MYSQLSERVERCLONE(1)

NAME
mysqlserverclone - Clone Existing Server to Create New Server

SYNOPSIS

mysqlserverclone [options]

DESCRIPTION

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
