RAC安装需执行的脚本及意义

RAC安装需执行的脚本及意义

安装CRS时需要执行3个脚本

1)   $ORACLE_BASE/oraInventory/orainstRoot.sh

2)   $CRS_HOME/root.sh

3)   $CRS_HOME/bin/vipca.sh（该脚本是在第二个节点执行$CRS_HOME/root.sh时被自动调用

 

root@lxsfrac04 # /oracle/oraInventory/orainstRoot.sh

Changing permissions of /oracle/oraInventory to 770.

Changing groupname of /oracle/oraInventory to oinstall.

The execution of the script is complete

 

root@lxsfrac03 # more  /oracle/oraInventory/orainstRoot.sh

#!/bin/sh

if [ ! -d "/var/opt/oracle" ]; then

mkdir -p /var/opt/oracle;

fi

if [ -d "/var/opt/oracle" ]; then

chmod 755 /var/opt/oracle;

fi

if [ -f "/oracle/oraInventory/oraInst.loc" ]; then

cp /oracle/oraInventory/oraInst.loc /var/opt/oracle/oraInst.loc;

chmod 644 /var/opt/oracle/oraInst.loc;

else

INVPTR=/var/opt/oracle/oraInst.loc

INVLOC=/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 /oracle/oraInventory to 770.";

chmod -R 770 /oracle/oraInventory;

if [ $? != 0 ]; then

 echo "OUI-35086:WARNING: chmod of /oracle/oraInventory to 770 failed!";

fi

echo "Changing groupname of /oracle/oraInventory to oinstall.";

chgrp oinstall /oracle/oraInventory;

if [ $? != 0 ]; then

 echo "OUI-10057:WARNING: chgrp of /oracle/oraInventory to oinstall failed!";

fi

echo "The execution of the script is complete"

 

从脚本我们可以看出，这个脚本主要是创建/var/opt/oracle目录（如果不存在的话）,再在该目录下建oraInst.loc文件（该文件记录orainventory的位置和组）。并改变orainventory的属性。

root@lxsfrac04 # ls –rlt /var/opt/oracle/

root@lxsfrac04 # more oraInst.loc

inventory_loc=/oracle/oraInventory

inst_group=oinstall

 

在另一个节点上运行该脚本

root@lxsfrac03 # /oracle/oraInventory/orainstRoot.sh

Changing permissions of /oracle/oraInventory to 770.

Changing groupname of /oracle/oraInventory to oinstall.

The execution of the script is complete

    从输出我们可以看出，该脚本主要执行crs的配置，格式化ocr disk,更新/etc/inittab文件，启动css进程，在/var/opt/oracle/新建了ocr.loc文件及，scls_scr，oprocd文件夹。

    查看crs进程及/etc/inittab文件可以看出节点的变化。

该脚本会将inittab复制为inittab.no_crs,修改后的inittab另复制一份为inittab.crs.

 

 

在另外一个节点执行$CRS_HOME/root.sh

在第二个节点上运行时会多比在第一个节点上运行多执行一个任务-------运行$CRS_HOME/bin/vipca.sh

这也是rac安装中的一个重要脚本。
VIPCA.sh主要是配置vip并启动crs的默认资源（未建库时默认为6个）,多启动三个后台进程。

从现在lxsfrac04上的进程就能看出，执行完vipca.sh后，会多出三个红色的后台进程。

安装数据库软件（binary）时需在最后一步

执行$ORACLE_HOME/root.sh

root@lxsfrac04 # $ORACLE_HOME/root.sh

该脚本的作用在于在指定的目录(默认为/usr/local/bin)下创建dbhome,oraenv,coraenv,在/var/opt/oracle/里创建oratab文件。

上述的4个脚本对于安装rac有着重要的意义，应该仔细理解。
