MySQL Database System MYSQL_SECURE_INSTALLATION(1)
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:
o You can set a password for root accounts.
o You can remove root accounts that are accessible from outside the
local host.
o You can remove anonymous-user accounts.
o 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 Account".
Normal usage is to connect to the local MySQL server; invoke
mysql_secure_installation without arguments:
mysql_secure_installation
When executed, mysql_secure_installation prompts you to determine which
actions to perform.
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:
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 4.2.2.2, "Using Option Files".
o --help, -? Display a help message and exit.
o --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. If file_name is not an absolute path name, it is
interpreted relative to the current directory.
For additional information about this and other option-file
options, see Section 4.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --defaults-file=file_name Use only the given option file. If the
file does not exist or is otherwise inaccessible, an error occurs.
If file_name is not an absolute path name, it is interpreted
relative to the current directory.
For additional information about this and other option-file
options, see Section 4.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --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 this option is given as
--defaults-group-suffix=_other, mysql_secure_installation also
reads the [client_other] and [mysql_secure_installation_other]
groups.
For additional information about this and other option-file
options, see Section 4.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --host=host_name, -h host_name Connect to the MySQL server on the
given host.
o --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 is read in all cases,
if it exists. This permits passwords to be specified in a safer way
than on the command line even when --no-defaults is used. To create
.mylogin.cnf, use the mysql_config_editor utility. See
mysql_config_editor(1).
For additional information about this and other option-file
options, see Section 4.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --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.
o --port=port_num, -P port_num For TCP/IP connections, the port
number to use.
o --print-defaults Print the program name and all options that it
gets from option files.
For additional information about this and other option-file
options, see Section 4.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --protocol={TCP|SOCKET|PIPE|MEMORY} The transport protocol to use
for connecting to the server. It is useful when the other
connection parameters normally result in use of a protocol other
than the one you want. For details on the permissible values, see
Section 4.2.5, "Connection Transport Protocols".
o --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.
On Windows, this option applies only if the server was started with
the named_pipe system variable enabled to support named-pipe
connections. In addition, the user making the connection must be a
member of the Windows group specified by the
named_pipe_full_access_group system variable.
o --ssl* Options that begin with --ssl specify whether to connect to
the server using encryption and indicate where to find SSL keys and
certificates. See the section called "Command Options for Encrypted
Connections".
o --tls-version=protocol_list The permissible TLS protocols for
encrypted connections. The value is a list of one or more
comma-separated protocol names. The protocols that can be named for
this option depend on the SSL library used to compile MySQL. For
details, see Section 6.3.2, "Encrypted Connection TLS Protocols and
Ciphers".
This option was added in MySQL 5.7.10.
o --use-default Execute noninteractively. This option can be used for
unattended installation operations.
o --user=user_name, -u user_name The user name of the MySQL account
to use for connecting to the server.
