How to install openlava in Ubuntu

1) prerequisite:
    sudo apt-get install python-software-properties         
   
2) add ppa
    sudo add-apt-repository ppa:cansmith/ol

3) update repository
    sudo apt-get update

4) install openlava
    sudo apt-get install --yes openlava

5) edit /etc/hosts: the first line
from
    127.0.0.1       localhost
to
    127.0.0.1       myhostname  localhost

6) setup configuration
- Go to openlava directory
    cd /etc/openlava/
- open openlava.sh
    sudo vi openlava.sh
- change
    LSF_ENVDIR=/usr/etc
  to
      LSF_ENVDIR=/etc/openlava
- source it
    . ./openlava.sh
- add it to ~/.bashrc
    echo ". /etc/openlava/openlava.sh " >> ~/.bashrc
     
7) check openlava status in /etc/openlava
    sudo ./openlava status
the output must look like
lim pid: <>
res pid: <>
sbatchd pid: <>
lim mbatchd: <>
(without any numbers in <>)

8) start openlava
    sudo ./openlava start
the output must look like
Starting daemons...
lim started
res started
sbatchd started

9) Check a couple of commands:
albertsk@heyum:openlava$ bhosts
HOST_NAME          STATUS       JL/U    MAX  NJOBS    RUN  SSUSP  USUSP    RSV
heyum              ok              -      8      0      0      0      0      0


albertsk@heyum:openlava$ bjobs
No unfinished job found

albertsk@heyum:~$ bhist
No matching job found

10) run the first job
- go to home directory
    cd
- make a test directory
    mkdir bsub
    cd bsub
- edit a job file job.bsub:
#BSUB-q normal                  # Job queue
#BSUB-J myfirstjob              # name of the job
#BSUB -o lava-%J.out
#BSUB -e lava-%J.err
hostname
pwd
ls -laF

- submit the job
    bsub < job.bsub
- try following commands: bjobs, bhist, bpeek
