    When I try 

    sudo apt-get install rabbitmq-server


    it asks for a password. It doesn't seem to matter what goes there because I always get

    Quote:
    Setting up rabbitmq-server (1.7.2-1ubuntu1) ...
    Starting rabbitmq-server: TIMEOUT - check /var/log/rabbitmq/startup_{log,err}
    rabbitmq-server.

    The log says authentication failure.

    Purged and tried again. Same thing.

    on UBUNTU Lucid updates applied

    OK the issue is actually the rabbitmq server is hanging on start-up. Played around with the hosts file as per various posts but still hanging. Any ideas?

    We have install RabbitMQ on both Ubuntu 10.04 and 10.10, on multiple
    machines, without any problems. Please let us know if you find the cause of
    this....

    It's a weird one. If I run essentially what the init script start command does:

    sudo /usr/sbin/rabbitmq-multi 1


    I get the normal sudo password prompt and then another one. After that fails I get

    Quote:
    su: Authentication failure


    This must be the password for the rabbitmq user?

    Still digging...

    Verheek, any luck? Have you tried this solution?:

    Hi Martin,

    I took a weekend break from it. I spent a lot of Friday trying similar solutions to the one you linked to. But from what I could figure, the error is not related to the hosts file but to changing to the rabbitmq user with su.

    Quote:
    $ cat /var/log/rabbitmq/startup_err
    Password:
    su: Authentication failure


    If you dig into /var/lib/dpkg/info/rabbitmq-server.postinst, you find the above command to start the server. This is when it asks for a password. It's the same password prompt encountered when trying to install rabbitmq from the .deb

    Repairing the install also sticks at starting the server.

    The error is mentioned above.

    My next idea was to delete the rabbitmq user but it seems to be removed with

    $ sudo apt-get purge rabbitmq


    Installing again with

    $ sudo apt-get install rabbitmq
    results in the same output as the above when -f was used.

    Ok I changed the password on the rabbitmq user, ran apt-get install -f to repair the rabbitmq install, typed in that password and it started. Then I ran apt-get purge rabbitmq, typed in the password and tried again and then it uninstalled. When I install again, I'm back to the password prompt when it starts the server.

    Weird...but at least I can get it going. What is the rabbitmq user password and why is it prompting for it when starting the server?

    Ok after _alot_ of digging I got this to install without changing the rabbitmq user password.

    One was this post https:// bugs.launchpad.net/ubuntu/+source/shadow/+bug/735341?comment s=all to reset the root account expiry. This allowed the --gecos option to work when adding a user in the rabbitmq.postinst script.

    The other was this thread http://ubuntuforums.org/showthread.php?t=819198 about creating accounts with blank passwords. This allowed 
    /etc/init.d/rabbitmq-server start
    to work by typing 
    sudo sed -i 's/nullok_secure/nullok/' /etc/pam.d/common-auth


    Studying rabbitmq.postinst, the password is blank. Changing it to a non-blank password or permitting blank passwords in PAM allows the server to switch to the rabbitmq user and start.

    The question is why there a difference between my setup and a clean install that requires these steps?

    Jeremy,

    Luckily you seem to be the only user to far to experience this issue, so let's hope this is an isolated case.

    So your system isn't a clean install or it is?

    Well it was a clean install last fall ... Smile

    But a lot of experimenting and playing around has occurred while developing a web radio host.

    Does Lucid allow for null passwords by default in PAM? This option may have been removed by a hardening blog I followed at some point. That's what this particular issue boiled down to. I posted a "bug" in Ubuntu but it may not be considered one although I think there needs to be a modification so that the install does use a static password for the rabbitmq user.

    I had a copy of this VM with the same issue. After adding the null_ok option in PAM it also allowed the rabbitmq install to work normally. Case closed.

    I have a similar problem now trying to install the latest airtime-dev (git pull origin master). I get a password each time it tries to create the airtime user. I have changed the postgres user password to postgres so I can at least get past the password prompt but the install still fails in that area.

