mysqlaccess − client for checking access privileges
|
mysqlaccess [host_name [user_name [db_name]]] [options] |
mysqlaccess is a diagnostic tool that Yves Carlier has provided for the MySQL distribution. It checks the access privileges for a hostname, username, 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 understands 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 hostname 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, you are prompted for one.
Specifying a password on the command line should be considered insecure. See Section 6.6, “Keeping Your Password Secure”.
|
• |
−−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 −−password or −p option on the command line, you are prompted for one.
Specifying a password on the command line should be considered insecure. See Section 6.6, “Keeping Your Password Secure”.
|
• |
−−superuser=user_name, −U user_name |
Specify the username for connecting as the superuser.
|
• |
−−table, −t |
Generate reports in table format.
|
• |
−−user=user_name, −u user_name |
The username to use in the access privileges.
|
• |
−−version, −v |
Display version information and exit.
If your MySQL distribution is installed in some non−standard 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.
