DrizzleÃ‚Â is an open source fork of MySQL, actually InnoDB only, that is designed to be faster and more scalable than the vanilla MySQL.
I finally decided to test it out instead of just mucking around as I had done earlier. * My system *
uname -a Linux Tron 3.0.0-13-generic #22-Ubuntu SMP Wed Nov 2 13:25:36 UTC 2011 i686 i686 i386 GNU/Linux</pre>
Headed over toÃ‚Â DrizzleÃ‚Â and proceeded to see how I can install their box version. I chose Ubuntu as I have a bare metal 11.10 which will do quite well to test both MySQL and Drizzle out. Followed instructions athttp://docs.drizzle.org/installing/ubuntu.htmlÃ‚Â The CentOS install looks a lot lengthier (workarounds?). The best way would be to compile from source but I am not really interested in that right now.
At the update I get the following errors. This is understandable.

They have been ignored, or old ones used instead.</pre>
However, I was able to complete installation without issues. Time to RTFM. Yes! I like to dive first read later, makes it more interesting.
If you visit the docsÃ‚Â http://docs.drizzle.org/configuration/options.html#config-filesÃ‚Â you will see it does not really say where the config file is. This tells me that Drizzle assumes prior knowledge of MySQL Administration so you can fill in the gaps yourself, but Drizzle is very different. Or you could help with Documentation yeah? Drizzle claims to work without configuration out-of-the-box. However since I do have a mysql protocol port used I want to make sure I override it in Drizzle.
I create my config directories under a regular user, in mysql it just went to /etc/ mount point by default. Drizzle made no assumption, there was no directory or anything. Maybe it’s just on Ubuntu, honestly I don’t know. Doc says default direcroty is /etc/drizzle. it even goes on to say that it has a specific name for the default file if you want to skip specifying one.
cd ~ mkdir drizzled touch drizzled/drizzled.cnf # touch drizzled/conf.d/server1.cnf # drizzle will read all configs in this directory automatically touch drizzled/conf.d/auth touch drizzled/users</pre>
This is good enough for me. So I can now specify a default conf and a directory with all my config in case I need more than one.
adding the config values I need.
drizzle-protocol.port=4427 mysql-protocol.port=3307 # since I use 3306 for mysql innodb.buffer-pool-size=500M
Edit the auth file , which you should set to strict permission I suppose. In drizzled/conf.d/auth where I will write what the doc says.
plugin-remove=auth_all plugin-add=auth_file # Options for the plugin itself [auth-file] users=/home/drizzle/drizzled/users #assuming your home is drizzle a full path is needed.
I could apparently write everything in one file (drizzled.cnf) except the users.
The documentation breaks off at this point and goes into details of Options and Values so I go looking for RTFM on Auth.
Setup of authentication
This I like, you can easily setup Auth just like PostGreSQL anyway you want. You can read more hereÃ‚Â http://docs.drizzle.org/administration/authentication.htmlÃ‚Â To keep things simple I used flat file. The suggested way is Schema which is same as MySQL, meaning usernames and passwords are stored in a table inside the database of the Drizzle DB, like theÃ‚Â
userÃ‚Â table. To set that up will take more time but the gyst is, we first allow all, then create an admin users…snore. Feel free to read about it and knowck yourself out. Moving on to Flat file …
Since I already added my flat file settings above I am going to now fill it in with my users. This is easy (or so I thought), e.g.
I suppose we’re done here, it was painful but now I have a neat gun. Now the good stuff.
Start your engine
drizzled –config-dir=/home/drizzle/drizzled/ Ã‚Â output:Ã‚Â Local catalog /var/lib/drizzle/local does not exist
Ã‚Â wtf! ouch!
Troubleshooting…as its obviously a permission issue.
Seems I am logged in as userÃ‚Â abhishekÃ‚Â but drizze is userÃ‚Â drizzleÃ‚Â facepalmÃ‚Â A handy command line option appears: [-u] Unfortunately I need to sudo and then provide the user. Directly won;t workÃ‚Â
Ã‚Â To daemonize it, we need spawns @[email protected]
#sudo drizzled –user drizzle –config-dir=/home/drizzle/drizzled/
sudo drizzled –user drizzle –daemon –config-dir=/home/drizzle/drizzled/
_ I believe my setup is wrong on this part, it could have been done better. It works fine for now so I can test _ We’re online, lets login.
wtf!, I can login. So it seems my default file is not being read, contrary to RTFM. fair enough. I forced the –defaults-file= option but I got a new error. It turns out I need the plugin forÃ‚Â auth-fileÃ‚Â which I am trying to use. I don’t know where I can download this, docs are being generally unhelpful here. Time to go fish… a.k.a google.
I never did get the auth working. I stopped using drizzle, though i believe you can use it as embedded DB or something.
