Clone existing server to create new server
mysqlserverclone [options]
This utility permits an administrator to clone an existing MySQL server instance to start a new server instance on the same host. The utility creates a new datadir (--new-data), and starts the server with a socket file. You can optionally add a password for the login user account on the new instance.
If the user does not have read and write access to the folder specified by the --new-data option, the utility shall issue an error.
Similarly, if the folder specified by --new-data exists and is not empty, the utility will not delete the folder and will issue an error message. Users must specify the --delete-data option to permit the utility to remove the folder prior to starting the cloned server.
OPTIONS
mysqlserverclone accepts the following command-line options:
--help
Display a help message and exit.
--delete-data
Delete the folder specified by --new-data if it exists and is not empty.
--mysqld=<options>
Additional options for mysqld. To specify multiple options, separate them by spaces. Use appropriate quoting as necessary. For example, to specify --log-bin=binlog and --general-log-file="mylogfile", use:
--mysqld="--log-bin=binlog --general-log-file='my log file'"
--new-data=<path_to_new_datadir>
The full path name of the location of the data directory for the new server instance. If the directory does not exist, the utility will create it.
--new-id=<server_id>
The server_id value for the new server instance. The default is 2.
--new-port=<port>
The port number for the new server instance. The default is 3307.
--quiet, -q
Turn off all messages for quiet execution.
--root-password=<password>
The password for the root user of the new server instance.
--server=<source>
Connection information for the server to be cloned in <user>[:<passwd>]@<host>[:<port>][:<socket>] format.
--start-timeout=<timeout_in_seconds>
Number of seconds to wait for server to start. Default = 10 seconds.
--verbose, -v
Specify how much information to display. Use this option multiple times to increase the amount of information. For example, -v = verbose, -vv = more verbose, -vvv = debug.
--version
Display version information and exit.
--write-command=<file_name>, -w<file_name>
Path name of file in which to write the command used to launch the new server instance.
EXAMPLES
The following command demonstrates how to create a new instance of a running server, set the root user password and enable binary logging:
$ mkdir /source/test123 $ mysqlserverclone --server=root:pass@localhost \ --new-data=/Users/cbell/source/test123 --new-port=3310 \ --root-password=pass --mysqld=--log-bin=mysql-bin # Cloning the MySQL server running on localhost. # Creating new data directory... # Configuring new instance... # Locating mysql tools... # Setting up empty database and mysql tables... # Starting new instance of the server... # Testing connection to new instance... # Success! # Setting the root password... # ...done.
