# Post Install Scripts # # The Post Install Scripts table is a rules-based system for determining # which install scripts and in what order to execute them. # # Rules and actions are formatted: # # RULE { # script [args] # script [args] # script [args] # ... # } # # Rules are defined as VAR=REGEX. Where VAR may be any exported # environmental variable, ALL, or NODERANGE (special, see below). # # Regular expressions (REGEX or regex) are a powerful way to define a match. # The perl regex engine is used to parse the rules. Please do not confuse # regex with shell expansion characters. # # e.g. compute* does NOT match anything starting with 'compute' as bash # would. compute.* is the correct regex for a that match. man perlre for # regex docs. (BTW, regex compute* matches 'comput' with 0 or more 'e's at # the end.) # # There is no need to place beginning and end markers (^$) in your regex. # They are added automatically. # # Actions are defined as: script [optional args] # # A special action/script "STOP" will stop processing all rules and exit. # # Scripts are run top-down multiples rules can match. # # Nesting with () and operators and, or, and not are supported. # # The following VARs are exported by xCAT: # # OSVER=(rh62|rh70|rh71|rh72|rh73|rh80|suse81|sles8) # OSVER is the OS that has just been installed. OSVER may be defined by # regex. (e.g. rh.* is "anything starting with rh") # # ARCH=(x86|ia64) # ARCH is the hardware architecture (uname -m). ARCH may be defined by # regex. # # NODERANGE=(e.g. node1-node10) # NODERANGE follows the xCAT noderange format as defined by noderange.5 # (man noderange). Regex is supported as part of noderange, however it # must be prefixed with a '@', e.g. (@node.* is "anything starting with # node"). # # ALL (Apply to all) # # TABLE:TABLENAME:KEY:FIELD= # # The last rule is special and is determined at runtime. # # TABLENAME is the name of an xCAT table located in $XCATROOT/etc. You # may create your own tables. # # KEY is the first field of any xCAT table. $NODE is a # special value for key, usually the key is a fixed name, however many xCAT # tables start with a node or resource group name. # # FIELD is a numeric value for fields associated with KEY. The first field # is 1. Special names are available (e.g. $nodehm_eth0) and are defined in # $XCATROOT/lib/functions. Any environmental variable can be used. # # e.g.: # # TABLE:nodehm.tab:$NODENAME:$nodehm_eth0=e1000 # # Would only execute scripts where eth0 was defined as e1000 in nodehm.tab # for any node. # # The script $XCATROOT/bin/postage is the master post installation script # that parses this table and runs the scripts. You can use the script # $XCATROOT/bin/postrules NODENAME ARCH OSVER to parse this table to test # your rules. # # e.g. postrules node1 x86 rh73 # # Setup syslog OSVER=sl[34].* or OSVER=centos.* or OSVER=rh.* or OSVER=sles.* or OSVER=suse.* { syslog } # Setup servicenode NODERANGE=service { servicenode } # update/add packages OSVER=sl[34].* or OSVER=centos.* or OSVER=rh.* or OSVER=sles.* or OSVER=suse.* { updaterpms nodeps otherrpms forcerpms } # setup NFS mounts OSVER=sl[34].* or OSVER=centos.* or OSVER=rh.* or OSVER=sles.* or OSVER=suse.* { nfsmounts } # sync clock OSVER=sl[34].* or OSVER=centos.* or OSVER=rh.* or OSVER=sles.* or OSVER=suse.* { syncclock setupntp } # Setup PAM TABLE:noderes:$NODE:access=Y and (OSVER=sl[34].* or OSVER=centos.* or OSVER=rh.* or OSVER=sles.* or OSVER=suse.*) { setuppam } # Setup PBS TABLE:noderes:$NODE:pbs=Y and (OSVER=sl[34].* or OSVER=centos.* or OSVER=rh.* or OSVER=sles.* or OSVER=suse.*) { openpbs } # Setup paths OSVER=sl[34].* or OSVER=centos.* or OSVER=rh.* or OSVER=sles.* or OSVER=suse.* { setuppaths } # Setup services OSVER=sl[34].* or OSVER=centos.* or OSVER=rh.* or OSVER=sles.* or OSVER=suse.* { setupservices } # Setup rsh/ssh.
