1 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America Instalación y configuración de CE+WN Alicia Acero Fernández CIEMAT 6 th EELA Tutorial Madrid 16-20/10/2006

2 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, What is a Computing Element (CE) ? What is a Torque Server ? What is a Worker Node? How to install and configure a Computing Element with Torque Server. How to install and configure a Worker Node with Torque Computing Element Testing Outline

3 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, What is CE? The CE is a service representing a computing resource. Its main functionality is job management (job submission, job control, etc.). For job submission, the CE can work in: –push model –push model (where the job is pushed to a CE for its execution). –pull model –pull model (where the CE asks the WMS for jobs).

4 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, What is Torque? TORQUETORQUE (Tera-scale Open-source Resource and QUEue management) is a resource management providing control over batch jobs and distribuited compute resource. The Torque System is composed by a: –pbs_server –pbs_server which provides the basic batch services such as receiving/creating a batch job or protecting the job against system crashes. –job_scheduler –job_scheduler which contains the site's policy used to decide which job must be executed. –pbs_mom –pbs_mom which places the job into execution. It is also responsible for returning the job’s output to the user.

5 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, What is a Worker Node? The Worker Node (WN) is a set of clients required to run jobs sent by the CE via the Local Resource Management System. It currently includes the: –gLite I/O Client, –the Logging and Bookkeeping Client, –the R-GMA Client and –the WMS Checkpointing library.

6 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, Installing CE + Torque Server WN + Torque

7 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, Preliminary and common steps Start from an instalation of SLC 3.0.X Install JAVA SDK Install and configure ntp daemon Install the latest version of YAIM Install the latest version of GILDA YAIM Install X.509 host certificates (it is necessary for CE, SE and RB) /etc/grid-security and check their file permissions. Install the middleware

8 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, Installing pre-requisites JAVA is not included in distribution. Install it separately (>= 1.4.2_08) chmod +x j2sdk-1_4_2_12-linux-i586-rpm.bin./j2sdk-1_4_2_12-linux-i586-rpm.bin rpm -ivh j2sdk-1_4_2_12-linux-i586.rpm Preparing... ########################################### [100%] 1:j2sdk ########################################### [100%]

9 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, Installing pre-requisites Depending on the packages set you selected when installing the operating system, it may be possible that lam package is installed on your WN. Please remove lam. apt-get remove lam There is a known installation conflict between the 'torque-clients' rpm and the 'postfix' mail client (Savannah. bug #5509). If you are going to install Torque, uninstall postfix package apt-get remove postfix Check the FQDN hostname –Ensure that the hostnames of your machines are correctly set. Run the command: hostname -f

10 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, Installing pre-requisites Download and install latest version of glite-yaim- latest.rpm on all your grid nodes: deployment/gis/yaim/ rpm -ivh glite-yaim-latest.rpm Download and install the latest version of gilda_ig- yaim-latest on all your grid nodes: rpm –ivh gilda_ig-yaim-latest

11 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, Installing pre-requisites Request host certificates for the CE to a CA – https://gilda.ct.infn.it/CA/mgt/restricted/srvreq.phphttps://gilda.ct.infn.it/CA/mgt/restricted/srvreq.php Create the directory /etc/grid-security and copy host certificates (hostcert.pem and hostkey.pem) in it. Change the permisions –chmod 644 hostcert.pem –chmod 400 hostkey.pem If you plan to use certificates released by unsupported EGEE CA’s, be sure that their public key and CRLs (usually distributed with a rpm) are installed. –The CRL of the VO GILDA are available from https://gilda.ct.infn.it/RPMS/ca_GILDA i386.rpm

12 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, Installing pre-requisites Syncronization among all gLite nodes is mandatory. Install ntp if not already available for your system: – apt-get install ntp – yum install ntp Add your time server in /etc/ntp.conf –restrict hora.rediris.es mask nomodify notrap noquery –server hora.rediris.es –(you can use ntp-1.infn.it – IP ) Edit /etc/ntp/step-tickers adding your(s) time server(s) hostname If you are running a firewall, you will have to allow inbound comminication on the NTP port: –-A INPUT -s -p udp --dport 123 -j ACCEPT Activate the ntpd service with the following commands:  ntpdate  service ntpd start  chkconfig ntpd on –You can check ntpd’s status with :  ntpq -p

13 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, Installing CE+Torque Server All the configuration values to sites have to be configured in a site configuration file (site-info.def) using key-value pairs. This file is shared among all the different gLite node types. So edit once and keep it in a safe place Create a copy of /opt/glite/yaim/examples/gilda_ig-site- info.def template (coming from the lcg-yaim RPM) to your reference directory for the installation (e.g. /root): – cp /opt/glite/yaim/examples/gilda_ig-site-info.def /root/my-site-info.def A good syntax test for your site configuration file is to try to source it manually running the command: – source my-site-info.def

14 FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, Customize gilda_ig-site-info.def Open file /root/my-site-info.def and set the values according to your grid environment: MY_DOMAIN=fdi.ucm.es CE_HOST=grid-xx.$MY_DOMAIN RB_HOST=arquimedes.rediris.es WMS_HOST=glite-rb.ct.infn.it PX_HOST=grid001.ct.infn.it BDII_HOST=euclides.rediris.es MON_HOST=aliserv6.ct.infn.it FTS_HOST=fts.ct.infn.it REG_HOST=rgmasrv.ct.infn.it :
