mysql_config_editor \- configure authentication information for connecting to MySQL server
.SH "SYNOPSIS"
.HP \w'\fBmysql_config_editor\ \fR\fB\fIoptions\ command\fR\fR\ 'u
\fBmysql_config_editor \fR\fB\fIoptions command\fR\fR
.SH "DESCRIPTION"
.PP
The
\fBmysql_config_editor\fR
utility enables you to store authentication credentials in an obfuscated login path file named
\&.mylogin\&.cnf\&. The file location is the
%APPDATA%\eMySQL
directory on Windows and the current user\*(Aqs home directory on non\-Windows systems\&. The file can be read later by MySQL client programs to obtain authentication credentials for connecting to MySQL Server\&.
.PP
The unobfuscated format of the
\&.mylogin\&.cnf
login path file consists of option groups, similar to other option files\&. Each option group in
\&.mylogin\&.cnf
is called a
\(lqlogin path,\(rq
which is a group that permits only certain options:
\fBhost\fR,
\fBuser\fR,
\fBpassword\fR,
\fBport\fR
and
\fBsocket\fR\&. Think of a login path option group as a set of options that specify which MySQL server to connect to and which account to authenticate as\&. Here is an unobfuscated example:
.sp
.if n \{\
.RS 4
.\}
.nf
[client]
user = mydefaultname
password = mydefaultpass
host = 127\&.0\&.0\&.1
[mypath]
user = myothername
password = myotherpass
host = localhost
.fi
.if n \{\
.RE
.\}
.PP
When you invoke a client program to connect to the server, the client uses
\&.mylogin\&.cnf
in conjunction with other option files\&. Its precedence is higher than other option files, but less than options specified explicitly on the client command line\&. For information about the order in which option files are used, see
Section\ \&4.2.6, \(lqUsing Option Files\(rq\&.
.PP
To specify an alternate login path file name, set the
MYSQL_TEST_LOGIN_FILE
environment variable\&. This variable is recognized by
\fBmysql_config_editor\fR, by standard MySQL clients (\fBmysql\fR,
\fBmysqladmin\fR, and so forth), and by the
\fBmysql\-test\-run\&.pl\fR
testing utility\&.
.PP
Programs use groups in the login path file as follows:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBmysql_config_editor\fR
operates on the
client
login path by default if you specify no
\fB\-\-login\-path=\fR\fB\fIname\fR\fR
option to indicate explicitly which login path to use\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
Without a
\fB\-\-login\-path\fR
option, client programs read the same option groups from the login path file that they read from other option files\&. Consider this command:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql\fR
.fi
.if n \{\
.RE
.\}
.sp
By default, the
\fBmysql\fR
client reads the
[client]
and
[mysql]
groups from other option files, so it reads them from the login path file as well\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
With a
\fB\-\-login\-path\fR
option, client programs additionally read the named login path from the login path file\&. The option groups read from other option files remain the same\&. Consider this command:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql \-\-login\-path=mypath\fR
.fi
.if n \{\
.RE
.\}
.sp
The
\fBmysql\fR
client reads
[client]
and
[mysql]
from other option files, and
[client],
[mysql], and
[mypath]
from the login path file\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
Client programs read the login path file even when the
\fB\-\-no\-defaults\fR
option is used\&. This permits passwords to be specified in a safer way than on the command line even if
\fB\-\-no\-defaults\fR
is present\&.
.RE
.PP
\fBmysql_config_editor\fR
obfuscates the
\&.mylogin\&.cnf
file so it cannot be read as cleartext, and its contents when unobfuscated by client programs are used only in memory\&. In this way, passwords can be stored in a file in non\-cleartext format and used later without ever needing to be exposed on the command line or in an environment variable\&.
\fBmysql_config_editor\fR
provides a
print
command for displaying the login path file contents, but even in this case, password values are masked so as never to appear in a way that other users can see them\&.
.PP
The obfuscation used by
\fBmysql_config_editor\fR
prevents passwords from appearing in
\&.mylogin\&.cnf
as cleartext and provides a measure of security by preventing inadvertent password exposure\&. For example, if you display a regular unobfuscated
my\&.cnf
option file on the screen, any passwords it contains are visible for anyone to see\&. With
\&.mylogin\&.cnf, that is not true\&. But the obfuscation used will not deter a determined attacker and you should not consider it unbreakable\&. A user who can gain system administration privileges on your machine to access your files could unobfuscate the
\&.mylogin\&.cnf
file with some effort\&.
.PP
The login path file must be readable and writable to the current user, and inaccessible to other users\&. Otherwise,
\fBmysql_config_editor\fR
ignores it, and client programs do not use it, either\&.
.PP
Invoke
\fBmysql_config_editor\fR
like this:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql_config_editor [\fR\fB\fIprogram_options\fR\fR\fB] \fR\fB\fIcommand\fR\fR\fB [\fR\fB\fIcommand_options\fR\fR\fB]\fR
.fi
.if n \{\
.RE
.\}
.PP
If the login path file does not exist,
\fBmysql_config_editor\fR
creates it\&.
.PP
Command arguments are given as follows:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fIprogram_options\fR
consists of general
\fBmysql_config_editor\fR
options\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
command
indicates what action to perform on the
\&.mylogin\&.cnf
login path file\&. For example,
set
writes a login path to the file,
remove
removes a login path, and
print
displays login path contents\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fIcommand_options\fR
indicates any additional options specific to the command, such as the login path name and the values to use in the login path\&.
.RE
.PP
The position of the command name within the set of program arguments is significant\&. For example, these command lines have the same arguments, but produce different results:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql_config_editor \-\-help set\fR
shell> \fBmysql_config_editor set \-\-help\fR
.fi
.if n \{\
.RE
.\}
.PP
The first command line displays a general
\fBmysql_config_editor\fR
help message, and ignores the
set
command\&. The second command line displays a help message specific to the
set
command\&.
.PP
Suppose that you want to establish a
client
login path that defines your default connection parameters, and an additional login path named
remote
for connecting to the MySQL server the host
remote\&.example\&.com\&. You want to log in as follows:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
By default, to the local server with a user name and password of
localuser
and
localpass
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
To the remote server with a user name and password of
remoteuser
and
remotepass
.RE
.PP
To set up the login paths in the
\&.mylogin\&.cnf
file, use the following
set
commands\&. Enter each command on a single line, and enter the appropriate passwords when prompted:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql_config_editor set \-\-login\-path=client
         \-\-host=localhost \-\-user=localuser \-\-password\fR
Enter password: \fIenter password "localpass" here\fR
shell> \fBmysql_config_editor set \-\-login\-path=remote
         \-\-host=remote\&.example\&.com \-\-user=remoteuser \-\-password\fR
Enter password: \fIenter password "remotepass" here\fR
.fi
.if n \{\
.RE
.\}
.PP
\fBmysql_config_editor\fR
uses the
client
login path by default, so the
\fB\-\-login\-path=client\fR
option can be omitted from the first command without changing its effect\&.
.PP
To see what
\fBmysql_config_editor\fR
writes to the
\&.mylogin\&.cnf
file, use the
print
command:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql_config_editor print \-\-all\fR
[client]
user = localuser
password = *****
host = localhost
[remote]
user = remoteuser
password = *****
host = remote\&.example\&.com
.fi
.if n \{\
.RE
.\}
.PP
The
print
command displays each login path as a set of lines beginning with a group header indicating the login path name in square brackets, followed by the option values for the login path\&. Password values are masked and do not appear as cleartext\&.
.PP
If you do not specify
\fB\-\-all\fR
to display all login paths or
\fB\-\-login\-path=\fR\fB\fIname\fR\fR
to display a named login path, the
print
command displays the
client
login path by default, if there is one\&.
.PP
As shown by the preceding example, the login path file can contain multiple login paths\&. In this way,
\fBmysql_config_editor\fR
makes it easy to set up multiple
\(lqpersonalities\(rq
for connecting to different MySQL servers, or for connecting to a given server using different accounts\&. Any of these can be selected by name later using the
\fB\-\-login\-path\fR
option when you invoke a client program\&. For example, to connect to the remote server, use this command:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql \-\-login\-path=remote\fR
.fi
.if n \{\
.RE
.\}
.PP
Here,
\fBmysql\fR
reads the
[client]
and
[mysql]
option groups from other option files, and the
[client],
[mysql], and
[remote]
groups from the login path file\&.
.PP
To connect to the local server, use this command:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql \-\-login\-path=client\fR
.fi
.if n \{\
.RE
.\}
.PP
Because
\fBmysql\fR
reads the
client
and
mysql
login paths by default, the
\fB\-\-login\-path\fR
option does not add anything in this case\&. That command is equivalent to this one:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql\fR
.fi
.if n \{\
.RE
.\}
.PP
Options read from the login path file take precedence over options read from other option files\&. Options read from login path groups appearing later in the login path file take precedence over options read from groups appearing earlier in the file\&.
.PP
\fBmysql_config_editor\fR
adds login paths to the login path file in the order you create them, so you should create more general login paths first and more specific paths later\&. If you need to move a login path within the file, you can remove it, then recreate it to add it to the end\&. For example, a
client
login path is more general because it is read by all client programs, whereas a
mysqldump
login path is read only by
\fBmysqldump\fR\&. Options specified later override options specified earlier, so putting the login paths in the order
client,
mysqldump
enables
\fBmysqldump\fR\-specific options to override
client
options\&.
.PP
When you use the
set
command with
\fBmysql_config_editor\fR
to create a login path, you need not specify all possible option values (host name, user name, password, port, socket)\&. Only those values given are written to the path\&. Any missing values required later can be specified when you invoke a client path to connect to the MySQL server, either in other option files or on the command line\&. Any options specified on the command line override those specified in the login path file or other option files\&. For example, if the credentials in the
remote
login path also apply for the host
remote2\&.example\&.com, connect to the server on that host like this:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql \-\-login\-path=remote \-\-host=remote2\&.example\&.com\fR
.fi
.if n \{\
