1.7-Alpha sneek peek - Airtime Support Discussions on Sourcefabric Forum

Ed Boon

Hi there Airtime guru's,

i did a quick install of 1.7-alpha in my test-environment, that is a virtual debian machine on my laptop. I noted a number of things:
1) i got the login screen on my test url, but i cannot login. Any suggestions? installation seems to be ok, because
2) i found the pypo-liquidsoap log. it seems there's a lot of changes, like logging (no pypo-fetch and pypo-push logs?)
3) what made the change from 1.6.1 to 1.7-alpha really notable, was the level of noise Smile

. The fan of my laptop started blowing like a maniac, because there was a visible increase in CPU usage. Do you have an explanation for that?

thanks already.

best regards
Ed

Ed Boon

Hmm, the install of 1.7-alpha didn't go as smooth as i initially thought. I do see the login screen, but on the tab it says: DB Error: no such table. I did an uninstall and a re-install.
Here's the output of the install:

Hi Ed,
The installation has to be run from the install directory and not from an outside directory.
Can you please do

cd install
sudo php airtime-install.php

The log for pypo-fetch and pypo-push have been merged into pypo.

You can find the location of the log at

/etc/service/pypo/log/main/current

We have begun testing to see if the liquidsoap bundled with Airtime 1.7.0 really does use more CPU. Will get back to you on this.

Martin Konecny

Ed,

We've checked 1.6.1 vs. 1.7.0 in terms of CPU usage for liquidsoap, and they are very similar (around 7% on my machine). Could you post what percentages are being used for you in both Airtime versions. (You can use the "top" command in the terminal for this).

Ed Boon

Thanks, that helped. I should have tried that myself Very Happy

installing from inside the install directory gave me access to the menu.

Ed Boon

Hi,

i got 1.7-alpha to work. The cpu does seem to be slightly increases, but certainly not dramatically. I didn't properly measure the difference, but it is comparable to 1.6.1.
I do get an error in the pypo log:

I cannot seem to figure out where he socket error comes from. Any ideas?

Ed,

Have you looked at the new install page for Airtime 1.7.0?

http://wiki.sourcefabric.org/display/CC/Installing+Airtime+D ev+Version+%28v1.7alpha%29

There are some new packages that are required for install.

Ed Boon

Hi,

in addition to what i wrote before i can see an error at the top of my firefox window when i submit changes to the preferences:
Warning: fsockopen(): unable to connect to 127.0.0.1:5672 (Connection refused) in /var/www/clients/client1/web2/web/airtime/library/php-amqpli b/amqp.inc on line 376

when i tested mp3's to stream the 'on air' sign was not lit and the stream was silent. It could be because of the socket error?

Anyway, thanks for thinking with me.

Yes i did. the additional packages are present. For debian the zend framework packages are called zendframework and zendframework-bin btw.

Thanks,

It looks like rabbitmq is not installed on your machine?

Hmmm, i just checked:

rabbitmq-server is already the newest version.

Ed Boon

Hmm, i just saw the propel-error.log:

BUILD FAILED
/var/www/clients/client1/web2/web/airtime/library/propel/gen erator/build.xml:75:15: No project directory specified.

what's that?

Ed

Ed Boon

OK. I'm getting closer. Another close look at rabbitmq did the following. Although it was installed, an additional command was necessary: apt-get dist-upgrade
Then i rebooted again (just to be sure).

This solved the socket.error: [Errno 111] Connection refused
Smile

There's more to explore, but i'll post my findings later.

Kind regards
Ed

Debian instructions...

So, to sum up the instructions for Debian:
1) remember the zend packages are called 'zenframework' and 'zenframework-bin'
2) for rabbitmq do the following:

Add the following line to your /etc/apt/sources.list:
deb http://www.rabbitmq.com/debian/ testing main

(testing is referring to rabbitmq status)
Optionally add the rabbitmq public key. the commands for this are:
wget http://www.rabbitmq.com/rabbitmq-signing-key-public.asc
sudo apt-key add rabbitmq-signing-key-public.asc

then run:
sudo apt-get update
sudo apt-get install rabbitmq-server

and finally:
sudo apt-get dist-upgrade

For those of you using Debian (squeeze)

Kind regards
Ed

zendframework and zendframework-bin
Very Happy

Zdravko

BTW I had the same error "This solved the socket.error: [Errno 111] Connection refused"

on Ubuntu 10.04. After some research online I've found that I needed to create /etc/rabbitmq/rabbitmq.conf containing only these 2 lines:

NODENAME=rabbit@localhost
NODE_IP_ADDRESS=127.0.0.1

Yesterday this fixed the issue for me with Airtime alpha 1.7.

Unfortunatelly I found that later one it stoped pushing to liquidsoap without any note in any of the logs. So Airtime 1.7 si pushing from time to time to liquidsoap. I hope the playout will be working without issues when we have stable GA release for 1.7

BTW,

Ed I just read you 2nd/3rd post while I'm writing here... I did aptitude search zend -> on my airtime box this is what I got installed so far:

libzend-framework-php

zend-framework-bin

The other 2 you mentioned ( zendframework & zendframework-bin) are available in aptitude but are NOT installed and I'm wondering If I have to use them since there are no error messages anymore in pypo's logs etc.

What do you think?

Verheek

I also added this rabbitmq.conf file but still had the password issue when installing rabbitmq-server on Ubuntu Lucid. It seems to be critical for the /etc/hosts file to be setup correctly or this rabbitmq.conf file to be added for rabbitmq to work.

I had to change the password for the rabbitmq user and the repair the install with apt-get -f install, enter the password and then it worked by itself after that.

I have libzend-framework-php and zend-framework-bin installed.

Jeremy

Ed Boon

Hi,

The zendframework and zendframework-bin packages are the Debian versions and not specifically for Ubuntu. Since you mention you have libzend-framework-php and zend-framework-bin installed, i'd say you don't need them.

With the things i mentioned in my latest posts i got it all to work. No errors to be found and i'm in fact at the moment listening to the first test transmissions with 1.7-alpha.

Good call on the rabbitmq.conf file. Thought I had done that but it must have gotten deleted in one of the install/purge cycles. Now I have

@400000004d962c06226a1cac 2011-04-01 15:48:12,577 INFO - [pypopush.py : run() : line 222] - heartbeat

in my pypo log.
