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.

#

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
