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

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

Laziness

I am an experienced DBA• I have the ability of installing

multiple MySQL servers.

• In the same host.

• Without conflicting.

• Manually.

• Do I feel inclined to do so?

• Several times a day?

• I DON'T THINK SO.

I am a command line wizard

• After installing multiple servers

• I can use them

• with various long options.

• Manually.

• Many dozen times a day?

• I DEFINITELY DON'T THINK SO.

I can set up replication

• Almost without errors.

• And then I can connect to masters and slaves with long options on the command line.

I can set up circular replication

• Almost always with errors.

• And cursing.

I can install plugins

• After reading the manual.

• And translating from intentions to reality.

• And copying-and-pasting.

I have the ability

• but I don't feel inclined to do repetitive work

• I ADMIT IT: I AM LAZY

YES: I AM A LAZY

DEVELOPER

A lazy developer ®

Someone who writes 12,000 lines of code to save himself the trouble of typing 15 lines on a terminal.

(*) And another 1,000,000 people

That's me

And after this presentation,

you will feel lazy too

•One (unix) host

•Many database servers

•Single or multiple sandboxes

•Customized scripts to use the servers

•Standard or circular replication

•Installs IN SECONDS

creating a single sanboxmake_sandbox \ /path/to/mysql-X.X.XX-OS.tar.gz

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

$ cd $SANDBOX_HOME/msb_X_X_XX$ ./use

creating a single sanboxwith 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 \ path/to/mysql-5.1.34-osx10.5-x86.tar.gz \ --export_binaries

The short way

starting a single sanbox$ cd $SANDBOX_HOME/msb_X_X_XX$ ./start

starting a single sanboxwith 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

create a circular replication sandbox

$ make_replication_sandbox \ --circular=4 \ 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

installing the innodb plugin

$ sbtool -o plugin \ --plugin=innodb \ -s /path/to/source/sandbox

creating a replication sandbox with new base port

$ make_replication_sandbox \ --replication_directory=newwdir \ --check_base_port 5.0.79

# Creates a replication directory under# $SANDBOX_HOME/newdir# The previous one is preserved. # No conflicts happen

roadmap: what's up

• new architecture:

• one deployer class (can install a server)

• subclasses will deploy on different O.S.

• setup wizard for test and production

• Cluster friendly

• Cloud friendly
