SCALR 3.5 Open Source on Ubuntu 12.04 - INSTALL GUIDE

[Arya A.]

I'm fairly certain this is a work in progress (ie, nowhere near complete and definitely not polished), but it may help someone else out there.

Install prerequisites

apt-get -y install apache2-mpm-prefork php5 php5-mysql php5-curl php5-mcrypt php5-snmp
apt-get -y install libssh2-php apparmor-utils mailutils bind9 phpmyadmin
apt-get -y install php-pear rrdtool librrd-dev libcurl4-openssl-dev mysql-server snmp

Thanks for sharing, Arya. Would you care to add this to the Scalr wiki? Might make it easier for others to suggest improvements.

Sebastian, I'd be happy to, but as far as I can tell, the wiki hasn't been configured to allow public signups.

[Sebastian Stadil]

Really? That's a mistake. Let me change that.

Up to you. Btw, I'm 100% for a community fork. The steps to get a
partially working scalr instance...you weren't kidding when you said
it's hard.

I'm very interested in a chef recipe to get Scalr up and running. I
won't really have time to contribute on that until next month though.

Hi Arya,

about the community fork, a while ago i made a git repo and got an open source license from atlassian, but i didn't have time to go trough it lately. If you are interested you can contact me so we can discuss it. 

Cheers

> > 'scalr-discuss...@googlegroups.com');>.

[Paul Rysevets]

I'm really FOR the community fork,..

I, even, saw it but.. that thing didn't even had php_rrd patch in it :(

and there is something wrong with my GitHub commits(to my fork from the original master). i'd like to share my configurable-bind-path.patch (although it's relatively simple)

[Paul Rysevets]

aand here they are

for BIND

added-CNFIG-variables-for-BIND.patch (11K) 
added-admin-editing-for-bind-paths.patch (1K)

for Empty zones.include file
Fixed-bug-with-Empty-zonesinclude-file.patch (2K)

sorry for that big thingie,.. i've CodeFormatted sources :(

[francesco cislaghi]

Can you push them to the repo?

[Sebastian Stadil]

We released 4.0 recently, you might want to try that since we don't want to backport.

Hi guys,

I realize that this is an old topic but I followed the steps in this thread to install scalr on an Amazon EC2 (within a VPC). I can sign in as admin, create a new user and have this new user setup with Amazon credentials. I also tested the TESTENVIRONMENT.PHP and it passed. My problem is that I can't find a way to change the admin's password. There is no Profile menu option showing at the right upper corner, when you click on the admin icon, there is only the logout option in that menu. But for my regular user id I have a the Profile option and can reset its password whenever I want. Is this a bug or a misconfiguration anywhere ?

anyone has any clues ?

I also tried to change the password directly to the account_user table but it did not work, still have the default password working.

by the way the the version is listed as 3.6.0.

If this is not the right place to ask this I apologize.

Regards,

i am running the earlier version of Scalr.  After login as admin, if i click on the admin icon i get a profile option.  This could be a bug.

Thank you so much! We have a great many surprises in store for everyone and can't wait to share.

4.0 is on github: https://github.com/Scalr/scalr

Importing servers into Scalr is possible regardless of deployment method (enterprise, open source, hosted). So you should be fine.

To your second point, Scalr <-> Scalarizr communication is required for Scalr to manage your infrastructure; if the communication is impeded, you'll get Alerts in the Scalr interface.

Thanks Srini,

I just went back to 3.5 and the admin password issue is gone.

I am really new to Scalr. I have a few EC2 instances (actually Images - but you get the point) on Amazon that I'd like to get them organized under a Scalr Farm. They are windows and linux servers. I am trying to use Scalarizr and am failing miserably.

First question I have about Scalarizr is that if it is supposed to work with a scalr "standalone" installation ?? I mean, importing servers to roles are only possible if one pays for scalr.net services ?

Sencond is, what type of message I should see in the logs that would confirm conectvity between Scalr and Scalarizr. I have ports 8010 and 8013 opened both ways on both servers. Also have the 8014/UDP opened. I can't really see anything wrong in Scalarizr logs. The operation hangs and never finishes.

From scalr dashboard it only shows the attemptive of conection, it never connects.

Happy new year guys.

Can you direct me to the link of 4.0 ?

Thanks for the info Sebastian.

Is there anyway to setup the logs for more details ? Or setup other logs usefull to debug the problem ??

In Scalr interface it keeps saying that is attempting to connect to the server, but never does. How long should I wait till it says Connected or gives out an error ?

In the linux box I see the status of importing from the standard output but hours later and nothing changes, In the windows box it doesn't go that far.

I will be checking the version 4.0...

Really appreciate the help. Thanks again.

Have you set the Scalr URL in the admin settings? You can also try to telnet to the diff ports to make sure they are open.

Hi Srini,

Yes, I have the Scalr URL setup and also already tried the telnet and everything seems allright. That is why am asking about logs, 

Thank you...

[Srinivasan S]

To check if your setup is fine you can create a dummy farm and run an application role with a micro instance. If it connects and all is well then you can move to your custom role. Easier to troubleshoot a standard role.

If I remember well logs are by default verbose unless you changed them in scalr. Look for php file with log config.

Hi Srini,

I can create the farm but when lauching it keeps on pending-launch status and on AWS nothing happens. 

What should I check in cases like this ?

Yes, they are setup, under user ID scalr.

[Srinivasan S]

If nothing is happening on AWS my guess is that the cron jobs are not running. Do a top and check if you see a number of php processes starting up. That is an easier way of checking cron than logging.

You can also login as admin and view the syslog. That has all the messages.

Yes, I can see a bunch of php processes running from time to time. On syslog I see a problem with user scalr accessing the postfix config file:

Shouldn't be. Can you login to scalr as admin and check the system log?

Hi Srini,

I assume I have installed it correctly but being a first timer, I find it hard to believe that I got it up and running flawless. :-)

Is there anything that we can check to see if I got things right ?

[Srinivasan S]

What I meant to ask was is your ec2 credentials etc setup correctly? Can you browse to you aws a/c from scalr web site. For eg s3 browser.

Its hard to understand why nothing happens on AWS if all is configured correctly :)

I understand. thanks for helping.

I gave up. Terminated the EC2 I was setting up scalr into. Launched another ubuntu 12.04 instance and restarted the install process.

I will let you know the outcome.

[Sebastian Stadil]

That's normal behavior. Simply terminate this server and create a farm with its role in it and you'll be fine.
