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

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.

MySQL Sandbox

• 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

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 sandboxwith 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

$ cd $HOME/opt/mysql$ 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

The long way

# $SANDBOX_BINARY


easily create a sandbox after the first one

$ make_sandbox --export_binaries \ path/to/mysql-5.1.34-osx10.5-x86.tar.gz

The short way


starting a single sandbox

$ cd $SANDBOX_HOME/msb_X_X_XX$ ./start


starting a single sandboxwith temporary options

$ cd $SANDBOX_HOME/msb_X_X_XX$ ./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

$ make_sandbox 5.5.18 \ -- --slaveof='master_port=5157'

$ make_sandbox 5.6.3 \ -- --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'
