NAME

6       mysql_secure_installation - improve MySQL installation security

SYNOPSIS

9       mysql_secure_installation
10

DESCRIPTION

12       This program enables you to improve the security of your MySQL
13       installation in the following ways:
14
15       ·   You can set a password for root accounts.
16
17       ·   You can remove root accounts that are accessible from outside the
18           local host.
19
20       ·   You can remove anonymous-user accounts.
21
22       ·   You can remove the test database (which by default can be accessed
23           by all users, even anonymous users), and privileges that permit
24           anyone to access databases with names that start with test_.
25
26       mysql_secure_installation helps you implement security recommendations
27       similar to those described at Section 2.10.4, “Securing the Initial
28       MySQL Account”.
29
30       Normal usage is to connect to the local MySQL server; invoke
31       mysql_secure_installation without arguments:
32
33           shell> mysql_secure_installation
34
35       When executed, mysql_secure_installation prompts you to determine which
36       actions to perform.
37
38       The validate_password component can be used for password strength
39       checking. If the plugin is not installed, mysql_secure_installation
40       prompts the user whether to install it. Any passwords entered later are
41       checked using the plugin if it is enabled.
42
43       Most of the usual MySQL client options such as --host and --port can be
44       used on the command line and in option files. For example, to connect
45       to the local server over IPv6 using port 3307, use this command:
46
47           shell> mysql_secure_installation --host=::1 --port=3307
48
49       mysql_secure_installation supports the following options, which can be
50       specified on the command line or in the [mysql_secure_installation] and
51       [client] groups of an option file. For information about option files
52       used by MySQL programs, see Section 4.2.2.2, “Using Option Files”.
53
54       ·   --help, -?
55
56           Display a help message and exit.
57
58       ·   --defaults-extra-file=file_name
59
60           Read this option file after the global option file but (on Unix)
61           before the user option file. If the file does not exist or is
62           otherwise inaccessible, an error occurs.  file_name is interpreted
63           relative to the current directory if given as a relative path name
64           rather than a full path name.
65
66           For additional information about this and other option-file
67           options, see Section 4.2.2.3, “Command-Line Options that Affect
68           Option-File Handling”.
69
70       ·   --defaults-file=file_name
71
72           Use only the given option file. If the file does not exist or is
73           otherwise inaccessible, an error occurs.  file_name is interpreted
74           relative to the current directory if given as a relative path name
75           rather than a full path name.
76
77           For additional information about this and other option-file
78           options, see Section 4.2.2.3, “Command-Line Options that Affect
79           Option-File Handling”.
80
81       ·   --defaults-group-suffix=str
82
83           Read not only the usual option groups, but also groups with the
84           usual names and a suffix of str. For example,
85           mysql_secure_installation normally reads the [client] and
86           [mysql_secure_installation] groups. If the
87           --defaults-group-suffix=_other option is given,
88           mysql_secure_installation also reads the [client_other] and
89           [mysql_secure_installation_other] groups.
90
91           For additional information about this and other option-file
92           options, see Section 4.2.2.3, “Command-Line Options that Affect
93           Option-File Handling”.
94
95       ·   --host=host_name, -h host_name
96
97           Connect to the MySQL server on the given host.
98
99       ·   --no-defaults
100
101           Do not read any option files. If program startup fails due to
102           reading unknown options from an option file, --no-defaults can be
103           used to prevent them from being read.
104
105           The exception is that the .mylogin.cnf file, if it exists, is read
106           in all cases. This permits passwords to be specified in a safer way
107           than on the command line even when --no-defaults is used.
108           (.mylogin.cnf is created by the mysql_config_editor utility. See
109           mysql_config_editor(1).)
110
111           For additional information about this and other option-file
112           options, see Section 4.2.2.3, “Command-Line Options that Affect
113           Option-File Handling”.
114
115       ·   --password=password, -p password
116
117           This option is accepted but ignored. Whether or not this option is
118           used, mysql_secure_installation always prompts the user for a
119           password.
120
121       ·   --port=port_num, -P port_num
122
123           For TCP/IP connections, the port number to use.
124
125       ·   --print-defaults
126
127           Print the program name and all options that it gets from option
128           files.
129
130           For additional information about this and other option-file
131           options, see Section 4.2.2.3, “Command-Line Options that Affect
132           Option-File Handling”.
133
134       ·   --protocol={TCP|SOCKET|PIPE|MEMORY}
135
136           The connection protocol to use for connecting to the server. It is
137           useful when the other connection parameters normally result in use
138           of a protocol other than the one you want. For details on the
139           permissible values, see Section 4.2.4, “Connecting to the MySQL
140           Server Using Command Options”.
141
142       ·   --socket=path, -S path
143
144           For connections to localhost, the Unix socket file to use, or, on
145           Windows, the name of the named pipe to use.
146
147           On Windows, this option applies only if the server was started with
148           the named_pipe system variable enabled to support named-pipe
149           connections. In addition, the the connection must be a member of
150           the Windows group specified by the named_pipe_full_access_group
151           system variable.
152
153       ·   --ssl*
154
155           Options that begin with --ssl specify whether to connect to the
156           server using SSL and indicate where to find SSL keys and
157           certificates. See the section called “Command Options for Encrypted
158           Connections”.
159
160       ·   --ssl-fips-mode={OFF|ON|STRICT} Controls whether to enable FIPS
161           mode on the client side. The --ssl-fips-mode option differs from
162           other --ssl-xxx options in that it is not used to establish
163           encrypted connections, but rather to affect which cryptographic
164           operations are permitted. See Section 6.5, “FIPS Support”.
165
166           These --ssl-fips-mode values are permitted:
167
168           ·   OFF: Disable FIPS mode.
169
170           ·   ON: Enable FIPS mode.
171
172           ·   STRICT: Enable “strict” FIPS mode.
173
174
175               Note
176               If the OpenSSL FIPS Object Module is not available, the only
177               permitted value for --ssl-fips-mode is OFF. In this case,
178               setting --ssl-fips-mode to ON or STRICT causes the client to
179               produce a warning at startup and to operate in non-FIPS mode.
180
181       ·   --tls-ciphersuites=ciphersuite_list
182
183           The permissible ciphersuites for encrypted connections that use
184           TLSv1.3. The value is a list of one or more colon-separated
185           ciphersuite names. The ciphersuites that can be named for this
186           option depend on the SSL library used to compile MySQL. For
187           details, see Section 6.3.2, “Encrypted Connection TLS Protocols and
188           Ciphers”.
189
190           This option was added in MySQL 8.0.16.
191
192       ·   --tls-version=protocol_list
193
194           The permissible TLS protocols for encrypted connections. The value
195           is a list of one or more comma-separated protocol names. The
196           protocols that can be named for this option depend on the SSL
197           library used to compile MySQL. For details, see Section 6.3.2,
198           “Encrypted Connection TLS Protocols and Ciphers”.
199
200       ·   --use-default
201
202           Execute noninteractively. This option can be used for unattended
203           installation operations.
204
205       ·   --user=user_name, -u user_name
206
207           The user name of the MySQL account to use for connecting to the
208           server.
