mysqlserverclone \- Clone Existing Server to Create New Server
.SH "SYNOPSIS"
.HP \w'\fBmysqlserverclone\ [\fR\fB\fIoptions\fR\fR\fB]\fR\ 'u
\fBmysqlserverclone [\fR\fB\fIoptions\fR\fR\fB]\fR
.SH "DESCRIPTION"
.PP
This utility enables you to clone an existing MySQL server instance to create a new server instance on the same host\&. The utility creates a new datadir (\fB\-\-new\-data\fR), and, on Unix systems, starts the server with a socket file\&. You can optionally add a password for the login user account on the new instance\&.
.PP
If the user does not have read and write access to the folder specified by the
\fB\-\-new\-data\fR
option, the utility will issue an error\&.
.PP
Similarly, if the folder specified by
\fB \-\-new\-data\fR
exists and is not empty, the utility will not delete the folder and will issue an error message\&. Users must specify the
\fB\-\-delete\-data\fR
option to permit the utility to remove the folder prior to starting the cloned server\&.
.PP
The utility does not copy any data\&. It merely creates a new running instance of the cloned server with the same options (or additional options if specified)\&. Thus, to create a copy of a server, you must copy the data after the server is cloned\&.

.sp
If the option \-\-skip\-innodb is included when connecting to a MySQL server version 5\&.7\&.5 or higher, the option is ignored and a warning is issued\&.

Connection information for the server to be cloned\&.
.sp
To connect to a server, it is necessary to specify connection parameters such as the user name, host name, password, and either a port or socket\&. MySQL Utilities provides a number of ways to supply this information\&. All of the methods require specifying your choice via a command\-line option such as \-\-server, \-\-master, \-\-slave, etc\&. The methods include the following in order of most secure to least secure\&.

.sp
.if n \{\

.nf
shell> \fBmkdir /source/test123\fR
shell> \fBmysqlserverclone \-\-server=root:pass@localhost \e\fR

# 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\&.

.if n \{\
.RE
.\}
.sp
PERMISSIONS REQUIRED.PP
The user must have permission to read all databases\&. Since we are using the root account for these examples (and you typically would), permissions are not generally a problem\&.
.PP
You also need permissions to create the new data directory and write data to it\&.
