Removing User Accounts; Setting Account Resource Limits - Oracle 5.0 Reference Manual

mysql> CREATE USER 'myname'@'%.mydomain.com' IDENTIFIED BY 'mypass';
To do the same thing by modifying the grant tables directly, do this:
mysql> INSERT INTO user (Host,User,Password,...)
->
mysql> FLUSH PRIVILEGES;

6.3.4. Setting Account Resource Limits

One means of limiting use of MySQL server resources is to set the global
max_user_connections
simultaneous connections that can be made by any given account, but places no limits on what
a client can do once connected. In addition, setting
enable management of individual accounts. Both types of control are of interest to many MySQL
administrators, particularly those working for Internet Service Providers.
In MySQL 5.0, you can limit use of the following server resources for individual accounts:
• The number of queries that an account can issue per hour
• The number of updates that an account can issue per hour
• The number of times an account can connect to the server per hour
• The number of simultaneous connections to the server by an account (available as of MySQL 5.0.3)
Any statement that a client can issue counts against the query limit (unless its results are served from
the query cache). Only statements that modify databases or tables count against the update limit.
An "account" in this context corresponds to a row in the
assessed against the
example, an account
and
User Host
the
example.com
connections by
the same account.
Before MySQL 5.0.3, an "account" was assessed against the actual host from which a user connects.
This older method accounting may be selected by starting the server with the

limits
host2.example.com, the server applies the account resource limits separately to each connection.
If connects again from host1.example.com, the server applies the limits for that connection
usera
together with the existing connection from that host.
To set resource limits for an account, use the
Syntax"). Provide a
limit is zero (no limit). For example, to create a new account that can access the
but only in a limited fashion, issue these statements:
mysql> CREATE USER 'francis'@'localhost' IDENTIFIED BY 'frank';
mysql> GRANT ALL ON customer.* TO 'francis'@'localhost'
