looking for euca2ools... error: failed to find required euca2ools - Eucalyptus 3.2


Currently I am working in Eucalyptus 3.2.

I have a single system with all the Eucalyptus components configured in that.

Cloud Controller, Cluster Controller, Walrus, Storage Controller,
Node Controller in the Same system.

I was able to install and configure Eucalyptus 3.2 from Source in
Debian (    BOSS GNU/Linux 2.0 (server) )after a hell lot of errors !.

I referred this blog for installing from the source,

http://mdshaonimran.wordpress.com/2012/10/31/eucalyptus-source-installation/



This blog was very much helpful  to me.

I configured all the components and only Node Controller was pending.

I am using Xen 4.1( xen-hypervisor-4.1-amd64 ) for Virtualization.

When I started Node controller,

/etc/init.d/eucalyptus-nc start

I ended up with following error ,

Starting Eucalyptus services: eucalyptus-nc

Node Controller cannot be started: errors in //var/log/eucalyptus/euca_test_nc.log

When I checked the log, It showed the following.

root@boss[console]#cat //var/log/eucalyptus/euca_test_nc.log

looking for euca2ools...
error: failed to find required euca2ools


When  I searched google, I came across this website,

http://fossies.org/linux/misc/eucalyptus-3.1.2.tar.gz:a/eucalyptus-3.1.2/node/test_nc.c

Refer the lines,
211-216

Line Number 213,was having the fprintf statement

 fprintf (stderr, "error: failed to find required euca2ools\n");

 
The previous line, 212 is having the condition as follows

if (verify_helpers (helpers_name, NULL, 3) > 0) {

Now I checked the  helpers_name  variable.It contained 

  199     fprintf (stderr, "ok\n\nlooking for euca2ools...\n");
  200     static char * helpers_name [3] = {
  201         "euca-bundle-upload",
  202         "euca-check-bucket",
  203         "euca-delete-bundle"
  204     };
  205  

So when we are staring eucalyptus-nc, it checks for the existence of the command,

euca-bundle-upload

euca-check-bucket

euca-delete-bundle

Now I searched for the above commands in my system.

Some of the commands were located in 

/usr/local/bin 

I already had an older version of euca2ools

root@boss[~]#dpkg -l |grep euca2ools
ii  euca2ools         1.2-1     managing cloud instances for Eucalyptus

When I executed the command,euca-delete-bundle

I got the following error.

root@boss[~]#euca-delete-bundle 
Traceback (most recent call last):
  File "/usr/bin/euca-delete-bundle", line 37, in <module>
    from euca2ools import Euca2ool, FileValidationError, Util
ImportError: cannot import name Euca2ool

Now I checked location of this command,that was  referring to /usr/bin .

root@boss[~]#which euca-delete-bundle 
/usr/bin/euca-delete-bundle

Move the file to some other location.

mv /usr/bin/euca-delete-bundle /usr/bin/euca-delete-bundle.old

Then I replaced this link with 

ln -s  /usr/local/bin/euca-delete-bundle /usr/bin/

I did the same for the commands, euca-check-bucket and euca-delete-bundle

Also I updated the PATH variable in /root/.bashrc

export PATH=$PATH:/usr/local/bin

Now I exited from the terminal and opened a new terminal

Execute the following commands. 

source /root/.bashrc

/etc/init.d/eucalyptus-nc restart

Restarting Eucalyptus services
 

At last eucalyptus-nc started successfully ! 

Now I am proceeding to registering the nodes , uploading images and launching instances.

However I anticipate issues in the upcoming tasks ! .
