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

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

I used to install a lot
of MySQL databases
for testing

Then, I decided to
use Perl ...

•One (unix) host
•Many database servers
•Single or multiple sandboxes
•Customized scripts to use the servers
•Standard or circular replication
•Installs IN SECONDS

The easy way - installation

The easy way - single sandbox

$ make_sandbox

# that's it!


The easy way - replication
$ make_replication_sandbox
/path/mysql-OS-5.1.37.tar.gz

# that's it!

creating a single sanbox
make_sandbox

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 sanbox
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
path/to/mysql-5.1.34-osx10.5-x86.tar.gz
--export_binaries


starting a single sanbox
$ ./start


starting a single sanbox
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



create a circular replication
sandbox
--circular=4


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
--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
• written in Python
