A
recent comment lead me to make this post:
[..]
Can you advise a correct way of setting up ECCE so that everyone can have an individual account and run on the same machine?
It's a valid question. I haven't had any need for it since I'm running my own cluster, which I currently don't share with anyone. I also manage a multi-user cluster overseas, but I am the only one using ECCE, and so I'm fine running the ECCE server here.
Anyway. I built ECCE 6.4 as shown e.g.
here and
here.
Below I install the ECCE server as the user verahill, and then install the client software as the users lindqvst and me. In the former case I configure the server using a copied
config_from_server script, and in the latter case I use
config_with_server. Both methods worked fine. All users are on the same machine, but by editing apps/siteconfig/DataServers you can quite easily configure the ECCE client to connect to a remote server.
Server:
hostname
helium
sudo adduser verahill
sudo adduser lindqvst
./install_ecce.v6.4.csh
Main ECCE installation menu
=========================== 1) Help on main menu options
2) Prerequisite software check
3) Full install
4) Full upgrade
5) Application software install
6) Application software upgrade
7) Server install
8) Server upgrade
IMPORTANT: If you are uncertain about any aspect of installing
or running ECCE at your site, please refer to the detailed
ECCE Installation and Administration Guide at
http://ecce.pnl.gov/docs/installation/2864B-Installation.pdf
Hit at prompts to accept the default value in brackets.
Selection: [1] 7
Host name: [helium]
Server installation directory: [/home/verahill/ecce-v6.4/server]
Enter the path to the ECCE application software directory that
will use this server (even if this directory is not accessible
from the current machine) or [return] if you have not installed
application software yet or don't want to update it:
ECCE v6.4 will be installed using the settings:
Installation type: [server install]
Host name: [helium]
Server installation directory: [/home/verahill/ecce-v6.4/server]
Are these choices correct (yes/no/quit)? [yes]
ECCE installation succeeded.
***************************************************************
!! You MUST perform the following steps in order to use ECCE !!
-- Transfer the script:
/home/verahill/ecce-v6.4/server/ecce-admin/config_from_server
to the machine where the application software is installed.
Run this script as the same user as the application
software installation.
(This step can be skipped if you have not installed the
application software and the server name is specified during
that install)
-- Start the ECCE server as 'verahill' by running:
/home/verahill/ecce-v6.4/server/ecce-admin/start_ecce_server
***************************************************************
cp /home/verahill/ecce-v6.4/server/ecce-admin/config_from_server ~
chmod ugo+r config_from_server
First client
su lindqvst
cd ~
cp /home/verahill/config_from_server .

Selection: [1] 5
Host name: [helium]
Server installation directory: [/home/lindqvst/ecce-v6.4/apps]
ECCE installation succeeded.
***************************************************************
!! You MUST perform the following steps in order to use ECCE !!
-- Configure the application software to use the desired ECCE
server by running the script:
/home/lindqvst/ecce-v6.4/apps/scripts/config_with_server
as the same user as the application software installation.
(This step can be skipped if you prefer to copy over and run
the config_from_server script created during the server
installation in the ecce-admin directory)
-- To register machines to run computational codes, please see
the installation and compute resource registration manuals
at http://ecce.pnl.gov/using/installguide.shtml
-- Before running ECCE each user must source an environment
setup script. For csh/tcsh users add this to ~/.cshrc:
if ( -e /home/lindqvst/ecce-v6.4/apps/scripts/runtime_setup ) then
source /home/lindqvst/ecce-v6.4/apps/scripts/runtime_setup
endif
For sh/bash users, add this to ~/.profile or ~/.bashrc:
if [ -e /home/lindqvst/ecce-v6.4/apps/scripts/runtime_setup.sh ]; then
. /home/lindqvst/ecce-v6.4/apps/scripts/runtime_setup.sh
fi
***************************************************************
Next, configure:
./config_from_server
Enter the ECCE application software installation home directory: /home/lindqvst/ecce-v6.4/apps
ECCE application software home directory is /home/lindqvst/ecce-v6.4/apps
Is this correct? [yes]
Adding data server URL for helium to siteconfig/DataServers
Adding URL for online help to siteconfig/site_runtime
Adding message server URL for helium to siteconfig/jndi.properti
And then do
echo 'export ECCE_HOME=/home/lindqvst/ecce-v6.4/apps' >> ~/.bashrc
echo 'export PATH=${ECCE_HOME}/scripts:${ECCE_HOME}/scripts/parsers:${PATH}' >> ~/.bashrc
Second client:
I set up a third user, installed ECCE as shown above for lindqvst, but instead of running config_from_server
I did:
/home/me/tmp/ecce-v6.4/ecce-v6.4/apps/scripts/config_with_server
Enter the full host name of the machine where the ECCE server
is installed: helium
ECCE server host name is helium
Is this correct? [yes]
And then do
echo 'export ECCE_HOME=/home/me/ecce-v6.4/apps' >> ~/.bashrc
echo 'export PATH=${ECCE_HOME}/scripts:${ECCE_HOME}/scripts/parsers:${PATH}' >> ~/.bashrc
source ~/.bashrc
Tying it all together:
Start the server:
As user verahill, start the server.
su verahill
/home/verahill/ecce-v6.4/server/ecce-admin/start_ecce_server
/home/verahill/ecce-v6.4/server/httpd/bin/apachectl start: httpd started

You should be able to autostart ecce using something along the lines of the following in your /etc/rc.local:
su verahill '/home/verahill/ecce-v6.4/server/ecce-admin/start_ecce_server' &
As a user, start ecce:
su lindqvst
/home/lindqvst/ecce-v6.4/apps/scripts/ecce
 |
| Create a password |
 |
| Create a job |
Then log out and log in as another user, e.g.
me
su me
ecce
 |
| me is in reality called something else |
Note that as user
me you can't see any of the files in lindqvst's folder -- nor access them without inputting the correct (ECCE) username and password.
And again, note that there are alternative ways of setting this up -- you could have everyone log in as the same linux user, but still retain different ECCE identities. I think what I show here is more in line with how most people would want to use ECCE though.
Also, note that you can quite easily be a client on a different computer too -- the key lies in editing the apps/siteconfig/DataServers file.
