4.7.2 Configure sendmail (Required)
LSF HPC requires a mail program to send job output to users subm itting jobs and to send
administrative m essages to the LSF administrator.
By default, LSF HPC uses the mail program /usr/lib/sendmail.Thesendmail service
is installed by default on the head node in /usr/lib/sendmail, but you must configure
it to meet your site requirements. There are no special configuration requirem ents for an XC
system. Refer to any third-party Linux adm in istration reference manual if you n eed more
information about configuring sendmail.
To use a mail program oth er th an sendmail, you must set the LSB_MAILPROG variable in
the /opt/hptc/lsf/top/conf/lsf.conf file to the appropria te m a il pro g r am after the
system configuration is complete.
It may be necessary for users to have .forward files in their ho me directories to specify
where mail is to b e sent in o rder for the sendmail service to properly forward mail to users.
4.7.3 Create Local User Accounts (Optional)
If you intend to create l ocal user accounts on your XC system rather than m anage user accounts
through another user auth entication method (such as NIS or LD AP), use the Linux adduser
command to create local user accounts on the system now before the system is configured.
See the HP XC System So ftware Administration Guide if you need more information about
creating l ocal user accounts.
4.7.4 Configure NIS (Optio nal)
This section describes how to configure a slave NIS server on the head node and configure all
other nodes to be NIS clients of the internal slave NIS server. Performing this task now enables
the NIS co nfiguration to be p ropagated in to the golden image and subsequently imaged out to
all client n odes.
Enabling N IS before running the cluster_config util ity enabl es you to select a NIS
account as the prim ary LSF administrator during the cluster configuration process.
Perform this p roced ure as the root user on the head node:
1. Use t he text editor of your choice to add appropriate entries for your master NIS server to
the /etc/hosts file in the following format:
ip_address fully_qualified_NIS_server_name NIS_server_name
2. Save your changes and exit the file.
3. Use th e text editor of your c hoi ce to edit t he /etc/sysconfig/network file so
that it looks as fo llows:
NISDOMAIN=domain_name
OTHER_YPBIND_OPTS="-p 830"
YPSERV_ARGS="-p 831"
YPXFRD_ARGS="-p 832"
These settings cause the yp c lient to bind to port 830, the y p server to bind t o port 831,
and th e yp transfer service to bind to port 8 32, thu s allowing deterministic rules to be
configured in the firewall.
4. Save your changes and exit the file.
