description
mysqlaccess
is a diagnostic tool that Yves Carlier has provided for the
MySQL distribution. It checks the access privileges for a
host name, user name, and database combination. Note that
mysqlaccess checks access using only the user, db,
and host tables. It does not check table, column, or routine
privileges specified in the tables_priv, columns_priv, or
procs_priv tables.
Invoke
mysqlaccess like this:
shell>
mysqlaccess [host_name
[user_name [db_name]]]
[options]
mysqlaccess
supports the following options.
•
--help, -?
Display a help
message and exit.
•
--brief, -b
Generate
reports in single-line tabular format.
•
--commit
Copy the new
access privileges from the temporary tables to the original
grant tables. The grant tables must be flushed for the new
privileges to take effect. (For example, execute a
mysqladmin reload command.)
•
--copy
Reload the
temporary grant tables from original ones.
•
--db=db_name, -d
db_name
Specify the
database name.
•
--debug=N
Specify the
debug level. N can be an integer from 0 to 3.
•
--host=host_name, -h
host_name
The host name
to use in the access privileges.
•
--howto
Display some
examples that show how to use mysqlaccess.
•
--old_server
Assume that the
server is an old MySQL server (before MySQL 3.21) that does
not yet know how to handle full WHERE clauses.
•
--password[=password],
-p[password]
The password to
use when connecting to the server. If you omit the
password value following the
--password or -p option on
the command line, mysqlaccess prompts for one.
Specifying a
password on the command line should be considered insecure.
See Section 6.1.2.1, “End-User Guidelines for
Password Security”.
•
--plan
Display
suggestions and ideas for future releases.
•
--preview
Show the
privilege differences after making changes to the temporary
grant tables.
•
--relnotes
Display the
release notes.
•
--rhost=host_name, -H
host_name
Connect to the
MySQL server on the given host.
•
--rollback
Undo the most
recent changes to the temporary grant tables.
•
--spassword[=password],
-P[password]
The password to
use when connecting to the server as the superuser. If you
omit the password value following the
--spassword or -p option on
the command line, mysqlaccess prompts for one.
Specifying a
password on the command line should be considered insecure.
See Section 6.1.2.1, “End-User Guidelines for
Password Security”.
•
--superuser=user_name,
-U user_name
Specify the
user name for connecting as the superuser.
•
--table, -t
Generate
reports in table format.
•
--user=user_name, -u
user_name
The user name
to use in the access privileges.
•
--version, -v
Display version
information and exit.
If your MySQL
distribution is installed in some nonstandard location, you
must change the location where mysqlaccess expects to
find the mysql client. Edit the mysqlaccess script at
approximately line 18. Search for a line that looks like
this:
$MYSQL =
'/usr/local/bin/mysql'; # path to mysql executable
Change the path
to reflect the location where mysql actually is
stored on your system. If you do not do this, a Broken pipe
error will occur when you run mysqlaccess.
