mysql> CREATE USER 'my_new_user'@'localhost' IDENTIFIED BY PASSWORD '*4414E26EDED6D661B5386813EBBA95065DBC4728';Create new user and grant all priviliges to schema
Section titled “Create new user and grant all priviliges to schema”grant all privileges on schema_name.* to 'new_user_name'@'%' identified by 'newpassword';Attention: This can be used to create new root user
Renaming user
Section titled “Renaming user”rename user 'user'@'%' to 'new_name`@'%';If you create a user by mistake, you can change his name
