Instalação da spserv01 e migração da osg-ce

Description

• Servidor NIS

Copiados os /etc/passwd,/etc/shadow,/etc/gshadow e /etc/group

yum -y install ypserv
ypdomainname grid
/etc/init.d/ypserv start
cd /var/yp
make
chkconfig ypserv on
vim /etc/fstab
osgce:/home    /home           nfs     rw,hard,bg,rsize=32768,wsize=32768,udp,nfsvers=3

• Servidor NTP

vi /etc/ntp.conf
# Permite acesso ao servidor para sincronizar mas nao permite modificacoes no servico
restrict default nomodify notrap noquery
# Permite acesso complete para a interface local
restrict 127.0.0.1
# Libera acesso a minha rede local
restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap
server pcdsh05.on.br
server ntp.cais.rnp.br
server ntp.puc-rio.br
server ntp1.pucpr.br
server ntp.pop-rs.rnp.br
driftfile /var/lib/ntp/drift
#Fim de arquivo
service ntpd start
chkconfig ntpd on

• Servidor DHCP

yum install dhcp
vim /etc/dhcp.conf

• SendMail

yum install sendmail sendmail-cf
chkconfig sendmail on
vim /etc/mail/sendmail.mc
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
DAEMON_OPTIONS(`Port=smtp,Addr=192.168.1.155, Name=MTA')dnl
DAEMON_OPTIONS(`Port=smtp,Addr=200.136.80.2, Name=MTA')dnl
dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')
dnl FEATURE(`accept_unresolvable_domains')dnl
dnl define(`SMART_HOST',`mail.my-site.com')
vim  /etc/mail/access
Connect:192.168.1                       RELAY
vim  /etc/mail/virtusertable
sprace.org.br  root
@grid   root
vim /etc/mail/local-host-names
sprace.org.br
grid
vim /etc/aliases
root@spsrv01.grid
cd /etc/mail
make
newaliases
/etc/init.d/sendmail restart

Nos nodes instale o sendmail-cf e replicar a configuracao abaixo:

vim /etc/mail/sendmail.mc
define(`SMART_HOST', `[spserv01.sprace.org.br]')dnl
cd /etc/mail
make
newaliases
/etc/init.d/sendmail restart

OBS foi necessário remover o /var/mail/sendmail* de alguns nodes

• Servidor de Boot Remoto

Para a instalacao dos nodes usando PXE é necessario instalar

yum install tftp-server -y
vim /etc/xinetd.d/tftp
disable=no
yum install syslinux
cp /usr/lib/syslinux/pxelinux.0 /tftpboot/.
mkdir /tftpboot/pxelinux.cfg
chmod a+r  /tftpboot/pxelinux.cfg
cd /tftpboot
vim pxelinux.cfg/default
# timeout de espera
TIMEOUT 10
# Sempre mostrar o prompt
PROMPT  1
# Default e' realizar a instalacão
DEFAULT linux 
LABEL linux
     kernel vmlinuz1
    append ks=nfs:192.168.1.150:/tftpboot/kickstart/ks_32bits.cfg initrd=initrd1.img  devfs=nomount ksdevice=eth1
LABEL boot
    LOCALBOOT 0

Dentro desse diretório /tftpboot devem ficar o kernel e a imagem initrd que voce deseja bootar (No caso do Scientific Linux, procure no repositório por images/SL/pxeboot/vmlinuz e images/SL/pxeboot/initrd.img

ls /tftpboot/
initrd.img  msgs  pxelinux.0  pxelinux.cfg  vmlinuz 
mkdir /tftpboot/kickstart
cp ks_* /tftpboot/kickstart/.

A demora para passar pelo menu do TFTP até o default foi corrigida adicionando a seguinte linha no /etc/dhcpd.conf

 next-server 192.168.1.155;

• Servidor GUMS

cd /opt
wget http://atlas.bu.edu/~youssef/pacman/sample_cache/tarballs/pacman-3.28.tar.gz

• Servidor OSG-RSV

cd /opt/osg-serv/
pacman -get http://vdt.cs.wisc.edu/vdt_200_cache:OSG-RSV

Novamente na osg-ce

cert-gridadmin -service rsv -host spserv01.sprace.org.br  -prefix rsv-spserv-grid ca doegrids -affiliation osg -vo dosar -show -email mdias@ift.unesp.br

scp rsv-spserv01-gridkey.pem 192.168.1.155:/etc/grid-security/rsvkey.pem

Para instalar o RSV como servico seguimos as instrucoes de configuracao em https://twiki.grid.iu.edu/twiki/bin/view/MonitoringInformation/MapServiceCertToRsvuser capturando o DN com openssl x509 -text -subject -in /etc/grid-security/rsvcert.pem

Retornando à spserv01

cd ${VDT_LOCATION}/osg-rsv/bin/
source ${VDT_LOCATION}/setup.sh
$VDT_LOCATION/osg-rsv/setup/configure_osg_rsv --user rsvuser --init --server y -ce-probes --ce-uri "osg-ce.sprace.org.br" --srm-probes --srm-uri "osg-se.sprace.org.br" --srm-dir /pnfs/sprace.org.br/data/mdias --gratia --grid-type "OSG" --consumers --verbose --setup-for-apache --use-rsv-cert --gridftp-probes --rsv-cert-file /etc/grid-security/rsvcert.pem --rsv-key-file /etc/grid-security/rsvkey.pem --gratia-probes "condor managedfork metric gridftp-transfer" --setup-from-svn
vdt-control --enable condor-cron osg-rsv apache
vdt-control --on condor-cron osg-rsv apache

Necessário registrar essa maquina no OIM (Site do OSG para registro de resources) e esperar que este seja ativado. Surgiram problemas que a mesma não estava enviando o report para o site MyOSG, consertado com

$VDT_LOCATION/vdt/setup/configure_gratia --probe metric --report-to rsv.grid.iu.edu:8880

• Frontier-Squid

upload das informações para o CVS do CERN usando http://www.sprace.org.br/Twiki/bin/view/Main/EntryDescriptionNo64. Necessário também enviar um Savannah ticket (frontier) como "bug" informando sobre esta nova maquina. --++ Instalação dos nodes
