If the plugin is not installed, \fBmysql_secure_installation\fR prompts the user whether to install it\&. Any passwords entered later are checked using the plugin if it is enabled\&. .PP Most of the usual MySQL client options such as \fB\-\-host\fR and \fB\-\-port\fR 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: .sp .if n \{\ .RS 4 .\} .nf shell> \fBmysql_secure_installation \-\-host=::1 \-\-port=3307\fR .fi .if n \{\ .RE .\} .PP \fBmysql_secure_installation\fR 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, \(lqUsing Option Files\(rq\&. .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-help\fR, \fB\-?\fR .sp Display a help message and exit\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-defaults\-extra\-file=\fR\fB\fIfile_name\fR\fR .sp 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\&. \fIfile_name\fR is interpreted relative to the current directory if given as a relative path name rather than a full path name\&. .sp For additional information about this and other option\-file options, see Section\ \&4.2.7, \(lqCommand-Line Options that Affect Option-File Handling\(rq\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-defaults\-file=\fR\fB\fIfile_name\fR\fR .sp Use only the given option file\&. If the file does not exist or is otherwise inaccessible, an error occurs\&. \fIfile_name\fR is interpreted relative to the current directory if given as a relative path name rather than a full path name\&. .sp For additional information about this and other option\-file options, see Section\ \&4.2.7, \(lqCommand-Line Options that Affect Option-File Handling\(rq\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-defaults\-group\-suffix=\fR\fB\fIstr\fR\fR .sp Read not only the usual option groups, but also groups with the usual names and a suffix of \fIstr\fR\&. For example, \fBmysql_secure_installation\fR normally reads the [client] and [mysql_secure_installation] groups\&. If the \fB\-\-defaults\-group\-suffix=_other\fR option is given, \fBmysql_secure_installation\fR also reads the [client_other] and [mysql_secure_installation_other] groups\&. .sp For additional information about this and other option\-file options, see Section\ \&4.2.7, \(lqCommand-Line Options that Affect Option-File Handling\(rq\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-host=\fR\fB\fIhost_name\fR\fR, \fB\-h \fR\fB\fIhost_name\fR\fR .sp Connect to the MySQL server on the given host\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-no\-defaults\fR .sp Do not read any option files\&. If program startup fails due to reading unknown options from an option file, \fB\-\-no\-defaults\fR can be used to prevent them from being read\&. .sp 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 \fB\-\-no\-defaults\fR is used\&. (\&.mylogin\&.cnf is created by the \fBmysql_config_editor\fR utility\&. See \fBmysql_config_editor\fR(1)\&.) .sp For additional information about this and other option\-file options, see Section\ \&4.2.7, \(lqCommand-Line Options that Affect Option-File Handling\(rq\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-password=\fR\fB\fIpassword\fR\fR, \fB\-p \fR\fB\fIpassword\fR\fR .sp This option is accepted but ignored\&. Whether or not this option is used, \fBmysql_secure_installation\fR always prompts the user for a password\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-port=\fR\fB\fIport_num\fR\fR, \fB\-P \fR\fB\fIport_num\fR\fR .sp The TCP/IP port number to use for the connection\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-print\-defaults\fR .sp Print the program name and all options that it gets from option files\&. .sp For additional information about this and other option\-file options, see Section\ \&4.2.7, \(lqCommand-Line Options that Affect Option-File Handling\(rq\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-protocol={TCP|SOCKET|PIPE|MEMORY}\fR .sp 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, \(lqConnecting to the MySQL Server\(rq\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-socket=\fR\fB\fIpath\fR\fR, \fB\-S \fR\fB\fIpath\fR\fR .sp For connections to localhost, the Unix socket file to use, or, on Windows, the name of the named pipe to use\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-ssl*\fR .sp Options that begin with \fB\-\-ssl\fR specify whether to connect to the server using SSL and indicate where to find SSL keys and certificates\&.
