99 Add a group for globus by executing: groupadd -g 900 globus Add the user globususer (with password globususer) by executing: adduser -u 900 -g globus -d /home/globususer -n globususer Change the globususer ID’s password from globususer to pwsbm1 or other password by executing: passwd globususer B.2.3 Installing Network Time Protocol (NTP) NTP needs to be installed because the grid needs the clocks on the systems to be synchronized. The security process creates proxy certificates that are valid for specific times. If the systems do not have their clocks synchronized, then the users may not be able to use the grid, because the proxy certificates may look like they have expired or are not yet valid. On all of the grid machines, install NTP as follows using the root ID: $ rpm -ivh /usr/src/ntp-4.1.1-1.i386.rpm If the package is already installed as a part of the Linux distribution, ignore the error message and continue to set up the NTP server. Proceed by setting up the server and daemons. Edit the file /etc/ntp.conf on the machine designated to be the time server, machine m2, and leave the following four lines as the only un-commented ones, commenting all others with a leading “#” character: server 127.127.1.0 # local clock fudge 127.127.1.0 stratum 10 driftfile /etc/ntp/drift broadcastdelay 0.008 Also, on the NTP server machine (m2), use the settings ntsysv command to enable the NTP daemon (ntpd) on the next reboot. We can also start the Red Hat Service Configuration tool by clicking on Main Menu System Setting Server Setting Services. Scroll down the list of services on the left side until we get to the ntpd service. Click on the ntpd service and click Start to run it. On the other machines in the grid (m1 and m3), change the file /etc/ntp.conf to leave only the following lines un-commented: server m2.kmitnb.ac.th driftfile /etc/ntp/drift
100 broadcastdelay 0.008 authenticate no Next, execute the following command to have them check for the time from the above server machine m2: ntpdate -b m2.kmitnb.ac.th This should be executed at least once per boot, and could be set up to run periodically using crond and crontab. B.2.4 Setting Up Host Files and Environment Variables on Each Machine As root, use an editor to edit the hosts file /etc/hosts on each machine with the following lines: 127.0.0.1 localhost 192.168.10.241 m1.kmitnb.ac.th m1 192.168.10.242 m2.kmitnb.ac.th m2 192.168.10.243 m3.kmitnb.ac.th m3 Verify machine connectivity after the next reboot, using the ping command to ping each of the other machines by name. Edit the file /etc/profile in each machine. Insert the following three lines after the line in /etc/profile that says “export PATH USER ...”: export GPT_LOCATION=/usr/local/gpt export GLOBUS_LOCATION=/usr/local/globus export PATH=$PATH:$GLOBUS_LOCATION/bin:$GLOBUS_LOCATION/sbin Log off and log back on the machines after modifying the file /etc/profile so that the above settings take effect. B.2.5 Installing the GPT Log on as root and install GPT on all of the machines. Please ignore all warnings from Globus: cd /usr/src tar -xzvf gpt-2.2.2-src.tar.gz cd gpt-2.2.2 ./build_gpt ls ${GPT_LOCATION}/sbin | wc -l The final ls command should show 29 gpt-* executable files. B.2.6 Installing a Globus Server Bundle The following is used to install the server bundle on each server machine. Perform these steps on each machine that will be a server. In our demo, we will use machines m2 and m3 as servers.
