How to install and configure a User Interface

3. What is a UI?
The UI is a suite of clients and APIs that users and applications can use to access the gLite services
The gLite UI includes the following components:
– VOMS command-line tools
– Workload Management System clients and APIs
– Logging and Bookkeeping clients and APIs
– Data Transfer command-line clients and APIs
– Data Catalog command-line clients and APIs
– gLite I/O client and APIs
– R-GMA/BDII client and APIs

4. Installing and configuring User Interface (UI)

5. Installation pre-requisites
Start from the base machine you installed in the INTRODUCTORY tutorial for site admin
Verify that all pre-requisites are successfully installed
Install JAVA. Install dependencies if needed.
rpm -ihv
rpm -ihv
Before installing java-1.5.0, the installation of ttmkfdir and chkfontpath will be needed.

6. Installation pre-requisites 1/3
wget -O /etc/yum.repos.d/ca.repo
wget -O /etc/yum.repos.d/gilda.repo
yum install lcg-CA
To install the AFS versions ig_WN and ig_UI profile
yum install openafs openafs-client kernel-module-openafs-`uname -r`

7. Installation pre-requisites 2/3
yum install gilda_utils
Host certificate installation is not necessary …

8. Install and configure UI
We are now ready to install the UI:
export REPOS="ca dag glite-ui ig jpackage gilda”
for name in $REPOS; do wget -O /etc/yum.repos.d/$name.repo; done
yum install ig_UI
cp /opt/glite/yaim/examples/siteinfo/ig-site-info.def /opt/glite/yaim/etc/gilda/<your_site-info.def>

9. Install and configure UI
Edit your file my-site-info.def
vi /opt/glite/yaim/etc/gilda/<your_site-info.def>
Set the variable DOMAIN to your domain, ie, rediris.es
MY_DOMAIN=$(hostname -d) (if you use this sentence, then check if the extended machine name is in /etc/hosts
grid-18.rediris.es grid-18

10. Install and configure UI
Add gilda and geclipsetutor to VOS variable in /opt/glite/yaim/etc/gilda/<your-site-info.def>
cp /opt/glite/yaim/examples/ig-groups.conf /opt/glite/yaim/etc/gilda/
cp /opt/glite/yaim/examples/ig-users.conf /opt/glite/yaim/etc/gilda/

11. Install and configure UI
Append gilda and geclipsetutor users and groups definitions to /opt/glite/yaim/etc/gilda/ig-users.conf
cat /opt/glite/yaim/etc/gilda/gilda_ig-users.conf >> /opt/glite/yaim/etc/gilda/ig-users.conf
cat /opt/glite/yaim/etc/gilda/gilda_ig-groups.conf >> /opt/glite/yaim/etc/gilda/ig-groups.conf

12. Install and configure UI
Define new path of your USERS_CONF and GROUPS_CONF file in /opt/glite/yaim/etc/gilda/<your_site-info.def>
export GROUPS_CONF=/opt/glite/yaim/etc/gilda/ig-groups.conf
export USERS_CONF=/opt/glite/yaim/etc/gilda/ig-users.conf

13. Install and configure UI
Nodetype configuration
/opt/glite/yaim/bin/ig_yaim -c -s /opt/glite/yaim/etc/gilda/my-site-info.def -n ig_UI

14. Add a user into the UI Use the Unix commands: # adduser gildauser
(or any other user name)
# passwd gildauser
Log on it with:
# su – gildauser
(from root)
… or type:
# exit
Then logon with the new user

15. Certificate handling 1/2
Copy your own certificates to the UI:
# From your local PC: ssh
# scp -pr .globus grid-xx.rediris.es:/home/gildauser
Verify permissions of the certificates; they must be:
-r gildauser gildauser 1169 Jun 15 11:03 userkey.pem
-rw-r—r-- 1 gildauser gildauser 1326 Jun 15 11:03 usercert.pem
If file permissions are wrong use:
# chmod 400 userkey.pem
# chmod 644 usercert.pem

16. Certificate handling 2/2
Certificates must be in .globus directory:
# mkdir .globus
# mv *.pem .globus/
How to use more then one certificates:
1) Use a separate account for each certificate
2) Use a symbolic link .globus to different certificate directories
# mkdir .globus_EUMED
# mv *.pem .globus_EUMED/ (EUMED usercert/userkey)
# mkdir .globus_GILDA
# mv *.pem .globus_GILDA/ (GILDA usercert/userkey)
Create the link with:
# ln –s .globus_GILDA .globus
Switch to the EUMED VO with:
# ln –sf .globus_EUMED .globus
