重新安装grid

王硕

对于已经安装一半而没有成功的grid 软件处理：
*******************************方案一********************************

******两个节点运行：（root用户）
        cd /etc/oracle
        rm -fr *
        重新创建目录:
        mkdir -p /u01/app/grid
        mkdir -p /u01/app/11.2.0/grid
        chown -R grid.oinstall /u01
        mkdir -p /u01/app/oracle
        chown -R oracle.oinstall /u01/app/oracle
        chmod -R 775 /u01/
        将u01  改为
        mkdir -p /u02/app/grid
        mkdir -p /u02/app/11.2.0/grid
        chown -R grid.oinstall /u02
        mkdir -p /u02/app/oracle
        chown -R oracle.oinstall /u02/app/oracle
        chmod -R 775 /u02/

        更改grid  用户.bash_profile 文件

        scan可能会被占用，可修改scan名字

        
        rac-vip也可能会被占用，可选择更改地址，生产环境慎重考虑。
        DATA组可能会被占用，小编改为了DATA2


INS-40724 No locally defined network interface matches the SCAN address

修改/etc/hosts  scan
重新打开runInstall 安装

********************************方案一**********************************

********************************方案二**********************************
1、清空/u01/11.2.0/grid目录
  2、清空/u01/app/oracle目录
  3、清空/u01/app/grid目录
  4、删除/etc/ora开头的文件和目录
  5、进入/etc/init.d/，把ohasd文件删除（否则这个文件会在开机时启动cluster）。

重新配置asm disk

root脚本出错

运行出错信息中rootcrs.pl这个脚本，只不过给它配上 -deconfig的参数，让它先把原先残余的东东清掉。
然后再重新执行root.sh就可以了。

成功执行，再执行root.sh，顺利通过！

一般选择第二种办法哈 。
