Cloud template

  • change BUCKET_CLUSTER, BUCKET_DEFAULT, CLUSTER_NAME if a different bucket name is used at the cloudman script download site. For example https://cloudman-on.dtls.nl/cloudman-on
  • Once the hosting site of the bucket is moved, you also need to check/modify the following two variables in /opt/cloudman/pkg/ec2autorun.py
SERVICE_ROOT = 'http://cloudman-on.dtls.nl' 
DEFAULT_BUCKET_NAME = 'cloudman-on' # Ensure this bucket is accessible to anyone!
  • PASSWORD is set to have authentication on cloudman UI login. The default username is "admin"
  • NETWORK=nbicgalaxy is set to obtain a static IP for NBIC Galaxy:
 TESTFLAG=false ]
 IMAGE_UNAME=hailiang.mei@nbic.nl ]
 TYPE=vnc ]
NAME="NBIC Galaxy"
 NETWORK_UNAME=oneadmin ]
 NETWORK_UNAME=hailiang.mei@nbic.nl ]
 BOOT=hd ]
 TYPE=kvm ]

VM Shutdown and Start Instructions

In order to stop the running VM at the SARA cloud and save it into a image file, we need to shutdown the VM and restart a new instance. Below are the steps:

  1. Log into cloud management console: https://ui.cloud.sara.nl/
  2. Verify the existence of a "save as" image of the current running VM, e.g. "GalaxyMaster_2012_10_18"
  3. Shutdown the VM
  4. Update "IMAGE=GalaxyMaster_2012_10_18" in the template "NBIC Galaxy"
  5. Remove cloudman-on.dtls.nl/cloudman-on/cm.tar.gz
  6. Update "IMAGE=GalaxyMaster_2012_10_18" in cloudman-on.dtls.nl/cloudman-on/cm/clouds/opennebula.py and recreate cm.tar.gz using the cm directory.
    sudo tar czf cm.tar.gz cm
  7. In the cloud management console, initiate a new instance of the template "NBIC Galaxy".
  8. In the cloud management console, select the running VM, click button "Update Properties" and give the "group" access to "use" and "manage" the VM
  9. Once the new VM is running, you could log into it and start the lanch of Cloudman service (including Galaxy)
  10. save the VM into a new image using "save as" and name it as "GalaxyMaster_yyyy_mm_dd".

Cloudman Startup Instructions

You need to restart cloudman in case the VM is restarted.

  • stop the running cloudman process
sudo sh /mnt/cm/run.sh --stop-daemon
  • kill the hanging Galaxy process that still occupies the Galaxy port if necessary
sudo kill -9 `sudo fuser -n tcp 42284`
  • kill all running sge process (let cloudman handle the start of SGE)
sudo pkill -U sgeadmin
  • update /etc/hosts with master node's internal IP address
ifconfig eth1
sudo vim /etc/hosts and replace the line
10.0.137.xxx	ubuntu
  • if there are lines specifying worker nodes in /etc/hosts, remove them
  • if you updated the IP address in the previous step: restart rabbitmq server
sudo pkill -U rabbitmq
sudo /etc/init.d/rabbitmq-server start

  • start cloudman script
sudo sh /mnt/cm/run.sh --daemon
  • go to http://galaxy.nbic.nl/cloud and login with admin/{default password} to initiate the launch of cloud Galaxy. When it asks you for the 'initial storage' just ignore this and click on the 'cloudman' button at the bottom of the pop-up.
  • Check the log file /mnt/cm/paster.log to see if cloudman services (including postgres, SGE, Galaxy) start successfully.

Galaxy Startup Instructions

Start and stop Galaxy only.

sudo /bin/su - galaxy -c "export SGE_ROOT=/opt/sge; sh /mnt/galaxyTools/galaxy-central/run.sh --stop-daemon"
sudo /bin/su - galaxy -c "export SGE_ROOT=/opt/sge; sh /mnt/galaxyTools/galaxy-central/run.sh --daemon"

Galaxy Update Instructions

When PennState Galaxy team releases new versions, we need to update our Galaxy codebase.

Stop the service

  1. lock the job submission at the NBIC Galaxy server via the admin UI.
  2. Stop the Galaxy daemon.
sudo /mnt/galaxyTools/galaxy-central/run.sh --stop-daemon

Download new release of Galaxy

Galaxy codebase is located at /mnt/galaxyTools (which is a NFSv4 mount of the cloud VM. All mount points are owned by user "postgres" as a workaround to support cloudman and postgres service)

  • go to the directory of /mnt/galaxyTools/sources/ and check out the latest code (central version) from Penn State:
hg clone https://bitbucket.org/galaxy/galaxy-central galaxy-<year>-<month>-<date>

Note: this is just a copy for reference. Do not modify this copy!