    I don't want to use null_ok in pam.d because of security but would prefer nullok_secure which apparently only allows blank passwords for terminals listed in securetty.

    sudo sed -i 's/nullok_secure/nullok/' /etc/pam.d/common-auth

    sudo passwd -d postgres blanked the password for postgres

    Now the install works.

    More work on this because I didn't want nullok in my common-auth as it's less secure. What I found was that my su file in /etc/pam.d was missing. Restoring this from a fresh Ubuntu Lucid install fixed the password prompt during install when creating users with blank passwords.

    Re: http://wiki.sourcefabric.org/display/CC/FAQ+and+Support

    Hi Paul and all the list!

    I was migrated from Campcaster 1.6 to Liquidsoap, because CC was has an
    issue with using without a physical audio board. So, now I am running LS
    and I suppose in the next few months I will back to the new Airtime again!.

    So, my question is: What is the real use of RabbitMQ into Airtime? I
    can't figured, but I am interested to known the use.

    RabbitMQ is used to pass messages from the PHP interface to the audio
    playout backend (pypo).

    Hello,

    I've experienced the same Permission Denied error.

    $ /etc/init.d/rabbitmq-server start
Starting rabbitmq-server: sh: /var/log/rabbitmq/startup_log: Permission denied
FAILED - check /var/log/rabbitmq/startup_{log, _err}
rabbitmq-server.

    I tried
    - Changing nullok_secure values, but i missed the point and messed with the ssh authentification
    - Creating the rabbitmq.conf file, with no results
    - Update the postgres password, with no results as well.

    Many thanks.

    I get this error too if I run

    as a non-root user.

    Try: 
    $ sudo service rabbitmq-server start


    The underlying program rabbitmq-multi has to be started as root or rabbitmq. Starting the service with sudo allows it to do the rest with the script.

    i figured it out make sure your host name is setup correctly if setup at all it should look like this

    127.0.0.1 example.domain.com example

    If not

    $ nano /etc/hosts

    well long story short... same issue... tried the host file solution, well nothing to do there since it is correct on my end. Also thought it might be a permission issue with rabbitmq but it wasnt. However research shows this to be an issue over at rabbitmq developers since it has to do with invoking the server then applying the conf file, well something to that effect ... this appear to be a major kick in the but ... and a real monkey wrench in my plans.... since it messes up airtime in many ways... 

    I have a dev system in vbox which is fine... i copied over the conf(s) changed the hostnames and etc... guess what... same issue..

    Might be some other issue(s) too... perhaps python/perl/php/etc update from canonical/ubuntu... maybe not.. anyway..

    in the post above i attached my log if it helps somehow...
    Well I guess i'll need to figure out an alternative for my project/site for now..... but I've been following airtime for sometime very promising.... cant wait for a fix..

    Well I figured out the issue.. After a short break and a good nights reset, I noticed that there was a so called ghost operation of rabbitmq as well for some reason the hidden backup file of its conf file... Also a bit of the issue was my local firewall... disabling the fw add deleting the ~rabbit... conf. terminating the running process, purged apt-get removed  autoclean and the such and last but not least .. which was a pain for my clients a shutdown and cold boot. also a side not ensure that your interface file (server lockdown procedures) are not a part of the issue... since that was a part  of my issue as well... forgot too lighten up a bit... but after all this re install and bamm.... just works fine... I hope this might be of help for those who do not want to do or go through a whole fresh re-install.....

    This is a problem related to /etc/host file not with rabbitmq-server. This file (/etc/host) is not configure properly.

    Just open the file :

    $ sudo -s

    vim /etc/hosts

    and check line start with "127.0.0.1" in this file ( usually it's located on the top of the file)

    make it like as below:

    127.0.0.1 your host name

    save and quit.

    now restart rabbitmq-server and certainly it should work.

    Just for be sure, take a look to your local network

    # ip add

    If there's no "lo" network, the you should enable it:

    # ifconfig lo up

    Then restart the server again and let's see if it works again now

    # systemctl start rabbitmq-server
