1，/u01/app/oracle/oraInventory/orainstRoot.sh 脚本
#!/bin/sh if [ -d "/etc" ]; then chmod 755 /etc; fi if [ -f "/u01/app/oracle/oraInventory/oraInst.loc" ]; then cp /u01/app/oracle/oraInventory/oraInst.loc /etc/oraInst.loc; else INVPTR=/etc/oraInst.loc INVLOC=/u01/app/oracle/oraInventory GRP=oinstall PTRDIR="`dirname $INVPTR`"; # Create the software inventory location pointer file if [ ! -d "$PTRDIR" ]; then mkdir -p $PTRDIR; fi echo "Creating the Oracle inventory pointer file ($INVPTR)"; echo inventory_loc=$INVLOC > $INVPTR echo inst_group=$GRP >> $INVPTR chmod 644 $INVPTR # Create the inventory directory if it doesn't exist if [ ! -d "$INVLOC" ];then echo "Creating the Oracle inventory directory ($INVLOC)"; mkdir -p $INVLOC; fi fi echo "Changing permissions of /u01/app/oracle/oraInventory to 770."; chmod -R 770 /u01/app/oracle/oraInventory; if [ $? != 0 ]; then echo "OUI-35086:WARNING: chmod of /u01/app/oracle/oraInventory to 770 failed!"; fi echo "Changing groupname of /u01/app/oracle/oraInventory to oinstall."; chgrp oinstall /u01/app/oracle/oraInventory; if [ $? != 0 ]; then echo "OUI-10057:WARNING: chgrp of /u01/app/oracle/oraInventory to oinstall failed!"; fi echo "The execution of the script is complete"
从上面的脚步中可以看出，这个脚本的作用是/etc/oraInst.loc文件，并修改/etc和/u01/app/oracle/oraInventory 的权限
2./u01/crs1020/root.sh 脚步
脚本如下：
#!/bin/sh /u01/crs1020/install/rootinstall /u01/crs1020/install/rootconfig
调用上面的两个脚本
/u01/crs1020/install/rootinstall 如下
#!/bin/sh # # rootinstall.sbs for CRS installs # # This is run once per CRS_HOME during the install. This install specific # root script sets file ownerships, groups, and permissions on # the files or directories that are to be owned by root user. # SILENT=false CRS_ORACLE_HOME=/u01/crs1020 CRS_ORACLE_OWNER=oracle CRS_DBA_GROUP=oinstall if [ -z "$CHOWN" ]; then CHOWN=/bin/chown; fi if [ -z "$CHGRP" ]; then CHGRP=/bin/chgrp; fi if [ -z "$CHMOD" ]; then CHMOD=/bin/chmod; fi if [ -z "$ECHO" ]; then ECHO=/bin/echo; fi if [ -z "$AWK" ]; then AWK=/bin/awk; fi if [ -z "$LS" ]; then LS=/bin/ls; fi if [ -z "$ID" ]; then ID=/usr/bin/id; fi if [ -z "$MKDIRP" ]; then MKDIRP="/bin/mkdir -p"; fi usage() { printf "Usage:" printf "$0 [-silent]\n" printf " [-crshome <Oracle CRS home path>]\n" printf " [-crsuser <Name of the user installing Oracle CRS>]\n" printf " [-crsgroup <Name of the user-group installing Oracle CRS>]\n" } validateInput() { ##validates if any value is assigned to the script variables valid=`$ECHO $1 | $AWK '/^%/ { print "false"; }'` if [ "$valid" = "false" ]; then $ECHO "No value set for the CRS parameter $2. Use parameter file to set values"; usage; return 1; fi return 0; } # This script is intended to be run by root. RUID=`$ID|$AWK -F\( '{print $2}'|$AWK -F\) '{print $1}'` if [ ${RUID} != "root" ];then $ECHO "You must be logged in as root to run $0." $ECHO "Log in as root and restart $0 execution." exit 1 fi UNAME=/bin/uname PLATFORM=`$UNAME` case $PLATFORM in Linux) DIRNAME=/usr/bin/dirname ;; HP-UX) DIRNAME=/bin/dirname ;; SunOS) DIRNAME=/bin/dirname ;; AIX) DIRNAME=/bin/dirname ;; OSF1) DIRNAME=/usr/bin/dirname ;; *) DIRNAME=/bin/dirname ;; esac USER_ARGS=$* while [ $# -gt 0 ]; do if [ $1 = "-silent" ]; then SILENT=1; elif [ $1 = "-crshome" ]; then if [ $# -ge 2 ]; then CRS_ORACLE_HOME=$2; shift; else usage; exit 2 fi elif [ $1 = "-crsuser" ]; then if [ $# -ge 2 ]; then CRS_ORACLE_OWNER=$2; shift; else usage; exit 2 fi elif [ $1 = "-crsgroup" ]; then if [ $# -ge 2 ]; then CRS_DBA_GROUP=$2; shift; else usage; exit 2 fi else usage; exit 2 fi shift; done validateInput $CRS_ORACLE_HOME "CRS_ORACLE_HOME" || { $ECHO $?; exit 1; } validateInput $CRS_ORACLE_OWNER "CRS_ORACLE_OWNER" || { $ECHO $?; exit 1; } validateInput $CRS_DBA_GROUP "CRS_DBA_GROUP" || { $ECHO $?; exit 1; } ORA_CRS_HOME=$CRS_ORACLE_HOME export ORA_CRS_HOME CH=$ORA_CRS_HOME export CRS_ORACLE_HOME # set ownership to root, but give execute permissions to all $CHOWN root $CH/bin/crs* $CHMOD 555 $CH/bin/crs* # only owner(root) should ever invoke crsd $CHMOD 744 $CH/bin/crsd if [ ! -d $CH/crs/init ]; then $MKDIRP $CH/crs/init fi $CHOWN root $CH $CHMOD 755 $CH for d in bin crs crs/init crs/profile crs/script crs/template crs/auth do $CHOWN root $CH/$d $CHMOD 755 $CH/$d done # These are writeable by all for d in crs/public do $CHOWN $CRS_ORACLE_OWNER $CH/$d $CHMOD 777 $CH/$d done for d in evm evm/init do $CHMOD 750 $CH/$d done for d in css css/init css/log css/auth do $CHMOD 711 $CH/$d done # check directories above $CH are owned by root d=$CH while [ "$d" != "/" ] do d=`$DIRNAME $d` set -$- `$LS -ld $d` case $3 in root) ;; # ok *) $ECHO "WARNING: directory '$d' is not owned by root";; esac done主要是对CRS需要的一些目录权限进行配置
/u01/crs1020/install/rootconfig这个脚本主要是对CRS进行配置，使CRS服务在服务器重启时自动启动，加入/etc/inittab ，格式化Voting disk等
