安装oracle 10g RAC执行的几个脚本说明

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

   printf "   [-crsgroup <Name of the user-group installing Oracle CRS>]\n"
}

validateInput()

   valid=`$ECHO $1 | $AWK '/^%/ { print "false"; }'`
   if [ "$valid" = "false" ];
   then

      usage;
      return 1;

}

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
