4.6.7 mysqlaccess — Client for Checking Access Privileges


This utility is deprecated in MySQL 5.6.17 and removed in MySQL 5.7

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. mysqlaccess checks access using only the user and db 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]

When mysqlaccess runs, it loads and executes the contents of its configuration file, mysqlaccess.conf. mysqlaccess looks for the configuration file in these locations, in order:

  • The directory named by the SYSCONFDIR option to CMake when MySQL was built. By default, this is the etc directory located under the compiled-in installation directory.

  • The /etc directory.

mysqlaccess supports the options shown in the following table.

Table 4.17 mysqlaccess Options

--user MySQL user name to use when connecting to server
--version 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.
