| # MySQL Create Restricted User
MySQL privileges allow each of the users to access and utilize only the areas they need to perform their tasks. This prevents a user from accidentally accessing an area where he or she should not have access, adding to the security of the MySQL server. When you connect to a MySQL server, the host from which you connect and the username you specify determines your identity. With this information, the server then grants privileges based upon this identity. This page focuses on creating a user with restricted privileges. There are three methods for creating a restricted user; you can use UniController, phpMyAdmin or MySQL Console. UniController provides a convenient menu option described below. To use this option, ensure the MySQL server is running; otherwise, the button remains greyed out. ## Create Restricted MySQL User using UniController MySQL > Create restricted MySQL User
Enter a user name (1), e.g. fred. Enter the user password (2), e.g. fred123. Select a database from the list (3) to assign to the user. ◦ The database name (4) is automatically inserted. ◦ Alternatively, you can manually enter a database name (4). Select or deselect primary user privileges (5) as required. Click Create User (6). Note 1: Cancel (7) clears both the selected database and user input. Note 2: You can manually enter a database (4) even if it does not exist. The database is assigned to the user, and it is assumed you will create this database later. |  |
## Create Restricted MySQL User using phpMyAdmin Start Controller and start both servers, then click phpMyAmin button. To create a restricted user, proceed as follows: Note: The following assumes the user to create is mike123 and the password is pass123. The database wordpress that the user will be assigned to must have already been created. ### Open Add new user page
When first started, the phpMyAdmin home page is displayed; you can always return to this page by clicking the Home icon (1). If not at the home page, click Home icon (1). From the top menu bar, select User accounts (2). Click Add a new User (3). The Add user account page is displayed. |  |
### Create new user
Creating a new user requires only the login information; the other fields are not required. We will assign this user to a database and set appropriate privileges as a second step. From Add user account page: Enter user name (4); example mike123. From the Host name drop down menu, select Use text field. Enter 127.0.0.1 (5). This user is restricted to the IPv4 address for localhost. Enter password (6); example pass123. Re-type password (7) as entered above. Click Go (8); confirmation produced. Note: Leave all other fields set to their defaults: Database for user account: None selected Global privileges: all boxes Uncheck Resource limits: all values set to 0 |  |
### Assign user to a database The new user created has now been added to the User accounts overview page. This new entry allows a user to be assigned to a database as follows:
After creating a new user, you will be at the Edit privileges: User account page. If not on Edit privileges: User account page, from Home menu, select User accounts (9). Click Edit Privileges (10) for user mike123. |  |
A new page opens, displaying privileges. From the top menu bar, select Databases. From the Database-specific privileges section, select the database wordpress (11) and click Go. |  |
This directs you to the Database-specific privileges section. Select the privileges required (12-13) for your restricted user. Click Go (14); this assigns the user to the database with the privileges selected. |  |
## Create Restricted MySQL User using MySQL Console Creating a user with restricted privileges and assigning that user to an existing database can also be performed using a single SQL line. Example user User name to create: fred123 User password: fredpass Existing database: wordpress Open MySQL Console: click MySQL Console button. Use the MySQL Client utility to create our example user with restricted privileges as follows:
`GRANT SELECT, INSERT, UPDATE, DELETE ON wordpress.* TO 'fred123'@'127.0.0.1' IDENTIFIED BY 'fredpass';` `exit` The result is shown below:
    Welcome to the MySQL monitor.  Commands end with ; or \g.

    Query OK, 0 rows affected (0.02 sec)

    mysql> exit
    Bye

    C:\UniServerZ\core\mysql\bin>
Note: If you have changed the MySQL root password, remember to substitute root (-proot) with your password in the above. ## Delete Restricted MySQL User using MySQL Console Delete a user (example: fred123) with restricted privileges as follows: Open MySQL Console: click MySQL Console button. Use the MySQL Client utility to delete our example user fred123:
Enter the following in a command window: `DROP USER 'fred123'@'127.0.0.1';` `exit` The result is shown below:
