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\ \&6.2.2.2, \(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 mysql .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 mysql \-\-login\-path=mypath .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, unless \fB\-\-no\-login\-paths\fR is set\&. 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 is not likely to 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 mysql_config_editor [\fIprogram_options\fR] \fIcommand\fR [\fIcommand_options\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 mysql_config_editor \-\-help set mysql_config_editor set \-\-help .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 $> \fBmysql_config_editor set \-\-login\-path=client \-\-host=localhost \-\-user=localuser \-\-password\fR Enter password: \fIenter password "localpass" here\fR $> \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 $> \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 mysql \-\-login\-path=remote .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 mysql \-\-login\-path=client .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 mysql .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 mysql \-\-login\-path=remote \-\-host=remote2\&.example\&.com .fi .if n \{\ .RE .\} .sp mysql_config_editor General Options .PP \fBmysql_config_editor\fR supports the following general options, which may be used preceding any command named on the command line\&. For descriptions of command\-specific options, see mysql_config_editor Commands and Command-Specific Options\&. .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fB\-\-help\fR, \fB\-?\fR .TS allbox tab(:); lB l.

For descriptions of these options, see mysql_config_editor General Options\&. .PP \fBmysql_config_editor\fR supports these commands: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} help .sp Display a general help message and exit\&. This command takes no following options\&. .sp To see a command\-specific help message, invoke \fBmysql_config_editor\fR as follows, where \fIcommand\fR is a command other than help: .sp .if n \{\ .RS 4 .\} .nf mysql_config_editor \fIcommand\fR \-\-help .fi .if n \{\ .RE .\} .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} print [\fIoptions\fR] .sp Print the contents of the login path file in unobfuscated form, with the exception that passwords are displayed as *****\&. .sp The default login path name is client if no login path is named\&.
