还是大家常说的那句：生产环境千万记得备份哈~~~
以下的环境，是我的测试环境，这里就不备份啦~
这个当然不用多说：下载、上传到服务器、解压
mkdir -p /u01/app/11.2.0.4/grid
chown -R grid:oinstall /u01/app/11.2.0.4
chmod -R 775 /u01/app/11.2.0.4
[root@RAC01 ~]# cat /etc/hosts
# Do not remove the following line, or variousprograms

如果检查出错误，请根据提示修复。
需要保证所有节点的GI都正常运行
[grid@RAC01 ~]# su – grid
[grid@RAC01 ~]$ unset ORACLE_BASE
[grid@RAC01 ~]$ unset ORACLE_SID
[grid@Oracle-LAB ~]$ cd /software/grid/
[grid@Oracle-LAB grid]$ ./runInstaller
注意：如果在上面一个步骤上点“Next”出现下图错误：
