NAME
mysql_secure_installation - improve MySQL installation security
SYNOPSIS
mysql_secure_installation
DESCRIPTION
This program enables you to improve the security of your MySQL
installation in the following ways:
· You can set a password for root accounts.
· You can remove root accounts that are accessible from outside the
local host.
· You can remove anonymous-user accounts.
· You can remove the test database (which by default can be accessed
by all users, even anonymous users), and privileges that permit
anyone to access databases with names that start with test_.
mysql_secure_installation helps you implement security recommendations
similar to those described at Section 2.10.4, “Securing the Initial
MySQL Accounts”.
As of MySQL 5.7.2, mysql_secure_installation is an executable binary
available on all platforms. Before 5.7.2, it was a script available for
Unix and Unix-like systems.
Normal usage is to connect to the local MySQL server; invoke
mysql_secure_installation without arguments:
shell> mysql_secure_installation
When executed, mysql_secure_installation prompts you to determine which
actions to perform.
As of MySQL 5.7.2, mysql_secure_installation supports these additional
features:
· The validate_password plugin can be used for password strength
checking. If the plugin is not installed, mysql_secure_installation
prompts the user whether to install it. Any passwords entered later
are checked using the plugin if it is enabled.
· Most of the usual MySQL client options such as --host and --port
can be used on the command line and in option files. For example,
to connect to the local server over IPv6 using port 3307, use this
command:
shell> mysql_secure_installation --host=::1 --port=3307
mysql_secure_installation supports the following options, which can be
specified on the command line or in the [mysql_secure_installation] and
[client] groups of an option file. For information about option files
used by MySQL programs, see Section 4.2.6, “Using Option Files”.
· --help, -?
Display a help message and exit.
· --defaults-extra-file=file_name
Read this option file after the global option file but (on Unix)
before the user option file. If the file does not exist or is
otherwise inaccessible, an error occurs. file_name is interpreted
relative to the current directory if given as a relative path name
rather than a full path name.
· --defaults-file=file_name
Use only the given option file. If the file does not exist or is
otherwise inaccessible, an error occurs. file_name is interpreted
relative to the current directory if given as a relative path name
rather than a full path name.
· --defaults-group-suffix=str
Read not only the usual option groups, but also groups with the
usual names and a suffix of str. For example,
mysql_secure_installation normally reads the [client] and
[mysql_secure_installation] groups. If the
--defaults-group-suffix=_other option is given,
mysql_secure_installation also reads the [client_other] and
[mysql_secure_installation_other] groups.
· --host=host_name, -h host_name
Connect to the MySQL server on the given host.
· --no-defaults
Do not read any option files. If program startup fails due to
reading unknown options from an option file, --no-defaults can be
used to prevent them from being read.
The exception is that the .mylogin.cnf file, if it exists, is read
in all cases. This permits passwords to be specified in a safer way
than on the command line even when --no-defaults is used.
(.mylogin.cnf is created by the mysql_config_editor utility. See
mysql_config_editor(1).)
· --password=password, -p password
This option is accepted but ignored. Whether or not this option is
used, mysql_secure_installation always prompts the user for a
password.
· --port=port_num, -P port_num
The TCP/IP port number to use for the connection.
· --print-defaults
Print the program name and all options that it gets from option
files.
· --protocol={TCP|SOCKET|PIPE|MEMORY}
The connection protocol to use for connecting to the server. It is
useful when the other connection parameters normally would cause a
protocol to be used other than the one you want. For details on the
permissible values, see Section 4.2.2, “Connecting to the MySQL
Server”.
· --socket=path, -S path
For connections to localhost, the Unix socket file to use, or, on
Windows, the name of the named pipe to use.
· --ssl*
Options that begin with --ssl specify whether to connect to the
server using SSL and indicate where to find SSL keys and
certificates. See Section 6.3.12.4, “SSL Command Options”.
· --use-default
Execute noninteractively. This option can be used for unattended
installation operations. This option was added in MySQL 5.7.4.
· --user=user_name, -u user_name
The MySQL user name to use when connecting to the server.
