[클러스터] Sun Grid Engine(SGE)-5.3 설치하기

SGE 설치하기 [[목차]]

1.1. 공통사항 [[목차]]

1) 관리 계정 만들기

설치하려는 클러스터의 모든 노드에 sge라는 계정을 추가한다.

# adduser sge

# passwd sge

2) 서비스 포트 추가

설치하려는 클러스터의 모든 노드의 /etc/services 화일에 sge_commd를 위한

포트를 지정한다. 가능하면 1024번 이하의 포트를 지정한다.

모든 노드가 같은 포트번호를 사용하여야 한다.

# vi /etc/services



sge_commd 536/tcp # Sun Grid Engine

:wq

1.2. 마스터 노드에 설치하기 [[목차]]

주의>>

SGE는 NFS로 마운트되어 공유되고 있는 파일 시스템상에 설치해야 한다.

보통 클러스터의 경우 /home 파티션을 공유해서 사용하므로,

/home/sge/SGE 에 설치를 하도록 한다.

1) 다운로드 및 압축 풀기

설치화일은

http://wwws.sun.com/software/gridware/

http://gridengine.sunsource.net/

에서 다운로드가 가능하다.

커널 2.4의 glibc 2.1이상의 x86 리눅스의 경우 sge-5.3p2-common.tar.gz 와

sge-5.3p2-bin-glinux.tar.gz 를 다운 받는다.

sge 계정으로 로그인하여 압축을 푼다.

# su sge

$ mkdir /home/sge/SGE

$ cd /home/sge/SGE

$ tar zxvf sge-5.3p2-common.tar.gz

$ tar zxvf sge-5.3p2-bin-glinux.tar.gz

$ exit

2) install_qmaster 실행

SGE_ROOT 환경 변수를 설정한다.

# export SGE_ROOT=/home/sge/SGE

SGE는 설치 프로그램을 이용하여 설치된다.

마스터 노드에 설치할때는 install_qmaster를, 계산노드에 설치할때는

install_execd를 실행한다.

install_qmaster를 실행한다.

# ./install_qmaster

Welcome to the Grid Engine installation

Hit <RETURN> to continue >> Enter

Select default Grid Engine hostname resolving method

—————————————————-

Are all hosts of your cluster in one DNS domain? If this is

the case the hostnames

>hostA< and >hostA.foo.com<

would be treated as equal, because the DNS domain name >foo.com<

is ignored when comparing hostnames.

Are all hosts of your cluster in a single DNS domain (y/n) [y] >> Enter

Ignoring domainname when comparing hostnames.

Hit <RETURN> to continue >> Enter

Grid Engine group id range

————————–

When jobs are started under the control of Grid Engine an additional group id

is set on platforms which do not support jobs.

This additional UNIX group id range must be unused group id’s in your system.

The range must be big enough to provide enough numbers for the maximum number

of Grid Engine jobs running at a single moment on a single host. E.g. a range

like >20000-20100< means, that Grid Engine will use the group id’s from

20000-20100 and thus provides a range for 101 jobs running at the same time

on a single host.

You can change at any time the group id range in your cluster configuration.

Please enter a range >> 20000-20100

Using >20000-20100< as gid range. Hit <RETURN> to continue >> Enter

Creating local configuration

—————————-

Creating >act_qmaster< file

Adding default complexes >host< and >queue<

Please now add the list of hosts, where you will later install your execution

daemons. These hosts will be also added as valid submit hosts.

Please enter a blank separated list of your execution hosts. You may

press <RETURN> if the line is getting too long. Once you are finished

simply press <RETURN> without entering a name.

You also may prepare a file with the hostnames of the machines where you plan

to install Grid Engine. This may be convenient if you are installing Grid

Engine on many hosts.

Do you want to use a file which contains the list of hosts (y/n) [n] >> Enter

Adding admin and submit hosts

—————————–

Please enter a blank seperated list of hosts.

Stop by entering <RETURN>. You may repeat this step until you are

entering an empty list. You will see messages from Grid Engine

when the hosts are added.

Finished adding hosts. Hit <RETURN> to continue >> Enter

Using Grid Engine

—————–

You should now enter the command:

source /home/sge/SGE/default/common/settings.csh

if you are a csh/tcsh user or

# . /home/sge/SGE/default/common/settings.sh

if you are a sh/ksh user.

This will set or expand the following environment variables:

– $SGE_ROOT (always necessary)

– $SGE_CELL (if you are using a cell other than >default<)

– $COMMD_PORT (if you haven’t added the service >sge_commd<)

– $PATH/$path (to find the Grid Engine binaries)

– $MANPATH (to access the manual pages)

Hit <RETURN> to see where Grid Engine logs messages >> Enter

Grid Engine messages

——————–

Grid Engine messages can be found at:

/tmp/qmaster_messages (during qmaster startup)

/tmp/execd_messages (during execution daemon startup)

After startup the daemons log thier messages in their spool directories.

Qmaster: /home/sge/SGE/default/spool/qmaster/messages

Exec daemon: //messages

Do you want to see previous screen about using Grid Engine again (y/n) [n] >> Enter

Your Grid Engine qmaster installation is now completed

——————————————————

Please now login to all hosts where you want to run an execution daemon

and start the execution host installation procedure.

If you want to run an execution daemon on this host, please do not forget

to make the execution host installation in this host as well.

All execution hosts must be administrative hosts during the installation.

All hosts which you added to the list of administrative hosts during this

installation procedure can now be installed.

You may verify your administrative hosts with the command

# qconf -sh

and you may add new administrative hosts with the command

# qconf -ah

# ./install_execd

Welcome to the Grid Engine execution host installation

——————————————————

If you haven’t installed the Grid Engine qmaster host yet, you must execute

this step (with >install_qmaster<) prior the execution host installation.

For a sucessfull installation you need a running Grid Engine qmaster. It is

also neccesary that this host is an administrative host.

You can verify your current list of administrative hosts with

the command:

# qconf -sh

You can add an administrative host with the command:

# qconf -ah

The execution host installation will take approximately 5 minutes.

Hit <RETURN> to continue >> Enter

Grid Engine admin user account

——————————

The current directory

/home/sge/SGE

is owned by user

sge

If user >root< does not have write permissions in this directory on *all*

of the machines where Grid Engine will be installed (NFS partitions not

exported for user >root< with read/write permissions) it is recommended to

install Grid Engine that all spool files will be created under the user id

of user >sge<.

IMPORTANT NOTE: The daemons still have to be started by user >root<.

Do you want to install Grid Engine as admin user >sge< (y/n) [y] >> Enter
