I can tell. Its written in "proper" english. :)

hi ruaok!

I dont think I really understood your last email to me. try me again, please?

basically when we shutdown all our webservice apps (apprx 5-6) on multiple hosts....response is fine now with single user test..

ah, I see.

we need to check some configs then to see where the bottle neck might be.

ah!

so i recall warp or someone mentioned on Friday chat..that MB server looks for it's clients that requests came from..

yes

and we've our webservice on top that connects to this mb server..

did you ever change the web server inside the VM?

because right now its using a dev server setup.

but since we're now actually deploying this, you ought to install nginx inside the VM and deploy the mb-server app inside that.

I think I may switch to this method for an upcoming release of the VM.

or at least allow both to be done easily.

change webserver? didn't get that..like what?

so, the VM comes setup with a catalyst based development server.

that isn't meant to handle more than 1-2 clients connecting to it.

ha ok..

so, we need to deploy a better web server inside the Vm that has more throughput.

no we didn't change on that side..only thing we changed was point to our own external postgres mb db host, and search server

have you ever used nginx?

ah, ok.

yeah, we need to tweak that then.

no ..but i can try..

all the hard stuff is done for you, since we deploy to nginx

log into the VM

then

apt-get install nginx

k

ping me when that's done so we can configure the server.

i guess i need to be root ..right?

yep

sudo su -

password is musicbrainz, unless you folks changed that

done

cd /etc/nginx

hmmm.

all the config files are in ~musicbrainz/admin/nginx

so we're going to link to those files with symlinks.

gimme a sec while I fire up an instance.

ok

More spam from http://gccalliance.org/ in the wiki

moin ruaok !

moin ocharles

ruaok: "proper" english? does that mean I write in such a british way or that reosarevok can't speak english? :P

nikki: a little of both. :)

reosarevok, you'll probably just get sucked into a cult if you do that. :P

:p

awww, sorry reosarevok

Leftmost, I can't, I'm already in the MB cult :p

Where we worship consistent data.

ruaok: funnily enough, someone requested something pretty similar to what we were talking about on Style yesterday :p

(completely independently)

Swarup: lets continue.

k

cd /etc/nginx/sites-available

done

ln -s ~musicbrainz/musicbrainz-server/admin/nginx/001-musicbrainz .

cd ../sites-enabled/

rm default

ln -s ../sites-available/001-musicbrainz .

ocharles: can you have another look at http://codereview.musicbrainz.org/r/1570/ ? I'd like to get that in master.

warp: okie doke

ruaok..done

Swarup:

cd ..

mv nginx.conf nginx.conf.default

done

that may be all we need to do, but I need to double check that. hold on

ln -s ~musicbrainz/musicbrainz-server/admin/nginx/mbserver-rewrites.conf .

uh oh.

Mmm?

the posse slowly rolls in.

hi zacd! :)

Took me a while to run an extension cord outside the fence. Port 6667 is blocked on the office net.

lol

Swarup:

/etc/init.d/nginx stop

/etc/init.d/nginx start

zacd: freenode has a web irc client that just uses port 80.

ah, before you do that, stop the dev server, Swarup

ok

might be ok, since dev server runs on a different port, but still.

now if you go to the servers address you should get a 502 bad gateway error.

got this..probably some setup issue..

../etc/init.d/nginx start Starting nginx: [emerg]: open() "/etc/nginx/nginx.conf" failed (2: No such file or directory) configuration file /etc/nginx/nginx.conf test failed

What're you guys trying to do, exactly?

setting up nginx on mb vm ..to handle throughput..

Swarup: ls /etc/nginx

But like...

you should have a symlink from nginx.conf going to /home/musicbrainz/musicbrainz-server/admin/nginx/nginx.conf

We're not running out of host resources from what I can tell...

ls /etc/nginx conf.d fastcgi_params koi-utf koi-win mbserver-rewrites.conf mime.types nginx.conf.default scgi_params sites-available sites-enabled uwsgi_params win-utf

What are we running out of?

zacd: the server that ships with the VM is a dev server not setup for a great amount of throughput.

not sure of the exact thing we're running out of, but we were doing it wrong for this case.

so we're setting up nginx, to do it right.

then we can check to see the throughput. that should improve things a lot.

Swarup: cd /etc/nginx

ln -s ~musicbrainz/musicbrainz-server/admin/nginx/nginx.conf .

y on it

then try the start again

k

../etc/init.d/nginx start Starting nginx: [emerg]: open() "/etc/nginx/site-name.conf" failed (2: No such file or directory) in /etc/nginx/sites-enabled/001-musicbrainz:3 configuration file /etc/nginx/nginx.conf test failed

ah, I think my vm is a bit behind the times.

should i add same sym link for it too..

that file isn't in git.

one sec.

warp: ship ship ship

ocharles: yay!

Swarup: create the file and have it contain only one line:

server_name musicbrainz.org;

k

thats for our server. put whatever valid DNS name you intent to use in there.

then restart

(nginx that is)

../etc/init.d/nginx start Starting nginx: [warn]: duplicate MIME type "text/html" in /etc/nginx/sites-enabled/001-musicbrainz:16 [warn]: duplicate MIME type "text/html" in /etc/nginx/sites-enabled/001-musicbrainz:29 nginx.

warnings..is that ok..

yeah. I'll leave that to you to clean up. ;)

k

ok, we're half done.

apt-get install daemontools daemontools-run

done

cd /usr/local

mkdir musicbrainz-server

cd musicbrainz-server/

k

done

cp ~musicbrainz/musicbrainz-server/admin/nginx/service/run .

edit run

look for nproc

its set to 5

that is the number of processes to start

how much ram does the VM have?

done..command to check ram..let me see..

free

total used free shared buffers cached Mem: 1024968 617204 407764 0 105868 426012 -/+ buffers/cache: 85324 939644 Swap: 1044476 3800 1040676

that will also be a problem for you guys.
