--angel-pid-file=file_name

The file in which the angel process records its process ID when mysqlmanager runs in daemon mode (that is, when the --run-as-service option is given). The default file name is mysqlmanager.angel.pid.

If the --angel-pid-file option is not given, the default angel PID file has the same name as the PID file except that any PID file extension is replaced with an extension of .angel.pid. (For example, mysqlmanager.pid becomes mysqlmanager.angel.pid.)

This option was added in MySQL 5.0.23.

--bind-address=IP

The IP address to bind to.

--default-mysqld-path=path

The path name of the MySQL Server binary. This path name is used for all server instance sections in the configuration file for which no mysqld-path option is present. The default value of this option is the compiled-in path name, which depends on how the MySQL distribution was configured. Example: --default-mysqld-path=/usr/sbin/mysqld

--defaults-file=file_name

Read Instance Manager and MySQL Server settings from the given file. All configuration changes made by the Instance Manager will be written to this file. This must be the first option on the command line if it is used, and the file must exist.

If this option is not given, Instance Manager uses its standard configuration file. On Windows, the standard file is my.ini in the directory where Instance Manager is installed. On Unix, the standard file is /etc/my.cnf.

--install

On Windows, install Instance Manager as a Windows service. The service name is MySQL Manager. This option was added in MySQL 5.0.11.

--log=file_name

The path to the Instance Manager log file. This option has no effect unless the --run-as-service option is also given. If the file name specified for the option is a relative name, the log file is created under the directory from which Instance Manager is started. To ensure that the file is created in a specific directory, specify it as a full path name.

If --run-as-service is given without --log, the log file is mysqlmanager.log in the data directory.

If --run-as-service is not given, log messages go to the standard output. To capture log output, you can redirect Instance Manager output to a file:

mysqlmanager > im.log

--monitoring-interval=seconds

The interval in seconds for monitoring server instances. The default value is 20 seconds. Instance Manager tries to connect to each monitored (guarded) instance using the nonexisting MySQL_Instance_Manager user account to check whether it is alive/not hanging. If the result of the connection attempt indicates that the instance is unavailable, Instance Manager performs several attempts to restart the instance.

Normally, the MySQL_Instance_Manager account does not exist, so the connection attempts by Instance Manager cause the monitored instance to produce messages in its general query log similar to the following:

Access denied for user 'MySQL_Instance_M'@'localhost' (using password: YES)

The nonguarded option in the appropriate server instance section disables monitoring for a particular instance. If the instance dies after being started, Instance Manager will not restart it. Instance Manager tries to connect to a nonguarded instance only when you request the instance's status (for example, with the SHOW INSTANCES status.

See Section 4.6.10.5, “MySQL Server Instance Status Monitoring”, for more information.

--passwd, -P

Prepare an entry for the password file, print it to the standard output, and exit. You can redirect the output from Instance Manager to a file to save the entry in the file. See also Section 4.6.10.4, “Instance Manager User and Password Management”. This

--password-file=file_name

The name of the file where the Instance Manager looks for users and passwords. On Windows, the default is mysqlmanager.passwd in the directory where Instance Manager is installed. On Unix, the default file is /etc/mysqlmanager.passwd. See also Section 4.6.10.4, “Instance Manager User and Password Management”.

--pid-file=file_name

The process ID file to use. On Windows, the default file is mysqlmanager.pid in the directory where Instance Manager is installed. On Unix, the default is mysqlmanager.pid in the data directory.

--port=port_num

The port number to use when listening for TCP/IP connections from clients. The default port number (assigned by IANA) is 2273.

--print-defaults

Print the current defaults and exit. This must be the first option on the command line if it is used.

--remove

On Windows, removes Instance Manager as a Windows service. This assumes that Instance Manager has been run with --install previously. This option was added in MySQL 5.0.11.

--run-as-service

On Unix, daemonize and start an angel process. The angel process monitors Instance Manager and restarts it if it crashes. (The angel process itself is simple and unlikely to crash.)

--socket=path

On Unix, the socket file to use for incoming connections. The default file is named /tmp/mysqlmanager.sock. This option has no meaning on Windows.

--standalone

This option is used on Windows to run Instance Manager in standalone mode. You should specify it when you start Instance Manager from the command line. This option was added in MySQL 5.0.13.

--user=user_name

On Unix, the user name of the system account to use for starting and running mysqlmanager. This option generates a warning and has no effect unless you start mysqlmanager as root (so that it can change its effective user ID), or as the named user. It is recommended that you configure mysqlmanager to run using the same account used to run the mysqld server. (“User” in this context refers to a system login account, not a MySQL user listed in the grant tables.)

--version, -V

Display version information and exit.

--wait-timeout=N

The number of seconds to wait for activity on an incoming connection before closing it. The default is 28800 seconds (8 hours).

This option was added in MySQL 5.0.19. Before that, the timeout is 30 seconds and cannot be changed.
