Laziness
Laziness is a disinclination to
activity or exertion despite
having the ability to do so.

http://en.wikipedia.org/wiki/Laziness

I have the ability

• but I don't feel inclined to do repetitive
work
• I ADMIT IT: I AM LAZY


A lazy developer ®

Someone who writes 12,000
lines of code to spare himself (*)
the trouble of typing 15 lines
on a terminal.
(*) And another 1,000,000 people

MySQL Sandbox
http://mysqlsandbox.net
• Free software (Perl under GPL)
• One (unix) host
• Many database servers
• Single or multiple sandboxes
• Customized scripts to use the servers
• Standard or circular replication
• Supports MySQL, Percona, MariaDB servers
• Installs IN SECONDS

$ make_sandbox

# it should work always

$ make_sandbox 5.1.54

Where do you get it

•from CPAN
$ sudo su -
# cpan MySQL::Sandbox

•from launchpad
http://launchpad.net/mysql-sandbox

# or, after some preparation

$ make_replication_sandbox 5.1.54

creating a single sandbox
make_sandbox
/path/to/mysql-X.X.XX-OS.tar.gz


using a single sandbox
# after
# make_sandbox
# /path/to/mysql-X.X.XX-OS.tar.gz

$ cd $SANDBOX_HOME/msb_X_X_XX
$ ./use


creating a single sandbox
with a speciﬁc options ﬁle

make_sandbox
/path/to/mysql-X.X.XX-OS.tar.gz
-- --my_file=/path/to/my.cnf


easily create a sandbox after the ﬁrst
one
The long way
$ cd $HOME/opt/mysql # $SANDBOX_BINARY
$ gunzip -c
/path/to/mysql-5.1.34-osx10.5-x86.tar.gz
| tar -xf -
$ mv mysql-5.1.34-osx10.5-x86 5.1.34
$ make sandbox 5.1.34


easily create a sandbox after the ﬁrst
one
The short way
$ make_sandbox --export_binaries
path/to/mysql-5.1.34-osx10.5-x86.tar.gz


starting a single sandbox
$ ./start


starting a single sandbox
with temporary options
$ ./start --option=value

$ ./restart --option=value

$ ./start --key-buffer=20000000


creating a sandbox with custom port
and directory
$ make_sandbox 5.1.34 --
--sandbox_port=7800
--sandbox_directory=mickeymouse


creating a sandbox with automatic
port checking
$ make_sandbox 5.1.34 -- --check_port

# if 5.1.34 is free
# port=5134
# directory=msb_5_1_34
# else
# port=5135 (or the first free)
# directory=msb_5_1_34_a


create a replication sandbox

$ make_replication_sandbox
path/to/mysql-5.1.34-osx10.5-x86.tar.gz


changing port to an existing sandbox

$ sbtool -o port
-s /path/to/source/sandbox
--new_port=XXXX


more recipes

$ perldoc MySQL::Sandbox::Recipes


MySQL Sandbox evolution


More ﬂexible

• make_sandbox
• --high_performance
• --master (creates a standalone master)
• --slaveof (makes a quick slave of an
existing server, even of different versions)


create a customized replication
system

$ make_sandbox 5.1.57 -- --master

-- --slaveof='master_port=5157'

-- --slaveof='master_port=5157'


Easier to integrate in other
systems
• make_multiple_sandbox,
make_replication_sandbox
• --node_options='options'
• --one_slave_option='N:options'
• --one_node_option='N:options'
• --master_options='options'
• --slave_options='options'
