Install fails on haproxy about mist-ce HOT 9 CLOSED

Hi, seems that haproxy.org is down indeed (don't know for how long but I would consider letting them know, just in case they are not aware of it).

I can expect it being up very soon, but just in case you'd like to experiment ... here are some steps:

1. git clone mist.io and create a virtualenv and install ansible dependency, according to the installation docs

$git clone https://github.com/mistio/mist.io.git 
$cd mist.io
$virtualenv --no-site-packages .
$./bin/pip install ansible

2. remove haproxy from the buildout section of buildout.cfg (that is removing line 10 at the moment).

3. run bootstrap.py and buildout

$python bootstrap.py && ./bin/buildout -v

4. if this finishes without problems, you have to install haproxy via the system packages (or other way?). For example on Ubuntu/Debian that would be apt-get install haprpoxy -y

Almost there. Create a link to bin/haproxy. On my system this has been:

user@user:~mist.io$ which haproxy 
/usr/sbin/haproxy
user@user:~mist.io$ ln -s /usr/sbin/haproxy bin/haproxy 

5. start supervisord and make sure all services are up

user@user:~mist.io$ ./bin/supervisorctl status
celery                           RUNNING   pid 24812, uptime 0:00:34
haproxy                          RUNNING   pid 24986, uptime 0:00:04
hub-shell                        RUNNING   pid 24814, uptime 0:00:34
memcache                         RUNNING   pid 24813, uptime 0:00:34
rabbitmq                         RUNNING   pid 24811, uptime 0:00:34
sockjs                           RUNNING   pid 24809, uptime 0:00:34
uwsgi                            RUNNING   pid 24810, uptime 0:00:34

Yep, that got me farther, and I was able to complete the installation.However, now when I start, rabbitmq is "starting" and hub-shell has "EXITED". Rabbitmq's log tells me " Crash dump was written to: erl_crash.dump
Kernel pid terminated (application_controller) ({application_start_failure,kernel,{{shutdown,{failed_to_start_child,net_sup,{shutdown,{failed_to_start_child,net_kernel,{'EXIT',nodistribution}}}}},{k"

and hub-shell's log contains:
No handlers could be found for logger "mist.io.config"

make sure epmd is running. ps aux|grep epmd
If it is not running, then start it with

user@user:~$ epmd -daemon

and then restart the two services

./bin/supervisorctl restart rabbitmq hub-shell

this is a known issue with epmd and erlang

from mist-ce.

yes sir that did the trick. How did I miss the epmd daemon, and how do I make sure that's running when mistio is supposed to be running?

from mist-ce.

Hi, this is a known bug on some systems (Ubuntu/Debian) and erlang, we're trying to see how it can be addressed. If all supervisorctl services are RUNNING you don't have to worry. But if you start all services with ./bin/supervisord and after a few seconds check that rabbitmq and hub-shell are not started, you have to do the above - epmd -daemon && ./bin/supervisorctl restart rabbitmq hub-shell

Sorry for the trouble

What problem are you looking to solve with Mist.io @manderso7?

Trying to get a web front end to manage a kvm homelab.

A note for you devs, the url for haproxy src has been changed, so after changing it in buildout.cfg it works. The correct url: http://www.haproxy.org/download/1.5/src/... instead of the included *.1wt.eu url.
Still working on getting mist.io up and running.

Hi @agentkgb , thanks for the link. The url for haproxy that is contained on buildout.cfg file (http://haproxy.1wt.eu/download/1.5/src/haproxy-1.5.14.tar.gz) is working now, we might replace it with the haproxy.org url however if this is now a more stable url/domain.

Cheers
