The port number to use when listening for TCP/IP connections. On Unix and Unix-like systems, the port number must be 1024 or higher unless the server is started by the root  operating system user. Setting this option to 0 causes the default value to be used. 

• --port-open-timeout= num

On some systems, when the server is stopped, the TCP/IP port might not become available immediately. If the server is restarted quickly afterward, its attempt to reopen the port can fail. This option indicates how many seconds the server should wait for the TCP/IP port to become free if it cannot be opened. The default is not to wait. 

• --print-defaults 

Print the program name and all options that it gets from option files. Password values are masked. This must be the first option on the command line if it is used, except that it may be used immediately after -- defaults-file  or --defaults-extra-file . 

For additional information about this and other option-file options, see Section 4.2.2.3, “Command-Line Options that Affect Option-File Handling” . 

• --remove [ service_name ]

(Windows only) Remove a MySQL Windows service. The default service name is MySQL  if no service_name  value is given. For more information, see Section 2.3.4.8, “Starting MySQL as a Windows Service” . 

• --safe-user-create

If this option is enabled, a user cannot create new MySQL users by using the GRANT  statement unless the user has the INSERT  privilege for the mysql.user  system table or any column in the table. If you want a user to have the ability to create new users that have those privileges that the user has the right to grant, you should grant the user the following privilege: 

GRANT INSERT(user) ON mysql.user TO ’ user_name ’@’ host_name ’; 

This ensures that the user cannot change any privilege columns directly, but has to use the GRANT statement to give privileges to other users. 

• --skip-grant-tables
