MySQL “users” FAQ: How do I add a new user to a MySQL database (i.e., how do I create a MySQL user account, and then grant database permissions to that new user account)?
Solution: MySQL add user and grant syntax
Here’s an example of what I did recently to (a) create a new MySQL database and then (b) add a new MySQL user account to work with that database.
Step 1: Log in to the database
First, from my Unix prompt, I logged into my MySQL database server with the mysql command line client:
unix> mysql -u root -p (here I enter 'my_root_password' to get through the mysql prompt)
Step 2: Create the database (if needed)
Next, I create my new database with the MySQL
create database command, specifying the name of the database (
my_database) after that command:
mysql> create database my_database;
Step 3: Create the new MySQL user account
Then I create a new MySQL user account, giving the user account all the priviliges it needs to “own” this database with the
grant command. Note that I assign both the username and password when I add the new user account:
mysql> GRANT ALL PRIVILEGES ON my_database.* TO 'my_user'@'localhost' IDENTIFIED BY 'my_password' WITH GRANT OPTION;
grant command is a little easier to copy and paste from:
GRANT ALL PRIVILEGES ON my_database.* TO 'my_user'@'localhost' IDENTIFIED BY 'my_password' WITH GRANT OPTION;
You can put that entire MySQL
grant command on one line; I just put it on multiple lines here so it would be easier to read. (It seems a little unusual, but using
grant is how you create a MySQL user account.)
Update: Please see the Comments section below for an additional "add user" example that uses the
Note about this MySQL user account and “localhost”
It's important to note when I create this MySQL user, I'm giving the user access to this MySQL database from the computer system known as "localhost". This works fine when you're accessing this database with this new MySQL user account from the local computer system, but if you're going to access this database from another computer system, you'll need to specify the IP address of that remote system here instead of "localhost".

I am a noob sysadmin, and this was very helpful.
I was just working on a new Bugzilla installation, and noticed their
grant command example, and thought I'd share it here as another example:
mysql> GRANT SELECT, INSERT, UPDATE, DELETE, INDEX, ALTER, CREATE, LOCK TABLES, CREATE TEMPORARY TABLES, DROP, REFERENCES ON bugs.* TO bugs@localhost IDENTIFIED BY '$db_pass'; mysql> FLUSH PRIVILEGES;
They also show this syntax for changing the MySQL
root user password, which is a little different than the syntax I normally use, so I thought I'd share that here as well:
mysql> UPDATE user SET password = password('new_password') WHERE user = 'root'; mysql> FLUSH PRIVILEGES;
I am also a noob sysadmin and this is very helpfull