  • Copy this folder to /mnt/galaxyTools/. This will become the active installation with local mods.
cp /mnt/galaxyTools/sources/galaxy-<year>-<month>-<date> /mnt/galaxyTools/ -r
  • Update the Galaxy symbolic link
cd /mnt/galaxyTools
rm galaxy-central
ln -s galaxy-<year>-<month>-<date>/ galaxy-central

Backup the Galaxy DB

Start the database service if it is not running (e.g., stopped by the cloudman script.)

sudo su postgres
/usr/lib/postgresql/9.1/bin/postgres -D /mnt/galaxyData/pgsql/data -p 5840

Backup the current galaxy DB.

sudo su postgres
pg_dump -p 5840 galaxy > galaxyDB_backup.out

Update database

  • Configure the new galaxy: we keep the all the files (datasets) associated with histories stored in the Postgres database in a separate database folder outside the galaxy root folder.
cd /mnt/galaxyTools/galaxy-central
rmdir database 
# Note: make sure this is the EMPTY database folder of the new install and not 
# a symlink pointing to our data in /opt/galaxy/data/database/
ln -s /mnt/galaxyData/database database
  • Test starting up the cloudman/Galaxy server (and fetch/check eggs if necessary)
sudo /mnt/cm/run.sh --daemon

Copy NBIC tools and data

  • Customize the new Galaxy: We keep copies of modified (config) files in the conerice repository. You should diff our customized versions in the conerice repo with the new versions in Galaxy. When necessary merge updates from the Galaxy developers with our local customizations and commit a new version to the conerice repo. If there are no changes you can simply copy the files below:
cd /mnt/galaxyTools/sources/
svn update conerice
cp conerice/masterfiles/galaxy/sombrero/static/welcome.html              /mnt/galaxyTools/galaxy-central/static/
cp conerice/masterfiles/galaxy/sombrero/config/universe_wsgi.ini          /mnt/galaxyTools/galaxy-central/
cp conerice/masterfiles/galaxy/sombrero/config/tool_data_table_conf.xml          /mnt/galaxyTools/galaxy-central/
cp conerice/masterfiles/galaxy/sombrero/config/tool_conf.xml              /mnt/galaxyTools/galaxy-central/
cp conerice/masterfiles/galaxy/sombrero/config/shed_tool_conf.xml          /mnt/galaxyTools/galaxy-central/
cp conerice/masterfiles/galaxy/sombrero/config/datatypes_conf.xml          /mnt/galaxyTools/galaxy-central/
cp conerice/masterfiles/galaxy/sombrero/lib/galaxy/datatypes/registry.py  /mnt/galaxyTools/galaxy-central/lib/galaxy/datatypes/
cp conerice/masterfiles/galaxy/sombrero/tools/data_source/upload.py       /mnt/galaxyTools/galaxy-central/tools/data_source/
  • Create symlinks for our tools and datatypes from the NBIC Galaxy Module Repository
cd /mnt/galaxyTools/sources/galaxytools
svn update
svn export trunk /mnt/galaxyTools/nbic_gmr
cd /mnt/galaxyTools/galaxy-central/tools
ln -s /mnt/galaxyTools/nbic_gmr/ nbic_gmr
cd /mnt/galaxyTools/galaxy-central/static/images
ln -s /mnt/galaxyTools/nbic_gmr/data/image-links/ nbic_gmr
cd /mnt/galaxyTools/galaxy-central/lib/galaxy/datatypes/
for item in $(ls /mnt/galaxyTools/nbic_gmr/data/datatypes/); do ln -s /mnt/galaxyTools/nbic_gmr/data/datatypes/$item; done
  • Create symlinks for custom tool-data files in /mnt/galaxyTools/galaxy-central/tool-data/
cd /mnt/galaxyTools/galaxy-central/tool-data/
for item in $(ls /mnt/galaxyData/tool-data/); do ln -s /mnt/galaxyData/tool-data/$item; done

Restart the service

sudo /mnt/cm/run.sh --daemon
  • Check the log file /mnt/galaxyTools/galaxy-central/paster.log to see if Galaxy started (without errors).

Useful tips

Creating new user accounts

To keep the server safe it is important to have a policy on the user accounts.

  • Create a new user with the following command (replace group1,group2 and user with the correct values of course, if no special group memberships are necessary, you can omit the -G ...)
sudo useradd -G sudo -m -U -b /home -s /bin/bash -c 'Full name of the user' username
  • Always use a strong password on user accounts (8 or more characters and use letters, numbers and specials). Set the initial password with
sudo passwd user
  • When you create an account and have to e-mail the password to the user enforce a password change on first use with the following command:
sudo chage -d 0 user
  • When you are giving temporary access to someone set an expiration date for the account with the following command:
sudo chage -E YYYY-MM-DD user
  • make sure the user is member of the right groups. Users who need to have access to galaxy need to be in the devs group, but only give group membership if it is really necessary. Anyone who is member of the devs group can potentially break stuff...
  • To change the group memberships later on you can use the following command:
sudo usermod -a -G devs user

HPC cloud status

Sometimes it is handy to check the system status in the cloud.

The file-server that serves the virdirs (NFS): https://ganglia.surfsara.nl/?c=Calligo-Services&h=m-fileserver01.calligo.sara.nl&m=load_one&r=hour&s=by%20name&hc=4&mc=2

The file-server that serves the VM images: https://ganglia.surfsara.nl/?c=Calligo-Services&h=m-fileserver02.calligo.sara.nl&m=load_one&r=hour&s=by%20name&hc=4&mc=2
